I have an application with three tabs. Through various interactions with the items in the tabs I end up launching other activities. The client has reviewed this and would like the activities launched "within" the tabs, so the tabs remain visible and if the user clicks the tab it goes back to the original activity defined in the setContent function. Is this possible and how would I go about this from other activities? (ie the child activities, not the one that defines the TabHost and has access to call setContent)?

Then calls useless Activity such as ThirdActivity or Second Activity.In this case, is my manifest.xml correct?Or, do I need to set another property to Second and Third activity? If so, what is that?I wonder manifest.xml file is right for my case.
View 3 Replies View RelatedI want to make an android application that shows a listing of applications (downloaded from the android market) and launches the one that the user selects. From what I've read, I'd have to use intents like this:
Intent intent = new Intent();
intent.setClassName(packageName, className);
startActivity(intent);
I just want to be able to launch the applications, not a specific activity that they could have.
My question is: How could I launch these applications if I don't know their packageName or className? or maybe, how could I get to know their className and packageName, if it's a closed source application that I didn't develop.
how to call BarCodeScanner, and return the value to a field.so now, i have a toast that says "successful scan" and then i want to pass the result to a new activity. when i comment out my intent, everything works (minus the passing of data/switching of screen, obviously) but when i run my project as is, it FC's no errors reported by eclipse in code or xml. any insights?

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?

As the title, I want close the TabWidget where some tab is selected.
I have a little problem, I'm doing landscape layouts and I can't resize the Tabs, which are huge like on this .

View 1 Replies View RelatedIn 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.

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.
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?
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:.......................
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?

I have written an application which calls native methods through JNI. In the native library 4 threads are started. On USB removal, the application is to be closed including the native threads. Upon receiving the USB removal event, we are trying to kill the threads (pthread_kill() ) and then finish (using finish()) the activity. After reconnecting the USB, the application is not launching due to memory corruption. In DDMS, it shows the threads are still attached to bionic. As the threads are not closed, I feel the resources were not released properly. If I reconnect again then application launches and works fine and the same repeats on every launch.
To solve this problem Can I use System.gc() ? Can I use pthread_exit() 1st and then pthread_join instead of pthread_kill ? Whats the procedure in Android to kill the native threads and also the application ? After the application is closed, will it not be listed in DDMS ?
I know this has been asked a lot of times in StackOverflow already, but I haven't quite found a solution yet. My app sends an email with a link in it that when clicked should launch the app. According to @hackbod, the best way to do it is to make use of the Intent URI (see this). Here's my code that sets the intent and puts it in the email body: Code...

View 3 Replies View RelatedI have two activities.A and B. A starts B.Both are running in the screen and both are visible. Say now B is visible.
On a special key press, I want to bring the A to the front and make it active. The problem I am facing is when the special key is pressed, another instance of A is launched and the new instance is brought to the front.
But I want the original A to come to the front. I want to make this change in the framework layer rather than application specific by using the singleInstance theme in the launchMode in AndroidManifest file.
I would like to know if I can launch a program via incoming MMS/SMS? More on the MMS side of things.
Workflow:
MMS sent to Android device
self executable MMS
Any thoughts?
