在nestedscrollview中的coordinatorlayout中,我有相关性和relativelayout内部我有textView。当NestedScrollview触摸工具栏底部部分时,它将滚动文本视图内容滚动到完整的Relativelayout卡。
这是我的代码。
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@+id/product_bottom_layout"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="192dp"
android:fitsSystemWindows="true"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="@color/white"
app:expandedTitleTextAppearance="@style/TransparentText"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:titleEnabled="false">
<ImageView
android:id="@+id/product_img"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:fitsSystemWindows="true"
app:imageUrl="@{viewModel.imageUrl}"
android:scaleType="centerInside"
app:layout_collapseMode="parallax"
android:background="@color/white"/>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
android:gravity="center_vertical"
android:minHeight="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:theme="@style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="@dimen/dimen_60"
android:layout_marginLeft="@dimen/dimen_7"
android:layout_marginRight="@dimen/dimen_7"
android:layout_marginTop="@dimen/dimen_7"
android:background="@drawable/card_bg"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/dimen_3"
android:layout_marginRight="@dimen/dimen_3"
android:layout_marginTop="@dimen/dimen_3"
android:background="@color/white">
<app.com.test.Views.CustomTextView
android:id="@+id/description_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/dimen_12"
android:layout_marginRight="@dimen/dimen_12"
android:layout_marginTop="@dimen/dimen_12"
android:lineSpacingExtra="8dp"
android:textColor="@color/title_color"
android:textSize="14sp"/>
</RelativeLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
我得到了解决方案。它实际上是NestedScrollview不会滚动其孩子,它实际上滚动了孩子的内容,因此要滚动整个布局而不是文本,我们需要添加更多的父母布局:
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="fill_vertical"
android:layout_marginBottom="@dimen/dimen_60"
android:scrollbars="none"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="@dimen/dimen_10"
android:background="@color/bg_color"
android:orientation="vertical"
android:padding="@dimen/dimen_6">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="@dimen/dimen_10"
android:layout_marginLeft="@dimen/dimen_3"
android:layout_marginRight="@dimen/dimen_3"
android:layout_marginTop="@dimen/dimen_3"
android:background="@drawable/card_bg">
<app.com.test.Views.CustomTextView
android:id="@+id/product_title_txt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/dimen_12"
android:layout_marginRight="@dimen/dimen_12"
android:layout_marginTop="@dimen/dimen_12"
android:text=""
/>
</RelativeLayout>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
