How to add image on header in Navigation Drawer

How to add image on header in Navigation Drawer - android

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 !

1.Create a custom dialog and adjust to your needs, e. g. my_dialog.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/tv_dialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text"/>
<Button
android:id="#+id/btn_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_below="#+id/tv_dialog"
android:text="Button"/>
</RelativeLayout>
2.Declare and open dialog from activity:
my_dialog = new Dialog(context);
my_dialog .requestWindowFeature(Window.FEATURE_NO_TITLE);
my_dialog .setCancelable(true);
my_dialog .setContentView(R.layout.my_dialog);
my_dialog.show();

You can try this,
Change your code

searchAdapter.setData(results);
mListViewSearchUsers.setAdapter(searchAdapter);
textNotFound.setVisibility(View.GONE);
}else {

textNotFound.setText("No users found");
}
to
if(results.size() > 0){

if (searchAdapter== null) {
searchAdapter.setData(results);
mListViewSearchUsers.setAdapter(searchAdapter);
} else {
searchAdapter.setData(results);
mListViewSearchUsers.notifyDatasetChange();
}
textNotFound.setVisibility(View.GONE);
}else {
textNotFound.setVisibility(View.VISIBLE);
textNotFound.setText("No users found");
}
Change some code in adapter (comment some code)
public void setData(List<User> data) {
// clear();
if (data != null) {
addAll(data);
// notifyDataSetChanged();
}
}
Update:(problem resolved by comm‌ents this line)
mListViewTimeline.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
I hope this will help you.

How to implement endless scrolling listview

I am creating an application in which I am parsing data using Json parsing. I've implemented listview and in my response i have totalpage and current page objects,
A new user will get items from the first page. While the user is scrolling through the listview, the list expands with items from the next page (and the next and the next etc.)
this is my response
http://pastie.org/10259792
The following is code I've tried:
HomeFragment
public class HomeFragment extends Fragment {
// Listview Adapter
ListViewAdapter adapters;
// Connection detector
ConnectionDetector cd;
// Alert dialog manager
AlertDialogManager alert = new AlertDialogManager();
// Progress Dialog
private ProgressDialog pDialog;
// Creating JSON Parser object
JSONparserr jsonParser = new JSONparserr();
ArrayList<HashMap<String, String>> WebsiteList;
// albums JSONArray
JSONArray data = null;
String link_url;
ArrayList<HashMap<String, String>> arrayTemplist;
private AutoCompleteTextView inputSearch;
private ListView lv;
private static final String URL_ALBUMS = "";
private static final String WEBSITE_MENU_ID ="Brand_name";

You can achieve this by using the following library in Github
https://github.com/nicolasjafelle/PagingListView
Simple create your PagingAdapter and add it to com.paging.listview.PagingListView.
You have to implements the new Pagingable interface and its onLoadMoreItems() method. For example:
listView.setHasMoreItems(true);
listView.setPagingableListener(new PagingListView.Pagingable() {
#Override
public void onLoadMoreItems() {
if (pager < 3) {
new CountryAsyncTask(false).execute();
} else {
listView.onFinishLoading(false, null);
}
}
});
Finally you can use the onFinishLoading(boolean hasMoreItems, List newItems) method to update the list.
listView.onFinishLoading(true, newItems);
Also remember to use this package in your layout files:
<com.paging.listview.PagingListView
android:id="#+id/paging_list_view"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

Hello here you can find the nostra library for lazy loading and then you can

For the Example above you need to download the library universal image loader you can download the library ... happy coding :)

you didn't use EndlessListView in your Fragment. As I looked your response, it includes pagination. So, you need to request with page number to use endless scroll.
This is just flow for Endless Listview. If your code still doesn't work, I hope you can learn sample projects after read this messages. I added only parts you need. Thanks
Endless scroll only shows limited data on listview. When user scroll down to bottom, it will get next limited data from server. So you need to add current_page paramater in your request. I don't know exactly your api.
First, you need variable for current_page which initialize with 0
You have to know when to stop. You response has total_page field for that. Save and add validation
Then you need to know when to request next page. For that,you already have codes in onScroll within EndlessListView. That code calculate and tell when user scroll down to bottom and it called
listener.loadData();
to request new data. But you still need to add listener for that. You already have
public void setListener(EndLessListener listener) {
this.listener = listener;
}
You need to create Interface with the name EndlessListener and implements in your fragment. EndlessListener Interface will include loadData() function that request to server. After that you need to add listener for the listview.
endlessListView.setListener(this);

Try Loading data when listview reaches it's end. Implement OnScrollListener in your fragment. Refer this link Android - ListView to load more items when reached end

You MUST use Paging 3 library to resolve all problems in simplest way.

I want to add another block, or set, or whatever it is called, of items in my sliding menu but I can't figure out what to change to the code of the first... In my sliding menu I have 6 items, but I to have 4 items to the first title, and then, another title, and another 2 items.. but i can't figure out what do I have to change to my first block code..

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;
}
}
}
