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>
