根据这个相关问题Make drawerlayout inside fragment full screen height 我不确定是对还是错，但似乎片段总是不是全屏，即它只复制内容的布局属性并使用它，这就是为什么你可以在一个布局中有两个或多个片段。
现在我遇到了将Drawerlayout的高度设置为match_parent的问题，我得到的错误的完整堆栈粘贴在下面。我尝试了所有我知道的方法来强制设置布局参数，但它只是不起作用，如果我给布局一个特定的dp，如500dp，那么它将起作用。

我决定通过扩展DrawerLayout本身来创建一个自定义的DrawerLayout，并且做了什么，但重复了DrawerLayout中的方法。但我唯一做的就是在 DrawerLayout 中@ 覆盖 onMeasure 方法。
下面是我的Custom DrawerLayout以及我在layout ::
中如何调用它public class WhalesDrawerLayout extends DrawerLayout {
public WhalesDrawerLayout(Context context) {
super(context);
}
public WhalesDrawerLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public WhalesDrawerLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
widthMeasureSpec = MeasureSpec.makeMeasureSpec(
MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.EXACTLY);
heightMeasureSpec = MeasureSpec.makeMeasureSpec(
MeasureSpec.getSize(heightMeasureSpec), MeasureSpec.EXACTLY);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
在您的布局中应该像这样调用：
<whalescorp.projectname.packagename.WhalesDrawerLayout
android:id="@+id/drawer"
android:fitsSystemWindows="true"
tools:openDrawer="start"
android:layout_height="match_parent"
android:layout_width="match_parent">
</whalescorp.projectname.packagename.WhalesDrawerLayout>
通过在activity.xml中键入类名，它会带来建议，您也可以轻松地获得它，同时您需要在项目工作之前重建项目，并且可以在代码中调用它这个::
final WhalesDrawerLayout drawerLayout = l.findViewById(R.id.drawer);

由于新的ConstraintLayout，也可能发生这种情况。确保抽屉布局不在ConstraintLayout的层次结构中。
在Android上，这是一个非常愚蠢的错误。我会尝试为它提交一个错误。
