這里主要是總結一下如何監聽有未接來電的問題
1.1 使用廣播接收器 BrocastReceiver
實現思路 :
靜態注冊監聽android.intent.action.PHONE_STATE 的廣播接收器 當手機的狀態改變后將會觸發 onReceive.
手機的狀態分為CALL_STATE_RINGING(響鈴中),CALL_STATE_IDLE(空閑),CALL_STATE_OFFHOOK(忙音).
也就是說當你沒有任何電話是，狀態是 IDLE ，當接到電話時是 OFFHOOK ，電話結束后返回 IDLE 狀態。
記錄上一次的手機狀態,如果的手機現在的空閑,上次的狀態響鈴中的話,就可以判斷是未接來電.
<uses-permission android:name="android.permission.READ_PHONE_STATE"/> <receiver android:name="com.example.phonestatedemo.receiver.PhoneStateReceiver"> <intent-filter > <action android:name="android.intent.action.PHONE_STATE"/> </intent-filter> </receiver>
import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.telephony.TelephonyManager; import android.util.Log; import android.widget.Toast; public class PhoneStateReceiver extends BroadcastReceiver { private static int lastCallState = TelephonyManager.CALL_STATE_IDLE; @Override public void onReceive(Context arg0, Intent arg1) { String action = arg1.getAction(); Log.d("PhoneStateReceiver", action ); TelephonyManager telephonyManager = (TelephonyManager) arg0 .getSystemService(Context.TELEPHONY_SERVICE); int currentCallState = telephonyManager.getCallState(); Log.d("PhoneStateReceiver", "currentCallState=" + currentCallState ); if (currentCallState == TelephonyManager.CALL_STATE_IDLE) {// 空閑 //TODO } else if (currentCallState == TelephonyManager.CALL_STATE_RINGING) {// 響鈴 //TODO } else if (currentCallState == TelephonyManager.CALL_STATE_OFFHOOK) {// 接聽 //TODO } if(lastCallState == TelephonyManager.CALL_STATE_RINGING && currentCallState == TelephonyManager.CALL_STATE_IDLE){ Toast.makeText(arg0, "有未接來電", 1).show(); } lastCallState = currentCallState; } } 1.2 使用 PhoneStateListener
實現思路 :
繼承PhoneStateListener后,當手機的狀態改變后將會觸發onCallStateChanged.手機的狀態分為CALL_STATE_RINGING(響鈴中),CALL_STATE_IDLE(空閑),CALL_STATE_OFFHOOK(忙音).
也就是說當你沒有任何電話是，狀態是 IDLE ，當接到電話時是 OFFHOOK ，電話結束后返回 IDLE 狀態。
記錄上一次的手機狀態,如果的手機現在的空閑,上次的狀態響鈴中的話,就可以判斷是未接來電.
不足:現在的處理不能判斷出是用戶是否主動不接電話.
TelephonyManager telephonyManager = (TelephonyManager) this .getSystemService(Context.TELEPHONY_SERVICE); telephonyManager.listen(new CallStateListener(this), PhoneStateListener.LISTEN_CALL_STATE); package com.example.phonestatedemo.listener; import android.content.Context; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.util.Log; import android.widget.Toast; public class CallStateListener extends PhoneStateListener { private static int lastetState = TelephonyManager.CALL_STATE_IDLE; // 最后的狀態 private Context context; public CallStateListener(Context context) { this.context = context; } @Override public void onCallStateChanged(int state, String incomingNumber) { // TODO Auto-generated method stub super.onCallStateChanged(state, incomingNumber); Log.d("CallStateListener", "onCallStateChanged state=" + state ); // 如果當前狀態為空閑,上次狀態為響鈴中的話,則破觚為認為是未接來電 if (lastetState == TelephonyManager.CALL_STATE_RINGING && state == TelephonyManager.CALL_STATE_IDLE) { //TODO Toast.makeText(this.context, "CallStateListener 有未接來電", 1).show(); } lastetState = state; } } 新聞熱點
