OnClickListener and changing TextView

Question

I have fragment with ListView. I set onClickListener on the button, and when the button is clicked, one text view in listview element change for example from "0" to "1". But nothing happens, have I refresh fragment or something else to see diference?

Answer 1

You need to call notifyDataSetChanged() from your adapter to reflect any changes in the listview adapter.

public void notifyDataSetChanged () Added in API level 1

Notifies the attached observers that the underlying data has been changed and any View reflecting the data set should refresh itself.
