Question

I’m trying to use a NinePatch image, stretched horizontally.

I haven’t used NinePatch much, but do have other NinePatches images working in other areas (e.g., as background of of Views with content), as expected.

I’ve attached a simplified version of what I’m experiencing. Basically I want the dot to tile the center pixel horizontally. The image will only ever expand horizontally. It does not contain any other views.

I first tried setting just a single-pixel vertical path, then added a single-pixel horizontal path as well. No difference. In the preview panel of the NinePatch tool, it appears fine.

It’s being used in a RelativeLayout, per the code sample below. I’ve included lines that are commented out as other settings I’ve tried.

track = new ImageView(context);
track.setScaleType(ScaleType.FIT_XY);
//track.setScaleType(ScaleType.FIT_CENTER);
track.setBackgroundResource(R.drawable.bg_track);
//track.setImageResource(R.drawable.bg_track);

LayoutParams trackLayout = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
//LayoutParams trackLayout = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
trackLayout.addRule(RelativeLayout.CENTER_VERTICAL);
trackLayout.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
trackLayout.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);

addView(track, trackLayout);

I’m sure I’m missing something simple, but can’t figure it out.

Any insights are appreciated.

TYIA.
