创建android逐帧动画的两种方式

1.设置背景方式

a.在res创建一个anim文件夹，该文件夹下创建animation_list.xml文件

<?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文件

<?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代码

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();
	}

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

	}

2.设置SRC方式

a.在res创建一个anim文件夹，该文件夹下创建animation_list.xml文件

<?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文件

<?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文件

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);
	}

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

	}
