  • Android - TimePicker selecting the button and input field

    - by teepusink
    Hi, I'm trying to modified the way TimePicker works as asked in my question here http://stackoverflow.com/questions/2580216/android-timepicker-minutes-to-15 To be able to do that I need to know if the + and - button was clicked and to disable the input field. So can I target the elements in a TimePicker? (i.e the + and - button and the input field)? Also is there anyway to determine if the + or the - button was clicked? Thanks, Tee

  • Android List with section headers

    - by user324661
    Hi, I'm trying to create a list with headers above a grouping of items. I was looking at SeperatedListAdapter available here: http://jsharkey.org/blog/2008/08/18/separating-lists-with-headers-in-android-09/ but I ran into an error (ERROR/AndroidRuntime(2025): java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView ) Now I'm looking into more options including making a new one. Do you guys have any hints? Thanks, Bryon

  • Android::Webview removes scrollbar for a DIV

    - by Legend
    I made a small webpage with a scrollable div. When I load it in a browser, it works fine. But when I load it in a webview inside Android, it doesn't let me scroll the div. Is there a workaround for this or do I have to use a different design? I am talking about websites like this.

  • Android: RTL support - digits embedded in a right to left sentence (Hebrew)

    - by Rob
    Hi There, My application displays Hebrew text which comes from a Web Service. When a sentence contains digits (in the middle of it), the digits appear in a mirror view: 29 appears as 92, 21:45 appears as 54:12 and 2,000 appears as 000,2. Also, when a sentence starts with digits or English characters, they get thrown to the end of the sentence messing it all up... Does anyone have an idea how can this be solved? Is RTL support in Android still immature? Thanks, Rob

  • Android AnimationDrawable and knowing when animation ends

    - by LostDroid
    I want to do an animation with several image-files, and for this the AnimationDrawable works very well. However, I need to know when the animation starts and when it ends (i.e add a listener like the Animation.AnimationListener). After having searched for answers, I'm having a bad feeling the AnimationDrawable does not support listeners.. Does anyone know how to do frame-by-frame image animation on Android?

  • Android: database reading problem throws exception

    - by Vamsi
    Hi, i am having this problem with the android database. I adopted the DBAdapter file the NotepadAdv3 example from the google android page. DBAdapter.java public class DBAdapter { private static final String TAG = "DBAdapter"; private static final String DATABASE_NAME = "PasswordDb"; private static final String DATABASE_TABLE = "myuserdata"; private static final String DATABASE_USERKEY = "myuserkey"; private static final int DATABASE_VERSION = 2; public static final String KEY_USERKEY = "userkey"; public static final String KEY_TITLE = "title"; public static final String KEY_DATA = "data"; public static final String KEY_ROWID = "_id"; private final Context mContext; private DatabaseHelper mDbHelper; private SQLiteDatabase mDb; private static final String DB_CREATE_KEY = "create table " + DATABASE_USERKEY + " (" + "userkey text not null" +");"; private static final String DB_CREATE_DATA = "create table " + DATABASE_TABLE + " (" + "_id integer primary key autoincrement, " + "title text not null" + "data text" +");"; private static class DatabaseHelper extends SQLiteOpenHelper { DatabaseHelper(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL(DB_CREATE_KEY); db.execSQL(DB_CREATE_DATA); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { Log.w(TAG, "Upgrading database from version " + oldVersion + " to " + newVersion + ", which will destroy all old data"); db.execSQL("DROP TABLE IF EXISTS myuserkey"); db.execSQL("DROP TABLE IF EXISTS myuserdata"); onCreate(db); } } public DBAdapter(Context ctx) { this.mContext = ctx; } public DBAdapter Open() throws SQLException{ try { mDbHelper = new DatabaseHelper(mContext); } catch(Exception e){ Log.e(TAG, e.toString()); } mDb = mDbHelper.getWritableDatabase(); return this; } public void close(){ mDbHelper.close(); } public Long storeKey(String userKey){ ContentValues initialValues = new ContentValues(); initialValues.put(KEY_USERKEY, userKey); try { mDb.delete(DATABASE_USERKEY, "1=1", null); } catch(Exception e) { Log.e(TAG, e.toString()); } return mDb.insert(DATABASE_USERKEY, null, initialValues); } public String retrieveKey() { final Cursor c; try { c = mDb.query(DATABASE_USERKEY, new String[] { KEY_USERKEY}, null, null, null, null, null); }catch(Exception e){ Log.e(TAG, e.toString()); return ""; } if(c.moveToFirst()){ return c.getString(0); } else{ Log.d(TAG, "UserKey Empty"); } return ""; } //not including any function related to "myuserdata" table } Class1.java { mUserKey = mDbHelper.retrieveKey(); mDbHelper.storeKey(Key); } the error that i am receiving is from Log.e(TAG, e.toString()) in the methods retrieveKey() and storeKey() "no such table: myuserkey: , while compiling: SELECT userkey FROM myuserkey"

  • JSON Post To Rails From Android

    - by Stealthnh
    I'm currently working on an android app that interfaces with a Ruby on Rails app through XML and JSON. I can currently pull all my posts from my website through XML but I can't seem to post via JSON. My app currently builds a JSON object from a form that looks a little something like this: { "post": { "other_param": "1", "post_content": "Blah blah blah" } } On my server I believe the Create method in my Posts Controller is set up correctly: def create @post = current_user.posts.build(params[:post]) respond_to do |format| if @post.save format.html { redirect_to @post, notice: 'Post was successfully created.' } format.json { render json: @post, status: :created, location: @post } format.xml { render xml: @post, status: :created, location: @post } else format.html { render action: "new" } format.json { render json: @post.errors, status: :unprocessable_entity } format.xml { render xml: @post.errors, status: :unprocessable_entity } end end end And in my android app I have a method that takes that JSON Object I posted earlier as a parameter along with the username and password for being authenticated (Authentication is working I've tested it, and yes Simple HTTP authentication is probably not the best choice but its a quick and dirty fix) and it then sends the JSON Object through HTTP POST to the rails server. This is that method: public static void sendPost(JSONObject post, String email, String password) { DefaultHttpClient client = new DefaultHttpClient(); client.getCredentialsProvider().setCredentials(new AuthScope(null,-1), new UsernamePasswordCredentials(email,password)); HttpPost httpPost = new HttpPost("http://mysite.com/posts"); JSONObject holder = new JSONObject(); try { holder.put("post", post); StringEntity se = new StringEntity(holder.toString()); Log.d("SendPostHTTP", holder.toString()); httpPost.setEntity(se); httpPost.setHeader("Content-Type","application/json"); } catch (UnsupportedEncodingException e) { Log.e("Error",""+e); e.printStackTrace(); } catch (JSONException js) { js.printStackTrace(); } HttpResponse response = null; try { response = client.execute(httpPost); } catch (ClientProtocolException e) { e.printStackTrace(); Log.e("ClientProtocol",""+e); } catch (IOException e) { e.printStackTrace(); Log.e("IO",""+e); } HttpEntity entity = response.getEntity(); if (entity != null) { try { entity.consumeContent(); } catch (IOException e) { Log.e("IO E",""+e); e.printStackTrace(); } } } Currently when I call this method and pass it the correct JSON Object it doesn't do anything and I have no clue why or how to figure out what is going wrong. Is my JSON still formatted wrong, does there really need to be that holder around the other data? Or do I need to use something other than HTTP POST? Or is this just something on the Rails end? A route or controller that isn't right? I'd be really grateful if someone could point me in the right direction, because I don't know where to go from here.

  • does android 1.5 saves fpu regs on context switch

    - by fazo
    i'm asking 1.5 and up or is it dependant on what's in ".config" when compiled for my phone? (and yes, i know that android has to support processors with soft-float, but several libm on different phones do have hard-float libm) (please provide -if possible- any link to/file name of context switching function for msm 7200A/7201A)

    - by klaus-vlad
    Hi, My android application uses an sqlite database and during first run it deletes some rows . The next time it runs it tries to do the same , but because the rows were previously deleted it fails . I use SQLite database browser to inspect the database ,after first run (when the rows are deleted) and I observe that the rows that no longer should exist are still in the database , even if ehwn running the app again those rows are no longer visible ! What is the cause for this behavior ?
