我在OnCreate中有以下内容
requestWindowFeature(Window.FEATURE_NO_TITLE);
简历是:
@Override
public void onResume(){
onCreate(savedInstanceState);
super.onResume();
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.savedInstanceState = savedInstanceState;
requestWindowFeature(Window.FEATURE_NO_TITLE);
context = this;
ps = PuzzleState.getInstance();
setContentView(R.layout.activity_pack_list);
}
它会在活动恢复时抛出异常:必须在添加内容之前调用rewuestFeature。怎么了?

您需要在requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView
之前致电onCreate

如果在onCreate()方法之后设置了 requestWindowFeature(Window.FEATURE_NO_TITLE); ,则必须将其删除并设置
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.gallery_item);
}

private static boolean first = true;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.savedInstanceState = savedInstanceState;
if(first){
requestWindowFeature(Window.FEATURE_NO_TITLE);
first = false;
}
context = this;
ps = PuzzleState.getInstance();
setContentView(R.layout.activity_pack_list);
}
