Android 技术小结（009）—— 设置相机拍照尺寸为最小支持尺寸

        // 获取屏幕信息        WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);        Display display = wm.getDefaultDisplay();        // 初始化相机        Camera camera = Camera.open();        Camera.Parameters parameters = camera.getParameters();        parameters.setPreviewSize(display.getWidth(), display.getHeight());        List<Camera.Size> pszize = parameters.getSupportedPictureSizes();        if (null != pszize && 0 < pszize.size()) {            int height[] = new int[pszize.size()];            Map<Integer, Integer> map = new HashMap<Integer, Integer>();            for (int i = 0; i < pszize.size(); i++) {                Camera.Size size = (Camera.Size) pszize.get(i);                int sizeheight = size.height;                int sizewidth = size.width;                height[i] = sizeheight;                map.put(sizeheight, sizewidth);            }            Arrays.sort(height);            parameters.setPictureSize(map.get(height[0]), height[0]);        } else {            parameters.setPictureSize(display.getWidth(), display.getHeight());        }
