Achieving a true "dropdown" effect (as seen in Adobe's Photoshop Mobile app for Android, image below) has proven challenging using Androids built-in methods.As others on Stackoverflow have told me, editing the style of a dropdown list view of an Android spinner is limiting.How is this dropdown effect done?

'm working on Boid for Android and we've run into a problem.
How do you style the spinner dropdown in Android 4.0? Whatever we've tried, it won't work. We only need to style it in the 'collapsed' state, not when it has the dropdown showing.
Is it possible to set the width of a spinner dropdown list in code? I have a spinner populated with integers, and it does not look good with the list expanding to full width. Can I set the width to wrap the content somehow?

On my device (Motorola Milestone) and in the emulator this looks like the standard gray spinner widget.
On of my colleagues uses a Motorola Backflip and on his device the Spinner is black. Now its very hard to read the font in the spinner.
What do I have to do to use my own view for the spinner? I don't mind to have the gray spinner on all devices, but it should always look the same on all devices.
I have an xml layout file which contains a few widgets including a Spinner
I want to display a list of strings in the spinner, the list is generated at runtime as a result of a function so it can not be in arrays.xml.
I tried doing:
CODE:...........
But this crashes my application.
I have a spinner 'aperture' set up with a list of numbers, and a spinner 'mode' with two options. When a button is pushed I need a calculation to run using various inputs, including the current selection from 'aperture' and a value derived from 'mode'. How do I call the value of a spinner so I can use it in a calculation?
Also, how do I use the spinner 'mode's selection to set this other value before implimenting it in the calculation? To be more specific, if the spinner is set to Small then the value I use in the calculation is 0.015, whereas if Large is selected I need to use 0.028
My other inputs are EditText views, so right now I am set up like this:
CODE:............
That is not the actual equation, it is just a test to make sure everything connects properly. How would I call the value of spinner 'aperture' and the Small/Large spinner 'mode'
I have a spinner widget in my activity which lets users pick a list name.
Normally, the function of the spinner is to switch between lists but for a couple of instances, I swap out the selection change listener to perform a different function with the same list of options. Once the selection has been made, the old listener is restored and life goes on.
This is a bad and buggy arrangement. Instead, I would like to have a function that just takes a selection listener and some other parameters and shows a popup list that's populated by the same cursor (or and identical cursor) as the spinner, without using the spinner itself.
Is there any way I can do this?
I am trying to populate a spinner depending on another spinner's selected item, my code is the following:
CODE:.................
what is intriguing me is that the first spinner onitemselection works perfectly ( I can see the values in LogCat) then when I change selection of the 2nd spinner I am gettging an error on this line: String selected= (String) s2.getSelectedItem(); So the compiler gets insisde then onItemSelected function of the 2nd spinner but throws an Handler exceltion on s2.getSelectedItem()
why? it works perfectly for the 1st spinner.

View 1 Replies View RelatedI have a MultiAutoCompleteTextView on my activity , the data for this view is provided by a adapter. There is a global theme for the app and applying this theme caused the drop down background of the MultiAutoCompleteTextView changed to white and text color is also white. To over come this problem I did the following to change the background of the drop down to black.The background of drop down is changed, but now when scrolling up and down , the items in drop down becomes blurry.

View 3 Replies View RelatedI am using AutoCompleteTextView and want to limit the number of dropdown items visible at a time on screen. Currently it fills up the screen but can i limit it to say 2 items with a scroll bar for displaying more.
View 1 Replies View RelatedWhen typing in an AutoCompleteTextView, when the list shrinks because the number of matches goes down, the DropDown leaves several "ghost" elements on the screen. This only seems to happen when an IME is visible, and visually, it appears to be limited to the area that shows the autocomplete suggestions for the input method, so quite possibly it's happening in what is part of the IME's layout. This occurs in 2.0.1, 2.1 and 2.2 emulators, and most likely on devices as well (confirmed at least on Milestone running 2.1- upgrade1). It _does not_ seem to happen in an 1.6 emulator.

In my android app I use AutoCompleteTextView and refresh items list for each 5 seconds. Refreshing is working, when I call notifyDataSetChanged(). But when I type here something and it'll give me the list of matching items and then I close it manually, when another thread is refreshing the list and calling notifyDataSetChanged() dropdown list is showing automatically (even if I closed it before). And it's really annoying, because if list is long it takes whole screen and after closing it'll appear in another 5 secounds. I tried dismissDropDown() just after calling notifyDataSetChanged(), but it doesn't have any effect. It looks like dropdown is showing with a little delay. It's also not good way to fix it, because if user hasn't closed the list it'll close after a refresh. Also tried to take focus away - still no effect.
So I need a method to: update my items list (via notifyDataSetChanged()) without automatically showing dropdown list, but if dropdown was already showed don't close it.
I'm trying to scale/rotate an image using setImageMatrix, and it seems to have no effect. I've done a lot of Googling and found some people mentioning similar problems, but found no solution.
View 2 Replies View RelatedI've created a custom toolbar using a gradient inside a shape. It looks very nice, but since we only have the option for 3 colors (startColor, centerColor, endColor) it looks very round. I would like to do a glass effect, which requires a sharp change in color in the middle. Basically I need 4 colors (startColor, justabovecenterColor, justbelowcenterColor, endColor). Now I could have two shapes sitting on top of each other to get this effect, but I don't want to do this. I'm getting into some tricky UI customization here and that would be very difficult to manage on different sized screens.
View 1 Replies View RelatedI was interested in making a springy-bouncing effect for ListViews similar to one in iphone.I wanted to make sure about a few things before implementing it.
1). Does Android provide this feature somewhere in the new Donut version thats coming out?(so that i don't have to re-invent the wheel)
2). Do Google plan to add this feature in any future versions of the SDK?
I am looking for Deep effect in Android gallery. i did some work around coverflow at http://www.inter-fuser.com/search/label/Coverflow but it also do scroll left and right. it does give me the idea to calculate offset top and left for each item separately but still there is no access. what i am trying to do is, when user scroll, images would scroll from deep behind the right edge to center and then to left side deep behind.i am wondering if anyone have some thought about arranging the imageView's on deep offset (something like V shape ) rather than on horizontal as it is.

View 7 Replies View Relatedthere seems to be a dead-lock problem when using sound effects with SoundPool. I was hoping the the problem would be fixed in the new firmware update, but unfortunately, it was not. The application still locks up after couple of minutes when playing sound effects using SoundPool. My application is a game playing a background music scenario with multiple simultaneous sound effects. Any word from devs as when we can expect stable SoundPool would be very welcome.

View 2 Replies View RelatedI found an interesting tip over on the Tmobile forum that helped me out. I seam to get a real strong halo effect in my pictures from any light source, that blows out large parts of the photo. Most likely you have touched the camera lens while changing the battery or fooling about with the phone. Solution clean the camera lens and the inside and outside of the back cover. It is still far from great camera but, man, made it a whole lot better. All this time I thought it was just the crappy camera.
View 1 Replies View RelatedI'm trying to create a custom widget which looks lick HTML table. I chose to derive from TableLayout, which is the subclass of ViewGroup and View. What's confusing me is that the drawing I put into my override of View.onDraw did not take effect, until I moved the codes to the override of ViewGroup.dispatchDraw. I know dispatchDraw is a good place to draw something, but I'm just wondering why there's such difference in my practice?
View 3 Replies View RelatedSo I have a Canvas which uses a bitmap to store the draw calls on. I have applied a ColorMatrixFilter to the underlying bitmap of the canvas. It looks awesome when on the phone and during the OnDraw calls. The ColorMatrixFilter is making the bitmap look exactly like I want it when the Canvas is drawn. Now how do I SAVE the Colormatrix effect? I normally take the underlying bitmap that is attached to the Canvas and Bitmap.Compress save it. But this method doesn't save the ColorMatrixFilter effect. How can I get the ColorMatrixFilter to actually alter the Bitmap itself so I can Bitmap.compress save the damn thing!
View 2 Replies View RelatedI am new to android development, also new to java. I have many years of experience with OO PHP, so it's not hard for me to quickly learn Java and Android, but I still don't know many things like Thread class. I just started developing a simple app. What I want to do is that when a button is clicked, then the TextView is update in this way: the background is changed to black (by default it's set to white) Then it should wait a half a second and then set the background back to white and update the text inside the TextView
Here is my code, it's inside my Activity class:
public synchronized void onClick(View v) { // TODO Auto-generated method stub switch (v.getId()) { case R.id.btnPlay: showNewDraw(); break; } protected void showNewDraw() { textResult.setBackgroundColor(Color.BLACK); textResult.setText("Before sleep"); try { Thread.sleep(500); } catch (Exception e) { textResult.setText("Something wrong"); } textResult.setBackgroundColor(Color.WHITE); textResult.setText("After sleep"); }
The way it works now is that it seems to actually take 1/2 second from the time the button is pressed and text is updated, but the background is not reset to black and back to white - it always stays white. Either it is being set to black and instantly reset to white or it's just never set to black. What should I do in order for the "delay" effect to work?
