我有一个布局为:
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_height="56dp"
android:layout_width="match_parent"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:layout_collapseMode="pin"/>
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="wrap_content"
app:tabIndicatorColor="@color/indicator"
app:tabMode="scrollable"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
在
ViewPager
中加载的片段具有以下布局:<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/refresh_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/gridView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="10dp"
android:scrollbars="vertical" />
</android.support.v4.widget.SwipeRefreshLayout>
<android.support.design.widget.FloatingActionButton
android:id="@+id/download_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="16dp"
android:layout_marginLeft="16dp"
android:src="@drawable/ic_btn_download" />
</RelativeLayout>
如何将浮动操作按钮(FloatingActionButton
)在片段内固定位置(防止滚动)?
请注意,我无法将 FloatingActionButton
移动到活动布局中。
