Android监听来电和去电

android中监听来电和去电，这种功能的实现也许会在一些项目中经常实现，尤其一些防盗软件，这里为大家分享一下很不错的Android监听来电和去电的源码：

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

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" />
