I want to create multiple handlers that gets triggered based on users selection, but this handlers implement the same runnable method. the only difference is that they call different postDelayed() method. how do i go about achieving this without rewriting the same code for the runnable? i am still not clear about how the handleMessages() works and if it can be used for this?

View 2 Replies View RelatedWhich is the way to attach the custom event handlers for the activities, in case they support one, when the activity is started using Intent and startActivity() methods.

View 2 Replies View RelatedI've more than one Handlers in an Activity. I create all the handlers in the onCreate() of the main activity. My understanding is the handleMessage() method of each handler will never be called at the same time because all messages are put in the same queue (the Activity thread MessageQueue). Therefore, they will be executed in the order in which are put into the Queue. They will also be executed in the main activity thread. Is this correct ? Code...

This question is related to an existing question I asked. I though I'll ask a new question instead of replying back to the other question. Cannot "comment" on my previous question because of a word limit. Marc wrote - I've more than one Handlers in an Activity." Why? If you do not want a complicated handleMessage() method, then use post() (on Handler or View) to break the logic up into individual Runnable. Multiple Handlers makes me nervous. I'm new to Android. Is having multiple handlers in a single activity a bad design ?
I'm new to Android.My question is - is having multiple handlers in a single activity a bad design ? Here is the sketch of my current implementation. I've a mapActivity that creates a data thread (a UDP socket that listens for data).
My first handler is responsible for sending data from the data thread to the activity. On the map I've a bunch of "dynamic" markers that are refreshed frequently. Some of these markers are video markers i.e., if the user clicks a video marker, I add a ViewView that extends a android.opengl.GLSurfaceView to my map activity and display video on this new vide.
I use my second handler to send information about the marker that the user tapped on ItemizedOverlay onTap(int index) method.The user can close the video view by tapping on the video view. I use my third handler for this. I would appreciate if people can tell me what's wrong with this approach and suggest better ways to implement this.
I am writing an Application that has multiple layouts with buttons. I have set up onClickListners for the buttons. Some buttons will change the activity and bring up a new layout with new buttons, and others will send outgoing SPP strings over Bluetooth. The strings will be defined in an XML file and will not change (serial commands).I can hard code the MAC address of the Bluetooth Server and only need to send data, not receive.
I am looking for some general guidance on the direction to go as far as setting up my Bluetooth connection and outgoing transmissions. I have looked at the BluetoothChat example extensively but do not have any good resources in the case of multiple activities.
-Do I use a separate activity to manage all Bluetooth transmissions and connections and create handlers for every case where I would send a Bluetooth message?
-Should I add Bluetooth connection+transmission threads in every activity (seems like i would run into issues losing the connection when changing activities)?
-Can I use handlers that are not class specific where the BluetoothService Activity could send whatever was prompted by the active/current activity?
-Could I just hard code all strings to be sent in the BluetoothService Activity and the UI activity could prompt the BluetoothService Activity to send the requested string based on the button click?
I was very confused when I looked at the list of my contacts the first ftime after syncing them to the Desire. Only then I realized: this thing is sorting first names first! I find this most annoying and unusual. And worse: I found no setting, yet, that would allow me to choose the sorting.

I'm writing a microblog client for Android to go along with my Windows client (MahTweets). At the moment I've got Tweets coming and going without fail, the problem is with the UI.

It's even worse as you have paid and free apps mixed together.

I'm looking for a detailed App for sorting and categorizing all of my contacts. I have 700 phone numbers, and am a junior in college, so needless to say, sometimes it's nice to only see female phone numbers. Also, if there is one where you could sort people by key words like soccer, school, parties, etc. Also, with the Verizon network, is there anyway to send texts to more than ten people at once? Is there anything like that out there available for my droid? Is there a way to sort/edit my contacts on my computer? I feel like it would be much easier.

I've updated (uploaded a new version) of my app, TimeTracker, twice in the past couple of months, and in both cases, the new upload has not shown up in the "by date" sorted list of the Market app. When I search for the app, I see the correct version in the Market, and I can find it in the correct category by scrolling down; it is just that the updates aren't being correctly sorted.
View 12 Replies View RelatedOne of the task of we are working on is to enable the Android Contact sorting by stroke for LOCALE zh_TW. It's very easy to enable the contact sorting by Pinyin for zh_CN, but when I take the same method to enable sorting stroke for zh_TW, the sorting result is either sorted by UNICODDE or PinYin. It's very strange. I have investigated the related code located in android_pkgs/external/icu4c/xxx and tried many options but failed to find a wayout. Is there anybody familiar with icu4c or have ever done some work on this topic? Here I'd like to append the steps (mainly on the location android_pkgs/external/icu4c/) I did as reference:
a. append zh_TW into product locales;
b. append the zh_TW support into icu4c/stubdata/Android.mk
c. taking the cfg-us as example, create a folder cfg-us-zh and append zh_xx related 'zh_xxx.res' files;
d. ./helper.sh us-zh will generate a updated icudt38l-us-zh.dat;
e. recompile Android to launch emulator -EOM-
I implement ProviderTestCase2 to test my content provider functions. And when I insert huge number (about 10000) of data, the insert, delete and update functions are fine. But the query function will have SQLiteDiskIOOException: disk I/O error. And the data number limit of causing the exception is about 5000. Is it bug of content provider?
And there is another problem. Each of my data has different priority. When I sort my data by priority, its no problem. But when I change priority of some data and then sorting again. Sometimes I will get incorrect result and I'm sure its not logical problem of test program.
Is it possible to actually re-sort an Android SQL DB? for example, I want to resort the Bookmarks DB. I can query the data and sort it with "Browser.BookmarkColumns.TITLE + " ASC" in the query but this will only sort the list shown to the user and will not sort the DB itself. Therefore, if a user uses my app to sort the Bookmarks by Title(ASC) and then goes to the Android Browser Bookmarks - the order will remain default (other than the one selected on my app).
View 11 Replies View RelatedI've run into an issue with an autocomplete field I'm working on.The field I'm working with is composed of the form "<NAME> (<CODE>)".When a user starts typing in text, I want to display any results that match either NAME or CODE.For example, if this list contains items and their codes, like "Personal Computer (PC)", then I'd want the list to pop up that row if the user types "P", "PC", "Per", etc.However, the problem I'm running into now is how to best sort the results that come back from this.For example, If someone enters "PC", I want "Personal Computer (PC)" to be the first result. However, if there's another row (you'll have to bear with me as this is contrived) "PC Case (301)", then there's no simple ordering I can do on the results to ensure that the best match appears first. Ordering by name and code both returns PC Case first.I want a query where it returns the best match first, rather than items in alphabetical order.Is there such a function I can use in SQLite to get this, or should I return the results and then mess with the order in the code?
