How To Remove "ok" Button From Dialog Fragment In Android

I'm trying to remove the OK button completely so that an item is automatically clicked when selected. I noticed that this is Android's preferred way of doing it. I don't need a 'ca

Solution 1:

I'm not sure if this is the Android recommended way of doing this but I finally figured out a way of achieving the exact behavior I want.

public class SingleChoiceClass extends 
DialogFragment {

final CharSequence[] items = {"b1", "b2", "b3", "b4"};
String selection;
@NonNull
@Override

public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
final MainActivity activity = (MainActivity) getActivity();

builder.setTitle("Choose")
    .setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface arg0, int arg1) {
switch (arg1){
    case 0:
        selection = (String) items[arg1];
        Toast.makeText(getActivity(), "" + selection,Toast.LENGTH_SHORT).show();
        // Do your magic
        dismiss();
        break;
    case 1:
        selection = (String) items[arg1];
        Toast.makeText(getActivity(), "" + selection,Toast.LENGTH_SHORT).show();
        // Do your magic
        dismiss();
        break;
    case 2:
        selection = (String) items[arg1];
        Toast.makeText(getActivity(), "" + selection,Toast.LENGTH_SHORT).show();
        // Do your magic
        dismiss();
        break;
    case 3:
        selection = (String) items[arg1];
        Toast.makeText(getActivity(), "" + selection,Toast.LENGTH_SHORT).show();
        // Do your magic
        dismiss();
        break;
        }
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {

        //Exit
        activity.finish(); //Or find a way to relaunch Dialog
    }
});
return builder.create();
 }
}
