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

第一步，写一个Receiver继承自BroadcastReceiver

import android.app.Service;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.telephony.TelephonyManager;

import android.util.Log;

 

public class PhoneStateBroadCastReceiver extends BroadcastReceiver

{

 private static final String TAG = "PhoneStateBroadCastReceiver";

 

 private static boolean mIncomingFlag = false;

 private static String mIncomingNumber = 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))

  {

   mIncomingFlag = false;

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

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

  } else

  {

   // 如果是来电

   TelephonyManager tManager =

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

   switch (tManager.getCallState())

   {

   case TelephonyManager.CALL_STATE_RINGING:

    mIncomingNumber = intent.getStringExtra("incoming_number");

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

    break;

   case TelephonyManager.CALL_STATE_OFFHOOK:

    if (mIncomingFlag)

    {

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

    }

    break;

   case TelephonyManager.CALL_STATE_IDLE:

    if (mIncomingFlag)

    {

     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=".broadcase.PhoneStateBroadCastReceiver"> 

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