Question

我的主要布局有CoordinatorLayout，其中包含AppBarLayout，CollapsingToolbarLayout，Toolbar和TabLayout。

但是，工具栏不显示阴影。

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

我的布局有什么问题？

尝试这个我也有同样的问题，它对我有用

  final AppBarLayout.LayoutParams params = (AppBarLayout.LayoutParams)
            toolbar.getLayoutParams();
    params.setScrollFlags(0);
    toolbar.setLayoutParams(params);

Android工具栏没有海拔
