The main screen of my program has a number of icons that I set dynamically, due to that number can be different according to some parameters that I have in my database. To achive that, I use a gridview and it works perfectly.
But now, I need to change this main screen to behave as the home screen, I mean: I want to be able to drag and drop the icons to everywhere in the screen and also I need to be able to set my custom widget. The only thing I don't need is the flinging gesture.
Any idea how to start?
I tried to take a look to this sample (http://developer.android.com/resources/samples/Home/src/com/example/android/home/index.html) but I couldnt get how it works.
Thanks a lot

I am making an app for a dual display device for 1:1, face to face consulting.
Basically, the secondary screen is not clickable. So, what I need to do is implementing a presentation.
But some activities are sharable screen. So, it must be clickable in both screens. By default, the second screen is not clickable, but the second monitor displays the same screen. For making it clickable, I need to implement the presentation class for it. However, it will take a lot of times to implement it. So, Is there any simpler way to share the second screen and clickable?
(In presentation, the views are clickable/scrollable/etc)
I am not the best at android programming so please correct any errors I make.
According to this developer.android.com.
Android view is:
This class represents the basic building block for user interface
components. A View occupies a rectangular area on the screen and is
responsible for drawing and event handling. View is the base class for
widgets, which are used to create interactive UI components (buttons,
text fields, etc.).
However, I have not found an article about how to get a full view. I mean as in an entire screen as a view. The image I used below is to show what I want to include in that view. I want to include everything on screen. Everything On that Screen. (I can't repeat enough). It includes the chat heads, background, and menu bar. Everything that is on screen.
I can't figure out how to get a view like that from a service or from an activity. Any help is appreciated. I don't have exact code because I don't know how to do this.
Edit:
I know that I am very bad at explaining, so if you are confused, I am going to explain what I want to do with my view.
So basically, I want to make a screen tapper that taps for you so you can king of "cheat" games like cookie clicker. Therefore I need a view that contains the entire screen so then I can fake "touches" on the screen.
Hope this cleared any confusion
So you have a few things to deal with. Generally, the menu bar (and possibly soft-key buttons on the bottom) will remain visible. However, you can hide the menu bar:
hide the top menu bar in my android device & Tablet
You may want gestures to allow users to see it. Or, since it appears you are building a game, you just leave it hidden until they hit "home" or "back" or "exit" or whatever.
The "chat heads" are a horrible idea, but some developers think they are awesome. You can see more about that here:
Creating a system overlay window (always on top)
You might find something like this will work (but if new notifications pop-up, it may not help):

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.
I am trying to make an application for android that is based on IPAD app. I want to keep the same look to the app, but I am not a very good designer. So I was wondering if it was possible to for me to crop say the entire header and then have an invisible button or something on top of portions of it. so the design would become a little bit easier. Also if that is possible how would I get the what ever the event item is going to be to overlap with a portion of the image if it has stranger orientation. (I think I could fake this by just moving it closest orientation and extending the size untill it fits, but it would be nice to find a better way.)
How would I go about that?
I tried making the button invisible, but that did not seem to work.
Thanks in advance
I got lost on your description. But if you want to make a button invisible, calling setVisibility(View.INVISIBLE); will not work, because it will not receive click events. You may want to set its color to transparent instead. try using:
button.setBackgroundColor(Color.TRANSPARENT);
I am making a quiz application in which i am planning to use the SlidingDrawer control for displaying different question numbers. Clicking on a number will allow the user to jump to a specific question.
I have implemented the sliding drawer control but it is able to display only 6-7 buttons inside it depending on the screen size. Trying to add more buttons to it gives an exception.
I tried using a GridView inside the SlidingDrawer but i keep getting an error.
Is there anyway i can have around 20-30 buttons inside the SlidingDrawer control arranged in a grid like manner ?
Please give suggestions on any other way i can implement similar functionality in a way that doesn't take up much screen space ?
Yes, it's possible, as a matter of fact previous Android versions (1.6 if I'm not wrong) implemented the application Launcher that way.
Search the source for that version and you'll have a working sample.
