android - 如何对话框在外部触摸时保持打开状态

Question

我的屏幕上有对话框。当我触摸屏幕时对话框关闭。我希望对话框不应该在外部触摸时关闭。我的代码如下:-

public class Dialogue extends Activity{

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_dialogue);
        this.setFinishOnTouchOutside(false);
        displayDialogue();

    }
    private void displayDialogue(){
        final AlertDialog.Builder myDialogue = new AlertDialog.Builder(this);
        myDialogue.setMessage("Please check your voice input output settings.It should be ON" );
        TextView messageView = new TextView(this);
        messageView.setGravity(Gravity.CENTER);
        myDialogue.setView(messageView);
        myDialogue.setPositiveButton("OK",  new DialogInterface.OnClickListener()
        {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                Intent i = new Intent(Dialogue.this, MainActivity.class);
                startActivity(i);
                finish();
            }
        });

        AlertDialog dialog = myDialogue.create();
        dialog.show();
    }
