转载：AndroidChina>>Android Button监听的几种方法

1 一个Button控件对应一个监听

Button buttontestbuttontest = (Button)findViewById(R.id.button1);buttontest.setOnClickListener(new View.OnClickListener(){    @Override    public void onClick(View v){        //TODO Auto-generated method stub});

2 多个Button对应一个监听
方法一：

start = (Button)findViewById(R.id.button1);stop = (Button)findViewById(R.id.button2);start.setOnClickListener(mylistener);stop.setOnClickListener(mylistener);View.OnClickListener mylistener = new View.OnClickListener(){    @Override    public void onClick(View v){        switch(v.getId()){        case R.id.button1:            //what you want to do            break;                  case R.id.button2:            //what you want to do            break;                        default:                break;        }    }};

方法二：

public class MainActivity extends Activity implements View.OnClickListner{    //界面元素    private Button start;    private Button stop;    @Override    public void onCreate(Bundle savedInstanceState){        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        start = (Button)findViewById(R.id.button1);        stop = (Button)findViewById(R.id.button2);                start.setOnClickListener(this);        stop.setOnClickListener(this);    }    @Override    public void onClick(View v){        switch(v.getId()){             case R.id.button1:            //what you want to do            break;          case R.id.button2:            //what you want to do            break;           default:                //TODO                break;        }    }}

3 xml中绑定监听：

<Button    android:id = "@+id/button1"    android:layout_height = "wrap_content"    android:layout_weight = "wrap_content"    android:onClick = "mybuttonlistener"/>

对应JAVA代码

Button btn = (Button)findViewById(R.id.button1);public void mybuttonlistener(View target){    //TODO}

建议：不推荐使用第四种实现方式
