Android中監(jiān)聽未接來電的2種方法

這篇文章主要介紹了Android中監(jiān)聽未接來電的2種方法,本文講解了使用廣播接收器 BrocastReceiver和使用 PhoneStateListener二種方法,需要的朋友可以參考下

這里主要是總結(jié)一下如何監(jiān)聽有未接來電的問題

1.1 使用廣播接收器 BrocastReceiver
實(shí)現(xiàn)思路 :
靜態(tài)注冊監(jiān)聽android.intent.action.PHONE_STATE 的廣播接收器當(dāng)手機(jī)的狀態(tài)改變后將會(huì)觸發(fā) onReceive.
手機(jī)的狀態(tài)分為CALL_STATE_RINGING(響鈴中),CALL_STATE_IDLE(空閑),CALL_STATE_OFFHOOK(忙音).
也就是說當(dāng)你沒有任何電話是，狀態(tài)是 IDLE ，當(dāng)接到電話時(shí)是 OFFHOOK ，電話結(jié)束后返回 IDLE 狀態(tài)。
記錄上一次的手機(jī)狀態(tài),如果的手機(jī)現(xiàn)在的空閑,上次的狀態(tài)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(shí)現(xiàn)思路 :
繼承PhoneStateListener后,當(dāng)手機(jī)的狀態(tài)改變后將會(huì)觸發(fā)onCallStateChanged.手機(jī)的狀態(tài)分為CALL_STATE_RINGING(響鈴中),CALL_STATE_IDLE(空閑),CALL_STATE_OFFHOOK(忙音).
也就是說當(dāng)你沒有任何電話是，狀態(tài)是 IDLE ，當(dāng)接到電話時(shí)是 OFFHOOK ，電話結(jié)束后返回 IDLE 狀態(tài)。
記錄上一次的手機(jī)狀態(tài),如果的手機(jī)現(xiàn)在的空閑,上次的狀態(tài)響鈴中的話,就可以判斷是未接來電.

不足:現(xiàn)在的處理不能判斷出是用戶是否主動(dòng)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(tài) 
  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(dāng)前狀態(tài)為空閑,上次狀態(tài)為響鈴中的話,則破觚為認(rèn)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; 
 
  } 
 
}
