I would like to have in my activity the widget like this in the top of that screen. I do not think about clock, but about that 5 balls, and I want to use it the same way - when I change screen then white ball is changing too. I was looking for information about it on Android Developer but I can't found any tips. What type of widget I have to use or do I have to write all code for this from zero?
It calls ViewPagerIndicator
here is https://github.com/bigsolom/AndroidViewPagerIndicator
custom ViewPager indicator the mimics nexus-5 launcher style (small circles and the selected page is a bigger circle)
hope that will be helpful

I have an activity that must be used horizontally.
this activity shows a map and when i click on it a toolbar supposed to pop from the right side of the screen (which is actually the bottom if we are looking vertically).
(Sorry for posting link instead of image, reputation doesn't allow me images)
http://i60.tinypic.com/xlb12g.jpg
i thought of implementing this toolbar as a container of fragments because each button triggers different stuff to appear on the toolbar.
First of all, is it the best way to implement such a toolbar? or are there more android oriented ways?
Second, i would like that when i touch the "transparent" space under the X button it would send this signal to the map but when i touch the "black transparent" it will not.
From what I've read the only way is when clicking check coordinates and see of they fall inside my area but it sounds too hardcoded and ugly solution.
Is there a better one? maybe there is a way to make the holding layout fit the image and not be rectangular?
For a more android oriented way you can use the Navigation drawer.
I don't know if it fit exactly with what you want but Navigation drawers are a good way to create right or left menu/toolbar.
You can find the documentation here:
https://developer.android.com/design/patterns/navigation-drawer.html
http://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html
Android provides the SlidingDrawer by default looks like below image -

Can we customize this SlidingDrawer looks like semi-circle type with buttons included. For, example take a look at below image -
Anyone done the SlidingDrawer like above one. I've googled it. Didn't get any nice solution for this. Anyone has idea/example blog for this?
So make sure you have Gimp and 9-Patch at the ready for a lot of trial and error...
Then what you wanna do is...
Add suitable layout to hold buttons where the current ImageView Handle is, like Horizontal LinearLayout or RelativeLayout
Cut the id of the current ImageView Handle and add it to this new Layout you just added
add your buttons to the LinearLayout/RelativeLayout (you can test it now, the buttons and the handle should all slide open at the same time)
Now add Button listeners for each of the buttons
Set the SlidingDrawer to android:allowSingleTap = "false" (tit for tat, you cant have the single tap option anymore, just the slide)
Use a ButtonSelector.xml to have different layouts for buttons be pressed or not pressed.
This is the hard part. Edit the drawables for the buttons, and handle so that they will fit together nicely if the screen is huge, small, landscape, portrait. I recommend using 9-Patch in conjunction with Gimp.
Pat yourself on the back because you now have a totally sweet custom sliding drawer.
Make sure you post pictures and state any problems or issues you ran into as I have never fully implemented this, but I did get to step 6 to make sure it was possible.
Last but not least, Good Luck...
Thanks for RelativeLayout and FrameLayout These layouts makes my requirement comportable with what i need. I've done like below steps -
First, i've splitted the full image into three pieces. And, merge these images with FrameLayout And, gave onclickListner to my center of image(Because, it was contain that arrow marks up/down)
And, i've used the Animation for just to open that View as SlidingDrawer
These steps helps me lot.
I'm working on implementing a UI for an Android application, and I wanted to ask if there is already something in the native widgets to accomplish most of what I'm trying to do.
The application that I'm working on performs 15 different tasks that can be divided into 3 different groups. (5 tasks per group) I have 18 icon images (3 for the groups and 15 for the individual tasks) and I want to be able to panel these icons (starting with the groups) like this:
I want the next icon visible below and above (if further down than the first icon) and swipe to go to the next icon
Once an icon is clicked, the panels slide to the side, exposing the next layer (the specific 5 tasks for the selected group) with the selected group still visible on the side:
From there, the user can tell at a glance what group they are in, what the current, next and previous selectable tasks are, and that by swiping right, they can get back to the group selection.
What types of widgets would I need to look into in order to accomplish something like this? Are there already pre-built lists to do these activities?
Thanks for any guidance!
You can get close with a LinearLayout of ImageView widgets and a ScrollView (vertical) or HorizontalScrollView. However, it will not give you the desired "centered image with bits of the previous/next images" effect -- it will be wherever the user positions it.
You can get close with a Gallery. However, it will not give you the vertical orientation, and it will always give you a fixed set of full options to the sides, not the partial images that you seek.
If it's gotta be the way you describe it, you'll have to roll it yourself. Gestures and animations should give you the desired effect.
Have you taken a look at ViewFlipper? http://developer.android.com/reference/android/widget/ViewFlipper.html This will give the side by side effect but you will have to make custom views for each group to populate it with the proper icons.
I'd use a ListActivity for the first 3 top level items. This won't give you the auto centering effect that you'll probably want, but you should be able to look at the Gallery source code, which can be found here, and make some modifications to the ListActivity so that it autocenters.
For the next items, I'd add an onClick and a GestureListener so you can navigate to another activity with another list view. Since you know where you came from (add some data to your Intent) you can set the color rectangle on the left so that it appears that you have just swiped the whole view left.
If you need to customize the animation, you can call this:
overridePendingTransition(R.anim.slide_left_entry, R.anim.slide_left_exit);
To make the yellow icon look good as it animates to the left, I'd change the list bounds (on the first activity) to have no margins, and change the yellow icon to have square right edges - This will make the small yellow rectangle on the next activity appear to be part of the first activity.
It should be relatively easy to mock this up to see if it's going to work properly for you.
Good luck!
EDIT: Ok, so I've made a basic project that does most of what you want.
here is the link to the eclipse project file. I was going to put the source up here, but there's a bit much to display.
What you still have to do:
Tweak animation
Configure the layer lists to display the correct colors
Add information to the top level intent for the sub-activity to be able to configure itself.
Quite a few other small things.
I think I've got the main stuff done. I've also added the gesture listener I talked about, although re-reading your question, you actually didn't ask for that. Since it's cool, I left it in.
Good Luck once again!!
Have you thought of launching Activities with different view configurations? You can switch from one activity to another with a gesture and you can Animate the views. What your UI looks like to me is a bunch of screens with affordances that show the other screens. So one Activity per screen maybe the same in different configurations or something like that.
Is it possible to change the size of the tabs displayed in a TabActivity? I'm currently only putting text in my tabs and I'd really like to minimize the size as much as possible.
Also, is there a way to use icons for my activity that aren't 48x48? I'd like to do something more rectangular as opposed to square. I just want to use my screen real-estate the best I can :)
How is the YouTube app doing this? (See screenshot, and yes I know that the YouTube app isn't open source)
It seems that they're also making it possible to scroll left and right for more tabs. Any ideas on how they're doing this?
Yest you can do all that by creating your own custom view for tab widget, it is quite simple to do. this tutorial will do the trick

I am looking for a UI view that imitates the functionality of the
Google Maps directions screen UI control where it allows the user to
pick the type of directions allowed, either Car, Transit or Walking.
Like this --> http://snapplr.com/50rh
The widget is essentially three buttons laid out horizontally with
rounded corners only on the left of the first and right of the thirdbutton.
I can't see a standard way to do this, although it seems like it would
be a common widget. Is there some other standard way of presenting a
multi-choice grouping in a horizontal layout as a "single" layout
object.
I am not aware of a button bar widget in the Android SDK. You would create one with ImageButtons in a LinearLayout, with custom backgrounds for all (to give the gloss-black look, to handle the varied sets of corners, and to handle the selected vs. not imagery). You would then need to add the toggling smarts, such that pushing one makes it selected and makes the others in the layout not selected.
If you wish to stick to simpler existing widgets, Spinner, RadioButton, or ToggleButton would be the most likely candidates.
I don't think there is a built-in way to do it. I can think of two ways to accomplish it. The first would be to create a custom style for the TabWidget. The second would be to create your own custom widget. Making a TabWidget style might be more flexible because you could easily come back and add or remove tabs and it would update accordingly. Making your own custom widget would give you much more control over how the widget looks and acts. So really you need to see what would be the best fit for what you're trying to do.
Best button bar I've found: http://androidworkz.com/2011/02/04/custom-menu-bar-tabs-how-to-hook-the-menu-button-to-showhide-a-custom-tab-bar/
It's thought to be used as a replacement for the menu, but I believe it's also great for a custom button bar. I'm actually gonna integrate it in my app straight away :-)
Kudos for androidworkz, the original author.
I think the power control widget does what you want. Looking at the source for the widget, it uses a combination of LinearLayouts & ImageViews to achieve the layout.
