ListView中的EditText？

Question

I am using this code for getting the value of edittext in a list view.

     View view = listview.getChildAt(position);
     EditText text = (EditText)view.findViewById(R.id.myEditBox);
     String contents = text.getText().toString();

But the problem is that when i scroll the list view ,position changes and i am getting a different result.ie if i scroll,the element at fifth position gets at the top and its position becomes 0.Is there any remedy for that?

You will have to create an Adapter for your listview if you haven't already done that, and on your adapter when you set your views add a textwatcher and report when the text is changed to your activity or fragment.

On your adapter:

edittext.addTextChangedListener(new TextWatcher() {

                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void beforeTextChanged(CharSequence s, int start, int count,
                        int after) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void afterTextChanged(Editable s) {
                    ((MyActivity) getContext()).textChanged(s.toString());

                }
            });

On your activity

public void textChanged(String s){

       //do somthing with the string
}

That way you don't have to guess the position fo your edit text
