Can we have vertical buttons in an Android alert d

Question

By default, we get two or three buttons that are horizontally aligned in an alert dialog. Is it possible to have them vertically aligned within the alert dialog?

Answer 1

Sure, you can use Dialog.setContentView() to set the content of a dialog to be an arbitrary layout.

Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.yourLayoutId);
dialog.show();

Make yourself a layout file with a Vertical LinearLayout that has the buttons you want in it and call setContentView() on your dialog, passing the name of your layout file.

If you are deadset on AlertDialog you can do something similar with builder.setView()

LayoutInflater inflater = (LayoutInflater) 
        getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.yourLayoutId,
        (ViewGroup) findViewById(R.id.yourLayoutRoot));
AlertDialog.Builder builder = new AlertDialog.Builder(this)
.setView(layout);
AlertDialog alertDialog = builder.create();
alertDialog.show();

Answer 2

There has been a setItems() call which does this since API level 1. No reason to create a custom dialog unless you want to change the look and feel of the items.

CharSequence[] items =  {"Foo", "Bar", "FooBar"};
new AlertDialog.Builder(activity)
.setTitle("Choose a widget")
.setItems(items, new DialogInterface.OnClickListener()
{
     @Override
     public void onClick(DialogInterface dialog, int which)
     {
         switch(which)
         {
             case FOO:
             // foo case
             break;

             ....
         }
     }
}
.create().show();
