我的Navigator菜单有一个非常有趣的问题。我不知道为什么......但我无法点击菜单中的任何项目，我真的想说我无法点击任何项目。我尝试制作一个已经有导航抽屉活动的新项目，当然它可以工作..但是当我尝试复制那些代码然后放上我的...我有同样的问题，反之亦然，我尝试将我的代码放入一个带有导航抽屉活动的新项目中，但是又一次。
这是我的主要活动

我从上面的代码中看到了一些与我相关的东西。您正在将Fragment Transaction变为类级别变量，但这些变量通常是每个事务的新变量，但这可能与您的问题无关，只需提及。
然后，当您选择的导航项被触发时，您正在启动一项新活动，但您没有共享该代码。当您使用导航抽屉时，通常只需从主活动导航抽屉片段区域中的占位符ID换出片段。
以下是带抽屉布局的示例活动。

我经常为我的Main和其他人制作一个BaseActivity，并且会包含一个swapFragment例程，所以它共享如下：
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();
}
当然我使用DataBinding所以它的连接方式有点不同，但希望这可以指出你的问题。我猜这是一个Z索引问题，所以检查你的布局文件可能会揭示答案。
如果没有，请提供您的示例项目或至少您的xml布局文件（如果可能）。因为这通常是覆盖触摸的叠加问题，并且可能由任何数量的事物引起。您可能已将布局排除在外，因此Z索引将抽屉放在内容下而不是前面。如果发生这种情况，您的布局会将触摸传递给内容而不是抽屉。所以也要检查一下。
