Question

我的操作栏出了问题，所以我在那里有自定义列表视图的活动，当我打开thoose活动屏幕加载出现，我可以看到我的操作栏，但当数据加载（从json）动作栏消失，只有我看到的常见列表视图，请有人帮我解决这个问题< / p>

这里是我的代码：

$sourceArray = .... your source array here :)
$attractieIDs = array(41, 52);

foreach($attractieIDs as $id) {
   foreach($sourceArray[$id] as $attr) {
     $myOrders[] = $attr;
   }
}

首先，您应该将app_bar_main.xml放入content_main.xml 然后在LinearLayout中，您应该在CoordinatorLayout下面添加content_main layout (that will contains ListView)，以使ActionBar始终低于<?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" tools:context=".MainActivity"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <android.support.design.widget.AppBarLayout android:layout_height="wrap_content" android:layout_width="match_parent" android:theme="@style/AppTheme.AppBarOverlay"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" app:popupTheme="@style/AppTheme.PopupOverlay" /> </android.support.design.widget.AppBarLayout> <include layout="@layout/content_main" /> <android.support.design.widget.FloatingActionButton android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom|end" android:layout_margin="@dimen/fab_margin" android:src="@android:drawable/ic_media_next" /> </LinearLayout> </android.support.design.widget.CoordinatorLayout>（工具栏）
