Jan 22, 2009to dear all Android developers, I need to know the UTC bias of my phone to correct the UTC time information I got from a site. I have read earlier posts and already found the solution to get TimeZone information from the "System.currentTimeMillis();" method. However, I need to translate the TimeZone (as like, "Asia/Taipei") to the UTC bias that it has to be (as like, "UTC+8" or other formats). Does anyone know the actual API solution? I have surveyed android.util.TimeUtils and found nothing to do this. The worst solution may I have is to build a "TimeZone/UTC" database table to translate this..

View 6 Replies View RelatedAndroid : Delete Row In Database Table Given One Column Value - Which Is A String
Jul 22, 2010I have a table with column headings: | _id (long) | Name (String) | x (integer) | y (integer) |
I want to delete the row in the table that has Name myName.
// In onCreate
dbHelper = new DBAdapter(this);
dbHelper.open()
// Function in DBAdapter class
public boolean deleteTitleGivenName(String myName)
{return dbHelper.delete(DATABASE_TABLE_2, KEY_NAME + "=" + myName, null) > 0;}
// Function call in java code
dbHelper.deleteTitleGivenName(myName); // this is where my code fails
dbHelper.close();
Just as a note: myName is for sure in the database. Also, I can not use the ROWID since I am getting myName from a ListView.
I just started programming with Android and I have tried for days to solve this problem.
Is my WHERE clause correct (KEY_NAME + "=" + myName)?

Jan 21, 2010In Android when you upgrade a database all data is lost. I'm going through a phase of development right now that is forcing many database upgrades. I don't want to lose all my data (and have to manually re-enter it) each time I upgrade my database. I would like to store my data in flat files and load those flat files into their respective tables each time a database upgrade occurs.
My questions is: What is the best way to go about this on the Android platform? Where should I store the data files (res/raw???) What sql should I execute to load these files?

View 5 Replies View RelatedAndroid : Delete One Specific Table Of A Database - Leave Rest Intact
Apr 23, 2010I have a database where I store two different kinds of data. One table is for favorite routes, the other stores the retrieved routes from a server.
I can retrieve the routes etc just fine. But after retrieving the first Route, pressing back or HOME, and then retrieving another route, the routes table is filled with all the old routes plus the new ones.
So my question: how do I delete ONLY the routes table and not the whole database because I don't want to delete the added favorites?
I found the following function in the android docs:
public int delete (String table, String whereClause, String[] whereArgs) and I tried to implement it, but I must pass a SQLiteDataBase as an argument. But how?
I implemented: public void deleteTableRoutes(SQLiteDataBase db){ db.delete("routes", null, null);}
But I want to call this function from a different class where I have no reference to the database.. so what do I have to pass as an argument? Or how do I get a reference to my database?
I build my database upon the code example of the NotePadExample from the dev docs.How to solve this problem?
This is an extract of my class from where I want to call deleteTableRoutes(...)
private String start_from;
private String destination;
private int hour;
private int min;
private int day;
private int month;

Can you please tell me how to call the dbhelper on these activities? I am unable to do this and I am currently creating one db per each activity which is not the optimal way.

Android :: Child Views Of Particular Table Row In Table Layout?
Jul 15, 2009Here is my screen description: It is a TableLayout and it contains multiple Rows. I have set TableRow as clickable, as I want to go to next screen on click of a tableRow. Everything I am doing through Java programming (instead of XML layout, because number of TableRows changes each time) On next screen, I wanted to display all the views of that particular clicked TableRow. Here the problem i am facing is how to capture particular tableRow on onclick() even and how do I get all the textviews of that particular Row. I tried to set id at runtime, and tried to get id of view, but it's not working, giving error resourcenotfoundexception.

Android :: Adding Table Row By Inflating Does Not Take Table's Settings
Nov 4, 2010I have a table layout with a few predefined rows in it. Each row has only two columns.
Now I need to dynamically add additional rows in it.
I have two problems:
1) When programmatically inflating, I cannot set the index of the newly created row (I want it in place 'n') 2) After inflation, the inserted (actually appended) row doesn't listen to parent table's stretch column property.
So here are my questions:
q1) Can I set the place where to insert the inflated row programatically ?
q2) Why doesn't the new row inflate properly (the second column is not shown because the first column doesn't contains a TextView with fill_parent.
In the end I need the first column to occupy 80% of the screen width, and the second column remaining 20%.
q3) is that doable with programmatic row insertions ?
Android :: Dynamically Add Table Row To Table Layout
Jul 8, 2010When a button is clicked, the following method is run:
public void createTableRow(View v) {
TableLayout tl = (TableLayout) findViewById(R.id.spreadsheet);
TableRow tr = new TableRow(this);
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
TextView tvLeft = new TextView(this);
tvLeft.setLayoutParams(lp);......................
R.id.spreadsheet is an xml TableLayout. I can see from debugging that the method is being accessed, but nothing is drawn to the screen. What gives? Do I need to reset the Content View somehow?
