自定义的dialog，解决键盘不同层，不能输入的问题

纯代码，无讲解，一看就会明白的：
 1     final AlertDialog dlg=new AlertDialog.Builder(this).create();
 2     View view = LayoutInflater.from(getApplicationContext()).inflate(R.layout.user_tag_personal, null);
 3     dlg.setView(view);
 4     dlg.show();
 5     Window window=dlg.getWindow();
 6     window.setContentView(R.layout.user_tag_personal);
 7                 
 8     RelativeLayout userTagLayout=(RelativeLayout) view.findViewById(R.id.userTagLayout);
 9                                                 
10     final EditText et=(EditText) window.findViewById(R.id.user_tag);
11                 
12     ImageButton close=(ImageButton) window.findViewById(R.id.close_drop_out);
13     close.setOnClickListener(new OnClickListener() {
14                     
15         @Override
16         public void onClick(View arg0) {
17             // TODO Auto-generated method stub
18             dlg.dismiss();
19         }
20     });
21     TextView yes_drop_out=(TextView) window.findViewById(R.id.yes_drop_out);
