Prevent scrollbar from hiding on froyo

Starting with 2.2, scrollbars wo开发者_高级运维uld disappear once the scrolling has stopped.

Is there a way to make them always visible like before?

A helper method:

public static void disableScrollbarFading(View view) {
    try {
        Method setScrollbarFadingEnabled = View.class.getDeclaredMethod(
                "setScrollbarFadingEnabled", boolean.class);
        setScrollbarFadingEnabled.setAccessible(true);
        setScrollbarFadingEnabled.invoke(view, false);
    } catch (Exception e) {
        // OK, API level < 5
    }
}

What about View.setScrollbarFadingEnabled(boolean fadeScrollbars)? This is available since API level 5.

You can also set this in the xml with android:fadeScrollbars="false".
