android - 处理 R 到 L 语言的水平 ScrollView

Question

如何处理 R 到 L 语言的水平 ScrollView 。 我在水平 ScrollView 中添加 24 线性布局。它适用于 L 到 R，但不适用于 R 到 L 语言。 XML 代码:

    <LinearLayout
        android:id="@+id/linearLayoutTimeAmPm"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >

        <include
            android:id="@+id/linearLayout0Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout1Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout2Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout3Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout4Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout5Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout6Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout7Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout8Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout9Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout10Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout11Am"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout0Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout1Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout2Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout3Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout4Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout5Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout6Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout7Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout8Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout9Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout10Pm"
            layout="@layout/include_time_textview" />

        <include
            android:id="@+id/linearLayout11Pm"
            layout="@layout/include_time_textview" />
    </LinearLayout>
</HorizontalScrollView>

这是在 L 到 R 语言中工作。但是在 R 到 L 语言中，它显示为

它是从左向右滚动，但是在 ScrollView 中只添加了 4 个布局。从左向右滚动后 --->

我想在水平 ScrollView 中添加24个布局， ScrollView 方向应从右到左(选择L语言时)。

我在使用 api 17 的设备上遇到了这个问题。我不小心尝试了这个并且对我来说效果很好: 我只是将 android:layoutDirection="ltr" 放在 Horizo​​ntalScrollView 标签中，并将 android:layoutDirection="rtl" 用于它的每个子项(您的 LinearLayout)
