列表项视图未正确显示在线性 RecyclerView 中
List item views not correctly appearing in Linear RecyclerView
您好,我有一个水平的 recyclerView,它应该显示一张图片并在其下方显示一个名称。我无法让它工作,因为图像视图显示不同大小,即使它们具有固定尺寸,并且下面的文本不可见或奇怪地放置。以下是模拟器和我的 phone.

对于水平回收器视图,您可以执行如下操作:
LinearLayoutManager horizontalLayoutManagaer
= new LinearLayoutManager(MainActivity.this, LinearLayoutManager.HORIZONTAL, false);
cast_recyclerView.setLayoutManager(horizontalLayoutManagaer);
cast_recyclerView.setAdapter(horizontalAdapter);
并将您的 list_item.xml 更改为以下内容:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="wrap_content"
android:background="#E0E0E0"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/profile_pic"
tools:background="@android:color/black"
tools:src="@drawable/test"
android:layout_width="100dp"
android:layout_height="135dp"
android:scaleType="centerCrop"/>
<TextView
android:layout_marginTop="5dp"
android:layout_gravity="center"
android:id="@+id/actor_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:maxLines="1"
android:ellipsize="end"
android:textColor="@android:color/black"
android:textStyle="bold"
tools:text="The name of an actor"
android:textSize="12sp"/>
<TextView
android:id="@+id/actor_role"
android:layout_gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:maxLines="1"
android:ellipsize="end"
tools:text="The character playd by that actor"
android:textSize="12sp"/>
</LinearLayout>
同时将您的 cardView 中的 recyclerview 更改为以下内容:
<android.support.v7.widget.RecyclerView
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginBottom="8dp"
android:id="@+id/cast_recyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
