在我的单个 Activity 屏幕上的应用程序中，我想请求以下两个窗口功能:
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
requestWindowFeature(Window.FEATURE_LEFT_ICON);
一次添加一个时两者都在工作，但是当我将它们两个加在一起时它们都不起作用。
请建议我们如何在android中做到这一点？

我的 Activity 代码
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
Log.v("TAG", "After super.onCreate()");
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
Log.v("TAG", "after Window.FEATURE_INDETERMINATE_PROGRESS");
requestWindowFeature(Window.FEATURE_LEFT_ICON);
Log.v("TAG", "after Window.FEATURE_LEFT_ICON");
setContentView(R.layout.categotylist);
Log.v("TAG", "after setContentView");
lists = new ArrayList<String>();
\\some more code
}

最佳答案
你试着让你的requestWindowFeature() call before you call setContentView()?
