来电监听

在main.xml中：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:background="#00ff66">

</LinearLayout>

在PhoneBroadcastReceiver.java中：

package com.li.phone;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

public class PhoneBroadcastReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

context.startService(new Intent(context, PhoneService.class));

}

}

在PhoneService.java中：

package com.li.phone;

import java.text.SimpleDateFormat;

import java.util.Date;

import android.app.Service;

import android.content.Context;

import android.content.Intent;

import android.os.IBinder;

import android.telephony.PhoneStateListener;

import android.telephony.TelephonyManager;

public class PhoneService extends Service {

private TelephonyManager telephony = null;

@Override

public void onCreate() { // 服务创建的时候操作

super.onCreate();

this.telephony = (TelephonyManager) super

.getSystemService(Context.TELEPHONY_SERVICE);

this.telephony.listen(new PhoneStateListenerImpl(),

PhoneStateListener.LISTEN_CALL_STATE); // 设置监听操作

}

private class PhoneStateListenerImpl extends PhoneStateListener {

@Override

public void onCallStateChanged(int state, String incomingNumber) {

switch (state) {

case TelephonyManager.CALL_STATE_IDLE: // 挂断电话

break;

case TelephonyManager.CALL_STATE_RINGING: // 领音响起

System.out.println("拨入电话号码："

+ incomingNumber

+ "，拨入时间："

+ new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")

.format(new Date()));

break;

case TelephonyManager.CALL_STATE_OFFHOOK: // 接听电话

break;

}

}

}

@Override

public IBinder onBind(Intent intent) {

return null;

}

}

在MyPhoneDemo.java中：

package com.li.phone;

import android.app.Activity;

import android.os.Bundle;

public class MyPhoneDemo extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

}

}

修改AndroidManifest.xml：
