How can I get reference on TextView from XML layout in AlertDialog?
android, android-alertdialog
Solution
You almost had it there in your original code. You saved the View returned by `LayoutInflater`, so that's the one you should use when calling `findViewById()` so it must be `dialogLayout.findViewById(...)`. I was having the same issue myself and works like charm now.
Problem
I have a curious problem with getting reference on TextView, SeekBar and other widgets. My AlertDialog looks like this: ``` public class LineDialog extends AlertDialog { private static SeekBar seekBar1, seekBar2, seekBar3; private static TextView textView1, textview2, textView3; protected LineDialog(final Context context, final DrawView drawView) { super(context); LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View dialogLayout = inflater.inflate(R.layout.line_dialog, null); setView(dialogLayout); setTitle("Line properties"); textView1 = (TextView) findViewById(R.id.textView1); // TODO Code crash here :( setButton("Ok", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { seekBar1 = (SeekBar) findViewById(R.id.seek1); // some other code... } }); } ``` When I want get reference in Line where is ``` textView1 = (TextView) findViewById(R.id.textView1); ``` Logcat send me an Error ``` requestFeature() must be called before adding content ``` But when I get reference in onClick() method in LineDiealog(AlertDialog) everything works fine. Unfortunately this is too late, because I need this reference before LineDialog.show() is called...
