如何在 Android 中创建水平和垂直滚动的列表视图？

Question

我需要一个可以在垂直和水平方向滚动的列表视图。

<HorizontalScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:overScrollMode="always"
    android:scrollbarAlwaysDrawVerticalTrack="true">

    <ListView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:drawSelectorOnTop="true"
        android:scrollbars="vertical|horizontal">

    </ListView>
</HorizontalScrollView>

这是我的代码，但它只制作水平列表视图。

Answer 1

首先。不要使用列表视图。而是使用带有自定义 LayoutManager 的 RecyclerView。

作为解决方案，试试这个。 Create a RecyclerView with both horizontal and vertical scrolling

Answer 2

在水平滚动视图内部创建列表视图，骨架如下

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="vertical"
    android:fillViewport="true">

    <HorizontalScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fillViewport="true">

        <ListView
            android:id="@+id/simpleListView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:divider="@color/material_blue_grey_800"
            android:dividerHeight="1dp" />

    </HorizontalScrollView>
</ScrollView>

创建 item_list 文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="20dp"
    android:orientation="horizontal">
<ImageView
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:src="@drawable/ic_launcher_background"
    android:text="btn"/>
    <TextView
        android:id="@+id/textView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:padding="10dp"
        android:textColor="#000000" />
</LinearLayout>

Java 代码：

public class MainActivity extends AppCompatActivity {

    ListView simpleList;
    String myList[] = {"Lorem Ipsum is simply dummy text of the printing and typesetting industry.
