error: requestFeature() must be called before adding content - Still won't work

Question

I know that similar questions have been asked in the past but I can\'t seem to get this working at all even with the suggestions.

I get the above abend on the \"show

Answer 1

Try calling

.setTitle(R.string.uploadedScoreTitle);

before

.setContentView(R.layout.submitscoreprompt);

Answer 2

I experienced the same problem. I found that the problem only occurs if I do both of the following things:

• I don't use activity managed dialogs (activity.showDialog() -> activity.onCreateDialog()/onPrepareDialog())

• I do dialog.findViewById() (and this is indeed the line difference between success or the requestFeature exception!).

final Builder dialogBuilder = new AlertDialog.Builder(activity);
b.setView(rootView);
b.setIcon(android.R.drawable.ic_dialog_info);
b.setTitle(R.string.message_of_the_day_title);
b.setCancelable(false);
dialog = b.createDialog();
dialog.findViewById(R.id.myid); // this is the problem

The dialog.findViewById() causes the problem because it calls

dialog.getWindow().getDecorView()

and the method javadoc of getDecorView() says:

Note that calling this function for the first time "locks in" various window characteristics as described in {@link #setContentView(View, android.view.ViewGroup.LayoutParams)}.

Isn't that nice, findViewById() has a side effect which causes seemingly correct applications to crash. Why there's a difference between Activity managed dialogs and normal dialogs I do not know, but I guess getDecorView() does some magic for Activity managed dialogs.

I did the above because I moved from using Activity managed dialogs to handling dialogs myself.

The solution for me is to manipulate the rootView, using rootView.findViewById(), instead of manipulating the dialog.

Answer 3

Substitude the following line:

whatToUploadDialog.setContentView(R.layout.submitscoreprompt);

with:

whatToUploadDialog.setView(R.layout.submitscoreprompt);
