Android DialogFragment onViewCreated 未调用

问题描述

我正在使用 android 兼容性库(v4 修订版 8).在自定义 DialogFragment 中，未调用 onViewCreated 覆盖的方法.例如.

I am using android compatibility library (v4 revision 8). In the custom DialogFragment the overrided method onViewCreated is not getting called.For eg.

public class MyDialogFragment extends DialogFragment{
    private String mMessage;
    public MyDialogFragment(String message) {
        mMessage = message;
    }

    @Override
    public Dialog onCreateDialog( Bundle savedInstanceState){
        super.onCreateDialog(savedInstanceState);
        Log.d("TAG", "onCreateDialog");
        setRetainInstance(true);
        //....do something
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        Log.d("TAG", "onViewCreated");
        //...do something
    }
}

onViewCreated 没有被记录.

onViewCreated is not getting logged.

推荐答案

好吧，onViewCreated 状态的文档在 onCreateView(LayoutInflater, ViewGroup, Bundle) 返回后立即调用".

Well, the docs for onViewCreated state "Called immediately after onCreateView(LayoutInflater, ViewGroup, Bundle) has returned".

DialogFragment 使用 onCreateDialog 而不是 onCreateView，因此不会触发 onViewCreated.(这应该是我的工作理论，我还没有深入研究 android 源代码来确认).

DialogFragment uses onCreateDialog and not onCreateView, so onViewCreated is not fired. (Would be my working theory, I haven't dived into the android source to confirm).
