Android :: Utc Timezone - Translate Database Table

Jan 22, 2009

to 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..

Android :: Backup Table To Local Database File?

Oct 20, 2009

I am working on a project for a belgium Tv Guide. Now I download a database (.db) file from a server to the sdcard to work with. In this database are 2 tabels, tvchannels and tvprograms. Now I can do several updates to the tvchannels table and i want to make a backup of this table to a lokal database file. How can i do that?

I want to backup this database table and when the new database file (tvgids.db) is downloaded I want to replace the tvchannels database (from downloaded database file) with the backup from tvchannels..

Android : Delete Row In Database Table Given One Column Value - Which Is A String

Jul 22, 2010

I 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)?

Android : Way To Load Flat Files Into Droid Database Table

Jan 21, 2010

In 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?

Android : Delete One Specific Table Of A Database - Leave Rest Intact

Apr 23, 2010

I 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;
private Source source;
private List<Element> tempList;
private List<Element> routes;
private String startT = "";
private String arrivalT = "";
private String duration = "";
private String line = "";
private boolean first=true;
private List<ResultElement> finalResult;
private List<Element> results;
private DbAdapter mDbHelper;

Android :: Insert Data On Sqlite Database Table From Word Or Excel Document?

May 22, 2010

In my project, I would like to create a database with single table. I would also like to insert data on this table from word or excel document. is it possible? if so please how can I do it? some code snippets would be of great help. I have four different activities which I would like them to interact with this single table. the first is the main activity and its purpose is just to launch the other three activities according to user choice. so it has no interaction with the DB. but the other three activities will read from the table whenever called. 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, 2009

Here 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, 2010

I 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, 2010

When 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?
