android sim卡听众

Question

HI全部

我想在我的服务类中实现getSimstate（）侦听器。我无法做到这一点。

我知道它可以在Telephony类中的sim侦听器的帮助下完成。但我没有得到任何代码来实现它。

如果有人是有码听SIM枯萎准备好或不...请给我...

Answer 1

final TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE); 

     tm.listen(new PhoneStateListener() { 
      @Override 
      public void onServiceStateChanged(ServiceState serviceState) { 
       //Code in here executed when the sim state has changed 
      } 

      @Override 
      public void onDataConnectionStateChanged(int state) { 

      } 
});

清单文件

<receiver 
     android:name=".SimChangedReceiver" 
     android:enabled="true" 
     android:process=":remote" > 
     <intent-filter> 
      <action android:name="android.intent.action.SIM_STATE_CHANGED" /> 
     </intent-filter> 
     <intent-filter> 
      <action android:name="android.intent.action.BOOT_COMPLETED" /> 
     </intent-filter> 
    </receiver> 

SimChangedReceiver类

public class SimChangedReceiver extends BroadcastReceiver { 

    public void onReceive(Context context, Intent intent) { 
     String action = intent.getAction(); 
     if (action.equalsIgnoreCase("android.intent.action.SIM_STATE_CHANGED")) { 
      Log.d("SimChangedReceiver", "--> SIM state changed <--"); 
     } 
    } 
}
