Question

I’ve got this dialog (I’m simplifying my use case):

class EditShoppingListDialog extends AlertDialog {

    public EditShoppingListDialog(Context context) {
        super(context/*, R.style.AppCustomDialog*/);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_addshoppinglist);
        setTitle("Mike Testing");
    }
}

I create and use this subclassed AlertDialog outside of the OnCreateDialog method (in the onContextItemSelected of my Activity) like this:

AlertDialog dialog = new EditShoppingListDialog(this);
dialog.show();

Now, I’ve been working with this code base for over a month now and never saw any problems, which lead me to wonder why they recommend using AlertDialog.Builder for creating custom dialogs also.

When I deployed my app to a real device, I immediately started to see problems. The most blocking of them is that I cannot get the soft keyboard (IME?) to show up even when I click on an EditText field in the AlertDialog.

Here’s the best part; If I say:

class EditShoppingListDialog extends Dialog {
    ...
}

The IME appears appears automatically if I click in an EditText in the dialog. I found this thread but the accepted solution does not work with AlertDialog.

However, I found doing this on the OnCreate of my derived AlertDialog helps show the IME, but it goes behind the dialog and I can’t interact with it:

InputMethodManager imm = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT,0);

I’m really sorry for the lost post, but I’ve spent more than 5 hours on this and would be very grateful for some help. The reason I insist on extending an AlertDialog is because I need a dialog without a title bar and it says in the Android Dialog documentation that I cannot have a Dialog without a title bar.

Answer 1

It is easy to set a dialog without title.
create a style as below,

 <style name="no_title_dialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
</style>

initial dialog with

Dialog notitleDialog = new Dialog(this, R.style.no_title_dialog);

the dialog should appear with no title
