java.lang.IndexOutOfBoundsException: setSpan (2 ... 2) ends beyond length 1

Question

I got this exception, i am new for android so please help me.

E/UncaughtException: java.lang.IndexOutOfBoundsException: setSpan (2 ... 2) ends beyond length 1

    holder.oldLaundriesQuantityEditText.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) {

            if(s.toString().length()>0){
                int editedQuantity = Integer.parseInt(s.toString());

                if(editedQuantity==0){

                    finalHolder.oldLaundriesQuantityEditText.setText("1");

                }
                if(editedQuantity>oldLaundriesModelArrayList.get(position).getRemain_quantity()){

                    finalHolder.oldLaundriesQuantityEditText.setText(String.valueOf(
                            oldLaundriesModelArrayList.get(position).getRemain_quantity()
                    ));

                }

                finalHolder.oldLaundriesQuantityEditText.setSelection(count);
            }

        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });

Is the exception occuring on this line? `finalHolder.oldLaundriesQuantityEditText.setSelection(count);` — Dinash, Jul 18 '17 at 08:05

This issue happens when you have already entered the text of length 2 say "10" but the remaining quantity returns a single digit one say "9", in that case the count value will be 2. And on setting selection you are using count value and there is a string of length 1 only but setting to 2.

Instead of

finalHolder.oldLaundriesQuantityEditText.setSelection(count);

use

finalHolder.oldLaundriesQuantityEditText.setSelection(finalHolder.oldLaundriesQuantityEditText.getText().toString().trim().length());

For a better and cleaner one, store the value of

String.valueOf(oldLaundriesModelArrayList.get(position).getRemain_quantity());

to a string before setting to the edittext and then use the same string object to get the length of the string.

code is working but on this screen the app not responding when i debug this than inside on "onTextChanged" debugging continue for infinite ...plz tell how to solve this ? – Hafijur Rahman Jul 18 '17 at 09:21
So, when we change text inside a text change listener, I runs into infinite loop as discussed on this link. https://stackoverflow.com/questions/9385081/how-can-i-change-the-edittext-text-without-triggering-the-text-watcher So simply use a boolean flag to avoid the infinite loop – Dinash Jul 18 '17 at 09:38
I have solved this kind of issue by this https://github.com/RedMadRobot/input-mask-android/issues/27 answer. – Ninja Jun 04 '18 at 09:40

check size this oldLaundriesModelArrayList

if(oldLaundriesModelArrayList.size() > 0 && position <= oldLaundriesModelArrayList.size() ){
    finalHolder.oldLaundriesQuantityEditText.setText(String.valueOf(oldLaundriesModelArrayList.get(position).getRemain_quantity())); 
}
