In my TabHost activity, I want to show an ImageView below the selected tab (the ImageView overlaps the tab content). What would be the best solution to do this?

In android how to close TabWidget when a tab is selected.
As the title, I want close the TabWidget where some tab is selected.
I am new to Android development, just reading docs and trying the APIs. I am quit confused how ImageView managed to draw just a part of its content after an invalidate(Rect) invocation.
I've checked ImageView.java, found no other drawing method except onDraw(Canvas), but onDraw(Canvas) only cut the drawable only if it is beyound the view's visible boundary. I also read the implementation of View.invalidate(Rect), I think the key of this function is calling to mParent.invalidateChild(this, r);
However, I think the parent view doesn't know how to draw the child in the given Rect, it finally has to call some method of it child to paint out. Has anybody investigated this part of codes? Would you please give me some guide?
Is there a way to show that a WebView item contained as a item in a ListView is selected? Right now the WebView does not seem to display its contents transparently like every other control so it takes up the entire view and does not show its state as selected.
Also, when the content of the WebView is selected, scrolling down with the track back does not seem to cause the WebView to loose focus. If I continue to scroll down with the track ball, all of a sudden an item in the middle of the ListView gets selected.
How to? The spinner not showing, but the imageview yes. When i click on the image, then the Spinner showing up.

View 1 Replies View RelatedI want to scale and display images which are dynamically loaded to a certain maximum size. The way I'm doing this is to set the layout_width and layout_height of my ImageView to the maximum dimensions and setting the scaleType to "fitCenter".
But here's the problem. This is inside a RelativeLayout and I want to show text directly under the image. In portrait mode, the text is way at the bottom (because of the height I have set). So I want the ImageView to scale down to the actual visible image size which is what it would seem like adjustViewBounds="true" should do.
Am I wrong in this assumption? Or is there a better way to do what I'm trying to do? Because I've been unsuccessful to this point!
I have build an application in android. This app needs to display a list of text, but the list of text increase continuously. It means user can see increased list of text. Each text is separated by a horizontal row. It looks like google market when market try to show list of applications. How can i do in this situation ?
View 1 Replies View RelatedI am using the webview control in android to show the html content. But I face a problem that in webview I have to fix the height so thats why if html content contains less data then it wasted the space. Is there any solution to solve this problem that how can I show only same content as html has in the webview without any wasted space please help. following xml i used to draw webview is this right? In this i give fix height to webview. if i am not giving fix height then it will show only 1 line data with scroll.

View 1 Replies View RelatedI have an application that targets the 1.5 framework and uses the default light theme. When using a tab widget with this theme, the tab images are barely visible, and the tab captions are quite impossible to discern, except for the currently active tab.In the default dark theme these tabs come through quite clearly, but this is not a solution I'd be very happy with. Is there a simple setting I can set, that sets up the tab widget for better visibility in light themes, or would I have to tamper with images and text styles manually?

View 1 Replies View RelatedI have a listlayout with items in it that looks like this:
There is first an ImageView (the light) and then two textViews. All of this inside a TableLayout. (source here: http://code.google.com/p/switchctrl/source/browse/trunk/android/res/layout/device_switch.xml)
I want to have a rotating animation of a loading indicator Ontop of this light when this particular device (light) performs an action or an action is performed on it.
How do I put an animation ontop of this light imageview?
In my layout xml, I have: <TabHost android:id="@+id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent">
<TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/>
</TabHost>
My question is how can I get a reference to TabWidget object. I tried this: mTabWidget = (TabWidget) findViewById(com.android.internal.R.id.tabs); but this won't compile since 'com.android.internal.R is not visible. And then I try change the id to android:id="@+id/tabs" but I get a run time error saying: "Your TabHost must have a TabWidget whose id attribute is 'android.R.id.tabs'"
I'm writing an android program in which I have an activity that uses tabs.Anybody have any idea how I can get this content into a tab without crashing my application? My actual program is more complex and has more than one tab but I simplified it down to this in an attempt to find out why it's crashing but it still crashes and I don't know why.If I don't use LayoutInflator my program doesn't crash but I don't get any content either, just tabs.

To support for the multiple screen i set the android:layout_weight="1.0". After that, I got this problem i added my layout code below. any idea to make the TabWidget at the bottom stably? Code...
View 1 Replies View RelatedI don't know what I did but for a period of time my TabWidget had white colored tabs which looked really nice. I never set a theme or background/foreground color in my project at all. The next time I compiled it it reverted back to the gray tabs. My application is using the default dark theme. Even if I set the application theme to light, the tabs are still gray. So obviously it was something else that changed the tabs' color. Anyone know how to do this?

View 2 Replies View RelatedHaving just moved to an Android 2.1u1 HTC Desire from an Android 1.5 HTC Hero, I've noticed that there a weird behaviour from TabWidget in that it shows a thick white line under the tabs instead of what I think it should do. Difficult to explain so here are two URLs: http://android.esstec.co.uk/images/how_it_should_be.png http://android.esstec.co.uk/images/what_it_is.png Initially the tabwidget looks like the first picture but when you do anything with it (change tabs for example), it looks like the second. These screenshots are from the Google provided API demos so I don't think it's my code, but I wanted to paste here before filing a bug. Anyone got any ideas?
View 2 Replies View RelatedIt seems that Android is very buggy compared not only to the iPhone, but to pretty much any other software. It's not just minor bugs either - pretty much every developer will come across many serious bugs. Some examples:
- When you run the "sdk setup.exe", the very first thing that happens is that it informs you that it can't connect using https, so you have to change the options to use 'http' instead. This appears to be a bug in the .exe rather than any kind of user issue because the https url works fine in the browser and this error seems to affect everyone. Sure, it's trivial to work around (just do a google search and you figure it out in 5 seconds), but the user shouldn't have to do that. It makes it look unprofessional.
- When you view a TabWidget in the layout editor it crashes.
- Every time you run an app in the emulator, it starts off with the screen locked so you need to press the Menu key.
- Various socket bugs (or perhaps all the same bug) related to IOException not happening. Even something as simple as just trying to connect to a remote host that is not listening will cause it to hang instead of immediately returning an error.
All of these bugs have been logged for months (some by me, some by other people) with no indication of any fix.
At the moment I'm just using the emulator, but I'm wondering if the phones themselves are this buggy or if all the bugs are just in the development environment and emulator.
This may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?
View 2 Replies View RelatedMy employer is having me work on an android application with very specific UI requirements. Specifically, we need an interface that looks exactly like a TabWidget interface. However, having the tabs on the left hand side is an absolute must. We aren't going to be deploying this application to any android phones, its for an in house device, and as such don't have any problem violating any design considerations that the android platform might have.
We already have a working prototype that hacks together the functionality we need using a combination of focus listeners and list views. It isn't pretty, and we aren't very confident in it just yet, but it works for the time being.
What we'd really like is to throw all of our prototype UI code away in exchange for using the built in TabWidget. However, since TabWidget is hardcoded to only work with the tabs on top, this isn't really an option.
So, we are hoping that someone out there has a patch, or set of patches, or perhaps a custom class, that handles the TabWidget functionality with the tabs on the side instead?
The relevant code for the TabWidget is here: http://www.google.com/codesearch/p?hl=en#uX1GffpyOZk/core/java/android/widget/TabWidget.java&q=android%20package:git://android.git.kernel.org%20lang:java%20tabwidget&sa=N&cd=1&ct=rc
And the specific function that is hardcoded for being tabs on top is
CODE:.......................
I am having a hard time understanding content providers. In the notepad example and others, the content provider never even declares its CONTENT_URI anywhere inside itself, yet the docs say to publicly declare this. It's declared in a different class. So when an activity queries a content provider with a CONTENT_URI, how does Android know which one I want. I see no link between a content provider and its CONTENT_URI declared in another class.
I also don't how to think about intents and content providers. I know that you don't call an intent on a content provider. But an activity queries a content provider without an intent, and an activity has a mimetype attribute in the manifest that would seem to tie it to a content provider.
When a TabWidget is using intents to designate the target Activity for each tab, is there any special handling of those Activities on the Activity Stack outside of the default operation? For Instance, if my app has tabs A, B, and C, and I click them in this order--A, B, A, C, A, B--how will the Activity stack change? My understanding of the default operation, if startActivity() is called each time on the intent, would have the Stack keep loading up new instances of the activities: A, AB, ABA, ABAC, ABACA, ABACAB It's hard to believe that's how it works though... Seems like it would be a waste of resources and could be endless. Can anyone tell me how this will actually work?
