Android ListView行文本动态更改

Question

I have a ListView with BaseAdapter and I create this adapter in my main Activity. In my adapter constructor, I also have an String list that fills the TextViews in ListView rows in "getView" method. After that, according to user interaction, I want to change text of TextViews in ListView rows, but how could I manage?

Answer 1

Update string or stirngs in your Adapter's "String list" and than call BaseAdapter's notifyDataSetChanged() method.

This will notify all listeners that data is changed and in your particular case will result in ListView re-fetching visible views from your Adapter. And your Adapter will return views with new updated strings.
