ListView top highlight on scrolling

Question

The border displays a default color (that's orange on my Nexus S) while scrolling a ListView to the limit. How to change that color?

I really don't know how to explain it. Just look at this picture:

So, how to change the highlight color when the ListView scrolling to the border? using themes or styles

Answer 1

The solution is to use setOverscrollFooter(null) and setOverscrollHeader(null). The documentation is here !

You can also set it directly in the XML :

<ListView android:overScrollMode="never" />

Or specify the footer and the header :

<ListView 
  android:overscrollHeader="@null" 
  android:overscrollFooter="@null" />

N.B. : There is also a property fadingEdge that may interest you.

"Overscroll" methodes are supported starting API level 9

Answer 2

Finally I found the solution.

1. setOverscrollFooter(null) and setOverscrollHeader(null) does not work. At least on 2.3.*. Setting attributes from *.xml doesn't help too.
2. setOverScrollMode(View.OVER_SCROLL_NEVER) causes glitchy scrolling. At least on 2.3.*.

The only solution that really works involves the use of Java Reflection. It works even with ugly custom Samsung listviews with bounce overscroll effect. Here is a snippet:

@Override
protected void onOverScrolled(int scrollX, int scrollY, boolean clampedX, boolean clampedY) {
    //onOverScrolled method must be overrided, or we will see the background of the listview when overscroll fast.
}

private void removeOverscrollEffect() {
    try {
        Class<?> superClass = getClass().getSuperclass().getSuperclass();

        Field field = superClass.getDeclaredField("mEdgeGlowTop");
        field.setAccessible(true);
        Object edgeGlowTop = field.get(this);
        if (edgeGlowTop != null) {
            Class<? extends Object> edgeClass = edgeGlowTop.getClass();
            Field edgeDrawable = edgeClass.getDeclaredField("mEdge");
            edgeDrawable.setAccessible(true);
            edgeDrawable.set(edgeGlowTop, new ColorDrawable(Color.TRANSPARENT));
            Field glowDrawable = edgeClass.getDeclaredField("mGlow");
            glowDrawable.setAccessible(true);
            glowDrawable.set(edgeGlowTop, new ColorDrawable(Color.TRANSPARENT));
            field.set(this, edgeGlowTop);
        }

        Field fieldBottom = superClass.getDeclaredField("mEdgeGlowBottom");
        fieldBottom.setAccessible(true);
        Object edgeGlowBottom = fieldBottom.get(this);
        if (edgeGlowBottom != null) {
            Class<? extends Object> edgeClassBottom = edgeGlowBottom.getClass();
            Field edgeDrawableBottom = edgeClassBottom.getDeclaredField("mEdge");
            edgeDrawableBottom.setAccessible(true);
            edgeDrawableBottom.set(edgeGlowBottom, new ColorDrawable(Color.TRANSPARENT));
            Field glowDrawableBottom = edgeClassBottom.getDeclaredField("mGlow");
            glowDrawableBottom.setAccessible(true);
            glowDrawableBottom.set(edgeGlowBottom, new ColorDrawable(Color.TRANSPARENT));
            fieldBottom.set(this, edgeGlowBottom);
        }
    } catch (Exception e) {
        Log.e(TAG, e.getMessage());
    }
}

I hope this helps.
