Android TextView with scrollbars and maxHeight

2020-01-31 02:56发布

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?

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

Layout:

<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:

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

Note:

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