android listview, edittext same ID

Question

I got a listView in a fragment. This listView use an BaseExpandableListAdapter. I got a list of question and for each of them, I have a list of answer. I add a Edittext after each last answer == last child (to add a new answer).

My problem is that each edittext has the same ID, so when I have more than one question, I can't write inside the edittext because two edittext have the same Id. I don't know how to manage it :'(.

If you have any idea how to resolve it, it will help me a lot ! Thank you.

When I click on the edittext the keyboard open but instant lose the focus on the edittext and it's impossible to write inside

Answer 1

You can use setTag() method of view. So whenever your getChildView() executes just set editText.setTag(position). Once user submit the answer you just need to find the tag that in which edit test user has typed by edittext.getTag(). It will return you the position which you tagged at the time of getChildView() execution. By that way you can get to know different answers once you have more than 1 question.

getChildView() Code

@Override

public View getChildView(int groupPosition, final int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {

if (!isLastChild) {
    Answer answer = (Answer) getChild(groupPosition, childPosition);

    TextView text = null;

    convertView = inflater.inflate(R.layout.rowanswer_home, null);

    text = (TextView) convertView.findViewById(R.id.rowanswer_home_answer);
    text.setText(answer.getAnswer());

    text = (TextView) convertView.findViewById(R.id.rowanswer_home_author);
    text.setText("Anonymous"+answer.getUserId().toString());

    text = (TextView) convertView.findViewById(R.id.rowanswer_home_time);
    text.setText(answer.getDifferenceTime()+" ago");


}
else
{
    TextView text = null;

    convertView = inflater.inflate(R.layout.footer_answer, null);
    final Question question = groups.get(groupPosition);

    final EditText editText = (EditText)convertView.findViewById(R.id.footer_answer_edit_text);
editText.setTag(childPosition);
    final Button button = (Button) convertView.findViewById(R.id.footer_answer_button);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            String text_answer = editText.getText().toString();
            QuestionManager.getQuestionManager().addAnswer(text_answer, question.getId());
            groups = QuestionManager.getQuestionManager().getQuestionWithAnswerNotFromMe();
            notifyDataSetChanged();


        }
    });
    button.setEnabled(false);

    editText.addTextChangedListener(new TextWatcher() {

        public void afterTextChanged(Editable s) {

            // you can call or do what you want with your EditText here
            String text = editText.getText().toString();
int answeredPosition = (Integer)editText.getTag();
Log.d("Answered Position",""+answeredPosition);// This is the position of question in listview for which user has typed the answer.
            if (verifyFormatString(text)) {
                button.setEnabled(true);
            } else
                button.setEnabled(false);

        }

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

        public void onTextChanged(CharSequence s, int start, int before, int count) {
        }
    });

    InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);

    Log.d("test5780", String.valueOf(editText.getId()));


}

return convertView;

}

Let me know if it work or you need more descriptive answer.
