Android实现判断手机未接来电及处理方法
通常来说Android手机没有未接来电的监听器，如果要实现对未接来电的处理，则需要自己编写程序来实现。本文所述程序实例即为Android实现判断手机未接来电及处理方法。主要分为四个步骤来进行：
1、编写CallListener,处理手机状态变更监听,当状态改变时进行处理：
packagerbase.app.smshelpmate.call.listener;
importjava.text.MessageFormat;
importrbase.app.smshelpmate.Config;
importrbase.app.smshelpmate.R;
importrbase.app.smshelpmate.call.enums.CallStateEnum;
importrbase.app.smshelpmate.forward.ForwardManager;
importrbase.app.smshelpmate.forward.enums.ForwardType;
importrbase.app.smshelpmate.forward.vo.ForwardParam;
importandroid.content.Context;
importandroid.telephony.PhoneStateListener;
importandroid.telephony.TelephonyManager;
importandroid.util.Log;
publicclassCallListenerextendsPhoneStateListener{
privatestaticfinalStringTAG="sms";
privatestaticintlastetState=TelephonyManager.CALL_STATE_IDLE;//最后的状态
privateContextcontext;
publicCallListener(Contextcontext){
super();
this.context=context;
}
publicvoidonCallStateChanged(intstate,StringincomingNumber){
Log.v(TAG,"CallListenercallstatechanged:"+incomingNumber);
Stringm=null;
//如果当前状态为空闲,上次状态为响铃中的话,则认为是未接来电
if(lastetState==TelephonyManager.CALL_STATE_RINGING
&&state==TelephonyManager.CALL_STATE_IDLE){
sendSmgWhenMissedCall(incomingNumber);
}
//最后改变当前值
lastetState=state;
}
privatevoidsendSmgWhenMissedCall(StringincomingNumber){
//未接来电处理(发短信,发email等)
}
}
2、编写CallReceiver，注册来电广播接收器：
packagerbase.app.smshelpmate.call.service;
importrbase.app.smshelpmate.Const;
importrbase.app.smshelpmate.call.listener.CallListener;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.os.Bundle;
importandroid.telephony.PhoneStateListener;
importandroid.telephony.TelephonyManager;
importandroid.util.Log;
publicclassCallReceiverextendsBroadcastReceiver{
publicvoidonReceive(Contextcontext,Intentintent){
Log.i("sms","CallReceiverStart...");
TelephonyManagertelephony=(TelephonyManager)context
.getSystemService(Context.TELEPHONY_SERVICE);
CallListenercustomPhoneListener=newCallListener(context);
telephony.listen(customPhoneListener,
PhoneStateListener.LISTEN_CALL_STATE);
Bundlebundle=intent.getExtras();
StringphoneNr=bundle.getString("incoming_number");
Log.i("sms","CallReceiverPhoneNumber:"+phoneNr);
}
}
3、在AndroidManifest.xml中的application节点下注册电话状态改变的广播接收：
<manifest...> <application...> <receiverandroid:name=".call.service.CallReceiver"> <intent-filterandroid:priority="100"> <actionandroid:name="android.intent.action.PHONE_STATE"/> </intent-filter> </receiver> </application> </manifest>
4、在AndroidManifest.xml中添加读取手机状态的权限：
<uses-permissionandroid:name="android.permission.READ_PHONE_STATE"/>
通过以上的步骤,当手机有未接来电时sendSmgWhenMissedCall该方法就会触发,就可以进行相应的处理。
