Android zxing二维码扫描适应各种分辨率

在使用zxing二维码时，发现有时候出现拉伸的现象，不能很好的适应各种分辨率，经过测试，只要在CameraManager.java中，修改一下如下方法即可，代码如下：

public synchronized Rect getFramingRect() {
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 * 0.6);
int height = (int) (width * 0.9);

int leftOffset = (screenResolution.x - width) / 2;
int topOffset = (screenResolution.y - height) / 4;
framingRect = new Rect(leftOffset, topOffset, leftOffset + width,
topOffset + height);
Log.d(TAG, "Calculated framing rect: " + framingRect);
}
return framingRect;
}
