Why not use an AlertDialog if you have 3 or less buttons?

My AlertDialog looks like this:

My java code:

LayoutInflater inflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.add_filter, null);

AlertDialog alertDialog = new AlertDialog.Builder(this)
        .create();
alertDialog.setTitle("AlertDialog title");
alertDialog.setMessage("AlertDialog message");
alertDialog.setView(view);
alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK",
        new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog,
                    int which) {
                dialog.dismiss();
            }
        });
alertDialog.show();

My XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <Spinner
        android:id="@+id/spinner_filter"
        android:layout_width="wrap_content"
        android:spinnerMode="dropdown"
        android:layout_height="wrap_content"
        android:entries="@array/filter_array"
        android:prompt="@string/filter_prompt" />

</LinearLayout>

Simple yet does what you need.
