android-轻松监听来电和去电

2021-01-24

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

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
StringphoneNumber=intent.getStringExtra(
TelephonyManager.EXTRA_INCOMING_NUMBER);

TelephonyManagertelephony=

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

intstate=telephony.getCallState();

switch(state){

caseTelephonyManager.CALL_STATE_RINGING:

Log.i(TAG,"[Broadcast]等待接电话="+phoneNumber);

break;

caseTelephonyManager.CALL_STATE_IDLE:

Log.i(TAG,"[Broadcast]电话挂断="+phoneNumber);

break;

caseTelephonyManager.CALL_STATE_OFFHOOK:

Log.i(TAG,"[Broadcast]通话中="+phoneNumber);

break;
}
}
}
}

复制代码 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>
