Question

当我尝试通过帧和ImageView设置图像动画时，我遇到了异常。这是代码：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    ImageView rocketImage = (ImageView) findViewById(R.id.imageView1);
    rocketImage.setBackgroundResource(R.drawable.animation_sample);
    AnimationDrawable rocketAnimation = (AnimationDrawable) rocketImage.getBackground();
    rocketAnimation.run();
}

和我的animation_sample.xml

<frames id="anim_sample" oneshot="false">
  <frame drawable="@drawable/a1" duration="50" />
  <frame drawable="@drawable/a2" duration="50" />
  <frame drawable="@drawable/a3" duration="50" />  
  <frame drawable="@drawable/a4" duration="50" />
  <frame drawable="@drawable/a5" duration="50" />
</frames>

和main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <ImageView android:id="@+id/imageView1" android:src="@drawable/icon"
        android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView>
</LinearLayout>

我是否遗漏了任何内容（在manifest.xml或其他任何内容中）？

尝试使用此animation_sample.xml

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/anim_sample" android:oneshot="false">
  <item android:drawable="@drawable/a1" android:duration="50" />
  <item android:drawable="@drawable/a2" android:duration="50" />
  <item android:drawable="@drawable/a3" android:duration="50" />  
  <item android:drawable="@drawable/a4" android:duration="50" />
  <item android:drawable="@drawable/a5" android:duration="50" />
</animation-list>

抱歉，如果有一些错误，但我没有这里的eclipse和SDK
