View 2 RepliesI'm not big into UI programming so this may be an easy thing I overlooked. I am trying have a screen that shows 8 TextView in a 2 column x 4 row table. And, of course, I want the TextViews, that might have different lengths, to be centered. I tried this in a table layout, for obvious reasons but I feel like this is not the way to do it because it doesn't have much control where I put everything once it is in a row. Should I be using a different combinations of layouts or is there something I overlooked.

I've been pouring over this and I bet its some silly syntax typo! Or, at least I hope it is something trivial.
can I insert a new column into existing table. Because I had read somewhere that SQLite is limited on the ALTER TABLE command.
View 2 Replies View RelatedI am trying to create a basic datasheet in my application using a TableLayout. The first row contains the titles of each column. Every row thereafter is data. I would like the data to be scrollable while keeping the first title row visible (i.e. the first row would not scroll with the rest).I have tried something like the following (unsuccessfully)
View 1 Replies View RelatedSo I have an app on the market, and with an update I want to add some columns to the database. No problems so far. But I want to detect if the database in use is missing these columns, and add them if this is the case. I need this to be done dynamically and not just after the update to the new version, because the application is supposed to still be able to import older databases. Normally I would be able to use the PRAGMA query, but Im not sure how to do this with Android. I cant use execSQL since it is a query, and I cant figure out how to use PRAGMA with the query()-function.
Ofcourse I could just catch exceptions and then add the column, or always add the columns to each table before I start to work with it, but that is not a neat solution.
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)?
I am trying out this table layout in which there are three columns, each column utilizing the maximum space as they could (using strechColumn tag). Now when a column gets content which is too long, then table layout jumps of the screen.
How can i set the content of a column to wrap, so that table layout dont jump off the screen.
here is the XML code for table layout i used...
Suppose I have a view inside TableLayout, like this:
TableLayout tableLayout;
View view = (View)tableLayout.findViewById(R.id.control);

I have two files, one called "part1.txt" and another one called "part2.txt", which look like following
part1.txt part2.txt
lili like eating apple
lucy like playing football
Now i want to insert the contents of these two files into a single table with the schema
table_name(linefrompart1 varchar(100), linefrompart2 varchar(50))
My program reads the first file line by line and insert the data into the first column. But if it reads the second file and tries to insert the data line by line into the second column, it doesn't work the way i want. A table which i want should look like following
linefrompart1 linefrompart2
lili like eating apple
lucy like playing football
But instead i got the following table
linefrompart1 linefrompart2
lili null
lucy null
null like eating apple
null like playing football
Does somebody know how i can fix this problem?

Creating TableRow inside TableLayout seems to be one of the options but how to dynamically create the tableRows depending upon the type?
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.
View 2 Replies View RelatedI 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 ?
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?
