"Don't use edittext inside a listview" this is what most of the people say.. now I am thinking should have listened to them. I had a problem earlier when I added an EditText inside a ListView and encountered a problem related to click and I also posted a question regarding this(EditText and ListView are not working together) and also found a solution for that in(Focus on EditText in ListView when block descendants (Android)). After having so many obstacles I have been able to implement this,
But now I am having a recycle issue problem, I have an addTextChangedListener for the EditText in the ListView. Most of the people are suggesting to use setOnFocusChangeListener, but that is not an option for me as i have to change the EditText value of one row depending the value entered in the EditText of the other row. The problem currently I am facing is when I enter the value in the last row of the EditText, the same thing is reflecting in the first row. Can anybody help me to solve this issue. Here is the code snippet (Sorry for bad english)
public class MyBaseAdapter extends BaseAdapter {
ArrayList < ListData > myList = new ArrayList < > ();
LayoutInflater inflater;
Activity activity;
ListView lvDetail;

this.myList = myList;
this.activity = activity;
this.lvDetail = lvDetail;
