在Android中创建二维滚动视图的正确方法是什么?

标签: android layout scrollview

我需要创建一个二维视图,支持每行的垂直滚动和水平滚动,非常类似于Google的画廊设计或Netflix的工作方式。我在一些帖子中讨论了使用嵌套滚动视图等的最佳做法和预订,但其中大多数都是非常老的帖子。

鉴于当前版本的Android,实现此类行为的正确方法是什么?

这是我目前使用的代码:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"    
    android:paddingLeft="@dimen/activity_horizontal_margin"
    tools:context="com.example.culami.RecipeDashboardActivity"
    android:orientation="vertical"
    android:background="#2E2E2E"
     >

    <!-- Parent Linear Layout -->
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center|left"
        android:orientation="vertical">


        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="15dp"
            android:text="@string/recipeDashLabel1"
            android:gravity="left"
            android:textSize="24sp"
            android:padding="5dp"
            android:textColor="#ffffff" />

我需要能够将每行LinearLayout中的三个虚拟图像替换为适用于多个图像的水平可滚动视图。 我怎样才能做到这一点?

Lucas Rocha结帐TwoWay-View。您可以选择滚动2维,或将其固定为1维(水平/垂直)。

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
        <org.lucasr.twowayview.TwoWayView
            android:orientation="horizontal"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>
        <!-- some more horizontal TwoWayView here -->
    </LinearLayout>
</ScrollView>
