1     @Override2     protected void onCreate(Bundle savedInstanceState) {3         super.onCreate(savedInstanceState);4         setContentView(R.layout.activity_main);5     }6 7     public void doSomething(View view){8         Log.e("MainActivity","Clicked");9     }

点击button时 call doSomething();

 

如果有多个Button，则通过下面两种方式做出不同的响应：

1      7  8     14 15     
     

1     public void doSth1(View view){ 2         Log.e("MainActivity", "Clicked1"); 3     } 4  5     public void doSth2(View view){ 6  7         if(view.getId()==R.id.button2) 8             Log.e("MainActivity","Clicked2"); 9         if(view.getId()==R.id.button3)10             Log.e("MainActivity","Clicked3");11     }

如上，在doSth2()中通过view.getId()来获取不同的值，注意@+id/button3和R.id.button3是分别在xml和java中对同一个整数值的描述
