Frame-By-Frame Animations的使用方法

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
	android:oneshot="false">
	<item android:drawable="@drawable/nv1" android:duration="500" />
	<item android:drawable="@drawable/nv2" android:duration="500" />
	<item android:drawable="@drawable/nv3" android:duration="500" />
	<item android:drawable="@drawable/nv4" android:duration="500" />
</animation-list>

首先是建在res的drawable目录下面建一个 anmi_nv.xml文件，再写上上面的配置。

下面是MainActivity：

package mars.animations05;

import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;

public class MainActivity extends Activity {
	private Button button = null;
	private ImageView imageView = null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        imageView = (ImageView)findViewById(R.id.imageViewId);
        button = (Button)findViewById(R.id.buttonId);
        button.setOnClickListener(new ButtonListener());
    }
    
    private class ButtonListener implements OnClickListener{

		public void onClick(View v) {
			imageView.setBackgroundResource(R.drawable.anim_nv);
			AnimationDrawable animationDrawable = (AnimationDrawable)imageView.getBackground();
			animationDrawable.start();
		}
    	
    }
}

main.xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent">

	<Button android:id="@+id/buttonId" android:layout_width="fill_parent"
		android:layout_height="wrap_content" android:layout_alignParentBottom="true"
		android:text="测试动画效果" />

		
	<LinearLayout android:orientation="vertical"
		android:layout_width="fill_parent" android:layout_height="fill_parent">

		<ImageView android:id="@+id/imageViewId"
			android:layout_width="wrap_content" android:layout_height="wrap_content"
			android:layout_centerInParent="true" android:layout_marginTop="100dip"
			/>
	</LinearLayout>
</RelativeLayout>
