Android: Draw custom border around listview? - android

I've got a ListActivity with a ListView in it. I need to draw a repeating image around the border ("on top of it (I guess after the listview is renderered))
How can I hook in my own drawing code for this?

You can use a FrameLayout to cause the ListView to overlap with a view that fills the entire screen. In this background view you could tile an image, or write your own custom View with your own drawing method.

There is no border property in ListView, as far as I know.
Instead you can put ListView into a FrameLayout and set the Background color of the FrameLayout.
Finally, set some padding to FrameLayout in order to create a border effect.

Hi
There is one way I have used, but that can be done in XML only.
android:background="#ffffff"
android:divider="#ffcccccc"
android:dividerHeight="1dip"/>
What I am doing is, putting listview in a LinearLayout. Background color of the list is different than that of layout. There is a margin set for layout. Hence the distance between list and layout will appear like a border for the listview.
Hope this helps.

How to draw overlapping views?
I would try setting negative values for vertical paddings, but it's a wild guess. Also, you can just divide the graphics and draw views as rectangles containing view N and some parts of the N+1th view.
What about non-rectangular hit area?
You can manually detect clicks using color picking, shapes, or just simplify the view's clickable area to a rectangle.
What about visibility detection?
ListView shows only views, which are visible. I'm not sure, but most likely it won't work with negative paddings or similar hacks.
Personally I would write a custom view with ListView-like adapter and dynamic row loading.
I have try a many ways, and the best and fastest is simple set negative divider to listview like so:
android:dividerHeight="-100dp"

"Glooming" effect layer on the bottom of ListView

Currently, I have an Activity, with a ListView on the top, and LinearLayout on the bottom.
When a row in my ListView is scrolled and the row is partially shown, it looks like this. (LinearLayout is the one with Value wording)
However, I wish to have the following effect.
It seems that LinearLayout adds a "glooming layer" at the bottom of the ListView. - I am sure this is not optical illusion. :)
How I can achieve such an effect?
Add
android:requiresFadingEdge="vertical"
on ListView will solve the problem
One of the ideas that comes in my mind right now is to create a shape with a transparent gradient color. Then create a View above the LinearLayout and put the Shape as the background.
Another idea is to put a transparent image, instead of shape, above LinearLayout.

Customized ListView with scolling background

EDIT: Solved this by from Java-code adding headers and footers with transparent background to the ListView.
Hi, I'm trying to make a ListView that has a gradient as a background and the content inside a frame. I have some screenshots of what I'm trying to acheive.
The first screenshots shows how I want it too look from start. The list is shown in a box with rounded corners and a green background. This is acheived by adding padding to the LinearLayout surronding the ListView. However, when I add padding on top, the scrolling looks like in the third picture, which is not what I want. The first field with name and phonenumber is a header for the listview.
Any suggestions on how to make the listview behave like this?
You should use Relative layout for solving this problem.

How to create an UI similar to the attached image?

I am trying to create an UI just like the attached image!
How do we create these types of UI? Is it a ListView? And how do we get the arrow button on the right hand side? How should I start with such kind of layouts?
You can achieve that with a LinearLayout too.
Have that LinearLayouts orientation be vertical. Create such list items (it isn't related to ListView) using RelativeLayout.
Have the icon be an ImageView aligned to its parent left and vertically centered, the text would be a normal TextView which is to the right of that icon and vertically centered as well and finally another ImageView but this time aligned to its parents right and vertically centered.
These is the receipt.
It's a ListView, you should learn how to write your own ArrayAdapter and returns in the getView method the View you want to be each row of the ListView.
AnDroidDraw lets you create the layout online and then later download it on your device. http://www.droiddraw.org/
Create appropriate custom ArrayAdapter for this layout.

Android Listview ArrayAdapter example

I am using custom row view in ListView widget.
I am having getView method in my implementation.
What I want is that I want to hide divider image of 2nd row how can I do it?
If you're talking about the image that displays when you call setDivider, or android:divider in XML, I don't think you can hide it on some rows and show it on other rows.
Instead, you can create a PNG (probably with draw9patch) with a border on the top or the bottom, and in your ListAdapter.getView() set it as the background on whatever rows you want. On the other rows, you can set a background that has no border. This will give the appearance that some rows have a divider, and others don't.
