在自定义回收器适配器中滚动文本视图

Question

我正在使用带有自定义适配器的自定义RecyclerView。在适配器模型 XML 中有一个具有固定高度和宽度的文本视图，我需要在文本视图中滚动文本。滚动文本视图时不要滚动整个RecyclerView。

Answer 1

你可以尝试用NestedScrollView 包裹你的TextView

<android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
    </android.support.v4.widget.NestedScrollView>

Answer 2

RecyclerView 不是为此而生的。你想做的是这样的

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="50dp">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="This is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\nThis is a very very longs text\n"/>
</ScrollView>

如果您坚持在 RCV 中使用这样的 TextView - 请重新考虑您的设计理念。垂直内垂直滚动是一个可怕的想法。
