android 监听方法

只用一个监听器，通过不同的ID来判断是谁被按下

[java]

package tjj.testButton;

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.TextView;

public class TestbuttonActivity extends Activity {

private Button bt1;

private Button bt2;

private TextView tv;

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

tv = (TextView)findViewById(R.id.tv);

bt1 = (Button)findViewById(R.id.button1);

bt2 = (Button)findViewById(R.id.button2);

bt1.setOnClickListener(l);

bt2.setOnClickListener(l);

}

private OnClickListener l = new OnClickListener()

{

@Override

public void onClick(View v)

{

// TODO Auto-generated method stub

switch(v.getId())

{

case R.id.button1:

tv.setText("这是第一个");

break;

case R.id.button2:

tv.setText("这是第二个");

break;

}

}

};

}
