Android set text values of xml layout from java

Question

I am trying to set the values of the android:text from the java code, while the program is running. It is intended to be a schedule program, and after the user logs in, I need to set the values of the text in the listview. The data is being read from a local JSON file, but from there, I am not sure what to do about setting the text values from the code.

Thanks, Androidonly42

Answer 1

You could use an Adapter , and once you have new data from your JSON file, update the model then call notifyDataSetChanged (on the UI thread), to refresh the content of your ListView . Also, have a look here .
