帧动画

1、帧动画文件实现

1)在res目录下新建drawable目录,把动画图片放进去，并实现一个xml文件,例如:girl_list.xml

1 <?xml version="1.0" encoding="utf-8"?>
2 <animation-list xmlns:android="http://schemas.android.com/apk/res/android"  android:oneshot="false">
3      <item android:drawable="@drawable/a1" android:duration="100" />
4      <item android:drawable="@drawable/a2" android:duration="100" />
5      <item android:drawable="@drawable/a3" android:duration="100" />
6      <item android:drawable="@drawable/a4" android:duration="100" />
7      <item android:drawable="@drawable/a5" android:duration="100" />
8 </animation-list>

2、视图

 1 <LinearLayout 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:orientation="vertical"
 6     tools:context=".MainActivity" >
 7 
 8     <ImageView
 9         android:id="@+id/iv"
10         android:layout_width="wrap_content"
11         android:layout_height="0dip"
12         android:layout_weight="100"
13         android:background="@drawable/a1"
14          />
15     <Button 
16         
17         android:layout_width="wrap_content"
18         android:layout_height="wrap_content"
19         android:onClick="click"
20         android:text="播放"
21         />
22 
23 </LinearLayout>

3、java代码

 1 package com.example.myframe;
 2 
 3 import android.os.Bundle;
 4 import android.app.Activity;
 5 import android.graphics.drawable.AnimationDrawable;
 6 import android.view.Menu;
 7 import android.view.View;
 8 import android.widget.ImageView;
 9 
10 public class MainActivity extends Activity {
11     private AnimationDrawable rocketAnimation;
12     private ImageView iv;
13     @Override
14     protected void onCreate(Bundle savedInstanceState) {
15         super.onCreate(savedInstanceState);
16         setContentView(R.layout.activity_main);
17         iv = (ImageView) findViewById(R.id.iv);
18         //设置背景资源
19         iv.setBackgroundResource(R.drawable.girl_list);
20         rocketAnimation = (AnimationDrawable) iv.getBackground();//这个是异步方法，所以最好不要马上start方法
21 
22     }
23     
24     public void click(View view){
25         rocketAnimation.start();
26     }
27 
28 }
