创建一个九补丁图像code [英] Create a nine patch image with code

问题描述

我想以编程方式创建9片图像。我曾尝试<一href="http://stackoverflow.com/questions/5079868/create-a-ninepatch-ninepatchdrawable-in-runtime/14061128#14061128">Griffey's方法，但似乎无法得到它的工作。有一个关于如何使用类的信息非常少。我相信我导入位图不正确。如果有人知道如何得到这个工作，或者知道一个更好的办法，我会非常AP preciate你的帮助。

I am trying to create nine patch images programmatically. I have tried Griffey's approach but can't seem to get it to work. There is very little information about how to use the class. I believe I am importing the bitmap incorrectly. If anyone knows how to get this to work or knows a better way, I'd greatly appreciate your help.

我的code：

// Dynamically create the 9patch image and apply it to a LinearLayout
LinearLayout llcode = (LinearLayout) findViewById(R.id.llcode);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.white_button);
Drawable np = NinePatchBitmapFactory.createNinePathWithCapInsets(getResources(), bitmap, 15, 15, 16, 16, null);

llcode.setBackgroundDrawable(np);

// The following code using the actual 9patch image: white_button_np.9.png
LinearLayout llxml = (LinearLayout) findViewById(R.id.llxml);
llxml.setBackgroundDrawable(getResources().getDrawable(R.drawable.white_button_np));

该屏幕截图显示在顶部，并使用在底部的机器人工具的典型9patch方法的编程方法。

This screenshot shows the programmatic method on top and the typical 9patch method using the android tool on bottom.

在它原始图像会转换为一个9patch。

The original image before it's converted to a 9patch.
