Go back to a Fragment from an Activity onBackpress

Question

I Tried the following code to move from a Fragment extends Fragment to an Activity extends activity.

 Intent mIntent = new Intent(getActivity(), UserProfile.class);
            Bundle bundle = new Bundle();
            bundle.putBoolean(Constant.isFromChatScreen, false);
            mIntent.putExtras(bundle);
            startActivity(mIntent);

In BaseActivity.java I have Fragment A , Fragment B , Fragment C ..from Fragment A I moved to Userprofile.java now I want to move back to Fragment A onBackPressed How can I do that?

Answer 1

Check Google documentation for findFragmentByTag() here .

You can also use addToBackStack() while calling the fragment from FragmentTransaction

Answer 2

进行片段事务时，只需在提交前使用addToBackStack(null) ，然后按返回按钮即可返回片段。

Answer 3

Old question, but anyone looking for an answer to this can just do this:

@Override
public void onBackPressed() {
  finish();
}

finish() "closes" the current Activity and takes you back to the Fragment (Actually, it takes you back to the Activity hosting the Fragment)
