水平缩放NinePatch图像（无子，在RelativeLayout的） [英] Scaling NinePatch image horizontally (without children, in a RelativeLayout)

问题描述

我试图用一个形象NinePatch，横向拉长。

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

我没有用太多NinePatch，但在其他方面工作的其他NinePatches图像（例如，作为与内容的看法的背景），符合市场预期。

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.

我已经附加了什么我遇到的简化版本。基本上我想要的网点平铺中心像素水平。该图像将只水平扩展。它不包含任何其他意见。

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.

我第一次尝试设置只是一个单一像素的垂直路径，然后加一个单像素水平的路径为好。没有不同。在NinePatch工具的preVIEW面板，看起来很好。

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.

这是在一个RelativeLayout的被使用，每低于code样品。我已经包含了被注释掉，因为我已经尝试过其他的设置行。

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);

我敢肯定，我失去了一些东西简单，但不能看着办吧。

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

任何见解是AP preciated。

Any insights are appreciated.

TYIA。
