Android監聽來電和去電

要監聽android打電話和接電話，只需下面2步驟第一步，寫一個Receiver繼承自BroadcastReceiverimport 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 PhoneStateBroadCastReceiver extends BroadcastReceiver{ private static final String TAG = "PhoneStateBroadCastReceiver";  private static boolean mIncomingFlag = false; private static String mIncomingNumber = null;  @Override public void onReceive(Context context, Intent intent) {  // 如果是撥打到電話  if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL))  {   mIncomingFlag = false;   String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);   Log.i(TAG, "call OUT:" + phoneNumber);  } else  {   // 如果是來電   TelephonyManager tManager =   (TelephonyManager) context.getSystemService(Service.TELEPHONY_SERVICE);   switch (tManager.getCallState())   {   case TelephonyManager.CALL_STATE_RINGING:    mIncomingNumber = intent.getStringExtra("incoming_number");    Log.i(TAG, "RINGING :" + mIncomingNumber);    break;   case TelephonyManager.CALL_STATE_OFFHOOK:    if (mIncomingFlag)    {     Log.i(TAG, "incoming ACCEPT :" + mIncomingNumber);    }    break;   case TelephonyManager.CALL_STATE_IDLE:    if (mIncomingFlag)    {     Log.i(TAG, "incoming IDLE");    }    break;   }  } } }第二步：在AndroidManifest.xml，配置寫好的Receiver，並攔截相應的BroadCastAction，另外注意加上相應的許可權<receiver android:name=".broadcase.PhoneStateBroadCastReceiver">             <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 android:name="android.permission.PROCESS_OUTGOING_CALLS" />
