原生界面（android）問題的權限

我需要在cn1中寫入原生android代碼的權限。但是下面的代碼並不要求權限，但給出了空白屏幕。在調試時，下面提到的調試的第二部分會無限重複。原生界面（android）問題的權限

import android.Manifest; 
import android.support.v4.app.ActivityCompat; 
import android.util.Log; 
import com.codename1.impl.android.AndroidNativeUtil; 

public class FusedLocationImpl implements ConnectionCallbacks, 
     OnConnectionFailedListener{ 

    public boolean isSupported() { 
     return true; 
    } 

    public void getFusedLocationPermission() { 
     if (!com.codename1.impl.android.AndroidNativeUtil.checkForPermission(Manifest.permission.CAMERA, "Please allow camera permission")) { 
      ActivityCompat.requestPermissions((android.app.Activity) MyApplication.getContext(), new String[]{Manifest.permission.CAMERA}, 0); 
      //commenting this line does nothing 
     } 
    } 
}

FusedLocation.java

public interface FusedLocation extends NativeInterface{ 
    public void getFusedLocationPermission(); 
}

MyApplication.java

public void start() { 
    if (current != null) { 
     current.show(); 
     return; 
    } 
    FusedLocation my = (FusedLocation) NativeLookup.create(FusedLocation.class); 
    if(my != null && my.isSupported()){ 
     my.getFusedLocationPermission(); 
     System.out.println("bbeck"); 
    } 
    Form hi = new Form("Hi World", BoxLayout.y()); 
    hi.add(new Label("Hi World")); 
    hi.show(); 
} 

public static Object getContext() { 
    return context; 
}

開始都會發生應用程序啓動時。您正在請求獲得允許打開本機對話框的權限。應用程序被暫停。應用程序得到恢復，你再次要求許可...

通常這個代碼不會被達成，因爲你會暫停當前形式，但你甚至沒有足夠的時間發生。

在這個階段詢問權限是不好的，在本機和Codename One應用程序中。

沒有UI顯示，如果用戶說不，你卡住了。你需要一個上下文來顯示，然後詢問用戶的許可。

其實權限是在一個btn動作偵聽器中。我要求ACCESS_FINE_LOCATION使用融合地點。以上只是一個例子。請看看上面的update1。 Thankyou – beck

您是否也向android.xpermissions構建提示添加了權限？如果被用戶拒絕，你爲什麼又要提示許可？我們已經這麼做了，如果你也這樣做了，它也不會很好看。 –

ohhh thankyou ...我忘了添加android.xpermissions提示。如果權限被用戶拒絕，我不知道該返回什麼，所以再次詢問。 – beck
