EditText SetText Not Displaying On A Dialog Fragment

I'm kinda new to Android app development, and don't know how to debug this. So I'm trying to do EditText.setText on a DialogFragment. It prints out the right string on the log, but

Solution 1:

You don't use layout view for Dialog so that you can't see text on EditText. Please change as here:

 AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(getActivity());
    alertDialogBuilder.setTitle("Edit to-do list");

    final View layout = View.inflate(MainActivity.getAppContext(), R.layout.custom_dialog, null);
    alertDialogBuilder.setView(layout );

Solution 2:

Try this:

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(getActivity());

LayoutInflater inflater = getActivity().getLayoutInflater();
View customView = inflater.inflate(R.layout.custom_dialog, null);

alertDialogBuilder.setView(customView);
alertDialogBuilder.setTitle("Edit to-do list");

final EditText mEditText = (EditText) customView.findViewById(R.id.EditDesc);
String desc = getArguments().getString("desc");
mEditText.setText(desc);

alertDialogBuilder.setPositiveButton("OK",  new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // on success
        EditTodoFragment.EditTodoFragmentListener listener = (EditTodoFragment.EditTodoFragmentListener)getActivity();
        listener.onFinishEditDialog(mEditText.getText().toString());
    }
});
alertDialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        dialog.dismiss();
    }
});

return alertDialogBuilder.create();
