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：

package rbase.app.smshelpmate.call.listener;
import java.text.messageformat;
import rbase.app.smshelpmate.config;
import rbase.app.smshelpmate.r;
import rbase.app.smshelpmate.call.enums.callstateenum;
import rbase.app.smshelpmate.forward.forwardmanager;
import rbase.app.smshelpmate.forward.enums.forwardtype;
import rbase.app.smshelpmate.forward.vo.forwardparam;
import android.content.context;
import android.telephony.phonestatelistener;
import android.telephony.telephonymanager;
import android.util.log;

public class calllistener extends phonestatelistener {
private static final string tag = "sms";
private static int lastetstate = telephonymanager.call_state_idle; //最后的状态
private context context;
public calllistener(context context) {
super();
this.context = context;
}
public void oncallstatechanged(int state, string incomingnumber) {
log.v(tag, "calllistener call state changed : " + incomingnumber);
string m = 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;
}
private void sendsmgwhenmissedcall(string incomingnumber) {
//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：

package rbase.app.smshelpmate.call.service;
import rbase.app.smshelpmate.const;
import rbase.app.smshelpmate.call.listener.calllistener;
import android.content.broadcastreceiver;
import android.content.context;
import android.content.intent;
import android.os.bundle;
import android.telephony.phonestatelistener;
import android.telephony.telephonymanager;
import android.util.log;
public class callreceiver extends broadcastreceiver{
public void onreceive(context context, intent intent) {
log.i("sms", "callreceiver start...");
telephonymanager telephony = (telephonymanager) context
.getsystemservice(context.telephony_service);
calllistener customphonelistener = new calllistener(context);
telephony.listen(customphonelistener,
phonestatelistener.listen_call_state);
bundle bundle = intent.getextras();
string phonenr = bundle.getstring("incoming_number");
log.i("sms", "callreceiver phone number : " + 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 ...>
<receiver android:name=".call.service.callreceiver">
<intent-filter android:priority="100">
<action android: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-permission android: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。
