在活动标题栏中显示加载图标

Question

如何在活动标题栏中显示加载图标？

Answer 1

@Override 
public void onCreate(Bundle icicle) { 
    super.onCreate(icicle); 
    requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); 
    setContentView(R.layout.your_layout); 
} 

然后......在任何你想要的：

// then, you can do this to show the icon 
setProgressBarIndeterminateVisibility(true); 
//or to hide it 
setProgressBarIndeterminateVisibility(false); 

确保setContentView前使用requestWindowFeature。
