RecyclerView shows everything except first item

Question

I have a RecyclerView where each item is a LinearLayout containing two EditTexts and an ImageButton. The RecyclerView is showing every item except the first one of my data set.

Can anyone tell me what's going on?

public class EditListAdapter extends RecyclerView.Adapter<EditListAdapter.ListViewHolder> {

private ArrayList mListCardset;

public static class ListViewHolder extends RecyclerView.ViewHolder{
    public EditText frontEditText;
    public EditText backEditText;
    public ImageButton editActionButton;

    public ListViewHolder(View view) {
        super(view);
        frontEditText = (EditText)view.findViewById(R.id.front_edit_text);
        backEditText = (EditText)view.findViewById(R.id.back_edit_text);
        editActionButton = (ImageButton) view.findViewById(R.id.edit_action_button);
    }
}

// Provide a suitable constructor (depends on the kind of dataset)
public EditListAdapter(ArrayList aList) {
    mListCardset = aList;
}

// Create new views (invoked by the layout manager)
@Override
public EditListAdapter.ListViewHolder onCreateViewHolder(ViewGroup parent,
                                                 int viewType) {
    // create a new view
    View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.card_edit_item, parent, false);
    // set the view's size, margins, paddings and layout parameters

    ListViewHolder vh = new ListViewHolder((LinearLayout)v);
    return vh;
}

// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(ListViewHolder listHolder, int pos) {

    String[] eListItem = (String[]) mListCardset.get(pos); //get individual card @position
    listHolder.frontEditText.setText(eListItem[0]); 
    listHolder.backEditText.setText(eListItem[1]); 

}


private String[] strArrayListHelper(String frontString, String backString){
    String[] returnStrings = new String[2];
    returnStrings[0] = frontString;
    returnStrings[1] = backString;

    return returnStrings;
}

// Return the size of your dataset (invoked by the layout manager)
@Override
public int getItemCount() {
    return mListCardset.size();
}
}

This will only show items 2 through 5:

 mRecyclerView = (RecyclerView)findViewById(R.id.list_edit_recycler_view);

    ArrayList testListCards = new ArrayList<String[]>();
    testListCards.add(strArrayListHelper("Test 1","Test 1"));
    testListCards.add(strArrayListHelper("Test 2","Test 2"));
    testListCards.add(strArrayListHelper("Test 3","Test 3"));
    testListCards.add(strArrayListHelper("Test 4","Test 4"));
    testListCards.add(strArrayListHelper("Test 5","Test 5"));

    // use a linear layout manager
    mLayoutManager = new LinearLayoutManager(EditActivity.this);
    mRecyclerView.setLayoutManager(mLayoutManager);

    // specify an adapter
    mAdapter = new EditListAdapter(testListCards);
    mRecyclerView.setAdapter(mAdapter);

Answer 1

Maybe your Toolbar hides your first item of your RecyclerView.

Try to use this attribute

android:layout_marginTop="?attr/actionBarSize"

in your RecyclerView xml.

Hope that helps!
