                android:text="Button Two" />
        </LinearLayout>
    </LinearLayout>

</LinearLayout>


2. Inflate the view

private PopupWindow POPUP_WINDOW_SCORE = null; 
private void ShowPopup(string message)
{
	DisplayMetrics displayMetrics = this.getResources().getDisplayMetrics();
	int width = displayMetrics.widthPixels;
	int height = displayMetrics.heightPixels;
	
	// Inflate the popup_layout.xml	
	LayoutInflater layoutInflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
	View layout = layoutInflater.inflate(R.layout.layout_popup, null);

	// Creating the PopupWindow
	POPUP_WINDOW_SCORE = new PopupWindow(this);
	POPUP_WINDOW_SCORE.setContentView(layout);
	POPUP_WINDOW_SCORE.setWidth(width);
	POPUP_WINDOW_SCORE.setHeight(height);
	POPUP_WINDOW_SCORE.setFocusable(true);	

	// prevent clickable background
	POPUP_WINDOW_SCORE.setBackgroundDrawable(null);	
	
	POPUP_WINDOW_SCORE.showAtLocation(layout, Gravity.CENTER, 1, 1);
	
	TextView txtMessage = (TextView) layout.findViewById(R.id.layout_popup_txtMessage);
	txtMessage.setText(message);

	// Getting a reference to button one and do something
	Button butOne = (Button) layout.findViewById(R.id.layout_popup_butOne);
	butOne.setOnClickListener(new OnClickListener()
	{
		@Override
		public void onClick(View v)
		{
			//Do Something
			
			//Close Window
			POPUP_WINDOW_SCORE.dismiss();
		}
	});
	
	// Getting a reference to button two and do something
	Button butTwo = (Button) layout.findViewById(R.id.layout_popup_butTwo);
	butTwo.setOnClickListener(new OnClickListener()
	{
		@Override
		public void onClick(View v)
		{
			//Do Something
			
			//Close Window
			POPUP_WINDOW_SCORE.dismiss();
		}
	});
