Dialog problem: requestFeature() must be called before adding content

Question

I\'m creating a custom dialog containing an EditText so that I can get text data from the user:

final EditText newKey = (EditText) findViewById(R.id.dialog_r         


        

Answer 1

I also had this error message when using a DialogFragment.

My problem was solved when in the onCreateDialog(Bundle savedInstanceState) I changed the dialog that I returned

from

android.appAlertDialog

to

androidx.appcompat.app.AlertDialog

(or if you haven't migrate to AndroidX, then android.support.v7.app.AlertDialog)
