Android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

 1 import android.app.Service; 2 import android.content.BroadcastReceiver; 3 import android.content.Context; 4 import android.content.Intent; 5 import android.telephony.TelephonyManager; 6 import android.util.Log; 7  8 public class PhoneStateBroadCastReceiver extends BroadcastReceiver 9 {10  private static final String TAG = "PhoneStateBroadCastReceiver";11 12  private static boolean mIncomingFlag = false;13  private static String mIncomingNumber = null;14 15  @Override16  public void onReceive(Context context, Intent intent)17  {18   // 如果是拨打电话19   if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL))20   {21    mIncomingFlag = false;22    String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);23    Log.i(TAG, "call OUT:" + phoneNumber);24   } else25   {26    // 如果是来电27    TelephonyManager tManager =28    (TelephonyManager) context.getSystemService(Service.TELEPHONY_SERVICE);29    switch (tManager.getCallState())30    {31    case TelephonyManager.CALL_STATE_RINGING:32     mIncomingNumber = intent.getStringExtra("incoming_number");33     Log.i(TAG, "RINGING :" + mIncomingNumber);34     break;35    case TelephonyManager.CALL_STATE_OFFHOOK:36     if (mIncomingFlag)37     {38      Log.i(TAG, "incoming ACCEPT :" + mIncomingNumber);39     }40     break;41    case TelephonyManager.CALL_STATE_IDLE:42     if (mIncomingFlag)43     {44      Log.i(TAG, "incoming IDLE");45     }46     break;47    }48   }49  }50 51 }

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

1 <receiver android:name=".broadcase.PhoneStateBroadCastReceiver"> 2             <intent-filter>3                <action android:name="android.intent.action.PHONE_STATE"/>          4                <action android:name="android.intent.action.NEW_OUTGOING_CALL" />5            </intent-filter>6   </receiver>7 <uses-permission android:name="android.permission.READ_PHONE_STATE" />8 <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
