通常來說Android手機(jī)沒有未接來電的監(jiān)聽器，如果要實(shí)現(xiàn)對未接來電的處理，則需要自己編寫程序來實(shí)現(xiàn)。本文所述程序?qū)嵗礊锳ndroid實(shí)現(xiàn)判斷手機(jī)未接來電及處理方法。主要分為四個(gè)步驟來進(jìn)行：
1、編寫CallListener,處理手機(jī)狀態(tài)變更監(jiān)聽,當(dāng)狀態(tài)改變時(shí)進(jìn)行處理：
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; //最后的狀態(tài)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;// 如果當(dāng)前狀態(tài)為空閑,上次狀態(tài)為響鈴中的話,則認(rèn)為是未接來電if(lastetState == TelephonyManager.CALL_STATE_RINGING&& state == TelephonyManager.CALL_STATE_IDLE){sendSmgWhenMissedCall(incomingNumber);}//最后改變當(dāng)前值lastetState = state;}private void sendSmgWhenMissedCall(String incomingNumber) {//未接來電處理(發(fā)短信,發(fā)email等)}}2、編寫CallReceiver，注冊來電廣播接收器：
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節(jié)點(diǎn)下注冊電話狀態(tài)改變的廣播接收：
<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中添加讀取手機(jī)狀態(tài)的權(quán)限：
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
通過以上的步驟,當(dāng)手機(jī)有未接來電時(shí) sendSmgWhenMissedCall 該方法就會觸發(fā),就可以進(jìn)行相應(yīng)的處理。
