自定义弹窗
既然时弹窗,那就不能让它平白无奇的出现,给一个动画效果,闪亮登场,完美谢幕。
in_bottom_to_top.xml
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500"
android:fromYDelta="100%p"
android:interpolator="@android:anim/accelerate_interpolator"
android:toYDelta="0%p" >
</translate>
in_right_to_left.xml
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500"
android:fromXDelta="100%p"
android:interpolator="@android:anim/accelerate_interpolator"
android:toXDelta="0%p" >
</translate>
out_left_to_right.xml
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500"
android:fromXDelta="0%p"
android:toXDelta="100%p"
android:interpolator="@android:anim/accelerate_interpolator" >
</translate>
out_top_to_bottom.xml
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500"
android:fromYDelta="0%p"
android:toYDelta="100%p"
android:interpolator="@android:anim/accelerate_interpolator" >
</translate>
然后在模块的styles.xml中增加样式
<!--弹窗样式-->
<style name="AnimationRightFade"><!--右侧-->
<item name="android:windowEnterAnimation">@anim/in_right_to_left</item> <!--打开动画-->
<item name="android:windowExitAnimation">@anim/out_left_to_right</item> <!--关闭动画-->
</style>
<style name="AnimationBottomFade"><!--底部-->
<item name="android:windowEnterAnimation">@anim/in_bottom_to_top</item>
<item name="android:windowExitAnimation">@anim/out_top_to_bottom</item>
</style>
然后在模块的utils包中新建一个LiWindow类
代码如下:
package com.llw.mvplibrary.utils;
import android.app.Activity;
import android.content.Context;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;
import android.widget.PopupWindow;
import com.llw.mvplibrary.R;
import java.util.HashMap;
import java.util.Map;
/**
* 自定义弹窗
*/
public class LiWindow {
private LiWindow mLiWindow;
private PopupWindow mPopupWindow;
private LayoutInflater inflater;
private View mView;
private Context mContext;
private WindowManager show;
WindowManager.LayoutParams context;
private Map<String,Object> mMap = new HashMap<>();
public Map<String, Object> getmMap() {
return mMap;
}
public LiWindow(Context context){
this.mContext = context;
inflater = LayoutInflater.from(context);
mLiWindow = this;
}
public LiWindow(Context context, Map<String,Object> map){
this.mContext = context;
this.mMap = map;
inflater = LayoutInflater.from(context);
}
/**
* 右侧显示 自适应大小
* @param mView
*/
public void showRightPopupWindow(View mView) {
mPopupWindow = new PopupWindow(mView,
ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT , true);
mPopupWindow.setContentView(mView);
mPopupWindow.setOutsideTouchable(true);//点击空白处不关闭弹窗 true为关闭
mPopupWindow.setFocusable(true);
mPopupWindow.setAnimationStyle(R.style.AnimationRightFade); //设置动画
mPopupWindow.showAtLocation(mView, Gravity.RIGHT,0 ,0);
setBackgroundAlpha(0.5f,mContext);
WindowManager.LayoutParams nomal = ((Activity) mContext).getWindow().getAttributes();
nomal.alpha = 0.5f;
((Activity) mContext).getWindow().setAttributes(nomal);
mPopupWindow.setOnDismissListener(closeDismiss);
}
/**
* 右侧显示 高度占满父布局
* @param mView
*/
public void showRightPopupWindowMatchParent(View mView) {
mPopupWindow = new PopupWindow(mView,
ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT , true);
mPopupWindow.setContentView(mView);
mPopupWindow.setOutsideTouchable(true);//点击空白处不关闭弹窗 true为关闭
mPopupWindow.setFocusable(true);
mPopupWindow.setAnimationStyle(R.style.AnimationRightFade); //设置动画
mPopupWindow.showAtLocation(mView, Gravity.RIGHT,0 ,0);
setBackgroundAlpha(0.5f,mContext);
WindowManager.LayoutParams nomal = ((Activity) mContext).getWindow().getAttributes();
nomal.alpha = 0.5f;
((Activity) mContext).getWindow().setAttributes(nomal);
mPopupWindow.setOnDismissListener(closeDismiss);
}
/**
* 底部显示
* @param mView
*/
public void showBottomPopupWindow(View mView) {
mPopupWindow = new PopupWindow(mView,
ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);
mPopupWindow.setContentView(mView);
mPopupWindow.setOutsideTouchable(true);//点击空白处不关闭弹窗 true为关闭
mPopupWindow.setFocusable(true);
mPopupWindow.setAnimationStyle(R.style.AnimationBottomFade); //设置动画
mPopupWindow.showAtLocation(mView, Gravity.BOTTOM, 0, 0);
setBackgroundAlpha(0.5f,mContext);
WindowManager.LayoutParams nomal = ((Activity) mContext).getWindow().getAttributes();
nomal.alpha = 0.5f;
((Activity) mContext).getWindow().setAttributes(nomal);
mPopupWindow.setOnDismissListener(closeDismiss);
}
public static void setBackgroundAlpha(float bgAlpha,Context mContext){
WindowManager.LayoutParams lp = ((Activity) mContext).getWindow().getAttributes();
lp.alpha = bgAlpha;
((Activity) mContext).getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
((Activity) mContext).getWindow().setAttributes(lp);
}
/**
* 设置弹窗动画
* @param animId
* @return showPopu
*/
public LiWindow setAnim(int animId) {
if (mPopupWindow != null) {
mPopupWindow.setAnimationStyle(animId);
}
return mLiWindow;
}
//弹窗消失时关闭阴影
public PopupWindow.OnDismissListener closeDismiss = new PopupWindow.OnDismissListener() {
@Override
public void onDismiss() {
WindowManager.LayoutParams nomal = ((Activity)mContext).getWindow().getAttributes();
nomal.alpha = 1f;
((Activity)mContext).getWindow().setAttributes(nomal);
}
};
public void closePopupWindow() {
if (mPopupWindow != null) {
mPopupWindow.dismiss();
}
}
/*
使用方法
* LiWindow liWindow = new LiWindow(MainActivity.this);
View mView = LayoutInflater.from(MainActivity.this).inflate(R.layout.center_layout,null);
liWindow.showCenterPopupWindow(mView);
* */
}
弹窗也是需要布局文件的,现在创建一个新的布局文件,用于显示城市列表。 返回图标:
在项目的layout下创建一个名为window_city_list.xml的布局文件 代码如下:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:fitsSystemWindows="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:orientation="vertical"
android:background="#FFF"
android:layout_width="240dp"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:contentInsetLeft="16dp"
app:popupTheme="@style/AppTheme.PopupOverlay">
<TextView
android:id="@+id/tv_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textSize="16sp"
android:textColor="#000"
android:text="中国" />
</androidx.appcompat.widget.Toolbar>
<!--城市列表的返回-->
<ImageView
android:visibility="gone"
android:layout_marginLeft="@dimen/dp_10"
android:layout_centerVertical="true"
android:id="@+id/iv_back_city"
android:src="@mipmap/icon_page_return"
android:padding="15dp"
android:layout_width="40dp"
android:layout_height="40dp"/>
<!--区/县列表的返回-->
<ImageView
android:visibility="gone"
android:layout_marginLeft="@dimen/dp_10"
android:layout_centerVertical="true"
android:id="@+id/iv_back_area"
android:src="@mipmap/icon_page_return"
android:padding="15dp"
android:layout_width="40dp"
android:layout_height="40dp"/>
</RelativeLayout>
<View
android:layout_width="match_parent"
android:layout_height="0.5dp"
android:background="#EEEEEE"/>
<!--数据展示-->
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/rv"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
</RelativeLayout>
为了让点击的时候有一个效果,在模块的res文件下的drawable下创建一个rounded_corners.xml的样式文件,点击的水波纹效果
代码如下
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape android:shape="rectangle">
<solid android:color="#18ffc400"/>
</shape>
</item>
<item android:state_focused="true" android:state_enabled="true">
<shape android:shape="rectangle">
<solid android:color="#0f000000"/>
</shape>
</item>
</selector>
接下来在res文件下下新建一个drawable-v21的文件夹,文件夹下创建一个bg_white.xml
代码如下:
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#20000000"
android:drawable="@drawable/rounded_corners"/>
点击的样式做好了,接下来创建城市列表的item 在项目的layout文件夹下创建一个名为item_city_list.xml的布局文件
代码如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/item_city"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#FFF"
android:orientation="vertical">
<!--显示省 、 市 、 区/县-->
<TextView
android:id="@+id/tv_city"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:foreground="@drawable/bg_white"
android:gravity="center"
android:padding="10dp"
android:textColor="#FF000000"
android:textSize="15sp" />
<!--分隔线-->
<View
android:layout_width="match_parent"
android:layout_height="0.5dp"
android:background="#EEEEEE"/>
</LinearLayout>
接下来就是要创建一个实体Bean用来接收JSON中解析出来的城市数据,里面包含了省、市、区/县 在项目的bean包下新建一个CityResponse
代码如下:
package com.llw.goodweather.bean;
import java.util.List;
public class CityResponse {
/**
* name : 北京市
* city : [{"name":"北京市","area":["东城区","西城区","崇文区","宣武区","朝阳区","丰台区","石景山区","海淀区","门头沟区","房山区","通州区","顺义区","昌平区","大兴区","平谷区","怀柔区","密云县","延庆县"]}]
*/
private String name;
private List<CityBean> city;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<CityBean> getCity() {
return city;
}
public void setCity(List<CityBean> city) {
this.city = city;
}
public static class CityBean {
/**
* name : 北京市
* area : ["东城区","西城区","崇文区","宣武区","朝阳区","丰台区","石景山区","海淀区","门头沟区","房山区","通州区","顺义区","昌平区","大兴区","平谷区","怀柔区","密云县","延庆县"]
*/
private String name;
private List<AreaBean> area;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public static class AreaBean {
/**
* name : 北京市
* area : ["东城区","西城区","崇文区","宣武区","朝阳区","丰台区","石景山区","海淀区","门头沟区","房山区","通州区","顺义区","昌平区","大兴区","平谷区","怀柔区","密云县","延庆县"]
*/
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
}
}
接下来创建适配器,需要三个适配器,省、市、区/县。在adapter包下创建ProvinceAdapter、CityAdapter、AreaAdapter
ProvinceAdapter.java
package com.llw.goodweather.adapter;
import androidx.annotation.Nullable;
import com.chad.library.adapter.base.BaseQuickAdapter;
import com.chad.library.adapter.base.BaseViewHolder;
import com.llw.goodweather.R;
import com.llw.goodweather.bean.CityResponse;
import java.util.List;
/**
* 省列表适配器
*/
public class ProvinceAdapter extends BaseQuickAdapter<CityResponse, BaseViewHolder> {
public ProvinceAdapter(int layoutResId, @Nullable List<CityResponse> data) {
super(layoutResId, data);
}
@Override
protected void convert(BaseViewHolder helper, CityResponse item) {
helper.setText(R.id.tv_city,item.getName());//省名称
helper.addOnClickListener(R.id.item_city);//点击之后进入市级列表
}
}
CityAdapter.java
package com.llw.goodweather.adapter;
import androidx.annotation.Nullable;
import com.chad.library.adapter.base.BaseQuickAdapter;
import com.chad.library.adapter.base.BaseViewHolder;
import com.llw.goodweather.R;
import com.llw.goodweather.bean.CityResponse;
import java.util.List;
/**
* 市列表适配器
*/
public class CityAdapter extends BaseQuickAdapter<CityResponse.CityBean, BaseViewHolder> {
public CityAdapter(int layoutResId, @Nullable List<CityResponse.CityBean> data) {
super(layoutResId, data);
}
@Override
protected void convert(BaseViewHolder helper, CityResponse.CityBean item) {
helper.setText(R.id.tv_city,item.getName());//市名称
helper.addOnClickListener(R.id.item_city);//点击事件 点击进入区/县列表
}
}
AreaAdapter.java
package com.llw.goodweather.adapter;
import androidx.annotation.Nullable;
import com.chad.library.adapter.base.BaseQuickAdapter;
import com.chad.library.adapter.base.BaseViewHolder;
import com.llw.goodweather.R;
import com.llw.goodweather.bean.CityResponse;
import java.util.List;
/**
* 区/县列表适配器
*/
public class AreaAdapter extends BaseQuickAdapter<CityResponse.CityBean.AreaBean, BaseViewHolder> {
public AreaAdapter(int layoutResId, @Nullable List<CityResponse.CityBean.AreaBean> data) {
super(layoutResId, data);
}
@Override
protected void convert(BaseViewHolder helper, CityResponse.CityBean.AreaBean item) {
helper.setText(R.id.tv_city,item.getName());//区/县的名称
helper.addOnClickListener(R.id.item_city);//点击事件 点击之后得到区/县 然后查询天气数据
}
}
万事具备了,接下来就是在MainActivity.java里面实现这个城市弹窗数据的渲染了。
private List<String> list;//字符串列表
private List<CityResponse> provinceList;//省列表数据
private List<CityResponse.CityBean> citylist;//市列表数据
private List<CityResponse.CityBean.AreaBean> arealist;//区/县列表数据
ProvinceAdapter provinceAdapter;//省数据适配器
CityAdapter cityAdapter;//市数据适配器
AreaAdapter areaAdapter;//县/区数据适配器
String provinceTitle;//标题
LiWindow liWindow;//自定义弹窗
使用弹窗
/**
* 城市弹窗
*/
private void showCityWindow() {
provinceList = new ArrayList<>();
citylist = new ArrayList<>();
arealist = new ArrayList<>();
list = new ArrayList<>();
liWindow = new LiWindow(context);
final View view = LayoutInflater.from(context).inflate(R.layout.window_city_list, null);
ImageView areaBack = (ImageView) view.findViewById(R.id.iv_back_area);
ImageView cityBack = (ImageView) view.findViewById(R.id.iv_back_city);
TextView windowTitle = (TextView) view.findViewById(R.id.tv_title);
RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.rv);
liWindow.showRightPopupWindow(view);
}
//点击事件
@OnClick(R.id.iv_city_select)
public void onViewClicked() {//显示城市弹窗
showCityWindow();
}
接下来就是花里胡哨的操作了,首先我希望我的列表市动画展示出来的。 先创建动画文件,在模块中的anim文件 加下
item_animation_from_bottom.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500">
<translate
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:fromYDelta="50%p"
android:toYDelta="0"/>
<alpha
android:fromAlpha="0"
android:toAlpha="1"
android:interpolator="@android:anim/accelerate_decelerate_interpolator" />
</set>
item_animation_from_right.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500">
<translate
android:interpolator="@android:anim/decelerate_interpolator"
android:fromXDelta="100%p"
android:toXDelta="0"/>
<alpha
android:fromAlpha="0.5"
android:toAlpha="1"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"/>
</set>
layout_animation_from_bottom.xml
<?xml version="1.0" encoding="utf-8"?>
<layoutAnimation
xmlns:android="http://schemas.android.com/apk/res/android"
android:animation="@anim/item_animation_from_bottom"
android:delay="15%"
android:animationOrder="normal" />
layout_animation_slide_right.xml
<?xml version="1.0" encoding="utf-8"?>
<layoutAnimation
xmlns:android="http://schemas.android.com/apk/res/android"
android:animation="@anim/item_animation_from_right"
android:delay="10%"
android:animationOrder="normal"
/>
工具类 在模块的utils包下创建RecyclerViewAnimation
RecyclerViewAnimation.java 代码如下:
package com.llw.mvplibrary.utils;
import android.content.Context;
import android.view.animation.AnimationUtils;
import android.view.animation.LayoutAnimationController;
import androidx.recyclerview.widget.RecyclerView;
import com.llw.mvplibrary.R;
/**
* 动画RecycleView
*/
public class RecyclerViewAnimation {
//数据变化时显示动画 底部动画
public static void runLayoutAnimation(final RecyclerView recyclerView) {
final Context context = recyclerView.getContext();
final LayoutAnimationController controller =
AnimationUtils.loadLayoutAnimation(context, R.anim.layout_animation_from_bottom);
recyclerView.setLayoutAnimation(controller);
recyclerView.getAdapter().notifyDataSetChanged();
recyclerView.scheduleLayoutAnimation();
}
//数据变化时显示动画 右侧动画
public static void runLayoutAnimationRight(final RecyclerView recyclerView) {
final Context context = recyclerView.getContext();
final LayoutAnimationController controller =
AnimationUtils.loadLayoutAnimation(context, R.anim.layout_animation_slide_right);
recyclerView.setLayoutAnimation(controller);
recyclerView.getAdapter().notifyDataSetChanged();
recyclerView.scheduleLayoutAnimation();
}
}
MainActivity.java代码中
initCityData(recyclerView,areaBack,cityBack,windowTitle);//加载城市列表数据
/**
* 省市县数据渲染
* @param recyclerView 列表
* @param areaBack 区县返回
* @param cityBack 市返回
* @param windowTitle 窗口标题
*/
private void initCityData(RecyclerView recyclerView,ImageView areaBack,ImageView cityBack,TextView windowTitle) {
//初始化省数据 读取省数据并显示到列表中
try {
InputStream inputStream = getResources().getAssets().open("City.txt");//读取数据
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
StringBuffer stringBuffer = new StringBuffer();
String lines = bufferedReader.readLine();
while (lines != null) {
stringBuffer.append(lines);
lines = bufferedReader.readLine();
}
final JSONArray Data = new JSONArray(stringBuffer.toString());
//循环这个文件数组、获取数组中每个省对象的名字
for (int i = 0; i < Data.length(); i++) {
JSONObject provinceJsonObject = Data.getJSONObject(i);
String provinceName = provinceJsonObject.getString("name");
CityResponse response = new CityResponse();
response.setName(provinceName);
provinceList.add(response);
}
//定义省份显示适配器
provinceAdapter = new ProvinceAdapter(R.layout.item_city_list, provinceList);
LinearLayoutManager manager = new LinearLayoutManager(context);
recyclerView.setLayoutManager(manager);
recyclerView.setAdapter(provinceAdapter);
provinceAdapter.notifyDataSetChanged();
runLayoutAnimationRight(recyclerView);//动画展示
provinceAdapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {
@Override
public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
try {
//返回上一级数据
cityBack.setVisibility(View.VISIBLE);
cityBack.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
recyclerView.setAdapter(provinceAdapter);
provinceAdapter.notifyDataSetChanged();
cityBack.setVisibility(View.GONE);
windowTitle.setText("中国");
}
});
//根据当前位置的省份所在的数组位置、获取城市的数组
JSONObject provinceObject = Data.getJSONObject(position);
windowTitle.setText(provinceList.get(position).getName());
provinceTitle = provinceList.get(position).getName();
final JSONArray cityArray = provinceObject.getJSONArray("city");
//更新列表数据
if (citylist != null) {
citylist.clear();
}
for (int i = 0; i < cityArray.length(); i++) {
JSONObject cityObj = cityArray.getJSONObject(i);
String cityName = cityObj.getString("name");
CityResponse.CityBean response = new CityResponse.CityBean();
response.setName(cityName);
citylist.add(response);
}
cityAdapter = new CityAdapter(R.layout.item_city_list, citylist);
LinearLayoutManager manager1 = new LinearLayoutManager(context);
recyclerView.setLayoutManager(manager1);
recyclerView.setAdapter(cityAdapter);
cityAdapter.notifyDataSetChanged();
runLayoutAnimationRight(recyclerView);
cityAdapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {
@Override
public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
try {
//返回上一级数据
areaBack.setVisibility(View.VISIBLE);
areaBack.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
recyclerView.setAdapter(cityAdapter);
cityAdapter.notifyDataSetChanged();
areaBack.setVisibility(View.GONE);
windowTitle.setText(provinceTitle);
arealist.clear();
}
});
//根据当前城市数组位置 获取地区数据
windowTitle.setText(citylist.get(position).getName());
JSONObject cityJsonObj = cityArray.getJSONObject(position);
JSONArray areaJsonArray = cityJsonObj.getJSONArray("area");
if (arealist != null) {
arealist.clear();
}
if(list != null){
list.clear();
}
for (int i = 0; i < areaJsonArray.length(); i++) {
list.add(areaJsonArray.getString(i));
}
Log.i("list", list.toString());
for (int j = 0; j < list.size(); j++) {
CityResponse.CityBean.AreaBean response = new CityResponse.CityBean.AreaBean();
response.setName(list.get(j).toString());
arealist.add(response);
}
areaAdapter = new AreaAdapter(R.layout.item_city_list, arealist);
LinearLayoutManager manager2 = new LinearLayoutManager(context);
recyclerView.setLayoutManager(manager2);
recyclerView.setAdapter(areaAdapter);
areaAdapter.notifyDataSetChanged();
runLayoutAnimationRight(recyclerView);
areaAdapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {
@Override
public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
mPresent.todayWeather(context,arealist.get(position).getName());//今日天气
mPresent.weatherForecast(context, arealist.get(position).getName());//天气预报
mPresent.lifeStyle(context, arealist.get(position).getName());//生活指数
liWindow.closePopupWindow();
}
});
} catch (JSONException e) {
e.printStackTrace();
}
}
});
} catch (JSONException e) {
e.printStackTrace();
}
}
});
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}
运行一下:
可以看到城市已经切换好了,数据也拿到了。
