I 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 wanted to make a special ListView for android that has the springy bounce effect like what they have in the iphone,
Before I divide into coding it, can someone from google tell me whether that's possible if I just modify the ListView class or do I need to modify some other classes also?
For some reason, whenever I scroll through my list of items, the background inside my listview disappears and reappears giving rise to a "flicker" effect which I don't really want. I've tried the suggestion at: http://stackoverflow.com/questions/1377336/android-make-listview-transparent but it doesn't work for some reason. Any suggestions?

View 7 Replies View RelatedI wanted to see if I could change the top/bottom wrap fading effect seen on most long scrolling components. In this case I would like to change the color from black to whatever color I desire on a ListView.

View 3 Replies View RelatedI have a ListView whose position should be changed automatically along with the data. So, when the adapter's data has changed (adapter is calling notifyDataSetInvalidated), I'm calling setSelection. This has no effect. If the call to setSelection is done later (e.g. in a click handler) it is working.
The second problem is, that the ListView maintains the scroll position of the list although the data is completely invalidated, that makes no sense IMO.
It looks like a call to layoutChildren before the call to setSelection does help in this case, but layoutChildren is protected.
What is the correct way to do this?
What is the name of the view that is used to display options in the latest android contacts app? It's the one that after clicking on a contact picture slides in displays a few options in a horizontal line.

It's on the i phone market and I'm trying to see if anyone else has it or knows where it's at. It makes a sound like you would hear in an old cartoon.. boing, boing, boing.. like a ball bouncing or something.
View 2 Replies View RelatedAnyone else experiencing what seems to be a very poor responding touchscreen? Things like trying to flick between screens ending up with the home screen 'bouncing' but not changing. Or having difficulty moving icons and widgets to where it takes multiple tries to be able to move something on the screen or delete a preinstalled widget. Or flicking up or down in Contacts moving the screen just a few names (I got a rapid 'fly by' just once and have not been able to recreate it, the contact list on my old Voyager works much better). Or an unlock bar that seems to fight you if you move too fast. Or that seems to get worse in many of these after you do anything, e.g. if you add an app or move a shortcut icon then the screen response gets worse until you let the phone 'rest'. And all this occurs even with data disabled, Wi-Fi and GPS off, etc.
Maybe it is just us being bad at using the screens, but we also seem to be getting poor battery life. Are there some running services that might be causing all this? Would a Factory Rest potentially help? Any other ideas? Or is it time to see about a replacement? Factory Reset did not help with touchscreen issues, but may have helped with battery life.
My signal at work is about -100 dBm on average, funny thing is the bars go from 0 to 4, they just randomly bounce around every 10 seconds or so.
anyone have a solution to the bars moving? I thought the X was supposed to have better signal than the Dinc i just took back, but it looks like it doesnt, it just tries to say it does with the higher bars.
The incredible was getting between 97-103 dBm just like the Droid X.
My contacts are all setup as area code+xxxxxxx. I'm using the stock messaging app on my Moment. I get a text from someone in my contacts and reply to it. The text bounces back as not being in the ten digit format.
Is this because of the way the sender has their number configured or have I failed to setup texting correctly?
I called Sprint and they suggested a hard reset but I think the rep was clueless.
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 1 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 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?
I have 4 buttons in a horizontal linear layout. I'd like the right edge of the 4th button to align with the right edge of the linear layout (equal to screen width) I've tried using android:layout_gravity="right" but it doesn't work - the right button is to the right of the 3rd one but not right aligned . Am I missing something obvious?
main.xml with only the relevant layout params only is:
CODE:....
This doesn't seem to match the stated behaviour for layout_gravity in the SDK reference :"Defines how to place the view, both its x- and y-axis, within its parent view group."
Does ICS (Android 4.0) effect RAM/CPU usage of NEO V?
Does it increase or decrease?
There must be a way to do this. How can you tell a ListView that has a header to not scroll it when the user scrolls the contents? I want it to stay in a "stuck" position so that the user can always see what column the content applies to.
View 9 Replies View RelatedYou've probably seen the effect on the iPhone when you go to the next screen, it flips the screen, making it appear, like you just flipped over a card and a new screen appeared. There is a demo of something similar in the APIDemos (Views/Animation/ 3D Transition), but the transitions are between elements of the same page. Is there a way to implement the flip effect between Activities (in the same process)?
View 4 Replies View RelatedI tried the following from an activity:
@Override public void onPause() { super.onPause();
postDelayed(new Runnable() { public void run() { mTextView.setText("I am paused!"); }, 10000); }
The activity, while in the background, still executes the runnable. Is this incorrect? Should we absolutely call removeCallback() from our onPause() handler to ensure that no postDelayed() runnables execute if we get paused? Or is it necessary to do this only in onDestroy()?
I have an application containing 3 interfaces(each one occupys a screen), I want to switch different interfaces by touching on the screen. Just like the desktop has 3 parts, we can move from one to anohter by touching. Can anyone tell me how to implement the kind of effect or where is the code of Android desktop slide effect.
