Android 协调布局中未显示的内容？

我正在尝试在“活动”中实现工具栏，但在使用实现工具栏后尝试运行应用程序时

DrawerLayout >> CoordinatorLayout >> AppBarLayout

内容不显示。这是布局文件

但当我将内容移动到AppBarLayout中时，除了appbar内，所有内容都是可见的。如何解决这个问题？任何想法。

改变

<LinearLayout
    android:id="@+id/RelativeLayout1"
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="0.05"
    android:background="@drawable/header"
    android:baselineAligned="false"
    android:gravity="center" >

---

使用Cordinator布局时，布局应如下所示

<CoordinatorLayout>
<AppBarLayout>
   //Toolbar and other contents should come here
</AppBarLayout>

<Recycler Or Nested Scroll View>

<LinearLayout
app:layout_behavior="@string/appbar_scrolling_view_behavior">

 //This is used when you have a collapsing toolbar and you need to add a scrolling behaviour for your views.

<LinearLayout/>

<Recycler Or Nested Scroll View/>

//工具栏和其他内容应该在这里
//当您有一个折叠工具栏，并且需要为视图添加滚动行为时，可以使用此选项。

相反，尝试这种布局

您的线性布局高度固定为0，因此不可扩展。使用

包装内容或匹配父项。

有时坐标布局不适用于API版本25或更低版本，如果您将其用于应用程序，请更改其他内容，如框架、线性或相对。。。。

---

布局也具有时间复杂性，即帧O（1）、线性（n）、相对O（n2）

我尝试使用match\u parent更改布局高度，但hotchpotch所有内容。我已经尝试了此方法，但所有内容都在AppBarLayoutThank下运行感谢您的回复，但之后只有一个布局工作，另一个仍然隐藏。您可以将其他高度更改为

android:layout\u height=“match\u parent”

。
