android各种控件的事件监听及举例

原帖地址：http://www.iteye.com/topic/1060815#

 

下面是各种常用控件的事件监听的使用

①EditText（编辑框）的事件监听---OnKeyListener

②RadioGroup、RadioButton（单选按钮）的事件监听---OnCheckedChangeListener

③CheckBox（多选按钮）的事件监听---OnCheckedChangeListener

④Spinner（下拉列表）的事件监听---OnItemSelectedListener

⑤Menu（菜单）的事件处理---onMenuItemSelected

⑥Dialog（对话框）的事件监听---DialogInterface.OnClickListener()

至于Button的事件监听，可以在上一篇博客中看到。

第一个例子：EditText的事件监听

  20.         /**

  23.          */  
  24.         edittext.setHint("请输入账号");  
  25.         //下面为EditText事件监听  
  26.         edittext.setOnKeyListener(new EditText.OnKeyListener()  
  27.         {  
  28.   
  29.             @Override  
  30.             public boolean onKey(View arg0, int arg1, KeyEvent arg2) {  
  31.                 //得到文字，显示在TextView中  
  32.                 mytext.setText("内容："+edittext.getText().toString());  
  33.                 return false;  
  34.             }  
  35.               
  36.         });  
  37.     }  
  38. }</span>
