实现两个Button，一个TextView的点击

方法一：用implements onClickListener实现

package com.listen;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class EventListen1 extends Activity implements OnClickListener {//step2实现监听
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        //step1,获取Button的id，设置监听
        //获取button01的id，并且设置监听
        Button button01 = (Button)findViewById(R.id.button01);
        button01.setOnClickListener(this);
        //获取button02的id，并且设置监听，与button01各自监听各自的
        Button button02 = (Button)findViewById(R.id.button02);
        button02.setOnClickListener(this);
         //获取可点击的textview的id，并且设置监听，与button01，02各自监听各自的，前面不用声明了
        TextView textview = (TextView)findViewById(R.id.textview);
        textview.setOnClickListener(this);
    }
//step3,添加onClick方法，当监听多个view的时候，用if判断是监听哪个view
    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        if(v.getId()==(R.id.textview)){
            Log.v("click..", "textview");
        }
        if(v.getId()==(R.id.button01)){
            Log.v("click..", "button01");
        }
        if(v.getId()==(R.id.button02)){
            Log.v("click..", "button02");
        }
    }
}

//xml代码如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:id="@+id/textview"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
    <Button
    android:id="@+id/button01"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="点1实现监听"
    />
      <Button
       android:id="@+id/button02"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="点2实现监听"
    />
</LinearLayout>

方法二：在xml代码中设置属性，onClick,OnClickButton实现

java代码如下：

package com.listen;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class EventListen1 extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
    }

    public void onClickButton(View v) {
        // TODO Auto-generated method stub
        if(v.getId()==(R.id.textview)){
            Log.v("click..", "textview");
        }
        if(v.getId()==(R.id.button01)){
            Log.v("click..", "button01");
        }
        if(v.getId()==(R.id.button02)){
            Log.v("click..", "button02");
        }
    }
}

xml如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:id="@+id/textview"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:onClick="onClickButton"
    android:clickable="true" 
    android:text="@string/hello"
    />
    <Button
    android:id="@+id/button01"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:onClick="onClickButton"
    android:text="点1实现监听"
    />
      <Button
       android:id="@+id/button02"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:onClick="onClickButton"
    android:text="点2实现监听"
    />
</LinearLayout>

实现结果同上。
