zxing适应各种分辨率

因为zxing实现扫描二维码的界面是由自己绘制的，发现在不同分辨率上显示的效果不一样，有的根本就重叠了，然后在网上搜索了一下，发现一篇不错的文章也讲到这种问题，分享一下http://blog.csdn.net/jdsjlzx/article/details/46429043，下边是我根据这篇博客修改过的效果，根据自己的项目，确定不同的宽高之类的值就可以了

public Rect getFramingRect() {
 /* Point screenResolution = configManager.getScreenResolution();
  if (framingRect == null) {
    if (camera == null) {
      return null;
    }
    int width = screenResolution.x * 3 / 4;
    if (width < MIN_FRAME_WIDTH) {
      width = MIN_FRAME_WIDTH;
    } else if (width > MAX_FRAME_WIDTH) {
      width = MAX_FRAME_WIDTH;
    }
    int height = screenResolution.y * 3 / 4;
    if (height < MIN_FRAME_HEIGHT) {
      height = MIN_FRAME_HEIGHT;
    } else if (height > MAX_FRAME_HEIGHT) {
      height = MAX_FRAME_HEIGHT;
    }
    int leftOffset = (screenResolution.x - width) / 2;
    int topOffset = (screenResolution.y - height) / 2;
    framingRect = new Rect(leftOffset, topOffset, leftOffset + width, topOffset + height);
    Log.d(TAG, "Calculated framing rect: " + framingRect);
  }*/
  if (framingRect == null) {
    if (camera == null) {
      return null;
    }
    Point screenResolution = configManager.getScreenResolution();
    if (screenResolution == null) {
      // Called early, before init even finished
      return null;
    }

    // int width = findDesiredDimensionInRange(screenResolution.x,
    // MIN_FRAME_WIDTH, MAX_FRAME_WIDTH);
    // int height = findDesiredDimensionInRange(screenResolution.y,
    // MIN_FRAME_HEIGHT, MAX_FRAME_HEIGHT);

          /* 扫描框修改 */
    DisplayMetrics metrics = context.getResources().getDisplayMetrics();
int width = (int) (metrics.widthPixels * 0.7);
int height = (int) (width );

    int leftOffset = (screenResolution.x - width) / 2;    int topOffset = (screenResolution.y - height) / 3;    framingRect = new Rect(leftOffset, topOffset, leftOffset + width,            topOffset + height);    Log.d(TAG, "Calculated framing rect: " + framingRect);  }  return framingRect;}
 
今天的文章zxing适应各种分辨率分享到此就结束了，感谢您的阅读。
