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;@Overridepublic 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>
