[android-beginners] Re: AlertDialog text input problem
This works for me for an EditText as well. But when I try the same
code for a Spinner I receive a NullPointerException. Both views are in
the same Layout and both views have got an id. Actually, it is exactly
the same code except the kind of the view. Any idea why I got this
exception?
Thanks

Hopefully this post will help others. I could not find a good example of
using AlertDialog for text input. The API Demos example does not show how
to return the text!
Thanks again Mark!

new AlertDialog.Builder(Peeps.this)
//.setIcon(R.drawable.alert_dialog_icon)

.setView(textEntryView)
.setPositiveButton(R.string.search_dialog_ok, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton) {
EditText et =
(EditText)findViewById(R.id.search_edit); // !!! apparently I am doing
this wrong!
I am assuming R.id.search_edit is a field in the textEntryView you
supplied to the builder.
In that case, try textEntryView.findViewById(R.id.search_edit).
