如何显示水平 Recyclerview - 显示水平项目时遇到问题

Question

我想在 recyclerview 中显示水平项目，但我已经尝试过，但没有成功，只显示具有放大宽度的水平项目。

在Android Studio中按我想要的方式显示

但在我的移动设备中运行时，告诉我

这些项目是宽度换行的，但其他项目在滚动后出现，与我的上一个项目分开。

这是我的代码。

Answer 1

如果其他人有这个问题，我修复了在片段类中添加这一行。rlista.setHasFixedSize(true);

Answer 2

在您的 recyclerview 项目布局中，将这 2 个文本视图 [tnombre 和 thorarios] 的宽度更新为 wrap_content<LinearLayout&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_gravity="center_vertical"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_marginLeft="5dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:orientation="vertical">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <TextView&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/tnombre"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:ellipsize="end"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:inputType="textMultiLine"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:lines="1"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:textAppearance="@style/TextAppearance.AppCompat.Medium"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:textSize="12sp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:textStyle="bold"></TextView>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <TextView&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/thorarios"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_gravity="center_vertical"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:textAppearance="@style/TextAppearance.AppCompat.Small"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:textColor="@color/colorPrimary"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:textSize="10sp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:visibility="gone"></TextView>&nbsp; &nbsp; &nbsp; &nbsp; </LinearLayout>

Answer 3

我想你只需在你的类适配器中添加notifyDataSetChangedpublic rutaSelAdapter(List<Ruta> l, onItemClick onclick) {&nbsp; &nbsp; &nbsp; &nbsp; lista = l;&nbsp; &nbsp; &nbsp; &nbsp; this.onItemClick = onclick;&nbsp; &nbsp; &nbsp; &nbsp; if (l.size() > 0)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; setSelectedItem(l.get(0));&nbsp; &nbsp; &nbsp; &nbsp; notifyDataSetChanged();&nbsp; &nbsp; }
