Question

在单个活动屏幕上的我的应用程序中，我想请求以下两个窗口功能：

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); 
        requestWindowFeature(Window.FEATURE_LEFT_ICON);

两者都在一次添加一个时工作，但是当我将它们加在一起时它们不起作用。

请建议我们如何在android中完成它？

修改我的活动代码

@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
}

logcat的

Answer 1

您尝试制作requestWindowFeature() call before you call setContentView()?
