使用可影响布局的图层列表可设置标签的背景

Question

I'm trying to set a custom background for the tabs in my TabWidget. They're pretty much all just a bunch of rectangle shape gradients, but I found out that by setting the background drawables, it removes the default divider between each tab. To remedy this, I used a layer-list drawable to layer a divider on top of the tabs. However, now, it's affecting the layout of the tab itself, causing the image and text label to move apart.

Intended result
What I get by using a layer-list for the background

I'm just using this to setup the backgrounds:

TabWidget tw = mTabHost.getTabWidget(); 
for (int i = 0; i < tw.getChildCount(); i++) { 
    View v = tw.getChildAt(i); 
    v.setBackgroundDrawable(getResources().getDrawable (R.drawable.tab_background)); 
}

Any clues as to why this is happenings, or suggestions on what else I can do instead?

Answer 1

It seems that using the layer-list as a background reset the all of the paddings within the view to 0. A bit non-sensical, considering a background drawable conceptually shouldn't affect any of this stuff, but whatever, I suppose. Saving the previous paddings and setting them back to what they were before fixes the problem.
