嗨我正在从json检索图像和文本，基于使用回收视图显示视图的值。如果数据少于10日期，所有工作都会正常，如果超过 10个图像在回收站视图中只显示一次。在向下滚动并滚动图像消失后，不知道我在哪里做错了。图像在recyclerview的imageview中只显示一次
这是我的代码
jsondata
"DATA":[
{
"ID":"82",
"MSG":"",
"IMAGE":"http://14.18.19.15/data/chat_img/20160308102624439533297.jpg",
"TYPE":"1",
"STATUS":"0",
"DATE":"2016-03-08 10:26:24"
},
{
"ID":"81",
"MSG":"saggergergergaskfasjdfahsdfalshdfaldfafdjkahsdfkjahlfdkjahfls",
"IMAGE":"",
"TYPE":"1",
"STATUS":"0",
"DATE":"2016-03-08 10:25:40"
},
{
"ID":"80",
"MSG":"Hi",
"IMAGE":"",
"TYPE":"2",
"STATUS":"0",
"DATE":"2016-03-07 13:24:00"
},....

你为什么使用holder.imageView.setVisibility（View.GONE）; –
holder.imageView.setVisibility（View.Visible）;在第一条语句上面的try语句下面添加下面这行，检查它是否有效 – Sayyaf
