I'm trying to structure a URI that accesses my data by id. Currently my URIs are query based like so: How could I structure a similar URI so that I could query for notes in multiple lists?

I've got a database. In its "tags" column, rows can have a combination of multiple values "A, B, C"--such that: row 1 has "A" row 2 has "A, C" row 3 has "B, A" and so on, in various permutations. I am trying to implement search using a managedQuery such that I can return a cursor that contains rows with one or more values in the query. For example, if the user enters "C, A" for a search, s/he should get all rows that have A, C, or A and C. I'm splitting the user query on the comma (",") character, and the final call is as follows (parameters replaced by actual values):
mActivity.managedQuery("content_uri", [id, title, tags], "title LIKE ? OR tags LIKE ?", [%A% OR %C%, %A% OR %C%], "title ASC")
Even though there are rows in the database that contain A, C, or A and C--the managedQuery returns nothing. Thankfully, if the query is for "A", or for "C", the appropriate rows with "A" or "C" or "A and C" are returned. It's just that a query with more than one search term returns nothing. What am I doing wrong here? My guess is that %A% OR %C% is incorrect logic, but why?
I am new to developing for android. I have a question regarding some best practices. My app is like a dashboard from which multiple different "sub-activities" can be started and done. I am wondering what is the best way to structure the app. One way is to have different layouts and load and unload them appropriately. The other is to start new activities using intents. At least this is what I have gathered from what I have read.
View 3 Replies View RelatedMy Android app has a ContactsList activity in which I simply display a list of contacts that are on the phone. Only recently I noticed that my activity only displays contacts synced with my main Google account. I have two Google accounts on my test phone and ideally I want my activity to display the contacts for both accounts (or multiple accounts). How do I query across multiple accounts?
View 2 Replies View RelatedI have the following code which queries 1 number of a contact. It works. But how can I change it so that I can query multiple numbers (work, mobile, home) for the same contact and the type of each number?int phoneColumnIndex = cursor.getColumnIndex(People.NUMBER); if (phoneColumnIndex != -1) {String phone Number = cursor.getString (phone ColumnIndex); System.out.println (" phoneNumber:" + phoneNumber);
View 2 Replies View RelatedI am setting multiple alarms like this, with different values of id. Multiple calls to AlarmManager.setRepeating deliver the same Intent/PendingIntent extra values, but I supplied different ones.
AlarmManager alarms = (AlarmManager)context.getSystemService(
Context.ALARM_SERVICE); Intent i = new Intent(MyReceiver.ACTION_ALARM);
// "com.example.ALARM" i.putExtra(MyReceiver.EXTRA_ID, id);
// "com.example.ID", 2 PendingIntent p = PendingIntent.getBroadcast(context, 0, i, 0);
alarms.setRepeating(AlarmManager.RTC_WAKEUP, nextMillis, 300000, p); // 5 mins
And receiving them like this:
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_ALARM)) {
// It's time to sound/show an alarm
final long id = intent.getLongExtra(EXTRA_ID, -1);
The alarm is delivered to my receiver at the right times, but often with EXTRA_ID set to the wrong value: it's a value that I have used at some point, just not the one that I wanted delivered at that particular time.
I've got a query, (I'm using rawQuery())
SELECT * FROM <table>
I'm then storing what it returns using a cursor. From their what I want to do is, start at the first row so.. cursor.moveToFirst() then take each column , column by column and store its particular value in a variable. I then want to move onto the next row and do the same. So I guess my question is How would I get cursor to deal with multiple columns?
Is it possible to store strings values in multiple files? Eg, strings.xml, strings1.xml, strings2.xml etc.
I do not mean localized versions of the same file - those multiple files should contain different string ids in the same language, so in code they would be refered like: R.strings1.my_string_1 R.strings1.my_string_2 R.strings2.my_string_3 etc. So, "strings1", "strings2", "strings3" would be a kind of namespace for them.
Or, another way is to have multiple R classes inside one project, which would deal with different stringsXXX.xml files.
Like, currently we can refer to "my.name.space.R" and to "android.R" at the same time, so is it possible to have: android.R my.name.space1.R my.name.space2.R etc
At the same time inside single project?
Edit: Okay, I found a solution. Don't know that it's the proper solution, but it does work correctly. Added to the code below. I'm trying to allow a user to select a number of directories from a checklist, and return them upon clicking a "Submit" button. Here's a snippet of my code. It populates the List View with all the directories on /sd card/, and for the initial selection (of however many I pick) when I submit, the log shows the correct choices returned. However, if I un check an item, and click "Submit" again, it still shows as if all are selected. Do I need to write a handler to un check an item? I thought that was taken care of by the choice Mode selection?
View 1 Replies View RelatedI have the following code to intantiate a SimpleCursorAdapter to use with a ListView. As you can see I have passed the R.layout.log_item to display the list items, and one value/control to bind to (TripDate).
SimpleCursorAdapter sca = new SimpleCursorAdapter(this, R.layout.log_item,c,new String[] {DBAdapter.KEY_LOG_TRIPDATE},new int[]{R.id.txtTripDate});
This works. I currently only have one widget in the layout xml, a TextView to hold the TripDate.
How do I pass multiple binding parameters for the additional widgets in the layout? So I can also display other info.
I'm writing an RSS reader for Android. I've faced a certain difficulty which the problem I can't resolve since databases aren't my expertise.. So i figured out maybe one of you could help me out! I currently have 3 tables (Categories, links and feeds). My goal is too link a feed to multiple categories. Therefor I'm using a Link table. My databases is an Android ContentProvider (sqlite) and looks like the following:
| Categories | | Links | | Feeds |
|------------| |---------| |-------|
| _ID | | Category| | _ID |
| Title | | Feed | | Title |
| URL |
I currently wrote the following code in my FeedListActivity to retrieve a list of links and their feeds.
CODE:.................
Now my question:
I was wondering how I could optimize this database layout, code or query so I would get my entries in a more efficient way. Because i believe this link table or the query to retrieve links isn't needed! Or am i doing this the correct way?

View 4 Replies View RelatedI'm trying to create a simple Workout Timer for Android. The user creates a WorkoutPlan containing info such as total duration, total rest time, etc, the app will display a timer that updates every second.
Pretty simple to begin with, but I'm trying to build the app as properly as possible, i.e. separation of concern, correct techniques, responsive UI, ensure the timer will be accurate, etc.
Here's a simplification of what I have so far:
WorkoutPlan, the user can load/save different workout plans to the timer
Code:
public class WorkoutPlan {
public long duration;
}
TimerThread, this class implements `Runnable`, it takes in a `WorkoutPlan` in the constructor, start/stop, shows elapsed time.
Code:
public class TimerThread implements Runnable {
public boolean running = false;
[Code]....
TimerView, the custom view that displays the elapsed time
Code:
public class TimerView extends View {
private final Paint mBg;
private final Paint mText;
private WorkoutPlan plan;
private TimerThread timer;
private Thread thread;
private Handler handler = new TimerHandler();
[Code]...
Finally, WorkoutTimer, the activity that starts it off
Code:
public class WorkoutTimer extends Activity {
private TimerView mTimer;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
[Code]....
A couple of questions:
Where's the best place to create the `WorkoutPlan` object? Currently it's done in `TimerView`. Should it be done in the `WorkoutTimer` activity instead? If yes, how do I pass the `WorkoutPlan` object to `TimerView`?
The app works fine the first time, but crashes when I go to the home screen then back to the app the second time. What's causing it to crash? Is it the theading?
Currently I'm using a `Handler` in a new `Thread`. Is this ok or would a `TimerTask` be better? Where's the best place to start the thread? Am I correct to put all the threading code in `TimerView`?
Am I correct to add synchronized to all the methods in `TimerThread`?

I fear the answer is no, but before I change the structure of all of my log messages: Is there any way to do this: $ adb logcat *:S com.myappname.*:V
Or in words: I want to silence every tag that goes to logcat except the ones that begin with com.myappname. Currently my classes print into the log with this.getClass().getName() as the tag - typing each tag out individually in the filter isn't an option, so is there anyway to use the wildcard? The above command doesn't work, because it just silences every class, including the ones I've explicitly told to be verbal. I've also tried:
$ adb logcat -s com.myappname.*:V $ adb logcat com.myappname.*:V *:S
to no avail. I have a feeling I might have to log in a more constant fashion. Or I might just use log4J.

View 1 Replies View RelatedI recently started programming in Android, and as a beginning project I am trying to build a logo quiz app. The idea: You see a splash screen after opening the app (play game - about). Play game takes you to a new activity called LevelSelector.java where you can choose the level you want to play. Clicking on a level takes you to another new Activity Level.java.I created a SQLite db with 20 questions in it which I install with a DBHelper.java class, every question also has a level column.
However, I get lost in my global structure. Since I work with different levels I don't want to make a new class for every level. I guess I lost the overview due to my lack of programming in android, but I figured the best way to learn it is (after I watched tutorials) to build an app myself..
