一、LayoutAnimation布局动画
用于为一个layout里面的控件，或者是一个ViewGroup里面的控件设置动画效果
在res-anim文件下新建一个动画xml文件
1 <?xml version="1.0" encoding="utf-8"?>
2 <set xmlns:android="http://schemas.android.com/apk/res/android"
3 android:interpolator="@android:anim/decelerate_interpolator" >
4
5 <scale
6 android:duration="1000"
7 android:fromXScale="0.1"
8 android:fromYScale="0.1"
9 android:pivotX="50%"
10 android:pivotY="50%"
11 android:toXScale="1.0"
12 android:toYScale="1.0" />
13 <alpha
14 android:duration="1000"
15 android:fromAlpha="0"
16 android:toAlpha="1.0" />
17 </set>list为列表
//布局动画控制器 LayoutAnimationController lac = new LayoutAnimationController(AnimationUtils.loadAnimation(this,R.anim.zoom_in)); //动画方式 lac.setOrder(LayoutAnimationController.ORDER_RANDOM); //加载布局动画 list.setLayoutAnimation(lac); //开始动画 list.startLayoutAnimation(); //为列表视图中选中的项添加响应事件
效果图：
全部代码：
1 package other;
2
3 import com.example.allcode.R;
4
5 import android.app.Activity;
6 import android.os.Bundle;
7 import android.view.View;
8 import android.view.animation.AnimationUtils;
9 import android.view.animation.LayoutAnimationController;
10 import android.widget.AdapterView;
11 import android.widget.AdapterView.OnItemClickListener;
12 import android.widget.ListView;
13 import android.widget.Toast;
14
15 public class Donghua_List extends Activity{
16 private ListView list;
17 @Override
18 protected void onCreate(Bundle savedInstanceState) {
19 // TODO Auto-generated method stub
20 super.onCreate(savedInstanceState);
21 setContentView(R.layout.donghua_layout);
22
23
24 list = (ListView) findViewById(R.id.listView1);
25 //布局动画控制器
26 LayoutAnimationController lac = new LayoutAnimationController(AnimationUtils.loadAnimation(this,R.anim.zoom_in));
27 //动画方式
28 lac.setOrder(LayoutAnimationController.ORDER_RANDOM);
29 //加载布局动画
30 list.setLayoutAnimation(lac);
31 //开始动画
32 list.startLayoutAnimation();
33 //为列表视图中选中的项添加响应事件
34 list.setOnItemClickListener(new OnItemClickListener() {
35
36 @Override
37 public void onItemClick(AdapterView<?> parent, View arg1, int pos,
38 long id) {
39 // TODO Auto-generated method stub
40 String result = parent.getItemAtPosition(pos).toString(); //获取选择项的值
41 Toast.makeText(Donghua_List.this, "点击了 "+result, Toast.LENGTH_SHORT).show();//输出选中项消息
42 }
43 });
44 }
45
46
47
48 } 1 <?xml version="1.0" encoding="utf-8"?>
2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3 android:layout_width="match_parent"
4 android:layout_height="match_parent"
5 android:orientation="vertical" >
6
7 <ListView
8 android:id="@+id/listView1"
9 android:entries="@array/list"
10
11 android:layout_width="match_parent"
12 android:layout_height="wrap_content" >
13 </ListView>
14
15 </LinearLayout>------------------------------------------------------------------------------------------------------------------
二、Drawable动画（帧动画）
即多张连续的动画顺序播放
核心类：AnimationDrawable
使用步骤：
1、在res下创建drawable文件夹创建资源文件 xx.xml （名字随便取）
有个属性 android:oneshot="false" 判断是否重复播放帧动画，默认false 表示循环播放，true表示只播放一次
1 <?xml version="1.0" encoding="utf-8"?>
2 <animation-list xmlns:android="http://schemas.android.com/apk/res/android"
3 android:oneshot="true"
4 >
5 <item android:drawable="@drawable/refresh_001" android:duration="200" />
6 <item android:drawable="@drawable/refresh_002" android:duration="200" />
7 <item android:drawable="@drawable/refresh_003" android:duration="200" />
8 <item android:drawable="@drawable/refresh_004" android:duration="200" />
9 <item android:drawable="@drawable/refresh_005" android:duration="200" />
10 <item android:drawable="@drawable/refresh_006" android:duration="200" />
11 <item android:drawable="@drawable/refresh_007" android:duration="200" />
12 <item android:drawable="@drawable/refresh_008" android:duration="200" />
13 <item android:drawable="@drawable/refresh_009" android:duration="200" />
14 <item android:drawable="@drawable/refresh_010" android:duration="200" />
15 <item android:drawable="@drawable/refresh_011" android:duration="200" />
16 <item android:drawable="@drawable/refresh_012" android:duration="200" />
17 <item android:drawable="@drawable/refresh_013" android:duration="200" />
18 <item android:drawable="@drawable/refresh_014" android:duration="200" />
19 <item android:drawable="@drawable/refresh_015" android:duration="200" />
20 <item android:drawable="@drawable/refresh_016" android:duration="200" />
21 <item android:drawable="@drawable/refresh_017" android:duration="200" />
22 <item android:drawable="@drawable/refresh_018" android:duration="200" />
23 <item android:drawable="@drawable/refresh_019" android:duration="200" />
24 <item android:drawable="@drawable/refresh_020" android:duration="200" />
25 <item android:drawable="@drawable/refresh_021" android:duration="200" />
26 <item android:drawable="@drawable/refresh_022" android:duration="200" />
27 <item android:drawable="@drawable/refresh_023" android:duration="200" />
28 <item android:drawable="@drawable/refresh_024" android:duration="200" />
29 <item android:drawable="@drawable/refresh_025" android:duration="200" />
30 <item android:drawable="@drawable/refresh_026" android:duration="200" />
31 <item android:drawable="@drawable/refresh_027" android:duration="200" />
32 <item android:drawable="@drawable/refresh_028" android:duration="200" />
33 <item android:drawable="@drawable/refresh_029" android:duration="200" />
34 <item android:drawable="@drawable/refresh_030" android:duration="200" />
35 <item android:drawable="@drawable/refresh_031" android:duration="200" />
36 <item android:drawable="@drawable/refresh_032" android:duration="200" />
37 <item android:drawable="@drawable/refresh_033" android:duration="200" />
38 <item android:drawable="@drawable/refresh_034" android:duration="200" />
39 <item android:drawable="@drawable/refresh_035" android:duration="200" />
40 <item android:drawable="@drawable/refresh_036" android:duration="200" />
41 <item android:drawable="@drawable/refresh_037" android:duration="200" />
42 <item android:drawable="@drawable/refresh_038" android:duration="200" />
43 <item android:drawable="@drawable/refresh_039" android:duration="200" />
44 <item android:drawable="@drawable/refresh_040" android:duration="200" />
45 <item android:drawable="@drawable/refresh_041" android:duration="200" />
46 <item android:drawable="@drawable/refresh_042" android:duration="200" />
47 <item android:drawable="@drawable/refresh_043" android:duration="200" />
48 <item android:drawable="@drawable/refresh_044" android:duration="200" />
49 <item android:drawable="@drawable/refresh_045" android:duration="200" />
50 <item android:drawable="@drawable/refresh_046" android:duration="200" />
51 <item android:drawable="@drawable/refresh_047" android:duration="200" />
52 <item android:drawable="@drawable/refresh_048" android:duration="200" />

55 </animation-list>2、布局文件
1 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
2 xmlns:tools="http://schemas.android.com/tools"
3 android:layout_width="match_parent"
4 android:layout_height="match_parent"
5 android:paddingBottom="@dimen/activity_vertical_margin"
6 android:paddingLeft="@dimen/activity_horizontal_margin"
7 android:paddingRight="@dimen/activity_horizontal_margin"
8 android:paddingTop="@dimen/activity_vertical_margin"
9 tools:context=".MainActivity" >
10
11 <ImageView
12 android:layout_width="wrap_content"
13 android:layout_height="wrap_content"
14 android:id="@+id/imageView"
15 android:background="@drawable/refresh_001"
16
17 />
18
19 </RelativeLayout>3、使用AnimationDrawable 类
（1）找到要显示动画的ImageView控件
imageView = (ImageView) findViewById(R.id.imageView);（2）给图片控件设置资源
imageView.setBackgroundResource(R.drawable.waiting_anim); //将帧动画资源文件作为View控件背景（3）获取AnimationDrawable 类对象
AnimationDrawable rocketAnimation = (AnimationDrawable) imageView.getBackground(); //获取背景并强转成为帧动画对象（4）启动动画
rocketAnimation.start();效果图：
