如何在Android應用程序中獲取通話結束事件

Question

我爲Android手機制作了一個小應用程序。

在一種情況下，我沒有得到任何解決方案。 其實我的應用程序有很小的功能來打電話給客戶。

所以通話結束後，我需要最後一個號碼將被撥打或運行哪個應用程序的事件。

AndroidManifest：

<receiver android:name=".PhoneStateBroadcastReceiver"> 
     <intent-filter> 
       <action android:name="android.intent.action.PHONE_STATE">  
     </action></intent-filter> 
</receiver> 

添加以下權限：

<uses-permission android:name="android.permission.READ_PHONE_STATE"> 
</uses-permission> 

PhoneStateBroadcastReceiver.java（重構的碼位）

package com.mobisys.android.salesbooster;

import android.content.BroadcastReceiver;

import android.preference.PreferenceManager; 
import android.provider.ContactsContract.PhoneLookup; 
import android.telephony.PhoneStateListener; 
import android.telephony.TelephonyManager; 
import android.util.Log; 

public class PhoneStateBroadcastReceiver extends BroadcastReceiver { 

    private static final String TAG = "PhoneStateBroadcastReceiver"; 
    Context mContext; 
    String incoming_number; 
    private int prev_state; 

    @Override 
    public void onReceive(Context context, Intent intent) { 
     TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); //TelephonyManager object 
     CustomPhoneStateListener customPhoneListener = new CustomPhoneStateListener(); 
     telephony.listen(customPhoneListener, PhoneStateListener.LISTEN_CALL_STATE); //Register our listener with TelephonyManager 

     Bundle bundle = intent.getExtras(); 
     String phoneNr = bundle.getString("incoming_number"); 
     Log.v(TAG, "phoneNr: "+phoneNr); 
     mContext = context; 
    } 

    /* Custom PhoneStateListener */ 
    public class CustomPhoneStateListener extends PhoneStateListener { 

     private static final String TAG = "CustomPhoneStateListener"; 

     @Override 
     public void onCallStateChanged(int state, String incomingNumber){ 

      if(incomingNumber != null && incomingNumber.length() > 0) 
      incoming_number = incomingNumber; 

      switch(state){ 
       case TelephonyManager.CALL_STATE_RINGING: 
         Log.d(TAG, "CALL_STATE_RINGING"); 
         prev_state=state; 
         break; 

       case TelephonyManager.CALL_STATE_OFFHOOK: 
           Log.d(TAG, "CALL_STATE_OFFHOOK"); 
           prev_state=state; 
           break; 

       case TelephonyManager.CALL_STATE_IDLE: 

        Log.d(TAG, "CALL_STATE_IDLE==>"+incoming_number); 

        if((prev_state == TelephonyManager.CALL_STATE_OFFHOOK)){ 
         prev_state=state; 
         //Answered Call which is ended 
        } 
        if((prev_state == TelephonyManager.CALL_STATE_RINGING)){ 
         prev_state=state; 
         //Rejected or Missed call 
        } 
        break; 
      }

    }
