  • Android: Hiding the keyboard in an overrided "Done" keypress of EditText

    - by Marshall Ward
    Hello, I have used a bit of Android code to override the "Done" button in my EditText field: myEditField.setOnEditorActionListener(new TextView.OnEditorActionListener() { @Override public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { if (actionId == EditorInfo.IME_ACTION_DONE) { mySubroutine(); return true; } return false; } }); Activating the field calls up the keyboard, and pressing "Done" evaluates mySubroutine() successfully. However, the keyboard no longer goes away when I press "Done". How do I restore this default behaviour to the routine?

  • Android/Java Beginner: Overriding ArrayAdapter's getView

    - by Preformed Cone
    Firstly I am new to android and Java so this is a beginners question. I have some code that overrides the ArrayAdapter's getView method. Here is the code public View getView(int position, View convertView, ViewGroup parent) { TextView label = (TextView)convertView; if (convertView == null) { convertView = new TextView(ctxt); label = (TextView)convertView; } label.setText(items[position]); return (convertView); } My question is: why does label.setText(items[position]); affect the convertView return value? How are they related / linked?

  • Android - Notification bar height from a service

    - by Vitaliy
    Hi, The application I'm working on is a service which runs in the background in android. The problem is that I need to determine the height of the notification bar for some functionality of the service. I found a number of solutions for this, for regular activities - a view inside an activity can determine its own height without the notification bar, based on checking its actual view size from its onSizeChanged event, after it is already drawn. However, this is not applicable to a service which has no physical view drawn. I would really appreciate any ideas on getting the size of the notification bar at a system level, perhaps? Thanks so much! Vitaliy

  • Android MediaPlayer crashing app

    - by user1555863
    I have an android app with a button that plays a sound. the code for playing the sound: if (mp != null) { mp.release(); } mp = MediaPlayer.create(this, R.raw.match); mp.start(); mp is a field in the activity: public class Game extends Activity implements OnClickListener { /** Called when the activity is first created. */ //variables: MediaPlayer mp; //... The app runs ok, but after clicking the button about 200 times on the emulator, app crashed and gave me this error https://dl.dropbox.com/u/5488790/error.txt (couldn't figure how to post it here so it will appear decently) i am assuming this is because the MediaPlayer object is consuming up too much memory, but isn't mp.release() supposed to take care of this? What am i doing wrong here?

  • How do I take advantage of Android's "Clear Cache" button

    - by Jay Askren
    In Android's settings, in the "Manage Applications" activity when clicking on an app, the data is broken down into Application, Data, and cache. There is also a button to clear the cache. My app caches audio files and I would like the user to be able to clear the cache using this button. How do I store them so they get lumped in with the cache and the user can clear them? I've tried storing files using both of the following techniques: newFile = File.createTempFile("mcb", ".mp3", context.getCacheDir()); newFile = new File(context.getCacheDir(), "mcb.mp3"); newFile.createNewFile(); In both cases, these files are listed as Data and not Cache.

  • Android and config.xml

    - by synic
    Looking in the android sdk folders, I've found a file called values/config.xml. This seems to be somewhere that you can define values for later use in layouts and animations. Given the config.xml: <resources> <string name="config_somePadding">50dip</string> </resources> How would I reference this to use as the layout_height in a layout xml file? @string/config_somePadding is actually the only one I've found that doesn't throw an error in Eclipse (even though there isn't a config_somePadding in values/strings.xml), but it appears to just put an empty string.

  • In Android Browser link does not always execute onClick causing focus instead

    - by Artem
    I am trying to program a very standard JS behavior for a link using an HREF onClick handler, and I am facing a strange problem caused by what I believe to be focus/touch mode behavior on Android. Sometimes when I click on the link, instead of executing the action, it simply becomes selected/focused, with either just a focus rectangle or even also with a filled focus rectangle (selected as opposed to just focused?). The pseudo-code right now is <a href="#" onClick="toggleDivBelowToShowHide(); return false;">go</a> I have tried doing something like: <a href="#" onTouchStart="toggleDivBelowToShowHide(); return false;">go</a> But I still get the same pesky problem some of the time.

  • Best application for process flow with expandable attributes

    - by Marcus
    I am looking for the best software application to do the following I have a set of use cases that are in relationship to each other. I want to show an overview of this relationship. If the user desires the attributes for each use case (such as business rules, data elements, etc) should be expandable. This is potentially a large map which is the reason why the attributes should be expandable / collapsable. Finally all this needs to be printable. Any idea of the ideal application to do this? Thanks a lot in advance

  • Android Class which extends Dialog, how to clear TextViews before it is displayed

    - by wuntee
    I have a class that extends android.app.Dialog, the layout is done in an xml file, and the setup (button listeners, etc) is done on the onCreate method. My problem is that whenever the dialog is displayed, then dismissed, and displayed again, the Editable TextViews are still populated with the information that was displayed previously. What is the common way to clear these text fields? Remember - this is a separate class that extends Dialog - so there is no 'onDialogCreate' like Activity has. Or, perhaps I am extending the wrong class? There is just a lot of processing being done, and do not want to have all the code in the main Activity. I would like it to be in a separate Class. I tried to extend AlertDialog, but it does not create the border like Dialog does. Any help would be great. The dialog is shown via the Activity: protected Dialog onCreateDialog(int id) { switch(id){ case DIALOG_NEW_SAFE: return(new NewSafeDialog(this)); default: return(null); } }

  • Android: Where to find the RadioButton Drawable?

    - by Peterdk
    Ok, I am trying to create a custom view called CheckedRelativeLayout. It's purpose is the same as a CheckedTextView, to be able to use it in a list of items you want selected or in a Spinner. It's all working fine now, I extended RelativeLayout and implemented Checkable interface. However, I am stuck on a quite simple problem: Where can I find the Drawable that CheckedTextView and RadioButton use? I looked at the sourcecode of both, and they seem to use com.android.internal.R. Well... that's internal stuff. So I can't access it. Any way to get these Drawables or solve the problem somehow?

  • Android Image Getter for Larger Images

    - by y ramesh rao
    I have used all the Standard Network related code for Getting Images of about 45KB to 75KB but all are failing these methods work fine for Files of about 3-5KB size of Images. How can I achieve Downloading Image of 45 - 75KB for displaying them on an ImageView in Android for my Netowrk Operations the Things I have used are final URL url = new URL(urlString); final URLConnection conn = url.openConnection(); HttpURLConnection httpConn = (HttpURLConnection) conn; httpConn.setAllowUserInteraction(true); httpConn.setInstanceFollowRedirects(true); httpConn.setRequestMethod("GET"); httpConn.connect(); and the Second option that I have had used is:: DefaultHttpClient httpClient = new DefaultHttpClient(); HttpGet getRequest = new HttpGet(urlString); HttpResponse response = httpClient.execute(getRequest); why is this code functional for Smaller Sized Images and not for Larger Size Images. ?

  • need a web browser in my desktop application

    - by javadahut
    part of the specification of this desktop application is to have a mini browser built in, so that you can enter URL, and navigate the site as you would on a normal browser. Access to the browser page's DOM is required, should let me programmatically change the rendering view of a page, should be cross-platform, renders javascript JDIC seems outdated and I've heard Mozswing doesn't run on Mac.... Jxbrowser license costs a grand and up. Is Java the wrong platform to be creating such app? Are there any other solutions out there for building an application like this ? Thank you.

  • update contact details on Android

    - by frieza
    I would like my code to update contact details (like name, phone number, email, organization details, etc) in the android contact book. I was successful in modifying a few (name, phone number and email to be specific) but not all. Whenever I try to update the organization details (Contacts.Organizations.COMPANY and Contacts.Organizations.TITLE) for a contact my app throws an exception java.lang.UnsupportedOperationException: Cannot update URL: content://contacts/people/69/organizations/69 the code snippet is as follows: Uri baseUri = ContentUris.withAppendedId(People.CONTENT_URI, 69); Uri uri = Uri.withAppendedPath(baseUri, People.Phones.CONTENT_DIRECTORY); Cursor c = this.getContentResolver().query(uri, new String[] { Contacts.Organizations._ID, Contacts.Organizations.COMPANY,Contacts.Organizations.TITLE}, null, null, null); if(c.getCount() > 0) { uri = ContentUris.withAppendedId(uri, c.getString(0)); ContentValues val1 = new ContentValues(); val1.put(Contacts.Organizations.COMPANY, "arw"); val1.put(Contacts.Organizations.TYPE, Contacts.Organizations.TYPE_WORK); val1.put(Contacts.Organizations.TITLE, "abcdef"); this.getContentResolver().insert(uri, val1);

  • How to get debugging statements for Android in Eclipse

    - by Gerry
    I've read the lame documentation, and checked other answers. I'd like my Android app to print some debug statements in the logcat window of Eclispe. If I use the isLoggable method on the various types of debug levels on the Log class, I find that WARN and INFO are returning true. Log.w, and Log.i do not produce any output. Does anyone know which gotchas I've missed? And just to vent, why should this be hard? I've published apps for iphone and bberry and while appreciate the use of java, the platform is reeking of too many "genuiuses" being involved. I suppose Activities and Intents are very flexible, but why? I just want to put up some screens, take some input and show some results. The bberry pushscreen and popscreen is a lot less pretentious. Thanks, Gerry

  • Best way to access database from android

    - by Brandon Delany
    I am working on a Android app and I have a dilemma. I have a list of Objects. I have to update each of these objects with a database. I have 2 methods: Method 1: I can loop through the Objects. For each object I can connect to the server, update it, and then move on to the next Object, and so forth. Method 2: I can store the Objects in a list, send the whole list to the server, update it on the server side, then return a list of updated objects. My questions are: Which method is faster? Which method is easier on the phone's battery? By the way, Method 1 is easier for me to code :). Thank you.

  • difference in logging mechanism: API and application(python)

    - by zubin71
    I am currently writing an API and an application which uses the API. I have gotten suggestions from people stating that I should perform logging using handlers in the application and use a "logger" object for logging from the API. In light of the advice I received above, is the following implementation correct? class test: def __init__(self, verbose): self.logger = logging.getLogger("test") self.logger.setLevel(verbose) def do_something(self): # do something self.logger.log("something") # by doing this i get the error message "No handlers could be found for logger "test" The implementation i had in mind was as follows: #!/usr/bin/python """ .... .... create a logger with a handler .... .... """ myobject = test() try: myobject.do_something() except SomeError: logger.log("cant do something") Id like to get my basics strong, id be grateful for any help and suggestions for code you might recommend I look up. Thnkx!

  • Java (Android) regular expression to strip out HTML paragraph

    - by jackbot
    I have an Android application which grabs some data from an external XML source. I've stripped out some HTML from one of the XML elements, but it's in the format: <p class="x">Some text...</p> <p>Some more text</p> <p>Some final text</p> I want to extract the middle paragraph text, how can I do this? Would a regular expression be the best way? I don't really want to start including external HTML parsing libraries.

  • Integrate IPhone Safari like view in Android?

    - by sunil
    The main concept goes like this. I have four listviews with its own data loaded at the same time. Only one listview will be visible to the user. Now, when the user presses a button, not only the current listview but also other three listviews should be minimized and then user can just scroll just as in Gallery and select the listview that one wants to open. I hope you all have understood what I want. Let me know if someone have some idea of implementing such a User Interface in Android. Thanks & Regards Sunil

  • Android and SQLite using the SQLiteOpenHelper

    - by tunneling
    I have a SQLite database, and several tables within that database. I am developing a DBAdapter for each table within the database. (reference Reto Meier's Professional Android 2 Application Development, Listing 7.1). I am using the adb shell to interface with the database from the command line and see that the database is being populated as I expect. Occasionally, I want to drop a table so that I can ensure it's being built properly, from scratch. The problem is that SQLiteOpenHelper only checks to see if the database exists. Is there a typical solution to writing a helper to also see that the table(s) exists? Basically once I drop a table, the helper checks to see that the database exists and assumes all is well. Also, the CREATE_DATABASE string used in the reference above only creates the one table. Should I consider using the DBAdapter for an adapter to ALL of my tables? That doesn't seem as clean to me.
