监听电话状态

class MyPhoneStateListener extends PhoneStateListener { @Override public void onCallStateChanged( int state, String incomingNumber) { switch (state) { case TelephonyManager.CALL_STATE_IDLE: // 空闲 break ; case TelephonyManager.CALL_STATE_RINGING: // 来电 break ; case TelephonyManager.CALL_STATE_OFFHOOK: // 摘机（正在通话中） break ; } } } // 获取电话通讯服务 TelephonyManager tpm = (TelephonyManager) this .getSystemService(Context.TELEPHONY_SERVICE); // 创建一个监听对象，监听电话状态改变事件 tpm.listen( new MyPhoneStateListener(), PhoneStateListener.LISTEN_CALL_STATE);

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

来电action为TelephonyManager.ACTION_PHONE_STATE_CHANGED

去电action为Intent.ACTION_NEW_OUTGOING_CALL

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 >
