i also want to group them in that when a section automatically fills itself the user is immediately brought to the next section. e.g When he/she fill in "how many people tested" female 0 and male 0 the next segment up to how many contacts automatically fills to 0. `

You can use interface. if so, you should first set addTextChangedListener() in your desired edittext, then set interface in one of the addTextChangedListener() method.

example:

first define interface

public interface mInterface {
    void onEditTextAction(String key);
}

then

mEditText.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

            }

            @Override
            public void afterTextChanged(Editable s) {
                  mInterface.onEditTextAction(s.toString());
            }
        });

you can use mInterface.onEditTextAction(s.toString()); in each text change listener methode you like. it passes the text entered in edittext to interface for further use. then in your activity

mInterface myInterface = (mInterface) mContext;

and at last use

new  mInterface() {
    @Override
    public void onEditTextAction(String key) {
        // use edittext string here
    }
};

and change whatever you want.
