过去一天,我一直在尝试解决UI问题。为了使我的TabLayout透明,我需要将其移动到AppBar布局之外,当我这样做时,它会变得透明,但是在过程中它与工具栏重叠。像这样(请参考图片):
这是我的布局:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:pp="http://schemas.android.com/tools"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<!-- app_bar height @dimen/detail_backdrop_height -->
<android.support.design.widget.AppBarLayout
android:id="@+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:contentScrim="@color/colorPrimary"
app:expandedTitleMarginTop="120dp"
app:expandedTitleGravity="center|bottom"
app:expandedTitleTextAppearance="@style/TransparentText">
<ImageView
android:id="@+id/backdrop"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:alpha="0.4"
app:layout_collapseMode="parallax" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_collapseMode="parallax"
app:layout_anchor="@+id/app_bar">
<de.hdodenhof.circleimageview.CircleImageView
android:id="@+id/cover_image"
android:layout_width="90dp"
android:layout_height="90dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="50dp"
app:civ_border_color="@android:color/black"
app:civ_border_width="1dp" />
<LinearLayout
android:id="@+id/header_text_layout"
android:layout_below="@id/cover_image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/game_title"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Game title"
android:gravity="center"
android:textColor="@android:color/white"
android:textSize="24sp"/>
<TextView
android:id="@+id/developer_txt"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Developer"
android:gravity="center"
android:textColor="@android:color/white"
android:textSize="14sp"/>
<TextView
android:id="@+id/publisher_txt"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Publisher"
android:gravity="center"
android:textColor="@android:color/white"
android:textSize="14sp"/>
</LinearLayout>
</RelativeLayout>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="@android:color/transparent"
app:layout_scrollFlags="scroll|enterAlways"
app:tabGravity="fill"
app:tabMode="fixed"/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<android.support.v4.view.ViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
我想要的是我应用栏下方的透明布局。谢谢!
答案 0 :(得分:0)
要显示背景,您需要在root
的所有TabLayout
上放置透明度。
示例:
<android.support.design.widget.AppBarLayout
android:id="@+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme"
android:background="@android:color/transparent">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme" />
<android.support.design.widget.TabLayout
android:id="@+id/tabLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/transparent">
</android.support.design.widget.TabLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/appBarLayout">
</android.support.v4.view.ViewPager>
否则,您的TabLayout
是透明的,而不是您的AppBarLayout
,因此它们显示的是背景(AppBarLayout
)。
