how to render view in android based on the data received from server?

Question

I am new to android development. I am trying to build basic shopping cart. I want to know how can I render view based on the data (product details) received from server. Because I will make a call to server in AsyncTask and I will have to wait for the data and then only I will be able to render them. So, I couldn't be able to figure out how would I manage it? Any help is appreciated.

Answer 1

Use a broadcastreceiver in the activity that contains the view you want to render. Look at this answer:

Render your view in the onReceive() function of your BroadcastReceiver.

Answer 2

正如您将要使用AsyncTask ，您可以在onPostExecute()方法中呈现所需的任何视图，该方法在UIThread上运行。

Answer 3

在执行AsyncTask之前，我将显示一个进度条，然后在AsyncTask的onPostExecute（）方法中隐藏该进度条，并使用请求的数据更新视图。
