【问题描述】:
我正在使用 recyclerview 来显示项目列表,并且约束布局是父视图。布局如下图所示:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<!-- Load the toolbar here -->
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:minHeight="?android:attr/actionBarSize"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:background="@color/colorPrimary"/>
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:visibility="visible"
app:layout_constraintTop_toBottomOf="@+id/toolbar" />
<ImageView
android:id="@+id/imageViewContent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintTop_toBottomOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintBottom_toTopOf="parent"
android:visibility="gone"
android:src="@drawable/empty_category"/>
<TextView
android:id="@+id/textViewContent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:gravity="center"
android:text="Empty Category"
android:textStyle="bold"
android:textColor="@color/colorPrimary"
android:textAppearance="@style/TextAppearance.AppCompat.Large"
android:visibility="gone"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="@+id/imageViewContent" />
</android.support.constraint.ConstraintLayout>
The adapter layout for each row is presented below:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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">
<FrameLayout
android:id="@+id/framelayoutImage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="@id/buttonCart"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp">
<ImageView
android:id="@+id/imageViewCoverArt"
android:layout_width="match_parent"
android:layout_height="200dp"
android:scaleType="center" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#59000000"
android:orientation="vertical">
<TextView
android:id="@+id/textViewPrice"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom|left"
android:layout_marginLeft="10dp"
android:clickable="false"
android:text="$220"
android:textAppearance="@style/TextAppearance.AppCompat.Medium"
android:textColor="@android:color/white"
android:textStyle="bold" />
<TextView
android:id="@+id/textViewDetails"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom|left"
android:layout_marginLeft="10dp"
android:layout_marginTop="8dp"
android:ellipsize="end"
android:maxLength="17"
android:maxLines="1"
android:text="Lorem ipsum dolor sit amet, consecte"
android:textAppearance="@style/TextAppearance.AppCompat.Medium"
android:textColor="@android:color/white" />
</LinearLayout>
</FrameLayout>
<Button
android:id="@+id/buttonCart"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="8dp"
android:background="@drawable/buttonshape"
android:text="Add to Cart"
android:textAppearance="@style/TextAppearance.AppCompat.Small"
android:textColor="@android:color/white"
android:textStyle="bold"
/>
</LinearLayout>
运行我的应用程序后,布局如下图所示:
我尝试在回收视图中添加底部边距,但这并没有解决问题。我使用以下链接作为参考:RecyclerView is cutting off the last item、RecyclerView cutting off last item 并尝试在没有运气的情况下进行这些更改
