android - fragment 中的 OnPostCreate

Question

我在 onPostCreate 的 Activity 中使用了 TextWatcher，但现在我已经将它变成了 Fragment。

fragment 中的这个等价物是什么？

  @Override
protected void onPostCreate(Bundle savedInstanceState) {
    mSearchView.addTextChangedListener(filterTextWatcher);
    super.onPostCreate(savedInstanceState);
}

Answer 1

查看 fragment 生命周期。等到 Fragment 附加到 Activity

您可以在 onActivityCreated 中完成您的工作。

要获取 Context，请使用 getActivity()

protected void onPostCreate (Bundle savedInstanceState)

Added in API level 1

Called when Activity start-up is complete (after onStart() and onRestoreInstanceState(Bundle) have been called). Applications will generally not implement this method; it is intended for system classes to do final initialization after application code has run.

Derived classes must call through to the super class's implementation of this method. If they do not, an exception will be thrown.

Parameters savedInstanceState If the Activity is being re-initialized after previously being shut down then this Bundle contains the data it most recently supplied in onSaveInstanceState(Bundle). Note: Otherwise it is null.
