Android有未接来电后处理(判断未接来电)

在Android的手机状态中没有未接来电的监听器,所以如果想当手机有未接来电后进行处理,这时候就需要自己对手机的状态判断是未接来电后再进行处理.

实现思路 :
1,继承PhoneStateListener后,当手机的状态改变后将会触发onCallStateChanged.手机的状态分为CALL_STATE_RINGING(响铃中),CALL_STATE_IDLE(空闲),CALL_STATE_OFFHOOK(忙音).
2,记录上一次的手机状态,如果的手机现在的空闲,上次的状态响铃中的话,就可以判断是未接来电.

不足:
1,我现在的处理不能判断出是用户是否主动不接电话.

实现步骤:
1,编写CallListener,处理手机状态变更监听,当状态改变时进行处理。如果想知道如何在Android发送短信可以看我另一博文[ Android中发送短信(sms) ]

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; /** * @author www.r-base.net */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,则破觚为认为是未接来电if(lastetState ==  TelephonyManager.CALL_STATE_RINGING         && state == TelephonyManager.CALL_STATE_IDLE){sendSmgWhenMissedCall(incomingNumber);} // 最后的时候改变当前值lastetState = state;} private void sendSmgWhenMissedCall(String incomingNumber) {     // ... 进行未接来电处理(发短信,发email等等通知)}}

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; /** * @author www.r-base.net */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节点下添加如下代码.进行注册电话状态改变广播接收.

123456789

 ...>   ...>     android:name=".call.service.CallReceiver">     android:priority="100">     android:name="android.intent.action.PHONE_STATE" />    >    >  >>

4,在AndroidManifest.xml中添加读取手机状态的权限.

1	android:name="android.permission.READ_PHONE_STATE" />
