I have an image and I've included it as an ImageButton (but ImageView would probably be fine as well). It looks like soemthing that is to be dragged up, in order to switch to the Settings interface. I've been researching this for days, looking at lots of pages on the question (many of them concerning ViewPager), but none of them was clear - some of them say "use class X", others just assume I know tons of things I don't. There was a few ones that actually worked, but they were horizontal. The vertical ones I found were incomprehensible and unexplained. Can anyone explain it in an understandable manner, please?
Basically what I need is:
I have layout.xml and layout2.xml;
there is an image on the bottom part of layout.xml;
as the user slides that image up, layout2 comes from the bottom;
If the user went past 50% (or something like that) when he released the image, it slides all the way up. If the user was at or before 50%, it goes all the way back.
Android has a built-in widget called a SlidingDrawer to do just that. In your case, the image at the bottom of layout.xml would be considered the "handle," and layout2.xml would be the "content." The handle can be any type of widget, be it a Button, ImageButton, ImageView, etc. If you touch or slide the handle, it will slide to cover the screen as you described.
The Android documentation in the link above explains it pretty well, but I can try to explain a bit more if you have specific questions

The idea I'm having is having a view that can be pulled down on top of the current view, with similar animation features like the one you can pull down from the top all the time, on Android Devices.
Here's an illustration:
The idea is to grab it and being able to pull it down on top of the other view, and then being able to interact with that view. To slide it up again, you should grab the bottom of the view (the grey area in the illustration) again, and then pull it up.
I haven't even worked with animations before but I found a lot of topics on that, while searching for solutions to my problem, including this: Slide down view in android
but my impression is that, that is about making animations when the user isn't touching the phone.
What is the best way to do this?
Is there a better way to do something very similar?
EDIT:
Here's the topic that made me find the solution: How to make an Android SlidingDrawer slide out from the left?
And here's the solution I used:
SlidingDrawer Top-to-Bottom
You could use a SlidingDrawer, this is a built in component into Android, but as far as I know it slides only from bottom - up.
If you a comfortable to modify your app design, then this could be an option for you.
However, on internet are some libraries of custom SlidingDrawer that lets you put the marker on any side of your screen, so you can drag it top-down, left-right, right-left.. any way you want.

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 am making an app that should implement a slider menu like the one in Spotify (where you slide the triangle in the middle to show the current playing song). The problem is I can't seem to figure out a decent method of doing this. I tried it with a Facebook like menu I found here.
However that just provides me with 2 linear layouts which are placed next to each other and are basically stretched or unstretched when expanding the menu. This gives some layout issues when expanding/collapsing (all items are placed below each other in the linearlayout when expanding and are quietly moved into the right place when collapsing the menu again).
In Spotify on the other hand it seems as if the layouts are on top of each other when the menu is expanded. This seems like a much cleaner way. However I have no idea on how to tackle this and Google doesn't really provide a lot of answers. Physically sliding the menu up isn't necessary, just getting the layouts on top of each other with some sliding animation on clicking the menu button.
Sorry for the long post, it seemed necessary to specify the question.
You dont need to re-invent a view or do anything fancy to get this functionality. Its called SlidingDrawer and is already available in the framework. Read this and this or watch this video.
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 found a nice feature in Dolphin browser that brings another window from the side on a side-swipe. It's like the window is connected and revealed by swipe. See image below. Anyone knows how it is done?
I might be wrong but my guess would be they use a SlidingDrawer set to a lanscape orientation in a portrait layout (so it comes from the side rather than the top/bottom).
EDIT: Ok, I see now - I was rushing to go to work and didn't pick up on the fact the left hand side is displaced.
I suppose you could use two opposing SlidingDrawer views and force one to be initially open and the other initially closed. If their 'handle' views were identical and overlapped, then the effect would be similar to what you are seeing.
I'm not sure if the 'purists' would approve as the SlidingDrawer is meant to be used in an overlay fashion, i.e., it is meant to cover an existing view rather than to appear to move another out of the way. Then again, I've been coding for many years and often go on the principle that if it works why not use it?
