I have a login page which has a Advanced button. The button sets a view where a user can add some information. When I click save, it goes back to my main view (loginpage) and all info is cleared? How can I save the state of the first view when navigating away and then back to it?

I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.
I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?
I want to populate a table, defined in layout xml file through the programmatic way. I have define Table with a single row defining its header, with all the attributes set. Now i want to know a way so that i can just replicate that header row in the table with new content.
I tried using inflator inflate(int,view) method, but at runtime it showed up with error.
Here is the XML code for the layout file defining the table
CODE:.................
I have the following XML code:.................
The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.
How do you align views relative to the "middle" part of another view? I think it is best explained with a pic of the UI I'm trying to create in android.
View 2 Replies View RelatedIs there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

What is the best way to do this in Android? At every click i create a new intent associated to an activity and i do startActivity(intent) so that i can be able to go back with the Back button of Android. Is it the good way or is there a better approach? I would like to navigate onward and backward of n-levels.

View 4 Replies View RelatedI just got a new Verizon Android by LG and it came with no manual. I mean there was something, but it was so basic, that it was practically useless. I kind of learned how to move around things and how to make it work, so now I have some concept how to work with my phone. However, there are some things I cannot figure out.
Is there a manual how to navigate and customize the appearance of the OS?
For now I have two simple questions:
1. There is a system bar with some icons on the top of the home screen. On the left there are three icons:
(a) one red with a white person in it,
(b) one with a sheet of bent paper going into something, and
(c) one I don't get and which came up right now - red phone handle and a white arrow bouncing of it. And the last one is puzzling me, because it just came up.
Is there a manual that explains all that?
Another thing - I am getting beeps every once a while, telling me that something is happening. I look - sometimes it's a missed call, sometimes a notification on Facebook, sometimes a new message, and sometimes it is something I have no clue where to find it. I really need a manual. Badly! Plus the phone goes black and locks after one second all the time, even when I am still not done with things, and makes me have to unlock it too often. Is there any complete and comprehensive manual that really teaches me how to use and customize the system?
My program creates a sqlite3 database. With the emulator I have been able to use adb shell and get to the file in /data/data/<package>/ databases/<database> to inspect data. But with a real phone, I just cant seem to find that file. I get some permission even doing an ls on the data directory. Any idea what I need to set up to navigate the filesystem?

View 2 Replies View RelatedI'm having trouble to figure out how to bring the paused Task back to foreground. As far as I understood, when I click HOME button while a task is running, the task will be paused (onPaused() of the current top-level activity will be called,right?). I think there might be a way to bring this paused task back to foreground since the task is still ALIVE, but I don't know how. Do I have to put some more codes in the activity (I mean the one that is paused)?

View 1 Replies View RelatedIt seems as though the Android Market is not showing some apps.

Going forward will Android maintain the sites for multiple SDKs that might be in use. For example at this very moment there may development teams that are working on 1.0, 1.1 and possibly 1.5. If the main site carries documentation only for 1.1 (current release) will Android make an effort to make the documentation available online for both 1.1 and 1.5 simultaneously when 1.5 is released? Or the online docs only reflect the current release?

View 2 Replies View RelatedAbout the only thing I miss from my old WinOS phone is the arrow keys on the keyboard. I don't see that on my Dinc. So, how do you navigate inside a text field? If I want to correct a letter in the middle of a long piece of text, how do I get there? Currently I am using my big fat finger to try and place the cursor where I want but that is certainly not very accurate and usually takes several tries to get it where I want.Earlier today I was editing an email addr in contacts and the long text exceeded the text window. I couldn't figure out how to even see the beginning of the text.
View 3 Replies View RelatedThis may be a silly question, but is there a way to slow down the 'female' voice on the Navigate app? It talks way too fast, (no reason to) and mispronounces street names.
View 3 Replies View RelatedWith Google's voice action (or voice search), I can use the "navigate to" command to start the navigation app directly. However, this seems to work only with address, name of places.For example, I tried "navigate to 1234 main street" or "navigate to san jose airport" or "navigate to Starbucks on oakland road". The commands were recognized in all cases. For the last one, it prompted me with a list of choices for the end points, and once selected, proceeded correctly with the navigation.
However, if I say "navigate to John Doe home", although it also recognized the command correctly (i.e. it came up with the prompt "navigate to john doe home" and asked me to choose "go" or "cancel"), it would not come up with the correct address from the contact list as the end point to navigate to, but instead it would come up with a list of end points not related to John Doe at all, even if I have John Doe in my contact list (with the home address).
I googled around and it appeared that other users have also experienced similar problems, with some dating back 2-3 years ago. I just discovered this since I just switched from iPhone to a Samsung Skyrocket (with Gingerbread v2.3.6). Seems to be a simple problem to resolve. I can't believe that this problem is not (AFAIK) getting the attention of Google as I think this would be encountered by a lot of people.
Also I am wondering if there is a way to get around this beside giving the full address in the voice search command.

View 1 Replies View RelatedI am using an LG Enlighten, not as a phone but simply something to connect to hotspots with, check my email, and such things. Since I was not doing anything vital with it, I didn't put much thought into backing anything up.
Now, irritated with the default web browser, Bing and suchlike, I downloaded a bloatware remover and deleted the browser, along with two or three programs that looked like Verizon bloatware. As it turns out, one of those was my home launcher.
I did back these apps up in the program itself, but that isn't much use since I can't even access the program without a home screen.
I realized what had happened when I pressed Back to get out of the app. Instead, it went to the last app I had used. And then the one before that, and before that, and so on. I tried to keep pressing back until it would take me to the market, where I could open up the bloatware removal app and restore the backups, but eventually I came to a black screen where I could do nothing at all.
I turned off the phone, and was unable to turn it back on without performing a factory reset. Now, the phone goes to the Activation screen, and I am able to connect to USB, but that's it. The escape sequence won't bring me to the home screen - the launcher is apparently still gone.
Is there a way that I can restore the home launcher?
Last week I started using LauncherPro Plus - excellent app and everything has been working well. until I installed Beautiful Widgets this morning.
1. Takes a long time to navigate from one menu screen to the next, often with a FC due to timeout.
2. When the widget finally appears on the Homescreen, it can't find my location (yes, I've tried all combinations of geolocation, GPS, town search, etc)
3. Weather will not update and the moon is always showing even though it's midday here.
I was so impressed with the skins for Beautiful Widgets - it's the last thing I need to complete my custom look using LauncherPro, and I'm very disappointed that they don't seem to work together
