But there was a problem in the process of designing the UI. What I wanted to achieve is to click the + sign to enter the album like WeChat. After selecting the picture, the selected picture is displayed on the page. After selecting it, I upload it. I first borrowed the first one. The UI design of the blog, but in the process of writing the Android xml code, it prompts that android.support.v7.widget.RecyclerView has not been successfully imported. It has been a long time to check and has not solved the problem. It is too late in time. , And found the second one. For the time being, I copied it myself according to his writing, mainly to see the effect of the page, as shown below:
The code is not pasted, which is basically the same as the brief book. Today's learning self-evaluation is unsuccessful. Tomorrow, at least the picture upload function must be completed. This is a dead order.
