想了解Android监听来电和去电的实现方法的相关内容吗,与时俱进在本文为您仔细讲解Android监听来电和去电的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Android,监听,来电,去电,下面大家一起来学习吧。

本文实例讲述了Android监听来电和去电的实现方法。分享给大家供大家参考,具体如下:

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" />

PS:这里再为大家提供一个关于AndroidManifest.xml权限控制的在线查询工具:
