[android help] CursorLoader with Cursor accsss inside a loop


I'm building a ListView, and each item in the ListView has data from several different Cursors. I've got an object which holds all the data for each item in the ListView. I'm using an ArrayList of these objects to populate the ListView.


The way I'm implementing it now, I first get a Cursor to all the rows in ContentProvider A. I loop through this cursor, adding three of it's fields to each object in the ArrayList. On each iteration of this loop, a new cursor is created to pull a field from ContentProvider B based on a field in ContentProvider A. This field is used to pull another field in ContentProvider C. So, essentially, there's lot's of Cursors being created, and the queries of subsequent Cursors are dependent on data from previous Cursors.


From what I understand, it is ideal to use CursorLoaders and LoaderManager to generate the Cursors in a separate thread and manage their life cycle correctly. I'm not sure how to translate this approach, or if there is in fact a better approach that minimizes the number of Cursors in the first place.

[General] Question about Luminous Dots live wallpaper for Galaxy S3


I just started using Luminous Dots on my Galaxy S3 and sometimes when it is on the lock screen the wallpaper rotates 45 degrees... Is it supposed to do that? I think it has something to do with the motion sensor. Any help is appreciated! Thanks!

[General] Where does Google Play Music store music files on the device?


I have music that is playable with Google Play Music player, but not with other players. I have chosen for the music to be "on the device", and it plays when even in Airplane Mode, so I know it is not streaming, but the music files do not show up in my "Music" directory tree, or under any other file trees that I can find. I have used ES File Explorer to do a top down search for some of the missing titles, but it doesn't find them. I'm perplexed. There must be a cache somewhere, but I can't find it.

[General] Note 2 n7105 can't surf on 3G or H+


I bought a Note 2 in Singapore and I can't use 3G or higher network. According to Samsung, although my mobile is unlocked they can't do it anything to solve my problem. Does anyone has a clue how to make this thing works. The other thing H+ sometimes is available, but 90% of the time I'm using E.

Cheers
P.S. it's not a carrier problem.

[General] camera swap


Is it possible to buy a phone...be it samsung, lg, motorola or whatever that has a 5mp camera and then buy a 8mp replacement camera from a nicer model and swap out the 5mp with the 8pm and have a potentially average phone with an amazing camera?

I swapped out the camera in an htc and it just snaped out and the new one snapped in but that was the same camera, it had just gone bust. So is whatever makes it 8mp vs 5mp in the camera itself or is it part of the components/chips built into the phone thus rendering a swap to a better camera pointless?

My situation...I have metro...and my wife keeping wanting to get an iphone...:-( because it takes such great pictures. I tried to appease her by getting her a sprint HTC evo and having it flashed over to metro...the prob is it keeps going into boot loops and runs much slower then it should. I have tried to trouble shoot but to no avail! Every time it goes a-wall my wife says she is going to go to AT&T and buy an iphone. So to avoid this potential catastrophy I want to get a metro phone...no flash=no bootloops...but with a nice camera...8mp like she has in her htc. But the only one metro has is $500 which is stupidly more then I would spend on a phone! Hence my dilema! I need a cheaper metro phone with an awesome camera...if you can think of any other way to accomplish this I am all ears!!

Thanks all! You know what they say..."happy wife, happy life!"

[android help] Using ViewGroup within custom component


I've created a custom Card widget for use in my Android application, as shown here:




android:layout_width="fill_parent"
android:layout_height="wrap_content"
style="@style/CardBaseTheme"
android:orientation="vertical">
android:textIsSelectable="true"
android:id="@+id/cardTitle"
style="@style/CardTitleTheme"/>
android:textIsSelectable="true"
android:id="@+id/cardContent"
style="@style/CardTextTheme"/>



Now i would like to make this widget more generic by replacing the second TextView with a ViewGroup component, so that I can define cards using:



android:layout_width="fill_parent"
android:layout_height="wrap_content"
app:card_title="@string/about_header1">





However, this doesn't seem to work. LogCat only states error inflating class android.view.ViewGroup, which doesn't really help me either.


What would be the correct way to do this?


UPDATE:


LogCat stacktrace here

[android help] Can all xml layout convert to java code in Android?

Can all xml layout convert to java code in Android? - Stack Overflow



















After developing few applications, I know that many people like to add view programmatic ally.
But is it all xml layout can convert to java code dynamically?
What is the pros and cons of using java code to generate the layout?


























The layout XML you are creating is being translated at run-time to java code. So the answer to your question is Yes. You can do the same and basically create all your layout in java code from scratch.


The obvious down grade of this thehnic as you know is that it will take you much more time to achieve the same result as with the XML file.
























But is it all xml layout can convert to java code dynamically?



Yes



What is the pros and cons of using java code to generate the layout?



According to the documentation the advantage to declaring your UI in XML is that it enables you to better separate the presentation of your application from the code that controls its behavior. Your UI descriptions are external to your application code, which means that you can modify or adapt it without having to modify your source code and recompile. For example, you can create XML layouts for different screen orientations, different device screen sizes, and different languages. Additionally, declaring the layout in XML makes it easier to visualize the structure of your UI, so it's easier to debug problems.
