android之动画popowindows
废话不多说，先看效果图：
这是主Activity代码：
public class RollActivity extends Activity {
private View view;
private Button btn;
private PopupWindow mPopupWindow;
private View[] btns;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// LinearLayout layout=(LinearLayout) view.findViewById(R.id.layout_main);
// //设置背景图片旋转180
// Bitmap mBitmap=setRotate(R.drawable.bg_kuang);
// BitmapDrawable drawable=new BitmapDrawable(mBitmap);
// layout.setBackgroundDrawable(drawable);
btn=(Button) this.findViewById(R.id.btn);
btn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
showPopupWindow(btn);
}
});
initPopupWindow(R.layout.popwindow);
}
private void initPopupWindow(int resId){
LayoutInflater mLayoutInflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
view = mLayoutInflater.inflate(resId, null);
mPopupWindow = new PopupWindow(view, 400,LayoutParams.WRAP_CONTENT);
// mPopupWindow.setBackgroundDrawable(new BitmapDrawable());//必须设置background才能消失
mPopupWindow.setBackgroundDrawable(getResources().getDrawable(R.drawable.bg_frame));
mPopupWindow.setOutsideTouchable(true);
//自定义动画
// mPopupWindow.setAnimationStyle(R.style.PopupAnimation);
//使用系统动画
mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);
mPopupWindow.update();
mPopupWindow.setTouchable(true);
mPopupWindow.setFocusable(true);
btns=new View[3];
btns[0]=view.findViewById(R.id.btn_0);
btns[1]=view.findViewById(R.id.btn_1);
btns[2]=view.findViewById(R.id.btn_2);
btns[0].setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//doSomething
}
});
btns[1].setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//doSomething
}
});
btns[2].setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//doSomething
}
});
}
private void showPopupWindow(View view) {
if(!mPopupWindow.isShowing()){
// mPopupWindow.showAsDropDown(view,0,0);
mPopupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
}
}
public Bitmap setRotate(int resId) {
Matrix mFgMatrix = new Matrix();
Bitmap mFgBitmap = BitmapFactory.decodeResource(getResources(), resId);
mFgMatrix.setRotate(180f);
return mFgBitmap=Bitmap.createBitmap(mFgBitmap, 0, 0,
mFgBitmap.getWidth(), mFgBitmap.getHeight(), mFgMatrix, true);
}
} PopupWindow的布局popwindow.xml 注意3个LinearLayout里必须设置clickable和background，这样当点击上去的时候才会有点击效果。 android:clickable="true" android:background="@drawable/state_btn_pressed"
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:id="@+id/layout_main"
>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal"
android:clickable="true"
android:background="@drawable/state_btn_pressed"
android:layout_weight="1"
android:id="@+id/btn_0"
>
<ImageView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitCenter"
android:src="@drawable/ic_call"
>
</ImageView>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:textSize="18px"
android:text="电话">
</TextView>
</LinearLayout>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal"
android:clickable="true"
android:background="@drawable/state_btn_pressed"
android:layout_weight="1"
android:id="@+id/btn_1"
>
<ImageView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitCenter"
android:src="@drawable/ic_home"
>
</ImageView>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000"
android:textSize="18px"
android:text="空间">

</LinearLayout>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal"
android:clickable="true"
android:background="@drawable/state_btn_pressed"
android:layout_weight="1"
android:id="@+id/btn_2"

android:layout_height="wrap_content"
android:textColor="#000"
android:textSize="18px"
android:text="短信"
>
</TextView>
</LinearLayout>
</LinearLayout> state_btn_pressed.xml，点击的效果：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="@drawable/bg_btn_pressed"
android:padding="0dp"/>
</selector> Android 模仿迅雷的 PopupWindow 出现/消失动画 出现：
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale android:fromXScale="0.6" android:toXScale="1.1"
android:fromYScale="0.6" android:toYScale="1.1" android:pivotX="50%"
android:pivotY="50%" android:duration="200" />
<scale android:fromXScale="1.0" android:toXScale="0.91"
android:fromYScale="1.0" android:toYScale="0.91" android:pivotX="50%"
android:pivotY="50%" android:duration="400" android:delay="200" />
<alpha android:interpolator="@android:anim/linear_interpolator"
android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="400" />
</set> 消失：
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale android:fromXScale="1.0" android:toXScale="1.25"
android:fromYScale="1.0" android:toYScale="1.25" android:pivotX="50%"
android:pivotY="50%" android:duration="200" />
<scale android:fromXScale="1.0" android:toXScale="0.48"
android:fromYScale="1.0" android:toYScale="0.48" android:pivotX="50%"
android:pivotY="50%" android:duration="400" android:delay="200" />
<alpha android:interpolator="@android:anim/linear_interpolator"
android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="400" />
</set> 最后用下面的 XML 封装：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="PopupAnimation" parent="android:Animation"
mce_bogus="1">
<item name="android:windowEnterAnimation">@anim/anim_dialog_show</item>
<item name="android:windowExitAnimation">@anim/anim_dialog_hide</item>
</style>
