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>
