I suggest you to rewrite your getView() method, because I think that you are wrongly using ViewHolder pattern. Read this: http://www.jmanzano.es/blog/?p=166
Or just get rid of ViewHolder and code getView() without it.

RecyclerView Adapter not returning correct cursor position

I have been trying to figure out how to make RecyclerView Adapter work with clickable images from a db. My app always crashes with the error "android.database.CursorIndexOutOfBoundsException: Index 4 requested, with a size of 4" when an image is clicked. When I add more items to the db, the index in the error increments as well. Please any help will be appreciated. See code snippets below.

Error is in below code, it always return plus 1 index, because you write cursor.getCount()+1:
#Override
public int getItemCount() {
return (cursor == null) ? 0 : cursor.getCount() + 1;
}
Replace code with:
#Override
public int getItemCount() {
return (cursor == null) ? 0 : cursor.getCount();
}

#Override
public int getItemCount() {
return (cursor.getCount());
}

After many days of struggle, I finally found a solution to my problem. See code below. Many thanks to #Caspain and #Asif.

}
}
}
});
holder.tv.setText(listData.get(position).getPOOJA_LISTING_NAME());
return convertView;
}

int countermax = 0;

For Recyclerview try this way
http://android-pratap.blogspot.in/2015/01/recyclerview-with-checkbox-example.html

#Override
public int getViewTypeCount() {
return getCount();
}
#Override
public int getItemViewType(int position) {
return position;
}
Add two functions into your "Adapter" class
Note: If you use RecycleView, just add getItemViewType(int position).

android ListView adapter with three different xml items

I am trying to create a listview with three different item types I have a code that works with two XML files
Here is the adapter code:
private class MyCustomAdapter extends ArrayAdapter<String> {

private String humidity;

private static final int TYPE_TOP = 2;
private static final int TYPE_MAX_COUNT = 3 + 1;
private ArrayList<String> mData = new ArrayList<String>();
private LayoutInflater mInflater;
private TreeSet<Integer> mSeparatorsSet = new TreeSet<Integer>();
public MyCustomAdapter(Context context, int resource) {
super(context, resource);
mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void addWeather(final String place,final int image , final String temp,final String humidity,final String windspeed,final String condition) {
mData.add(place);
this.place = place;
this.image = image;
this.temp = temp;

I tried creating a method called "addFavapp" to add my third XML file but I couldn't get it to work.
Help please.

Got it fixed by replacing
return mSeparatorsSet.contains(position) ? TYPE_WEATHER : TYPE_TIME;
Inside the getItemViewType
To
return position;

Android ListView lags with ImageLoader

I am using androidimageloader.com and get a good bit of flicker as images load into the list, much unlike the demo and apps that use it. I have the imageLoader in the application class, and don't get why it flickers. The images are Facebook profile pictures for users. What would be causing this? Here is my adapter:
public class FriendAdapter extends BaseAdapter {
private Typeface tf;
LayoutInflater inflater;
private String[] nameEvents;
private String[] urls;
private ArrayList<Friend> friends;
ImageManager imageManager;
ImageTagFactory imageTagFactory;
public FriendAdapter(Activity activity, ArrayList<Friend> friends) {
this.friends = friends;
setData(this.friends);
tf = Typeface.createFromAsset(activity.getAssets(),
"fonts/Roboto-Condensed.ttf");
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
imageManager = BuzzbabaApplication.getImageLoader();
imageTagFactory = new ImageTagFactory(activity, R.drawable.no_pic_icon);
}
public View getView(int position, View convertView, ViewGroup parent) {
FriendView fView;
if (convertView == null) {
convertView = inflater.inflate(R.layout.friend_layout, null);
fView = new FriendView();
fView.name = (TextView) convertView.findViewById(R.id.friendName);
fView.name.setTypeface(tf);
fView.pic = (ImageView) convertView.findViewById(R.id.profilePic);
convertView.setTag(fView);
} else {
fView = (FriendView) convertView.getTag();
}
fView.name.setText(nameEvents[position]);
// HomeScreen.imageLoader.DisplayImage(urls[position], fView.pic);
((ImageView) fView.pic).setTag(imageTagFactory.build(urls[position]));
imageManager.getLoader().load(fView.pic);
return convertView;
}
public void setData(ArrayList<Friend> friends) {
nameEvents = new String[friends.size()];
urls = new String[friends.size()];
int index = 0;
for (Friend f : friends) {
String pos = f.getName();
int num = f.getNumEvents();
if (num == 1) {
pos = pos + "\n" + num + " event";
} else {
pos = pos + "\n" + num + " events";
}
nameEvents[index] = pos;
urls[index] = f.getPictureURL();
index++;
}
}
static class FriendView {
TextView name;
ImageView pic;
}
public int getCount() {
return friends.size();
}
public Object getItem(int position) {
return position;
}

How to create listview for displaying sender receiver messages using baseadapter?

when we scroll down or up getview problem?
getview not called properly?
at background images are loading from respective url?
layout is different for sender and receiver..

It is better to reuse convertView only when both the layouts are the same. As the layouts are different here, when you reuse a convertView used by sender for receiver, then the view may not be as expected.
