button在底部的多个view切换<实例二3D切换>
建议在看实例二之前参看一下实例1。
1. 镶嵌View的主ActivityGroup
package com.isomobile.widgets;
import android.app.ActivityGroup;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

}

final Button[] btns = mBtns;
for (int i = 0; i < btns.length; i++) {
btns[i] = (Button) findViewById(sResIds[i]);
btns[i].setOnClickListener(this);
}
//第一次启动时，默认跳转到第一个activity
mCurView[0] = getLocalActivityManager().startActivity(

onRotateAnimation(getCurButtonIndex(id));
}

}
public void onRotateAnimation(int index) {

}
private class AnimListener implements Animation.AnimationListener {

//可以设置buttons的背景或者状态(是否可点击等)
}

}

}
}
}
2. Rotate3d.class:

}

}
}
3. Animation3d.class:
package com.isomobile.widgets;
