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>
