我無法點擊我的導航器菜單？

Question

我的導航菜單中有一個非常有趣的問題。我不知道爲什麼...但我不能點擊我的菜單中的任何項目，我真的想說我不能點擊任何項目。我試圖做一個新的項目女巫已經有導航抽屜活動，當然它的作品..但是當我已經嘗試複製該代碼，並把我的..我有同樣的問題，反之亦然，我已經嘗試將我的代碼放入帶有「導航抽屜活動」的新項目中，但又是如此。

這是我的主要活動

嗯，我看到上面的代碼看起來離我有兩件事情。您正在使Fragment Transaction成爲一個類級別的變量，但這些變量通常是每個事務的新變量，但這不太可能與您的問題相關，只需提一提。

然後，當您選擇的導航項目被觸發時，您將啓動一項新活動，但您並未共享該代碼。當您使用導航抽屜時，通常只需從主活動導航抽屜碎片區域中的佔位符標識中替換碎片。

以下是帶抽屜佈局的活動示例。

     </RelativeLayout> 

    </android.support.design.widget.NavigationView> 

</android.support.v4.widget.DrawerLayout> 

我經常做我的主，別人BaseActivity，將包括一個swapFragment例行所以它就像共享：

protected void swapFragment(BaseFragment fragment, @Nullable Bundle bundle) { 
    if (fragment.isVisible()) { 
     return; 

    } 

    A35Log.v(TAG, "swapFragment(" + fragment.getClass().getSimpleName() + ")"); 
    Bundle currentFragBundle = fragment.getArguments(); 
    if (currentFragBundle == null && bundle != null) { 
     fragment.setArguments(bundle); 

    } else if (bundle != null) { 
     fragment.getArguments().putAll(bundle); 

    } 


    FragmentManager fragmentManager = getSupportFragmentManager(); 
    fragmentManager.executePendingTransactions(); 

    //Make sure the requested fragment isn't already on the screen before adding it 
    if (fragment.isAdded()) { 
     if (fragment.isHidden()) { 
      fragmentManager.beginTransaction().show(fragment).commit(); 

     } 

     A35Log.v(TAG, "Fragment was hidden, so removeFullScreen instead of replace"); 
     return; 

    } 

    mSelectedFragment = fragment; 
    A35Log.v(TAG, "Replacing Active Fragment with " + fragment.getClass().getSimpleName()); 

    FragmentManager manager = getSupportFragmentManager(); 
    FragmentTransaction fragmentTransaction = manager.beginTransaction(); 
    fragmentTransaction.replace(R.id.fragPlaceholder, fragment); 
    fragmentTransaction.commit(); 

} 

當然，我使用數據綁定這樣的方式它是有線的有點不同，但希望這會指出你的問題。我猜這是一個Z索引問題，所以檢查你的佈局文件可能會揭示答案。

如果沒有，請提供您的示例項目或至少您的XML佈局文件，如果可能的話，看看。由於這通常是覆蓋物阻塞觸摸的問題，並且可能由任何事物引起。您可以將佈局按順序排列，以便Z索引將抽屜放在內容之下而不是放在其前面。如果發生這種情況，您的佈局會將觸摸傳遞給內容而不是抽屜。所以檢查一下。
