建立android逐幀動畫的兩種方式

1.設定背景方式
a.在res建立一個anim檔案夾，該檔案夾下建立animation_list.xml檔案
[html]
<?xml version="1.0" encoding="utf-8"?> 
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" 
    android:oneshot="true" > 
 
    <item 
        android:drawable="@drawable/c1" 
        android:duration="200"/> 
    <item 
        android:drawable="@drawable/c2" 
        android:duration="200"/> 
    <item 
        android:drawable="@drawable/c3" 
        android:duration="200"/> 
    <item 
        android:drawable="@drawable/c4" 
        android:duration="200"/> 
    <item 
        android:drawable="@drawable/c5" 
        android:duration="200"/> 
    <item 
        android:drawable="@drawable/c6" 
        android:duration="200"/> 
 
</animation-list> 

b. layout檔案
[html]
<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 
 
    <ImageView 
        android:id="@+id/imageView1" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:layout_centerHorizontal="true" 
        android:paddingTop="50dp" > 
    </ImageView> 
 
    <Button 
        android:id="@+id/button2" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:layout_alignParentBottom="true" 
        android:text="Run"  
        android:onClick="run"> 
    </Button> 
 
</LinearLayout> 
c.java代碼
[java]
protected void onCreate(Bundle savedInstanceState) { 
        // TODO Auto-generated method stub 
        super.onCreate(savedInstanceState); 
        this.setContentView(R.layout.contextmenu); 
        imageView = (ImageView) findViewById(R.id.imageView1); 
        imageView.setBackgroundResource(R.anim.animation_list); 
        draw = (AnimationDrawable) imageView.getBackground(); 
//      draw = (AnimationDrawable) imageView.getDrawable(); 
    } 

[java]
public void run(View v) { 
        if (draw.isRunning()) { 
            draw.stop(); 
        } else { 
            draw.stop(); 
            draw.start(); 
        } 
 
    } 

 

2.設定SRC方式
a.在res建立一個anim檔案夾，該檔案夾下建立animation_list.xml檔案
[html]
<?xml version="1.0" encoding="utf-8"?> 
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" 
    android:oneshot="true" > 
 
    <item 
        android:drawable="@drawable/c1" 
        android:duration="200"/> 
    <item 
        android:drawable="@drawable/c2" 
        android:duration="200"/> 
    <item 
        android:drawable="@drawable/c3" 
        android:duration="200"/> 
    <item 
        android:drawable="@drawable/c4" 
        android:duration="200"/> 
    <item 
        android:drawable="@drawable/c5" 
        android:duration="200"/> 
    <item 
        android:drawable="@drawable/c6" 
        android:duration="200"/> 
 
</animation-list> 

b.layout檔案
[html]
<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 
 
    <ImageView 
        android:id="@+id/imageView1" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:layout_centerHorizontal="true" 
          android:src="@anim/animation_list" 
        android:paddingTop="50dp" > 
    </ImageView> 
 
    <Button 
        android:id="@+id/button2" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:layout_alignParentBottom="true" 
        android:text="Run"  
        android:onClick="run"> 
    </Button> 
 
</LinearLayout> 
c.layout檔案
[java]
protected void onCreate(Bundle savedInstanceState) { 
        // TODO Auto-generated method stub 
        super.onCreate(savedInstanceState); 
        this.setContentView(R.layout.contextmenu); 
        imageView = (ImageView) findViewById(R.id.imageView1); 
        imageView.setBackgroundResource(R.anim.animation_list); 
//      draw = (AnimationDrawable) imageView.getBackground(); 
        draw = (AnimationDrawable) imageView.getDrawable(); 
        registerForContextMenu(text); 
    } 

[java]
public void run(View v) { 
        if (draw.isRunning()) { 
            draw.stop(); 
        } else { 
            draw.stop(); 
            draw.start(); 
        } 
 
    }
