how to change the background color of TextView if EditText is empty in android?

Question

I am using Fragment class in which I want to change the color of TextView When EditText is empty after text is changed. I am able to change the color of TextView on text change but when the text is clear the TextView background color doesnot change to previous one. What are the possible ways to change the background color of TextView When EditText is empty after text is changed . My code looks like this :

public class Fragment_AboutUs extends android.app.Fragment {
TextView about_btn_call_customer;
TextView about_btn_Submit;
EditText about_feedback;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.layout_fragment_about_us, container, false);
    //reference section
    about_btn_call_customer= (TextView) rootView.findViewById(R.id.about_btn_call_customer);
    about_btn_Submit=(TextView)rootView.findViewById(R.id.about_btn_Submit);
    about_feedback=(EditText)rootView.findViewById(R.id.about_feedback);


        TextWatcher textWatcher = new TextWatcher() {
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {




            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {


            }

            @Override
            public void afterTextChanged(Editable s) {

                String textinEdit=  about_feedback.getText().toString().trim();
                if (textinEdit != null) {
                    about_btn_Submit.setBackgroundColor(getResources().getColor(R.color.light_green));

                }else if (textinEdit ==""){
                    about_feedback.setBackgroundColor(getResources().getColor(R.color.grayColor));
                }

            }
        };

    about_feedback.addTextChangedListener(textWatcher);






    return rootView;
}

}

Thank you in advance ...any kind of help would be appreciated...

Answer 1

check count onTextChanged and choose the color:

@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
   int color = count == 0 ? R.color.light_green : R.color.grayColor;
   about_btn_Submit.setBackgroundColor(getResources().getColor(color));
 }

and you could do the same thing for the other TextView
