Is it possible to change the colour of the FadingEdge of a Listview?
I want to give the effect that the ListView has faded from whatever is around it. By default it is set to what开发者_Python百科ever colour your ListView is. I can adjust the orientation of the FadingEdge and the size of the FadingEdge but not the colour. Is it possible?
You'll need to create a new class that extends ListView.
package com.mypackage;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.ListView;
public class ColorFadeListView extends ListView
{
// fade to green by default
private static int mFadeColor = 0xFF00FF00;
public ColorFadeListView(Context context, AttributeSet attrs)
{
this(context, attrs,0);
}
public ColorFadeListView(Context context, AttributeSet attrs, int defStyle)
{
super(context,attrs,defStyle);
setFadingEdgeLength(30);
setVerticalFadingEdgeEnabled(true);
}
@Override
public int getSolidColor()
{
return mFadeColor;
}
public void setFadeColor( int fadeColor )
{
mFadeColor = fadeColor;
}
public int getFadeColor()
{
return mFadeColor;
}
}
You can use this list view identically to a normal ListView
(though you'll have to cast it properly to use the fadeColor accessor methods). In your XML, instead of defining an object as <ListView android:properties.../>
define it as <com.mypackage.ColorFadeListView android:properties.../>
Yes you can !
setCacheColorHint(Color.WHITE);
You can try this (it's a hack, I know):
int glowDrawableId = context.getResources().getIdentifier("overscroll_glow", "drawable", "android");
Drawable androidGlow = context.getResources().getDrawable(glowDrawableId);
androidGlow.setColorFilter(brandColor, PorterDuff.Mode.MULTIPLY);
I took advantage of the fact that the glow effect is actually a shared Drawable and applied a filter on it: http://evendanan.net/android/branding/2013/12/09/branding-edge-effect/
