android 呼入电话的监听（来电监听）

需要权限：

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

方式一：通过广播接收来电

定义来电广播接收类。

package com.zhouzijing.android.demo;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.telephony.TelephonyManager;

import android.util.Log;

public class BroadcastReceiverMgr extends BroadcastReceiver {

private final String TAG = MyBroadcastReceiver.TAG;

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

Log.i(TAG, "[Broadcast]"+action);

//呼入电话

if(action.equals(MyBroadcastReceiver.B_PHONE_STATE)){

Log.i(TAG, "[Broadcast]PHONE_STATE");

doReceivePhone(context,intent);

}

}

/**

* 处理电话广播.

* @param context

* @param intent

*/

public void doReceivePhone(Context context, Intent intent) {

String phoneNumber = intent.getStringExtra(

TelephonyManager.EXTRA_INCOMING_NUMBER);

TelephonyManager telephony =

(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

int state = telephony.getCallState();

switch(state){

case TelephonyManager.CALL_STATE_RINGING:

Log.i(TAG, "[Broadcast]等待接电话="+phoneNumber);

break;

case TelephonyManager.CALL_STATE_IDLE:

Log.i(TAG, "[Broadcast]电话挂断="+phoneNumber);

break;

case TelephonyManager.CALL_STATE_OFFHOOK:

Log.i(TAG, "[Broadcast]通话中="+phoneNumber);

break;

}

}

}

定义Actitvity类

package com.zhouzijing.android.demo;

import android.app.Activity;

import android.content.Context;

import android.content.Intent;

import android.content.IntentFilter;

import android.os.Bundle;

import android.telephony.PhoneStateListener;

import android.telephony.TelephonyManager;

import android.util.Log;

import android.view.View;

public class MyBroadcastReceiver extends Activity {

public final static String TAG = "MyBroadcastReceiver";

public final static String B_PHONE_STATE =

TelephonyManager.ACTION_PHONE_STATE_CHANGED;

private BroadcastReceiverMgr mBroadcastReceiver;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.my_broadcast_receiver);

}

//按钮1-注册广播

public void registerIt(View v) {

Log.i(TAG, "registerIt");

mBroadcastReceiver = new BroadcastReceiverMgr();

IntentFilter intentFilter = new IntentFilter();

intentFilter.addAction(B_PHONE_STATE);

intentFilter.setPriority(Integer.MAX_VALUE);

registerReceiver(mBroadcastReceiver, intentFilter);

}

//按钮2-撤销广播

public void unregisterIt(View v) {

Log.i(TAG, "unregisterIt");

unregisterReceiver(mBroadcastReceiver);

}

}

方式二：通过监听器来实现


package com.zhouzijing.android.demo;

import android.app.Activity;

import android.content.Context;

import android.content.Intent;

import android.content.IntentFilter;

import android.os.Bundle;

import android.telephony.PhoneStateListener;

import android.telephony.TelephonyManager;

import android.util.Log;

import android.view.View;

public class MyBroadcastReceiver extends Activity {

public final static String TAG = "MyBroadcastReceiver";

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.my_broadcast_receiver);

}

/**

* 按钮-监听电话

* @param v

*/

public void createPhoneListener(View v) {

TelephonyManager telephony = (TelephonyManager)getSystemService(

Context.TELEPHONY_SERVICE);

telephony.listen(new OnePhoneStateListener(),

PhoneStateListener.LISTEN_CALL_STATE);

}

/**

* 电话状态监听.

* @author stephen

*/

class OnePhoneStateListener extends PhoneStateListener{

@Override

public void onCallStateChanged(int state, String incomingNumber) {

Log.i(TAG, "[Listener]电话号码:"+incomingNumber);

switch(state){

case TelephonyManager.CALL_STATE_RINGING:

Log.i(TAG, "[Listener]等待接电话:"+incomingNumber);

break;

case TelephonyManager.CALL_STATE_IDLE:

Log.i(TAG, "[Listener]电话挂断:"+incomingNumber);

break;

case TelephonyManager.CALL_STATE_OFFHOOK:

Log.i(TAG, "[Listener]通话中:"+incomingNumber);

break;

}

super.onCallStateChanged(state, incomingNumber);

}

}
