Android :: Adjusting Contents Of ListView At Runtime
Feb 8, 2010
I currently have a ListView being filled by a custom Adapter with content it gets from a JSON string on a web page. The ListView's row layout is a LinearLayout that has two things in it, one AdMob layout and one TextView. The AdMob layout's visibility is by default set to Gone.What I want to do make every 5th row's AdMob layout visible. The current way I am doing this is by Overriding getView in my custom adapter (something I already had programmer to get my rows to have alternating colours), within this I keep track of the position variable and see if I have moved down 5 rows yet. When I have I find the AdView object and set it to visible. This works fine for a while but for some reason as I scroll down more on my list the ads become every other instead of every five. This doesn't make any sense to me because I have set up logcat to tell me when it reaches my "make ad visible code" and according to that I should not be having double ads. Has this happened to anyone else before? I'm not quite sure how to handle this situation.

1) I am developing my app in Eclipse 3.4.1 with Android (ver 1.1_r1) plugin. My app compiles and executes without errors when using the Eclipse IDE.
However, when I export my app (unsigned) using Eclipse (via {select project} >right-click>Android tools>export unsigned application package), sign it, and try to run it on the Emulator, it throws a runtime error when I try to update my sqlite database, at which time the specific error created is: SQLite error#14, unable to open database. It is able to read from the database without problems. (I have also verified that the database is: open, is not readonly, is not locked by another thread, is not in the middle of a transaction.)
I have limited experience, but this seems more like a "system" problem given that the app works OK in Eclipse IDE but then fails as an exported/signed apk. Some googling of SQLite resources revealed a similar error on a non-Android platform which was fixed by: "Set your permissions correctly on /var/tmp, or whatever directory you are using to hold temporary files".
Does Android have temporary files, and if so how does it handle permissions on temporary files? Is there a way to check or set these permissions to see if this fixes my problem here?
2) Not sure if it is related, but after I have run the exported/signed app which causes the runtime error, if I reboot the Emulator, and try to run the program using the Eclipse IDE , the program fails with the same exact error. PLUS I also noticed the following error message while the program is installing/running: 03-01 22:22:29.282: ERROR/PackageManager(53): Package com.northwestradiology has mismatched uid: 0 on disk, 10019 in settings; read messages:
I can restore the Eclipse version of my program to be able to execute without runtime errors by utilizing the -wipe-data option for the emulator. But note that if I run my signed APK using an emulator created with the -wipe-data option, it still throws the runtime error listed above...

I am trying to create a menu that slides up from the bottom.It starts with the menu's view just visible at the bottom of the screen, and then clicking it causes it to slide up.I tried using a TranslateAnimation, but although the pixels move, the hit areas of the menu are in the same position as before.So I think that if I can adjust the menu's margins after the animation is complete, this will accomplish what I want.However, I can't figure out how to adjust the margins.I've tried to create a LinearLayout.LayoutMargins object and then set its margins and apply it to the menu's view (which is a LinearLayout), but this doesn't work.

Recently, I have been interested in the android platform, especially power management. And then I tried to find the settings about cpufreq, but in vain. I really want to know if there is a way that we can modify the cpufreq governors within my application over the framework api.

I have an application which is designed for a fixed screen size.But when i install the application on a device with different screen size ,i am not able to view the complete application.Is it possible to allow layout adjustments based on variable screen sizes? like setting width with some % of screen size which is decided when application installation is done.For eg: 60% of screen size or 60% of relative layout

I know you can apply Permissions for Applications on it's manifest.xml file. What I want to know is, can those Permissions be adjusted by the Applications on the fly?Here's my reason: say I have an application that is allowed to do "x", "y", and "z" (SMS, sockets, etc) Permissions. Now lets say I have a logical "user" that connects to this Application, and I want that user to only be able to do "x" and "y", but not "z" Permissions. It would be nice to have the Android Framework handle that instead of having a bunch of "if's" in the App code.

An app or mod that will use the microphone to sense the amount of noise around you and adjust the notifications accordingly - that is to say when its quiet, next to my bed and I am sleeping I want it to be all quiet sounds - but when I am working and there is fan noises and other stuff that is louder then normal I want the notifications to be loud - but if I walk into the break room which is quiet I want it to be quiet again - or if I am listening to music in a room or car turn up the notifications so I can here them and back down when not. You know take a sound reading and turn up or down the volume of the notification that is happening at that given time.
Only problem being when its in your pocket it will always seem to be quieter then normal so they will be quiet also, so there would need to be something to listen to the sound and determine if its being muffled by a pocket or whatever and turn it up then - if playing a sound and analysing that sound it should be able to determine what environment the phone is in, like a pocket or bag that will make it quieter. I am not even sure if i am describing this properly but I know someone can probably figure it out, but it might have to be something the manufacturer does, like that phone that has 2 microphones to auto cancel out background noises like a bluetooth headset.

I'm using the FontFitTextView that was posted in this other thread, but it isn't working exactly right for me. The measureText() call is returning a number that is obviously too small to display the string. When it runs through to find a font size that will allow the text to fit, the font size it settles on is still too big. I feel like there is some other kind of padding or margin or some other invisible that is contributing the math that makes up the width which is causing the discrepancy.For example I want to set the text of my FontFitTextView to be "10,000.25".The width of my FontFitTextView is 96 pixels, with 8px padding on both sides, so my available width is 80 pixels. The call to measureText() says that the text "10,000.25" is 64 pixels wide. This means that the current font size should be small enough to display the entire string. However, when the string is actually drawn on the TextView the last 2 characters are chopped off and all I see is "10,000." instead of "10,000.25"

I did a search but did not find a specific answer to my question:Is there an app/widget to toggle the media volume from mute to ON? Or some other shortcut method to adjust the volume and/or mute the media volume without having to first play media?Another thread said that there was an app for it but it did not state the name and I could not find it on the market.

I am used to being able to take my current position on a map or point to a position and set it as a contact's position. I can't seem to figure out how to do this on the DROID.Even though it is still a bit buggy (beta and all),I love the application, but I have noticed that specific addresses can be off by a block or two.I would like to be able to tell the phone that the correct position of this address is here.

Problem discovered while installing Navfree. Got the error message "not enough space". I cant move it to the SD card or anything as I can't install it even.
I have 25Gb of available space but less than 2Gb for apps? I'd like to use all internal storage for apps and the external card for media. How I set that up?
I have a Galaxy S2 Epic (SPH-D710) stock ROM, rooted with the zermax kernel and fited with a Sandisk 16Gb class 4 micro sd card.
Settings>Applications>Manage applications>All
112Mb used of 1.9Gb available.
Settings>Storage>USB storage
Total space is 11.5Gb and Available space 11.5Gb
Settings>Storage>SD card
Total space 14.83Gb (aka 16Gb!) and Available space 14.81Gb.

I entered some appointments prior to a business trip in another time zone. When I arrived in the new TZ, the calendar shifted all my appointments by 6 hours, so a 9am meeting was shown at 3am. How can I set an appointment at what will be the local time for that event and not allow the calendar to adjust it?

Has anyone been able to adjust the amount of rings on their phone? My phone rings about 6 times before it goes to voicemail but my girlfriend's phone rings only 4 times. I brought both numbers over from T-Mobile where they each rang about 4 times but now w/Verizon mine went up to 6. Tried calling tech support about it and they said there wasn't a setting for this on the phone itself and they gave me an answer like some phones just tend to connect to the network faster.

Until now I had my screen set to auto brightness.First, +1 to those who said in other threads that the screen looks even better when you turn that off and put brightness all the way up.But my question here is why, on auto brightness, the screen sometimes increased or decreased brightness when I was using it. It happened all the time. The only thing I can rule out as the cause was time delay, because sometimes it happened as I was typing or just after, and sometimes it would happen after a delay. I think it must be connected to either orientation, or movement, or brightness sensor detecting the ambient light, or something.If I could figure out how to make it stop doing that I would go back to auto-brightness.

I did the OTA upgrade to 2.1 last week, and noticed that the "click" when typing on the keyboard is really loud now.I notice this mostly when texting, which I do at work, and now it's so loud that everyone around me can hear.So, the question is how to adjust the volume for text input? I can't for the life of me figure out where this setting is. I have looked through all the menus but I guess there is one that I havent found. I also looked in the Handcent app menu and there's nothing in there.Also no adjustment in the standard text program either.

Before rooting my device I had read there's the possibility of adjusting the permissions or even feeding false data to apps.
Today I found such an app to allow me to do so.
Both xposed apk and xprivacy ! I downloaded both which is needed. Anyway before configuring to operate there was a warning to have backup of whole system and know how to recover. Further warning said there was possibility of soft brick and bootloop. I immediately deleted them both. So did I do the right thing?
