android 大图预览

导入moudle ，

 implementation 'com.ycjiang:imgepreviewlibrary:1.1.3'

然后在图片点击事件添加以下代码

  Intent intent = new Intent(WXJiLuDetailActivity.this, EnlargeImageDetailActivity.class);
                    intent.putExtra(CommonUtils.SpaceImageDetail.IMAGEURL, HttpConfig.IMG_URL + "/" + imglist.get(position));//传入 图片的URL

                    int[] location = new int[2];
                    view.getLocationOnScreen(location);//view 就是所点击的ImageView
                    intent.putExtra(CommonUtils.SpaceImageDetail.LOCATIONX, location[0]);
                    intent.putExtra(CommonUtils.SpaceImageDetail.LOCATIONY, location[1]);

                    intent.putExtra(CommonUtils.SpaceImageDetail.WIDTH, view.getWidth());
                    intent.putExtra(CommonUtils.SpaceImageDetail.HEIGHT, view.getHeight());
                    startActivity(intent);
                    overridePendingTransition(0, 0);
