To add a footer view in recyclerView you have to return the size of data, the recyclerView have to populate, + 1 from the getItemCount() method.
public int getItemCount() {
return listhistory.size() + 1;
}
Create a new viewHolder for the footer view and populate it with the appropriate footer layout that you have created.
Override the method getItemViewType(int position) to return an integer specific to each viewType
public int getItemViewType(int position) {
if (position == listhistory.size()) {
return 0;
} else {
return 1;
}
}
Change your onCreateViewHolder method to return appropriate viewHolder based on viewType;
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (viewType == 1) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.history_list_layout, parent, false);
return new HistoryViewHolder(view);
} else if (viewType == 0) {
View view = LayoutInflater.from(mContext)
.inflate(R.layout.footer_layout, parent, false);
return new FooterViewHolder(view);
}
return null;
}
Modify your onBindViewHolder() method so that it checks for the instance of the holder i.e., either HistoryViewHolder or FooterViewHolder and write the code accordingly.
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if (holder instanceof HistoryViewHolder) {
HistoyViewHolder historyHolder = (HistoryViewHolder) holder;
// All your existing code here and replace holder with history holder
} else {
// if you footer is static ignore this else part otherwise write the appropriate code
}
Hope this helps...✌

You could use an RecyclerView Decorator to achieve what you want, without touching your adapter.
Have a look at RecyclerView.ItemDecoration. Tell me if you want some more info about its usage.

try this ....
do(RST_CSTInfo.movetofirst()){

I guess that layout.activity_custom_spinner.xml is like this:
<Spinner id="#+id/spinnerTest" ...>
it should be like this:
<MySpinner id="#+id/spinnerTest" ...>
And MySpinner can be extends android.support.v7.widget.AppCompatSpinner.
https://developer.android.com/reference/android/support/v7/widget/AppCompatSpinner.html
This will automatically be used when you use Spinner in your layouts.
You should only need to manually use this class when writing custom
views.

How to add image on header in Navigation Drawer

I am using Gabriele Mariotti navigation drawer library to create the sliding menu. It works perfect, but I'm facing with adding an image, as header in it. It should look something like this:
I mean.. not exactly the same, but the idea of having the image as header. Thanks !

Thanks again !

I assume you want to achieve something similar to what is in the following picture:
You will have to modify your list adapter(NsMenuAdapter) to support two types of view - item and title where item is clickable and title is just kind of group header. Adapter should takes array/list of objects and every object should have type attribute. This will probably complicate a little OnItemClickListener.
I'm posting my example of that kind list adapter. In my case I created NavigationDrawerItem model to hold information about item type, item 'clickability' and what action should be triggered after item get clicked.
public class NavigationDrawerAdapter extends ArrayAdapter<NavigationDrawerItem> {
private static final String TAG = "NavigationDrawerAdapter";
public NavigationDrawerAdapter(Context context, int resource, NavigationDrawerItem[] objects) {
super(context, resource, objects);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (null == convertView) {
int itemType = getItemViewType(position);
if (NavigationDrawerItem.TYPE_TITLE == itemType) {
convertView = View.inflate(getContext(), R.layout.item_title_navigation_drawer, null);
} else if (NavigationDrawerItem.TYPE_ITEM_UNDER_TITLE == itemType) {
convertView = View.inflate(getContext(), R.layout.item_under_title_navigation_drawer, null);
} else {
Log.e(TAG, "Returning default title view - Invalid drawer item type" + itemType);
convertView = View.inflate(getContext(), R.layout.item_title_navigation_drawer, null);
}
}
TextView tv = (TextView) convertView.findViewById(R.id.text);
tv.setText(getContext().getString(getItem(position).stringRes));
return convertView;
}
#Override
public int getItemViewType(int position) {
return getItem(position).type;
}
#Override
public int getViewTypeCount() {
return NavigationDrawerItem.NUMBER_OF_ITEM_TYPES;
}
#Override
public boolean isEnabled(int position) {
return NavigationDrawerItem.isItemClickable(getItemViewType(position));
}
}
And the NavigationDrawerItem class:
public final class NavigationDrawerItem {
private static final String TAG = "NavigationDrawerItem";
// Types must have numbers from 0 to n without gaps.
public static final int TYPE_TITLE = 0;// nonclickable
public static final int TYPE_ITEM_UNDER_TITLE = 1;// clickabel
public static final int NUMBER_OF_ITEM_TYPES = 2;
public final int action;
public final String argument;
public final int type;
//Constructors etc.
public static final boolean isItemClickable(int itemType) {
if (TYPE_TITLE == itemType) {
return false;
} else if (TYPE_ITEM_UNDER_TITLE == itemType) {
return true;
} else {
Log.e(TAG, "Invalid item type " + itemType);
return false;
}
}
}
