  • Android Progress Dialog not showing

    - by ilomambo
    This is the handler, in the main Thread, which shows and dismisses a progress dialog. public static final int SHOW = 0; public static final int DISMISS = 1; public Handler pdHandler = new Handler() { @Override public void handleMessage(Message msg) { Log.i(TAG, "+ handleMessage(msg:" + msg + ")"); switch(msg.what) { case SHOW: pd = ProgressDialog.show(LogViewer.this, "", getText(R.string.loading_msg), true); break; case DISMISS: if(pd != null) { pd.dismiss(); pd = null; } break; } } }; The message to show the progress is: pdHandler.sendMessage(pdHandler.obtainMessage(SHOW)); The message to dismiss it is: pdHandler.sendMessage(pdHandler.obtainMessage(DISMISS)); It works well when I call it before I start an AsyncTask, the AsyncTask onPostExecute() dismisses it. But when it runs within a runnable (runOnUiThread), the dialog does not show. Examining the pd variable on the debugger, it shows that is is created, it is running and it is visible, but in practice it is not visible. Any suggestion? UPDATE: I did the obvious test I should have done in the first place. I commented the DISMISS message. And the progress dialog did show up. It appeared too late, after the runnable was finished. I undestand now that the DISMISS message did dismiss the not-yet-visible ProgressDialog, that's why I did not see it. The question becomes now: I need the ProgressDialog to show BEFORE the runnable code is executed. And it is not so straight forward. My call hierarchy is like this: onScrollEventChanged --> runOnUiThread ( --> checkScrollLimits --> if need to scroll show ProgressDialog "Loading" get new data into table dismiss ProgressDIalog ) I tried something like this: onScrollEventChanged --> checkScrollLimits --> if need to scroll show ProgressDialog "Loading" --> runOnUiThread ( get new data into table dismiss ProgressDIalog ) But still the dismiss message got there before the ProgressDialog could show. According to Logcat there is a five second interval between the arrival of the SHOW message and the arrival of the DISMISS message. UPDATE II: I though I will use the isShowing() method of ProgressDIalog pd = ProgressDialog.show(...) while(!pd.isShowing()); But it does not help at all, it returns true even if the dialog is not showing yet.

  • Android string formatiing from xml

    - by mann
    I am parsing xml from server. One of its node contains data like <distance>16.3432434324354324km</distance> I am putting it into hashmap like for (int i = 0; i < nl.getLength(); i++) { map.put(KEY_DISTANCE, parser.getValue(e, KEY_DISTANCE)); // adding HashList to ArrayList menuItems.add(map); } Everything is nice. But i want it two decimal places for example i want its value should be 16.34km rather then 16.343234324342342km I tried with DecimalFormat twoDForm=new DecimalFormat("##.00"); try{ Double StartVTwo=Double.valueOf(KEY_DISTANCE); Double resultDouble1 = Double.valueOf(twoDForm.format(StartVTwo)); Log.e("check", String.valueOf(resultDouble1)); }catch (NumberFormatException e){ Log.e("error"," This is error "); } But it shows exception and prints this message. Any help would be appreciated!!

  • Responding to preference updates in Android

    - by hgpc
    I am calling a PreferenceActivity from another activity and then updating the application state (ie: changing the font size) on onActivityResult, based on the preference changes. I was thinking it would be better to put the state update logic in the PreferenceActivity. That way I don't have the duplicate the logic in each activity that calls the PreferenceActivity. What's the best or correct way to do this?

  • CursorLoader, get URI for local database

    - by user1681358
    I'm a newbie android programmer and I recently followed a tutorial which shows how to create a local SQLite database by using SQLiteDatabase.rawQuery to return a Cursor. I would like to modify my app to use CursorLoader which is apparently a better way to access the database. My problem is the CursorLoader constructor expects a URI to be given. Do I just input "file:///[path to db]"? Seems a bit messy.

  • How to view my Android app created database, via my android app?

    - by suufang
    I'm creating an application that collects users location (Cell broadcast location code) and saves that location with a name of users option, for example say my CB location code is 546034, now my app allows me to store that location code with a name of my choice say 'Home'. So, essentially my app has that following modules, To collect users CB location. To collect a custom name from user of that location. To store these values in a database. I've succeeded in doing all the above modules. I have a sub-module for my third module which has an option for user, of showing and deleting the database values, the screen shot looks as follows, Now, Users should be able to view and delete entries when he chooses the option 'View my database of locations' I've learned how to query my database values and I'm stuck with creating a list view and providing the delete option. My code for getting the database values and querying values goes as follows, submit.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { String locname = name.getText().toString(); if(locname.length()==0) { Toast.makeText(getBaseContext(), "Please enter the location name, for example 'Home'.", Toast.LENGTH_LONG).show(); } else { SQLiteDatabase cd = openOrCreateDatabase("mydata", MODE_WORLD_READABLE, null); cd.execSQL("CREATE TABLE IF NOT EXISTS MLITable (CblocationCode INT(10), CblocationName VARCHAR);"); cd.execSQL("INSERT INTO MLITable VALUES ('"+str+ "','"+locname+ "');"); cd.close(); Toast.makeText(getBaseContext(), "value successfully entered.", Toast.LENGTH_LONG).show(); } } }); viewdb.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { // here comes the code for viewing the database and deleting SQLiteDatabase db = openOrCreateDatabase("mydata", MODE_WORLD_READABLE, null); Cursor c = db.rawQuery("SELECT * FROM MLITble", null); db.close(); } }); I can see that I've read the table values, but I'm not able to create a display for those values. Help required. Thank you.

  • Java/Android get array from xml

    - by Ashley
    I have a list of longitude and longitude points in an xml file that is used throughout my application. I find my self repeating this code to get points often and think there must be a better way? String[] mTempArray = getResources().getStringArray(R.array.stations); int len = mTempArray.length; mStationArray = new ArrayList<Station>(); for(int i = 0; i < len; i++){ Station s = new Station(); String[] fields = mTempArray[i].split("[\t ]"); s.setValuesFromArray(fields); Log.i("ADD STATION", ""+s); mStationArray.add(s); } XML is in the format of: <?xml version="1.0" encoding="utf-8"?> <resources> <array name="stations"> <item> <name>Station name</name> <longitude>1111111</longitude> <latitude>11111</latitude> <code>1</code> </item> And another (possible) problem is that to get just one station I have to get all of them and pull the one I want from the array. Is this going to be considerably slower? Can I make this array consistent throughout the app? (But keeping the separate Intent methodology)

  • Creating android app Database with big amount of data

    - by Thomas
    Hi all, The database of my application need to be filled with a lot of data, so during onCreate(), it's not only some create table sql instructions, there is a lot of inserts. The solution I chose is to store all this instructions in a sql file located in res/raw and which is loaded with Resources.openRawResource(id). It works well but I face to encoding issue, I have some accentuated caharacters in the sql file which appears bad in my application. This my code to do this : public String getFileContent(Resources resources, int rawId) throws IOException { InputStream is = resources.openRawResource(rawId); int size = is.available(); // Read the entire asset into a local byte buffer. byte[] buffer = new byte[size]; is.read(buffer); is.close(); // Convert the buffer into a string. return new String(buffer); } public void onCreate(SQLiteDatabase db) { try { // get file content String sqlCode = getFileContent(mCtx.getResources(), R.raw.db_create); // execute code for (String sqlStatements : sqlCode.split(";")) { db.execSQL(sqlStatements); } Log.v("Creating database done."); } catch (IOException e) { // Should never happen! Log.e("Error reading sql file " + e.getMessage(), e); throw new RuntimeException(e); } catch (SQLException e) { Log.e("Error executing sql code " + e.getMessage(), e); throw new RuntimeException(e); } The solution I found to avoid this is to load the sql instructions from a huge static final string instead of a file, and all accentutated characters appears well. But Isn't there a more elegant way to load sql instructions than a big static final String attribute with all sql instructions ? Thanks in advance Thomas

  • Download and replace Android resource files

    - by Casebash
    My application will have some customisation for each company that uses it. Up until now, I have been loading images and strings from resource files. The idea is that the default resources will be distributed with the application and company specific resources will be loaded from our server after they click on a link from an email to launch the initialisation intent. Does anyone know how to replace resource files? I would really like to keep using resource files to avoid rewriting a lot of code/XML. I would distribute the application from our own server, rather than through the app store, so that we could have one version per company, but unfortunately this will give quite nasty security warnings that would concern our customers.

  • Handling multiple accounts in Android app

    - by bebeTech
    I would like to build an application that caters for multiple accounts (eg. home, work) and account types (e.g. ISP, VoIP, Mobile). Essentially, I would like to get the user to create the accounts they want and then have all the accounts listed on the start page grouped by type. For example: ISP: - Home - Work Mobile: - Mum - Dad When you click on the account, it would take you to another screen where I do a bunch of calcs and display the results. I currently do this via multiple apps but am looking at consolidating into the one app. I am just not sure where to start or how I go about achieving this? The way the Contacts app works is a good example of what I am wanting to do.

  • Private API and SMS content URI's on Android

    - by Shadow
    Without accessing private API's to get Content URI's, etc. for SMS, how are we expected to query this data? I am currently in the process of writing my own SMS app and I want to stay as compatible as possible. Without storing the information myself in my own database (such that I can store the text messages so that other programs can access the data when/if they delete my app) and without using private API's how the heck are we suppose to query SMS data?

  • Closing several android activities simultaneously

    - by teedyay
    In my application you can navigate through several Activities until the Activity stack is quite deep. We'd like a button on every Activity that will take you straight back to the main menu - i.e. pop all Activities from the stack except the first one. I've put the button in a View that I can easily put on every Activity in the application, but I can't figure out how to close several Activities in one fell swoop. (If possible, it would be good if the View could work out how many Activities to close by itself - i.e. detect how deep on the stack its own Activity is.)
