Edittext in listview | Focusable EditText inside ListView in android

There is a common issue which we are facing in EditText in side listview.

-Issue with focus of edit text within listview row.
-Reset editText value while scrolling listview.

I have found some solutions to overcome this kind of issue in listview.

Note : we can solved any of issue which is related with listview using this sample.
