Android - 从类中取消注册BroadcastReceiver？

如何从类中注销接收者？到目前为止，我得到了这个代码..当我第一次按下按钮，一切正常，但是当我再次按它时，应用程序崩溃，错误：..错误接收广播意图...和错误不处理。据我的理解，我不能注册接收器两次，但如何克服这一点？Android - 从类中取消注册BroadcastReceiver？

public class ApplianceButtonToggleOnClickListener implements OnCheckedChangeListener { 
LinearLayoutWithImage mHardwareCell; 
Activity mActivity; 
    public ApplianceButtonToggleOnClickListener(
      LinearLayoutWithImage mHardwareCell, Activity mActivity) { 
     this.mHardwareCell = mHardwareCell; 
     this.mActivity = mActivity; 
    } 

    @Override 
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
    ... 

      mActivity.startService(intentMyIntentService); 
      ApplianceStateChangeSuccessReceiver successReceiver = new ApplianceStateChangeSuccessReceiver(mActivity,mHardwareCell); 
      IntentFilter intentHardwareSyncFilter = new IntentFilter(UpdateHardwareStateService.ACTION_UpdateHardwareStateService); 
     intentHardwareSyncFilter.addCategory(Intent.CATEGORY_DEFAULT);  


     try { 
      mActivity.registerReceiver(successReceiver, intentHardwareSyncFilter);} catch (IllegalArgumentException e) { 
       Log.d ("APPLIANCE_BUTTON_TOGGLE_ON_CLICK", "ApplianceButtonToggleOnClick: error " +e); 
      } 



    } 

}

保持的全局引用您的接收器，并注册/，分别注销它在你的onStart()和onStop()方法。此外，如果您收到“接收广播意图的错误”，则说明您的接收器可能正在接收广播，而您正在处理错误 - 但是，没有看到堆栈跟踪/您的接收器代码主要只是猜测。这里有一个简单的例子：

public class MainActivity extends Activity { 

BroadcastReceiver yourReceiver; 

    @Override 
    protected void onCreate(Bundle bundle){ 
     super.onCreate(bundle); 
     yourReceiver = new YourImplementation(); 
    } 

    @Override 
    protected void onStart(){ 
     super.onStart(); 
     registerReceiver(yourReceiver, new IntentFilter(YOURACTION)); 
    } 

    @Override 
    protected void onStop(){ 
     super.onStop(); 
     unregisterReceiver(yourReceiver); 
    } 

}

要注册和的onResume（）和注销的onPause接收器（）。

@Override 
    protected void onResume(){ 
     super.onStart(); 
     registerReceiver(yourReceiver, new IntentFilter(YOURACTION)); 
    } 

    @Override 
    protected void onPause(){ 
     super.onStop(); 
     unregisterReceiver(yourReceiver); 
    }
