Trying to get ids of child views under a table row

I am developing an app which has long forms so its kind of difficult to manually do findViewById for each screen. I have following structure in the screen where I am stuck.

Relative layout
->TableLayout
-->TableRow
--->And then each table row has 3 edittext in its own columns.

I am doing this 

           TableLayout table = (TableLayout)findViewById(R.id.screen8_table1);
           int rowCount = table.getChildCount();

           TableRow rows = (TableRow)table.getChildAt(0);
           int viewCount = rows.getChildCount();
           EditText thisView = new EditText(getApplicationContext());
           View theView = rows.getChildAt(1);
           int Id = theView.getId();
           thisView.findViewById(Id);
           text = thisView.getText().toString();
           Log.i("View value",text);

When I try to get the ID is shows -1. Please help.

After the answer from Pavneet Singh I made this one change in the code

        FloatLabeledEditText et_one = (FloatLabeledEditText)rows.getChildAt(1);
        text = et_one.getEditText().getText().toString();

and now its working properly. Save me a tons of lines of code here!

You are creating a new EditText which is not a child of TableRow.

EditText thisView = new EditText(getApplicationContext());
View theView = rows.getChildAt(1);
int Id = theView.getId();

You can directly fetch it as

EditText eText_one = (EditText)rows.getChildAt(1);
// no need to use any id to fetch edittext reference
text = eText_one.getText().toString();

Update : you are using customize editext so use

 com.wrapp.floatlabelededittext.FloatLabeledEditText et_one =
                  (com.wrapp.floatlabelededittext.FloatLabeledEditText)rows.ge‌​tChildAt(1);

Although this can be achieved with TextInputLayout provided by design library
