android-獲取手機電話的狀態

無論是打電話還是來電，系統廣播是會發送相應的消息的，我們可以監聽廣播獲取手機電話狀態。

首先在manifest文件中配置自己的BroadcastReceiver，和聲明權限。

<receiver android:name=".filter.PhoneStatReceiver"> <intent-filter> <action android:name="android.intent.action.PHONE_STATE"/> <action android:name="android.intent.action.NEW_OUTGOING_CALL" /> </intent-filter> </receiver> <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission> <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission>
在自己的BroadcastReceiver中做相應的處理

import android.app.Service; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.telephony.TelephonyManager; import android.util.Log; public class PhoneStatReceiver extends BroadcastReceiver{ private static final String TAG = "PhoneStatReceiver"; private static boolean incomingFlag = false; private static String incoming_number = null; @Override public void onReceive(Context context, Intent intent) { //如果是撥打電話 if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){ incomingFlag = false; String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); Log.i(TAG, "call OUT:"+phoneNumber); }else{ //如果是來電 TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE); switch (tm.getCallState()) { case TelephonyManager.CALL_STATE_RINGING: incomingFlag = true;//標識當前是來電 incoming_number = intent.getStringExtra("incoming_number"); Log.i(TAG, "RINGING :"+ incoming_number); break; case TelephonyManager.CALL_STATE_OFFHOOK: //存在至少有一個呼叫撥號，活躍，或 //保留，並沒有來電振鈴或等待 if(incomingFlag){ Log.i(TAG, "incoming ACCEPT :"+ incoming_number); } break; case TelephonyManager.CALL_STATE_IDLE: //閑置狀態 if(incomingFlag){ Log.i(TAG, "incoming IDLE"); } break; } } } }
