zxing 二维码框的大小怎么设置

Answer 1

private static final int MIN_FRAME_HEIGHT = 240;//240
private static final int MAX_FRAME_WIDTH = 480;//480
private static final int MAX_FRAME_HEIGHT = 480;//360

CameraManager类的getFramingRect方法
public Rect getFramingRect() {
Point screenResolution = configManager.getScreenResolution();
if (framingRect == null) {
if (camera == null) {
return null;
}
int width = screenResolution.x * 2 / 3;//设定框框宽度大小
if (width < MIN_FRAME_WIDTH) {
width = MIN_FRAME_WIDTH;
} else if (width > MAX_FRAME_WIDTH) {
width = MAX_FRAME_WIDTH;
}
int height = screenResolution.y * 2/ 4;//设定框框高度大小
if (height < MIN_FRAME_HEIGHT) {
height = MIN_FRAME_HEIGHT;
} else if (height > MAX_FRAME_HEIGHT) {
height = MAX_FRAME_HEIGHT;
