I have searched as much as I could on google, I have search as much as I can find on here, I am seriously at a loss, my co-workers are unhelpful, i just want someone to look at this and tell me what it is I am missing that is causing the listview not to refresh the data. The Logs are showing that is is containing the correct number of elements but its not showing in the list.
public class ShiftListViewFragment extends Fragment {
private static int TOTAL_ITEMS = 11;
private static String TAG = "ShiftListViewFragment";
private ListView mListView;
private ShiftItemArrayAdapter mAdapter;
private ArrayList<ShiftItem> mShiftItems = new ArrayList<ShiftItem>();
;
private ArrayList<ShiftItem> displayShiftItems = new ArrayList<ShiftItem>();
private Button mPageLeftButton;
private Button mPageRightButton;
private int mPageNumber = 0;
private int mPageIndex = 0;
public static ShiftListViewFragment newInstance() {

return shiftListViewFragment;
}
public ShiftListViewFragment() {
}
public void populateShiftItems() {

new ShiftItem(new ShiftDto(clockIn, clockOut, breakTimeIn, breakTimeOut));
mShiftItems.add(shiftItem);
}
}
public void populateDisplayShifts() {
int lowerBound = mPageIndex * 11;
int uppBound = lowerBound + 11;
if (uppBound > mShiftItems.size()) {
uppBound = mShiftItems.size();
}

}

}
public int getPageNumber() {

if (pages % 11 != 0) {
pages++;
}
Log.d("TAG", "TotalPages " + pages);

return pages;
}
private void initViews(View view) {
mListView = (ListView)view.findViewById(R.id.shift_report_list);
mPageLeftButton = (Button)view.findViewById(R.id.btn_page_left);

}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.shift_list_report_fragment, null);
initViews(view);
populateShiftItems();
mPageNumber = getPageNumber();
mAdapter = new ShiftItemArrayAdapter(getActivity(), R.layout.shift_list_item,
displayShiftItems,
R.color.shift_list_item_bg);
mListView.setAdapter(mAdapter);
populateDisplayShifts();
mPageRightButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mPageIndex++;
if (mPageIndex > mPageNumber - 1) {
mPageIndex = 0;
}
populateDisplayShifts();
Log.d(TAG, "Page:" + mPageIndex + " Actual items in list:" + mAdapter.getCount());
}
});
mPageLeftButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mPageIndex--;
if (mPageIndex < 0) {
mPageIndex = mPageNumber - 1;
}
populateDisplayShifts();
Log.d(TAG, "Page:" + mPageIndex + " Actual items in list:" + mAdapter.getCount());
}
});
return view;
}
}
And my adapter
public class ShiftItemArrayAdapter extends ArrayAdapter<ShiftItem> {
private LayoutInflater mLayoutInflater;
private int mAlternateColorResource;
public ShiftItemArrayAdapter(Context context, int resource,
ArrayList<ShiftItem> shiftItems,
@ColorRes int colorResID) {
super(context, resource, shiftItems);
this.mAlternateColorResource = colorResID;
this.mLayoutInflater = LayoutInflater.from(context);
}
/**
* Applies background resources in an alternating fashion, based on the view's position.
*/
protected void applyBackground(int position, @NonNull View convertView) {
if (position % 2 == 0) {
convertView.setBackgroundResource(mAlternateColorResource);
} else {
convertView.setBackgroundResource(android.R.color.white);
}
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
String clockedIn = getItem(position).getInTime();
String clockedOut =
getItem(position).getOutTime();
if (convertView == null) {
viewHolder = new ViewHolder();
convertView = mLayoutInflater.inflate(R.layout.shift_list_item, null);
viewHolder.clockedInTextView = (TextView)convertView.findViewById(R.id.time_in);
viewHolder.clockedOutTextView = (TextView)convertView.findViewById(R.id.time_out);
viewHolder.dashedTextView = (TextView)convertView.findViewById(R.id.dash);
viewHolder.breakTotalTextView = (TextView)convertView.findViewById(R.id.break_total);
viewHolder.totalTimeTextView = (TextView)convertView.findViewById(R.id.total_time);
viewHolder.clockedInTextView.setText(clockedIn);
viewHolder.clockedOutTextView.setText(clockedOut);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder)convertView.getTag();
}
Date breaksIn = new Date("11/11/2015 11:20 AM");
Date breaksOut = new Date("11/11/2015 12:20 PM");
String breakHours = String.valueOf(
DateHelper.getTimeDuration(breaksIn, breaksOut, false).getStandardHours());
String breakMin = String.valueOf(
DateHelper.getTimeDuration(breaksIn, breaksOut, false).getStandardMinutes());
viewHolder.breakTotalTextView.setText(breakHours + " HR " + breakMin + " MIN ");
applyBackground(position, convertView);
return convertView;
}
private class ViewHolder {
public TextView clockedInTextView;
public TextView dashedTextView;
public TextView clockedOutTextView;
public TextView breakTotalTextView;
public TextView totalTimeTextView;
}
}
Any and all help would be appreciated.
Apparently there is a bug in Android where the list items in a listview have trouble defining their actual size, so the solution was to set the list_item.xml to a specific height instead of wrap_content.
