Solution

  • You can use TextWatcher to your EditText to do that in Android.

    Something like this

     EditText test = new EditText(this);
            test.addTextChangedListener(new TextWatcher() {
    
                public void beforeTextChanged(CharSequence s, int start, int count, int after) {
                }
                public void onTextChanged(CharSequence s, int start, int before, int count) {
                    try {
                       //write your code here
                    } catch (NumberFormatException e) {
                    }
                }
                @Override
                public void afterTextChanged(Editable s) {
                    // TODO Auto-generated method stub
    
                }
            });
