I have a TableRow that is empty on compile time. The tablerow is supposed to be filled with a chart generated by JFreeChart during runtime. How do I add the chart into the tablerow?

I have an Activity in which I have a TableLayout. I fill the table with TableRows in which I display TextViews. Imagine this as a classical table with text content. After the loop is finished I want to read all the heights in pixels of all the TextView in this table. I do this with getHeight(). The problem I have now is that ALL the values are 0 (zero) pixels. Even though I have text in the TextViews. The odd thing about this is, if I read the height of the exact same TextViews in an OnClickListener () then I do get the real height of the elements. Why is that so? I mean, nothing has changed in the height of those elements in the time between filling the table and firing the OnClickListener(). I really need to be able to get the height of the TextViews right after I filled the table. To get the heights upon a click is too late already for what I want to do.

The text which is longer than the screen won't automatically wrap up to be multi-line. Is it by design of TableRow? I've already set tr_content.setSingleLine(false); [update]
This has been addressed, I think I should change Fill_parent to be Wrap_content in

With the XML layout shown below, I have some views wrapped in a GestureOverlayView. As shown below, my first row is blended with the second row, as-if the first row is transposed right on top of the second. Now when I take the GestureOverlayView out of the code and leave everything else as-is, my table looks fine - the rows are separate and not on top of each other..........

I'm making a image gallery with infinite vertical and horizontal scrolling. I put images inside a ListView to make a column, and put the ListViews inside a TableRow. However, it seems that child views of TableRow is not selectable and as a result I can't select the images in my ListView (easily). Is there a way to pass the events down to child views of TableRow so they can be selectable?

I'm trying to access the textviews (for starters, eventually replace with imageviews etc) which are stored in the tablerows in the code below.
The line beginning 'log.d' was the part I was working on, trying to get it to print out the contents of the 2nd text view in the first row, but I can only get as far as selecting the tablerow using "getChildAt(i)".
Trying "getChildAt(0).getChildAt(1)" doesn't select the textview as I would have expected it to; says that it's a View and as such, doesn't have this method - though unless I'm mistaken, aren't tablerows ViewGroups, which do have this method? code...

Looks to me like every time you run your app, you insert two more rows in to the database, so the first it will have 2 rows, then 4, 6, 8, etc. On Wed, Aug 5, 2009 at 1:12 PM, saptarshi chatterjee <

I'm looking for a way to insert data into a cursor that is separate from the SQL database it retrieves the rest of the information from. Is there any way to to this, or is there a different way to add more information to a list view item? What I'm trying to do is to use a date column for each entry in the list to calculate the number of days until that date (and then put that number in the list item). I know how to get the value, but I just cant find a way to put it into the list without it being in the cursor.

View 3 Replies View RelatedI am an android application developer. I am developing an application which requires of me to use Sqlite database. I have implemented fetching the data, but i am facing problems when i try to insert data into the Sqlite database. The problem that i am having is that the new data i enter is not fetched, i.e nothing is new is being entered into the database.
this is the method i wrote in Data.java
myDataBase is an object of SQLiteDatabase
public void insertTitle(String Recipe)
ContentValues initialValues = new ContentValues();
initialValues.put(COLUMN_NAME,value);
myDataBase.insert(ZRECIPE, null, initialValues);
}
and i create an object "d" of it in Add.java, where i call the "insertTitle()" method. But nothing is inserted.
Ive developed a DB for use with my app but I've realised that I actually want extend my db to incorporate images! I will be hosting the db online but for now I am using it locally for development purposes. To create my db I have been using SQLiteBrowser, which I think is a standalone version of the Firefox SQLiteManager plugin, however I cant see a way to insert an image. I recognise that an image will have to be transfered into a byte array and stored as a blob, but rather that developing this element of the db programatically, I was wondering if the was a gui tool to help me skip this developmental element.

I'm working on a simple Android app, it is much like any other simple Database app. I have 4 EditText fields where the user inputs 4 different small pieces of text.

I know onClickListener needs to be used but not sure how to use it.
View 3 Replies View RelatedHow do I use an SQL statement on an sqllite database to insert the current date in UTC. I found the NOW function but what format is that in? This will be on mobile devices so everyone will have a different locale, however, I need a standard time format because the device will compare the dates with my server. Also, is there a way to automatically update a 'modified' field when the data in the row is changed like you can in MySQL?
View 2 Replies View RelatedI need to insert approximately one million rows of data (spread over 4 tables) - each row has one or two numeric fields, and two or three text fields (normally quite short). Single-column indexes on all the fields. After doing some tests on the emulator with a small test set, I extrapolated (assuming the last row will be inserted with a similar speed to the first row) my results to figure out that this would take about 15 hours (I have a Core 2 Duo running Vista). However, then I tried running the small test set on my Hero and I was surprised to see it run more than four times faster. I would guess it would take about 3 hours on the Hero. Alternatively, I could make the pre-populated database available as a download on the first run but this is likely to be a 120MB download. I have a few questions I'm hoping someone can help me with: 1. SQLite performance on the actual device being 4-5 times faster compared to the emulator - is this normal/expected? 2. Do the figures above generally sound fast/slow/normal (sorry this is so vague)? 3. From a user perspective - would it be best to provide a 120MB download or a 3 hour "first-time initialisation" step (plus 6MB download)?

I am trying to inject a long text entry into a SQLite database, in a TEXT field. This text has new lines in it (i.e. it spans multiple paragraphs). I can get the new lines to show up if I do the INSERT manually:
INSERT INTO "LOGENTRY" VALUES(5,40,'PLACE','line1
line2
line4
',1283990533315,'4A','TEXT','',NULL);
but if I have the equivalent text in a CSV file and attempt to .import it into the table, I get an error that it's expecting more columns than exist (as soon as the new line is encountered, the program assumes it's the end of the input and thus it's missing columns). Is this possible? Or is the only way to manually do each INSERT?
