I am creating a android app in which i have a list of contacts. I am displaying the list of contacts in the list view using the following code :
setListAdapter(new ArrayAdapter(
getApplicationContext(),
android.R.layout.simple_list_item_1, ct_name));
where the variable ct_name is an array containing contact names. Now i want to add 2 images in front of each contact. The images are for calling and messaging option. The images will be same for all the contacts. Could anyone tell me how to display the 2 images in the list along with the contacts. As far as i have searched I guess i would have to make a custom adapter but i am not able to follow on how to do so. Could anyone help me with this?
You have to implement a custom ListAdapter.

I need to create a listview that looks like Stack of list items .
The list should be similar to the one that we see in the Notification Bar or else it should be like most recent Apps in Android L.
Can anyone help me with idea of how to implement such type of list or some sample code fragment.
Use Base Adapter . You can define the element of list anyway you want.
Try using ListView for the UI development and implement the suitable adapter for it.
You need to have three things:
Source of data which you want to display your list view.
Fragment/UI [List View] for displaying the data.
An adapter which binds data to list view.

I have made an application by usign Parse.com. I retrieve data to listview and spinner with Parse Query Adapter. Everything is cool till here. The problem occured when I try to use a custom layout for listview and spinner. I made the layouts but I couldnt find how to assign that layout to Parse Query Adapter. Another issue is I couldnt find a way to filter Parse Query Adapter for search feature. Is there any solution for these or any other ideas?
I also tried to retrieve all data with normal parse.com query to ArrayList and use regular ArrayAdapter but that also didnt work. I dont know why but I couldnt make spinner data select. It shows data as dropdown but none are selectable.
I have a question, if I want to load a ListView directly from a database, for example on the first screen I'll have a search button that will search the database and display the results in another screen in a ListView. How would I do that?
CursorAdapter or SimpleCursorAdapter will help you.
Your question has a few parts, if you don't already know how to start.
1) First you will need to learn how to set up a custom ListView and a generic adapter
http://www.vogella.com/articles/AndroidListView/article.html
2) Then you need to figure out how to source your adapter with data pulled from your database

I am new to android, can any one post the code for the below scenario.
I have set of data like first name, last name, date and id from arraylist to the listview to display, i need to filter it through id and when i click any item in the reduced listview, i need to pass the id so i can display that particular item details seperately in another activity and i have used Custom ArrayAdapter
I have created a demo project which is doing exactly what you need,but yes,you need to extend BaseAdapter for this rather than using ArrayAdapter.
here is the whole source code,

I am using this link to create custom listview in my app.
First I want to display listview with 5 items. As I scroll the list it should parse data and load listview for next 5 items.
Listview row contains 5 textviews.
How can I achieve this?
Please help me.
Thanks in advance
I want to display 5 items in single row
That has nothing to do with EndlessAdapter. That has everything to do with the ListAdapter you are putting into the EndlessAdapter. Start by not using EndlessAdapter and getting your list looking the way you want. Then, and only then, add in EndlessAdapter to add more data to the list as the user scrolls.
There are countless examples online of how to create rows in a custom ListAdapter that have more than one thing in them. Here is a free excerpt from my book on how to subclass ArrayAdapter, override getView(), and handle more than one widget in a row. You specifically will want to look at the "Customizing the Adapter" section.
