Question

I need to update my ListView according to the userinput in SearchDialog. For this I need to set a TextWatcher for SearchDialog. How to do this?

Answer 1

you can do it as below:

yourEditText.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        // process new items for list view

    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,
            int after) {
        // TODO Auto-generated method stub

    }

    @Override
    public void afterTextChanged(Editable s) {
        // push new items into adapter and call notifyDataSetChanged() on it

    }
});
