You need to add a `TextWatcher` for each view where you want to do something as soon as the text changes. Then if it is editview 1, add text to tv1 etc if it is editview 2 add text to tv2... — nem035, Sep 23 '14 at 12:39
Please remove all unrelated code - and only leave in the parts of the code the are relevant. — Aleks G, Sep 23 '14 at 12:42
@Ravi I read your question and re-read it again and, frankly, I don't quite understand what you're after. What I do see is that you dumped your entire activity code in the question whereas there's probably about 10 lines that are relevant to your question. — Aleks G, Sep 23 '14 at 12:44
ok what is want to do is that i want to show first custom list view record to second list view how to do this.. — Ravi, Sep 23 '14 at 12:51

It's hard to understand what you're trying to do, but one thing is clear: you don't seem to understand how listviews work. You cannot change display elements of the list view directly - you have to change the data behind the adapter and then call notifyDataSetChanged.

You need to have some data structure to keep the data for each of the list views. Inside the adapter for your first ListView you need to have a reference to the data structure for the adapter of the second ListView. Then, inside your text watcher, when you need to update something in the second list view, you need to modify the data inside that data structure for the second list view and call notifyDataSetChanged on it for the changes to be reflected on screen.

Obviously, you'll need to modify your second adapter (and specifically the getView method) to create a view based on the content of the data structure and the index of the row.
