android 电话状态的监听(来电和去电) PhoneStateListener和TelephonyManager
今天的程序可以实现电话状态改变时启动(来电、接听、挂断、拨打电话),但是暂时没法实现拨打电话时判断对方是否接听、转语音信箱等。Android在电话状态改变是会发送action为android.intent.action.PHONE_STATE的广播,而拨打电话时会发送action为android.intent.action.NEW_OUTGOING_CALL的广播,但是我看了下开发文档,暂时没发现有来电时的广播。知道这个就好办了,我们写个BroadcastReceiver用于接收这两个广播就可以了。
package com.pocketdigi.phonelistener;
import android.app.Service;
import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent;
import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager;
public class PhoneReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub
System.out.println(\"action\"+intent.getAction());
if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){ //如果是去电(拨出) System.out.println(\"拨出\");
}else{
//查了下android文档,貌似没有专门用于接收来电的action,所以,非去电即来电 System.out.println(\"来电\"); TelephonyManager tm =
(TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE); tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE); //设置一个监听器 } }
PhoneStateListener listener=new PhoneStateListener(){
@Override
public void onCallStateChanged(int state, String incomingNumber) { // TODO Auto-generated method stub
//state 当前状态 incomingNumber,貌似没有去电的API super.onCallStateChanged(state, incomingNumber); switch(state){
case TelephonyManager.CALL_STATE_IDLE: System.out.println(\"挂断\"); break;
case TelephonyManager.CALL_STATE_OFFHOOK: System.out.println(\"接听\"); break;
case TelephonyManager.CALL_STATE_RINGING:
System.out.println(\"响铃:来电号码\"+incomingNumber); //输出来电号码 break; } }
}; }
要在AndroidManifest.xml注册广播接收器:
