Android :: Use SWITCH Statement With SetOnClickListener / OnClick For More Than 1 Button?

Oct 1, 2009

Let's say I have a few buttons in a LinearLayout, 2 of them are:

mycards_button = ((Button)this.findViewById(R.id.Button_MyCards));
exit_button = ((Button)this.findViewById(R.id.Button_Exit));

I register setOnClickListener() on both of them:

mycards_button.setOnClickListener(this);
exit_button.setOnClickListener(this);

How do I make a SWITCH to differentiate between the two buttons within the Onclick ?

Android :: Switch Image Of An ImageButton When User Releases Button?

Feb 7, 2010

I'm trying to make it so that as long as a user is touching the button, it shows one image, and when the user releases the button, it goes back to a default image.

I'm trying to use a selector to make this happen:

CODE:...............

I've tried a few things with the selector, but it always produces the same behavior: the button starts out with the default image, then I press it and it changes to the "record_on" image and it never goes back to the default image when I let go.

Is there a way to get this kind of behavior with an ImageButton, or should I be using something different?

Android :: Using COLLATE In SQLite - Locales Is Ignored In LIKE Statement

Aug 13, 2010

When creating my SQLite database in Android I set the database locale - db.setLocale(new Locale("cz_CZ")). This is a Czech locale. A SELECT statement works and takes the locale into account, for example:

SELECT * from table WHERE name='sctzy' COLLATE LOCALIZED

But using LIKE will fail: SELECT * from table WHERE name LIKE '%sctzy%' COLLATE LOCALIZED

BTW. There is no java.text.Normalized class in Android. I thought I could make a second column with a normalized text, stripped of special characters, which would be used for searching - but I am missing a class or way how to normalize the String.

Android :: Anyone Have A Statement From Google Saying NOT To Use Task Managers?

Aug 1, 2010

Does anyone have a statement released from Google or someone within Google telling the consumers to avoid Task Managers on Android devices.I went into VZW, trying to get an additional battery (usually if u complain they send u an additional battery) because I'm getting 5-7 hours out of my battery even when I'm careful and try to stretch my battery. So the women asked questions, do u use Wifi...NEVER, don't even turn it on. Brightness? It's 1/8th of the way on to full brightness, Task manager?No Google said not to use one..So she wouldn't send me a battery because she said that its because I don't use a task manager.I was telling her Google had advised us not to and she said, that's false that Google has approved them to put task managers on people's phones who are having battery problems.(I don't believe that)I looked around Google and could only find it from joe-shomes but couldn't find a statement from Google. Can anyone provide a statement from Google that advises us not to use task managers?

Android :: Sqlite - Big Tables And Like/glob Statement

Apr 25, 2009

Anyone working with big sqlite tables and trying to match rows using patterns (for example for autocomplete purposes) ? recently i played with LIKE statement and it seems it will never use table index (if any), you have to use GLOB instead. but....... the weird thing is that you cannot use selectionParams in your query: you have to specify your pattern in selection like:

CODE:........

My words table has two TEXT columns: 'key' and 'value' and index on 'key'

For example: i have table with ~28000 rows and when using selectionParams my query took 1500 ms and without selectionParams 20 ms does it have anything to do with android or its sqlite weird feature?

Android :: Make Java Assert Statement Work?

How do I make the Java assert statement work? By "work" I mean that a failed assertion should either stop program execution or at least log the failure. Currently, neither happens. I understand there is a run- time option to enable this (-ea), but I don't know where to specify it. Changing "PreferencesJavaInstalled JREsEdit JREDefault VM Arguments" has no effect, probably because those settings are not used for the Android execution.

Android :: Include Library Based On API Level Or If Statement?

Aug 17, 2010

So I have a API issue. So i am creating a class that utilizes AndroidHttpClient to download Bitmap images from my server. Problem is, it's API Level is 8 and I want this to be used FROM API 1 and above, now i know i can use DefaultHttpClient (the API is Level 1) but is there a way i can use both, being distinguished by Build.VERSION.SDK (btw thanx for the quick respose, Konstantin Burov and iandisme). So for example, if my device is 2.2 i use AndroidHttpClient, anything else use DefaultHttpClient. Of Course if I import the library it will give me an error on any device 1.5 to 2.1. Any Suggestions would greatly be appreciated, because in the future I would want to set other preferences based on API.

Android :: Is SQLiteStatement - Prepared Statement - Thread-safe?

Sep 20, 2010

I'm wondering whether prepared statements in Android (instances of SQLiteStatement) are thread-safe. In particular I'm asking with regard to the following scenario:

In a ContentProvider you create a pre-compiled insert statement during onCreate. Then, in the overriden insert method you make use of this statement by binding a set of parameters to it and calling executeInsert on it.

We know that a ContentProvider has to be written in a thread-safe manner. If SQLiteStatement does not bind parameters per thread, a concurrent call to the provider's insert method would alter the statement's bindings and result in unpredictable behavior.

Android's own Contacts provider uses prepared statements in this way (http://bit.ly/bDuKAT), so I tend to believe that they are in fact thread-safe. Looking at the source code of SQLiteStatement I don't see how though (http://bit.ly/9M1Swv).

So, is SQLiteStatement (or SQLiteProgram that is) thread-safe with respect to parameter binding or not?

Android :: SQLite Statement Produce Result To Indicate Duplicate Entries?

Oct 28, 2009

For my application, I am trying to add entries without having a duplicate entry, and if there are a duplicate notify the user and have him try again. Using SQLite, which I know very very little about, I have tried these two ways and want to know which one is better, more efficient or a better way to develop it? First way:

db.execSQL("INSERT INTO " + DatabaseHelper.DATABASE_TABLE +
"(LATITUDE, LONGITUDE, RATING) SELECT " + latitude + ", " + longitude + ", " + rating +
" WHERE NOT EXISTS (SELECT 1 FROM " + DatabaseHelper.DATABASE_TABLE +
" WHERE LATITUDE = " + latitude + " AND LONGITUDE = " + longitude + ")");

Second way:

long id = -1;
try { id = db.compileStatement(
"SELECT COUNT(*) FROM " + DatabaseHelper.DATABASE_TABLE
+ " WHERE LATITUDE = " + latitude
+ " AND LONGITUDE = " + longitude)
.simpleQueryForLong();
} catch (NullPointerException e) { return -1;
} return id;

The first way, either inserts or ignores the values, I check by doing so, storing the row-count of the rows into a variable before the call, call that function, and then check its results. If the results is not higher than it was before the call, the insert was made ignored, prompt the user with the 'values exist' message. (Very sloppy, I know but desperate times calls for desperate measures). The second way, returns the actual count of rows that match the numbers I want to store, if the number returned greater than 1, prompt the user with the 'values exist' message. I have been going back and forth, trying different ways but I do not know how to set up SQLite to have UNIQUE pairs, which I was told would be the easiest.
