I 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)

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);
How can I find out the view's row/column within the TableLayout?
Is it possible for my android application to dynamically adjust the no of column and no of row of my TableLayout based on orientation?
For example, when in landscape mode, the TableLayout is 3x2 and when
in portrait mode, the TableLayout is 2x3?
I'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.
View 2 Replies View RelatedHere 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 RelatedWhen 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?
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 RelatedHow to create a table without primary key but it has one autoincrement column.
View 2 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 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?

I'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now.The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application.Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through.I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful.EDIT: To clarify, the goal is to have ONE item on screen at a time. If you scroll between one item and the next, the previous one leaves the screen, and the new one snaps into place. So if it were a photo gallery, each spot on the grid would take up the entire screen size, approximately, and would be flung out of the viewable area when you slide across to the next photo, in either direction. (Photos are just an example for illustration purposes)

View 1 Replies View Relatedis it possible to make an entire linear layout scrollable when it needs to be? (when all of the elements in the layout don't fit on the main screen)?I know it is doable with views, etc.but is there a way to incorporate everything on the layout to be scrollable at the same time?Maybe scrollable is not the right term. basically - if one of the elements (a button in this case) doesn't entirely make it onto the main screen of the phone and I need to slide a finger down to access it if that makes sense.

Any insights/pointers regarding creating a layout like this. I have wasted quite a bit of time on this. I want to create a vertical linearlayout which has multiple ExpandableListViews separated by TextViews.
CODE:.........................
I tried the following approaches but each of them has one shortcoming or the other:
1. Add TextView and ExpandableListViews to a linearlayout. The problem with this approach is that LinearLayout by default is unscrollable.
Adding the LinearLayout to a ScrollableView creates even more issues because ListViews handle their own scrolling behavior.
2. I tried using a single ExpandableListView to model the above layout but the problem is that setGroupIndicator applies to the entire ExpandableListView, not a specific group.
I have 3 text views in a layout, where the text clips a tad on the bottom on my droid 2...how can I ensure that the whole text is viewable and the user can scroll down (simply with their finger) to see the rest of my text?

I have a relative layout which looks like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="@+id/nameText"
android:layout_width="wrap_content"......................
I've noticed a strange thing with a TableRow.
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stretchColumns="0">
<TableRow
android:background="#9932cc"
android:minHeight="40px"
android:orientation="horizontal">...........
This code doesn't work properly as TextView text1 doesn't wrap it just stretches beyond the screen. I've managed to get it working by embedding this LinearLayout into RelativeLayout but it seems to be the least elegant solution plus I don't understand what's wrong with the code above...

I want to set up a table layout that scrolls like a spreadsheet. The top row of column headings should scroll horizontally but be pinned when scrolling vertically. The left-most column of row labels should scroll vertically but be pinned when scrolling horizontally. The number of rows and columns is not known in advance. Does anyone know of an example of this? Are there settings in TableLayout that can turn on this scroll behavior? Is there, perhaps, a more advanced widget than TableLayout that can produce this type of scrolling? Are there some tricks I can do with a ScrollView to get this behavior?

I'm new in Android. I searched a lot to get a table with borders, but I am not getting result.
I want a table with two colums, borders, white backgroud in table. first colums should be right aligned and second column should be left aligned.
With TableLayout, rest of things can be done, but not I can get table with border in display.
