我正在尝试实现以下目标
我正在尝试建立一个连接3个片段的活动。顶部片段包含一个搜索栏(EditText
),中间片段包含一个横幅滑块(ViewPager
),底部片段包含一个GridView
,动态加载了n
个项目。我想使中间和底部的片段垂直滚动,同时固定顶部的片段。但是,当高度设置为wrap_content
时,“网格”视图将在其内部滚动。
如果GridView
的高度固定,则说明其正常工作。但是我不能给它一个固定的高度,因为它的内容是动态加载的。

您可以在ViewPager和Gridview之外使用nestedScrollView。
将回收站视图设置为 setNestedScrollingEnable(false)。
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
<GridView
android:layout_width="match_parent"
android:layout_height="match_parent">
</GridView>
</android.support.v4.widget.NestedScrollView>

Try using `Constraint Layout` for whole layout, `autocomplete text view` for search bar, `viewpager` for banners, recycler view for showing the loaded items.
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<AutoCompleteTextView
android:id="@+id/search"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toTopOf="parent"/>
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent">
</android.support.v7.widget.RecyclerView>
</android.support.constraint.ConstraintLayout>
**根据用户界面设置边距
Set your layout manager as Gridlayout manager for recycler view as below:
recyclerview.layoutManager = GridLayoutManager(this, 2, OrientationHelper.VERTICAL, false)
希望它能正常工作。让我知道是否有任何问题。
