How to add text watcher on inflated view

Question

I m using LayoutInflater to inflate same view multiple times. i want to set TextWatcher to watch text change of a perticular view. when i use my code then its not working. please help.

LayoutInflater inflater = LayoutInflater.from(UpdateUDISENext.this);
 View inflatedLayout = inflater.inflate(R.layout.udiseupdateview, null, false);
 headerLay.addView(inflatedLayout);
 ((TextView) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(0)).setText("class " + classvalue);
 totalmalestu = ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(0)).getChildAt(1));
 totalmalestu.setText(value);
 totalmalestu.setTextColor(Color.parseColor("#6bb40b"));

 totalfemalestu = ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(1)).getChildAt(1));
 totalfemalestu.setText(value2);
 totalfemalestu.setTextColor(Color.parseColor("#6bb40b"));
 totalstu = ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(2)).getChildAt(1));
 totalstu.setTextColor(Color.parseColor("#6bb40b"));

 ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(2)).getChildAt(1)).setText(String.valueOf(Integer.valueOf(value) + Integer.valueOf(value2)));

 totalmalestu.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

    }

    @Override
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

       if (totalmalestu.getText().toString().equals("")) {
                ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(2)).getChildAt(1)).setText(String.valueOf(0 + Integer.valueOf(totalfemalestu.getText().toString())));

       } else if (totalfemalestu.getText().toString().equals("")) {
               ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(2)).getChildAt(1)).setText(String.valueOf(Integer.valueOf(totalmalestu.getText().toString()) + 0));

       } else {
              String sum = String.valueOf(Integer.valueOf(totalmalestu.getText().toString()) + Integer.valueOf(totalfemalestu.getText().toString()));
              ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(2)).getChildAt(1)).setText(sum);
       }
    }

    @Override
    public void afterTextChanged(Editable editable) { }

   });

my layout have two edit text for male and female count. and one more is total. i want that if i change male or female edit text then it add and result sets on total. so i have used text watcher on male and female. but its not working because of more then one inflated layout of same type. — Karan, Sep 13 '17 at 07:55
its right but when i change male or female then its not changed in total. pic given is my inital state. before using text watcher. — Karan, Sep 13 '17 at 08:27
so you need to call `addTextChangedListener` twice: for male `EditText` and for female `EditText` — pskink, Sep 13 '17 at 08:31

You can get by with a single text watcher that is then registered with the two edit texts.

TextWatcher textWatcher = new TextWatcher() {
    ... as you had it ...
};

totalmalestu.addTextChangedListener(textWatcher);
totalfemalestu.addTextChangedListener(textWatcher);

You use same condition in 2 place

if (totalmalestu.getText().toString().equals("")) {
  ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(2)).getChildAt(1)).setText(String.valueOf(0 + Integer.valueOf(totalfemalestu.getText().toString())));

}else if (totalfemalestu.getText().toString().equals("")) {
   ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(2)).getChildAt(1)).setText(String.valueOf(Integer.valueOf(totalmalestu.getText().toString()) + 0));

}

First one will execute every time when totalmalestu.getText().toString().equals("")

So problem is your condition edit it it will work fine.

Suggestion

You can write code in afterTextChanged(Editable editable) rather then onTextChanged(CharSequence charSequence, int i, int i1, int i2)

@Override
public void afterTextChanged(Editable editable) {
    if (editable.toString().length()==0) {
       ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(2)).getChildAt(1)).setText(String.valueOf(0 + Integer.valueOf(totalfemalestu.getText().toString())));

    }else if (editable.toString().length()<2) {
         ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(2)).getChildAt(1)).setText(String.valueOf(Integer.valueOf(totalmalestu.getText().toString()) + 0));

    }else{
        String sum = String.valueOf(Integer.valueOf(totalmalestu.getText().toString()) + Integer.valueOf(totalfemalestu.getText().toString()));
        ((EditText) ((LinearLayout) ((LinearLayout) ((LinearLayout) headerLay.getChildAt(i)).getChildAt(1)).getChildAt(2)).getChildAt(1)).setText(sum);
     }
}

You can change your condition as you want... good luck ...
