切换状态recive的Android

Question

我有一个切换，当BATTERY_LOW是真的关闭无线网络：

public void getToggle(View view) { 
    // Is the toggle on? 
    boolean on = ((ToggleButton) view).isChecked(); 
    if (on) { 
      PackageManager pm = getPackageManager(); 
    ComponentName compName = 
    new ComponentName(getApplicationContext(), 
     LowBatteryReceiver.class); 
     pm.setComponentEnabledSetting(
     compName, 
     PackageManager.COMPONENT_ENABLED_STATE_ENABLED, 
     PackageManager.DONT_KILL_APP); 
    } else {     
      PackageManager pm = getPackageManager(); 
      ComponentName compName = 
      new ComponentName(getApplicationContext(), 
      LowBatteryReceiver.class); 
      pm.setComponentEnabledSetting(
      compName, 
      PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 
      PackageManager.DONT_KILL_APP);   
     } 
    } 

这里的WiFi代码：

public class LowBatteryReceiver extends BroadcastReceiver { 

    public void onReceive(Context context, Intent intent) { 
     wifiManager = (WifiManager) MainActivity.this.getSystemService(Context.WIFI_SERVICE); 
         wifiManager.setWifiEnabled(false); 
    } 
} 


public class OkBatteryReceiver extends BroadcastReceiver { 

    public void onReceive(Context context, Intent intent) { 
     wifiManager = (WifiManager) MainActivity.this.getSystemService(Context.WIFI_SERVICE); 
         wifiManager.setWifiEnabled(true); 
    } 
} 

我怎么能“记住”的选择当我离开我的应用程序并再次打开它时切换？我知道我必须在onResume和onCreate中写下一些东西，但我不知道当我使用BroadcastReceiver时是什么。我想我必须检查COMPONENT_ENABLED_STATE_DISABLED或COMPONENT_ENABLED_STATE_ENABLED是不是对的？有人可以帮助我吗？由于

我建议你阅读有关Android中保存数据： http://developer.android.com/training/basics/data-storage/index.html

//set Preference 
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE); 
SharedPreferences.Editor editor = sharedPref.edit(); 
editor.putInt(getString(R.string.saved_high_score), newHighScore); 
editor.commit(); 

//get Preference 
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE); 
int defaultValue = getResources().getInteger(R.string.saved_high_score_default); 
long highScore = sharedPref.getInt(getString(R.string.saved_high_score), defaultValue);
