这里基本上我试图让我在向上滚动数据时工具栏崩溃的CoordinatorLayout行为。但是,工具栏已完全冻结且未折叠。此外,我试图在工具栏上显示未显示的数据,如下所示。
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@android:color/background_light"
android:fitsSystemWindows="true"
>
<android.support.design.widget.AppBarLayout
android:id="@+id/main.appbar"
android:layout_width="match_parent"
android:layout_height="300dp"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true"
>
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/toolbar_container"
android:layout_width="match_parent"
android:layout_height="112dp"
android:background="?colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
android:fitsSystemWindows="true"

<ImageView

android:layout_height="wrap_content"

app:layout_collapseMode="parallax"
/>
<android.support.v7.widget.Toolbar

app:layout_collapseMode="pin"

</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_refresh_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:scrollbarStyle="outsideOverlay"
android:paddingTop="116dp"
android:paddingLeft="@dimen/list_side_margin"
android:paddingRight="@dimen/list_side_margin"
android:paddingBottom="28dp" />
</android.support.v4.widget.SwipeRefreshLayout>
</android.support.design.widget.CoordinatorLayout>
答案 0 :(得分:0)
首先,您需要在swiperefreshlayout中使用此行。
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_refresh_layout"
android:layout_width="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:layout_height="match_parent">
对于显示名称,请检查您的AndroidMenifest文件。您可能错过了添加标签属性
<activity
android:name=".MainActivity"
android:label="Main Activity"
android:screenOrientation="portrait"/>
