Android TextView with scrollbars and maxHeight

android

提问by alex2k8

I need to set the TextView maximum height (either using maxHeight or maxLines). And if there are more lines of text the scrollbars should be shown. What markup should I use for this?

我需要设置 TextView 最大高度(使用 maxHeight 或 maxLines)。如果有更多行文本,则应显示滚动条。我应该为此使用什么标记?

Initial idea was to wrap TextView with ScrollView, but ScrollView has no maxHeight attribute.

最初的想法是用 ScrollView 包裹 TextView,但 ScrollView 没有 maxHeight 属性。

Layout:

布局:

<TextView
    android:id="@+id/text_view"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:singleLine="false"
    android:maxLines="3"
    android:scrollbars="vertical"
    android:textColor="@android:color/secondary_text_dark_nodisable"
    >
</TextView>

Code:

代码:

TextView textView = (TextView)findViewById(R.id.text_view);
textView.setMovementMethod(ScrollingMovementMethod.getInstance());

Note:

笔记:

The android:textColor="@android:color/secondary_text_dark_nodisable" is used to avoid text fade out when textView is touched.

android:textColor="@android:color/secondary_text_dark_nodisable" 用于避免触摸 textView 时文本淡出。
