自定義dialog：

 1 private void customDialogDemo() {
 2         final AlertDialog dlg = new AlertDialog.Builder(this).create();
 3         dlg.show();
 4         Window window = dlg.getWindow();
 5         window.setContentView(R.layout.diylayout);
 6         ImageButton ok = (ImageButton) window.findViewById(R.id.btnok);
 7         ok.setOnClickListener(new View.OnClickListener() {
 8 
 9             @Override
10             public void onClick(View v) {
11                 Toast.makeText(getApplicationContext(), "關閉了",
12                         Toast.LENGTH_SHORT).show();
