Is it possible to take a csv file stored in the res/raw resource directory and use it to populate a table in the sqlite3 database? My thought was that, if there was a way to do a bulk import for the entire file into the table then that would be cleaner and faster than iterating over each line in the file and executing individual insert statements...
but I'm having trouble applying those statements in my Android application. My first thought was to try something like the following...but no luck:
db.execSQL("CREATE TABLE " + TABLE_NAME + "(id INTEGER PRIMARY KEY, name TEXT)");
db.execSQL(".mode csv");
db.execSQL(".import res/raw/MyFile.csv " + TABLE_NAME);...............
I'm trying to do a very simple thing (showing a populated listView) but m not able. My code is not working and i cant find what's wrong, so i hope someone else can help me :)
My XML where i have the listView defined code...
When i launch the app, it goes fine, the TextView of the XML is showed but no signs of the ListView... Am i missing something?
Basically I am trying to recreate the default contact screen when you click on "+" button another row of Phone number added to the list. Right now I have an ImageView as the "+" button and a ListView to contain the list of phone numbers. The problem is that the ListView doesn't expand when I add more item into the list. I could build the same look with LinearLayout but how can I save all those numbers that way? Below is the layout of the item that will be inflate with custom Adapter:
<?xml version="1.0" encoding="utf-8"?> <TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="60px"
android:stretchColumns="1" android:background="#FFFFFFFF"
android:gravity="center_vertical"> <TableRow>
<Button android:id="@+id/type" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:paddingLeft="10dp"
android:text="Home" /> <RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:paddingLeft="10dp"
android:paddingRight="10dp" >
<EditText android:id="@+id/value" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" android:text="" android:hint="Name"
android:lines="1" android:textSize="10pt" android:typeface="sans"
android:textColor="#FF000000" android:gravity="left" /
</RelativeLayout> <ImageView android:id="@+id/del"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentRight="true" android:layout_alignParentTop="true"
android:paddingRight="14dp" android:src="@android:drawable/ic_delete" />
</TableRow> </TableLayout>
This is the ListView portion.
<ListView android:id="@+id/phoneList" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#FFFFFFFF"
android:scrollbars="none" />
So far we have developed apps in android that create database on runtime. We like to know how can we access a pre-built or existing database/sqlite file in our android app?
View 1 Replies View RelatedI try to increase the value of an integer key in a row in my table. However, nothing really seems to happen.
db.rawQuery("UPDATE table SET key = key + 1 WHERE name=?", new String[] {name});
However, this code works fine (just sets the key to a hard-coded value):
ContentValues values = new ContentValues();
values.put("key", 2);
db.update("table", values, "name=?", new String[] {name});
Also tried '?' instead of just ?, but it resulted just in a run-time error.
I have array list of geopoints
List<GeoPoint> geoPointsArray = new ArrayList<GeoPoint>();
I want to put geoPointsArray array in to SQLite database and then fetch the data back as an array.
Now I use ContentValues for insert into array as:

initialValues.put(KEY_TIME, time);
db.insert(tableName, null, initialValues);

View 1 Replies View RelatedI want to know when a close method of a sqlite database should be called in a life cycle, since the NotePad sample in the sdk (http://developer.android.com/resources/tutorials/notepad/index.html) doesn't call NotesDbAdapter.close(), it implements that method though.
My application accesses the db not so frequently, but some, it depends on user requests. I think I should open the db at the onCreate, and close it at the onDestroy. Is that a good practice?
How can I obtain the value of a boolean field in a sqlite database in android?
I usually use getString() getInt() etc to get the values of my fields, but there does not seem to be a getBoolean() method. Any takers?
How large can be the database of my Android app? Is there a limit?
For performance reasons, I don't want to store the database on the SD card.
I'm trying to insert values on Android SQLite Database. The question is, Iḿ trying to insert a word, the table has 3 columns, ID, WORD, COUNT. When I insert a word in the database, some method will verify if this word exists on the database. If yes, it will increment the value of COUNT for this word.

View 2 Replies View RelatedI'm currently developing a Field-Service application that stores data in the local sqlite database on an android device. At some point, usually after completing the data collection rounds, the local sqlite db is to be synchronized to a remote sybase db on the server.Any suggestions as to how this could be achieved or engineered as a solution? Or even better, are there alternatives to synchronizing data in such an application?

View 9 Replies View RelatedI'm doing a application that will use a database with serialized object. The objects will be already serialized and the user will just display things.

View 3 Replies View RelatedI put my database field in "assets" folder. And use the code from this blog to copy the database to "/data/data/my_packname/databases/", (This copy code i run it in the onCreate() method when i run this app) then use select * from ... to get data. But it gives me the exception: no such table. Someone told me that if i am attempting to copy the file in SQLiteOpenHelper's onCreate(), it's too late. So the copy file code can not copy the complete file. So i need to use adb or ddms to pull the database first? So, Anyone can teach me how to use my own databse?

public void delete(String id, String name, String phonenumber, String time, String message)
{
String[] args={id};
getWritableDatabase().delete("texts", "_ID=?", args);
}
It works fine, and deletes the specified row. However, I also want to implement it so that I can delete the most recent (earliest date) entry in the database, which should be at the top of the table. I know I can do this by altering the last 2 parameters of delete, but I cannot figure out what to change them to.

View 6 Replies View RelatedIs it really necessary to close an SQLite database that your activity has opened (database is in local memory or on SD card)? I would think it would be good practice, but I noticed that the Android samples such as the Notepad tutorial and SearchableDictionary sample do not do this. I've also seen sample code where the database is consistently opened, read from, and closed, but that would seem to add unnecessary overhead.
