How To Stop The Items Duplication In RecyclerView Android

Actually my problem is when I click the item it go to a DetailsFragment. But when I return back to my ItemListFragment the items number is increased and duplication is occurred. Pl

Solution 1:

Do this

int i = 0;
    mArrayList.clear(); //Clear your array list before adding new data in it
    for (String name : mNames) {
        Data data = new Data(name, mPrices[i], mImages[i]);
        mArrayList.add(data);
        i++;
    }

By doing this your data won't duplicate anymore. Try it and let me know if it work for you.

Solution 2:

For one more help:

bundle.putInt("position", position);
bundle.putString("text", your_text_field);
...
fragment.setArguments(bundle);
