本人在用UiAutomator做测试的时候，经常会遇到一些控件因为不同的条件显示不同的颜色，在学习了UiAutomator图像处理之后，自己尝试写了一个方法来处理不同颜色控件的区分。分享代码供大家参考。

	//根据颜色判断状态
	public boolean isBlue(UiObject uiObject) throws UiObjectNotFoundException {
		screenShot("test");//截图
		String path = "/mnt/sdcard/123/test.png";
		Bitmap bitmap = BitmapFactory.decodeFile(path);//新建并实例化bitmap对象
		Rect rect = uiObject.getVisibleBounds();
		int x = rect.left;
		int xx = rect.right;
		int y = rect.top;
		int yy = rect.bottom;
		List<Integer> blueColor = new ArrayList<Integer>();
		for (int i = x; i < xx; i++) {
			for (int k = y;k < yy;k++) {
				int color = bitmap.getPixel(i, k);//获取坐标点像素颜色
				int red = Color.blue(color);
				blueColor.add(red);
			}
		}
		int sum = 0;
		for (int i = 0;i<blueColor.size();i++) {
			sum += blueColor.get(i);
		}
//		output(sum/blueColor.size());
		return sum/blueColor.size() > 200?true:false;
	}

下面是在选择判定值的过程中快速获取某点颜色值的方法：

	public int getRedPixel(int x, int y) {
		screenShot("test");//截图
		String path = "/mnt/sdcard/123/test.png";
		Bitmap bitmap = BitmapFactory.decodeFile(path);//新建并实例化bitmap对象
		int color = bitmap.getPixel(x, y);//获取坐标点像素颜色
//		output(color);//输出颜色值
		int red = Color.red(color);
		return red;
	}
	public int getGreenPixel(int x, int y) {
		screenShot("test");//截图
		String path = "/mnt/sdcard/123/test.png";
		Bitmap bitmap = BitmapFactory.decodeFile(path);//新建并实例化bitmap对象
		int color = bitmap.getPixel(x, y);//获取坐标点像素颜色
//		output(color);//输出颜色值
		int green = Color.green(color);
		return green;
	}
	public int getBluePixel(int x, int y) {
		screenShot("test");//截图
		String path = "/mnt/sdcard/123/test.png";
		Bitmap bitmap = BitmapFactory.decodeFile(path);//新建并实例化bitmap对象
		int color = bitmap.getPixel(x, y);//获取坐标点像素颜色
//		output(color);//输出颜色值
		int blue = Color.blue(color);
		return blue;
	}

public int[] getRGBcolorPixel(int x, int y) {
		screenShot("testDemo");
		String path = "/mnt/sdcard/123/testDemo.png";
		Bitmap bitmap = BitmapFactory.decodeFile(path);
		int color = bitmap.getPixel(x, y);
		int red = Color.red(color);
		int green = Color.green(color);
		int blue = Color.blue(color);
		int[] rgb = {red, green, blue};
		return rgb;
	}
