I would like to get the link to any sample suggesting drag drop list item views, with multiple dynamic items/texts. I have googled a lot for it, but got samples with single textview using arrayAdapter.
I instead like to put drag drop on custom listview hence BaseAdapter instead of ArrayAdapter, and the textviews to be populated dynamically in the BaseAdapter's getView(), and drag drop accordingly.
Please guide, as I am facing a lot of trouble doing this.
In my code, I had a ViewPager which dynamically adds items as well. I think you may find this thread helpful. It helped me solve my problem, cheers. android drag and drop

I have a list of records in a listview that I want the user to be able to re-sort using a drag and drop method. I have seen this implemented in other apps, but I have not found a tutorial for it. It must be something that others need as well. Can anyone point me to some code for doing this?
provide me full example
Hi this is example of drag item in android list
https://github.com/woxblom/DragListView
In my android application, I've a ListView that is loaded with a lot of items. I would like that users could move very fast through the list. I've seen that in some applications, when a list is loaded, and the user starts scrolling, a icon appears on the right of the screen, and this icon can be used to move very fast through the list.
How can I do this?
Thank you very much!
You want android:fastScrollEnabled="true".
See Vardhan's implementation of Fast Scroll for android here.
If you want to be able to customize your Fast-scroller, like choosing
your own scroller image to appear, I recommend using this source:
https://github.com/nolanlawson/CustomFastScrollViewDemo/
Basically, your listview adapter will have to implement a
sectionindexer. This section indexer can be very stripped if you don't
want to complicate things and provide simple fastscrolling though the
entire length of the list.
The direct source for the fastscroller is here:
https://github.com/nolanlawson/CustomFastScrollViewDemo/blob/master/src/com/nolanlawson/customfastscrollviewdemo/CustomFastScrollView.java
Place this view around your listview (nest your listview inside this
view in your xml layout file) and set android:fastScrollEnabled="true"
on your listview.

I wonder if there is a tutorial or example code how the effect below achieved in Android, or if someone published an adapter already for this... Basically based on the number of results returned the screen is populated with boxes, and as the finger swipes down more boxes will load on demand until the results run out.
This is a GridView. And you can use your custom Load More GridView. This is a custom ListView example of the same. You can implement your own custom GridView similar to this.
What you are looking for is a Lazy List Adapter.
There is a great implementation for it. You can check it here. All what you need next is to create the layout of your list rows, i.e the boxes.
Does anyone have a good tutorial for implementing onItemClick() for a ListView populated by a custom ArrayAdapter?
I'm struggling with how Android is recycling views, and how to affect the layout of the selected view (which is a RelativeLayout). The way I've implemented it, I'm just doing a simple background colour change, but everytime I choose a row, when I scroll the ListView there are other off screen items selected too.
Any ideas?
Have a look to this answer. Custom code of ArrayAdapter.getView() (where view recycling is done) might be useful to you, I was trying to achieve something similar and it worked for me at last :)
You can find lots of good examples of the custom Listview with Adapters.Some of the Examples are listed below:
(1)custom-listview-android
(2)android-custom-listview-with-image-and-text
(3)Custom Array Adapter
I am trying to make a recipe ListView for food and I want to add imageViews next to items in my list. How can i do that? Thx.
A ListView item can have it's own custom layout.
You have to create your adapter for the ListView. When you create your adapter you can assign your custom layout.
Note: You will have to implement getView() to property set the image+text.
Here you have a sample: Lazy load of images in ListView
Following this tutorial could be a nice idea for you (mainly the second example).

But anyway, you should Google a little bit before asking such a basic question.
