android-轻松监听来电和去电

　　要监听android打电话和接电话，只需下面2步骤
　　1.第一步，写一个Receiver继承自BroadcastReceiver

?

public class PhoneStatReceiver extends BroadcastReceiver{

private static final String TAG = "PhoneStatReceiver";

//        private static MyPhoneStateListener phoneListener = new MyPhoneStateListener();

private static boolean incomingFlag = false;

private static String incoming_number = null;

@Override

public void onReceive(Context context, Intent intent) {

//如果是拨打电话

if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){

incomingFlag = false;

String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);

Log.i(TAG, "call OUT:"+phoneNumber);

}else{

//如果是来电

TelephonyManager tm =

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

switch (tm.getCallState()) {

case TelephonyManager.CALL_STATE_RINGING:

incomingFlag = true;//标识当前是来电

incoming_number = intent.getStringExtra("incoming_number");

Log.i(TAG, "RINGING :"+ incoming_number);

break;

case TelephonyManager.CALL_STATE_OFFHOOK:

if(incomingFlag){

Log.i(TAG, "incoming ACCEPT :"+ incoming_number);

}

break;

case TelephonyManager.CALL_STATE_IDLE:

if(incomingFlag){

Log.i(TAG, "incoming IDLE");

}

break;

}

}

}

}　

 

　第二步：在AndroidManifest.xml，配置写好的Receiver，并拦截相应的BroadCastAction，
　　另外注意加上相应的权限。
　

?

<receiver android:name=".filter.PhoneStatReceiver">

　<intent-filter>

　<action android:name="android.intent.action.PHONE_STATE"/>

　<action android:name="android.intent.action.NEW_OUTGOING_CALL" />

　</intent-filter>

　</receiver>

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

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