When we touch a Button in android, the button highlighted(background turns yellow). This visual change is very friendly to users. I want the same effect on a View object(for example a TextView or ImageView) but I can't figure it out.

I have need to make a sort of "Pie Chart"-style circular display. the wedges of the chart have to be touchable, and the whole circle has to be able to spin 360deg. I'm still an android noob, but I'm guessing that I can't do this with a Layout.. right? preferably, the wedges would be image assets that I create in Photoshop, and not programmaticaly created does anyone have any Idea where to start with this?
View 1 Replies View RelatedWe are currently looking into methods how to implement tabs. TabHost has serious limitations and is no option. Instead, we are experimenting with our own tab solution, which has its own task (activity stack) for each tab.
It's working well except that there's transition animation performed by the system when launching a new task the first time. The NO_ANIMATION parameter passed to startActivity has no effect in this case. The animation breaks the app visually - is there a way to prevent it?
I have an XML layout with some custom tabs, a heading, and a ProgressBar(main.xml). I wish to add another XML layout(home.xml) to the main.xml layout, as i wish to keep main.xml re-usable for other activity's layouts and simply add things to it as necessary.The problem: after inflating R.layout.home into rootLayout, it seems as though the ProgressBar contained in rootLayout is hidden underneath the content of home.xml.Is there a way to tell certain views(via XML) to float above other views when the layout is constructed in this way?if not, am i forced to use methods such as progressBar.bringToFront() to raise targeted views to the top?what alternatives do i have in z-ordering views when some layouts are constructed using inflation?
View 2 Replies View RelatedI developed an activity that extends the ListActivity. It has a ListView that binds to a DB. Thing is that I can click on the items of the view only with the trackball. When I try touching the items or the view I can't, is not responsive. Below the view I have a button that works just fine in touch screen mode. I already tried removing the button (I thought that was it) but no. Code...
View 4 Replies View RelatedI am creating a small calendar control that will be part of an application that runs on a larger-than-phone-sized screen. The calendar will simply display the current month and allow users to touch-select a day with an iPhone keyboard style popup bubble indicating which day is chosen.
The problem is that in order to do it with buttons would require 42 tiny buttons, which would probably be a resource hogging solution. Although a keyboard would give me the iPhone-keyboard-bubble-like behavior, i dont think that we can place a keyboard in a static location within a Layout, using it like a View.
So I am wondering what is the best way to go about implementing this. Is my "42 buttons is too many" assumption correct? Is my keyboard assumption correct? Do I have to use a SurfaceView (or something) and draw everything myself? Is there some other grid-like control that can make this simpler?

View 6 Replies View RelatedI have a GridView of 9 rows of which the first one is sort of "header" row.As there are 8 more rows they flow beyond the end of screen and need to be scrolled down to.However this scrolling also causes the first row to go "off-screen".Was wondering if there is any way I can prevent the first row alone from being scrolled off?I dont want to make this a separate LinearLayout as it is part of a dynamic View (the GridView) that I create at runtime.
does any one use ASTRO?i feel the tab view in this software is very nice and i want to imitate it. i find that this tab view is like TabHost,but the tab can sroll from left to right. this tab view is based TabHost or based gallery+imagebutton?

View 1 Replies View RelatedMy app, among other things, downloads and displays images from the Internet. Some might be too large and trigge an OOM when ImageView.setImage() is called. Of course, this normally makes the application to crash. I've put catch (OutOfMemoryError e) around the method invocation. I know that catching errors is unusual, but in JSE applications it proved to work pretty good, especially when the problem was due to image manipulation that consumed all the memory. The Android app seemed to survive for a while, but then it blocked the computer. All buttons are irresponsive, even though the phone seems still alive (e.g. it's playing the audio notification that new email has been spotted). I tried holding the power button, it triggered the shut down menu, but touching a menu option didn't do anything. Only after a while, the phone became responsive again.
Now, it's reasonable that one can't display everything on a smartphone; I'm sure there's some inefficient memory management I'm doing (perhaps keeping too many images in memory); ok, I have to improve my code. Given that I'll do, how can I add some safety facility to avoid the most severe consequences? Making an irresponsive application it's a 100% sure way to make people to uninstall my app and give bad reviews. I'm thinking of a two-pronged safety approach: 1) whether it's possible to understand in advance whether an image is too large to be rendered by itself;
2) whether it's possible to recover from an OOM in any case.

View 2 Replies View RelatedThe add/remove columns UI of TweetDeck android app is very promising. But I have no idea how to make one like that.
If I make it with HorizontalScrollView, and the children with layout_width set to "fill_parent" code...
I can't scroll horizontally and only see one view.
If I set the layout_width with number like this: layout_width="320sp" then the two columns sit next to each other and I can scroll horizontally.
Do you have any idea how TweetDeck makes theirs?

My activity has a set of buttons on the left half of the screen and a ListView on the right.Initially the focus is on the first button. When I browse the buttons by pressing DOWN arrow key and then press the RIGHT arrow key, the focus does not go to the topmost list item. Instead, the list item correspondingly on the right gets focused.Is there a way that when I press the RIGHT arrow key, the focus goes to the topmost item on the Listview?
View 1 Replies View RelatedIs there a standard way to add a footer to a context menu, in which I can add a checkbox to make the selected option the default one?
Similar to the context menu that comes up when choosing the default home screen for example.
From the Api docs for ContextMenu I see that you can set a header view, but not a footer view. Also the setCheckable / setGroupCheckable methods don't seem to help much here.
Does this need to be done via a custom (alert) dialog? I would be wondering if nobody has yet developed such a component yet in case it's not possible through the standard SDK api. Any standalone open source component out there (beside the Android source itself)?
I am making an android application that shows a list with users, I would like to add the image,name,status,and a button in every row of the list, just like in the androids 1.6 native caller-> favorites tab.Until know I have managed to add the image and name using an ListActivity but when I try to add the button the list becomes unselected.So I have 2 questions, first is the list mentioned above listviews or listactivities? also is this possible using listActivity? and second, what is the difference of the above mentioned classes?

I was looking at the Captivate and the iphone4 in store today and when comparing the same web pages in full page view the text on the Captivate was much smaller than the iphone4, even though the iphone screen is smaller. Zoom just made everything bigger so it wasn't in full page anymore. Is there a way to make the text bigger while in full page view? On a side note, that iphone4 screen is super sharp for text and the whites were much whiter vs the blueish tint on the Captivate.
View 8 Replies View RelatedSo I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file
View 1 Replies View RelatedI am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed.

The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............
