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)

Android :: Unable To Add Subview To Linear Layout With Wrap Content

Aug 29, 2010

I'm using data to build elements of a ViewGroup. The ViewGroup are LinearLayouts, except the leaves, which are TextViews. Because Data draws the hierarchy, I inflate the LinearLayouts and TextViews from individual XML files programatically on the fly.

My Problem:
When I create a LinearLayout with the attribute wrap_content, then inflate a TextView or other LinearLayout into it, I can't get the parents (or enough of them, anyway) to redraw, respecting the new view. These LinearLayouts always seem to come out at 0 size, because when they are first created (before their children are inflated), they wrap around nothing. I've tried calling some stock methods of ViewGroup but nothing seems to work.

Android :: Table Layout Setup - Scrolling Like Spreadsheet

Aug 30, 2010

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?

Android :: Two Column Table

Jul 29, 2010

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.

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 :: 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?

Android :: Detect If A Table Contains A Column In Droid / Sqlite

Apr 20, 2010

So 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.

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 :: Insert Data In To A Single Column Of An Existed Table?

Jul 15, 2010

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?

Android :: Android - ListView Items Not Grow To Wrap Their Content

Nov 2, 2009

I have a rather complex ListView, with variable list item heights. Under certain conditions, I need to display an additional view in a list item, which is hidden by default (View.GONE). By enabling it (View.VISIBLE), the list item grows in height (or at least it's supposed to).

The problem:
Even though I declare the item's root layout to wrap_content, and each component in the item to fill_parent, the view I hide/show which is supposed to change the item's height is simply cut off at the bottom instead of its parent (the item layout) growing in height to fully display it.

Are there any gotchas related to ListViews and item layouts and item height which I may have missed?

Some more observations:

For testing purposes I have now reduced the list item layout to just contain the root LinearLayout and an ImageView. When I set the LinearLayout height to e.g. 200dip and the ImageView to fill_parent, I would have expected the ImageView to grow until it hits the 200dip limit set by its parent.

However, the image will instead be only ever as tall as its bitmap resource (as if I had set it to wrap_content) and the whole list item will be of the same height (i.e. as if I had set it to wrap_content, too).

If however I set the image height to e.g. 200dip, then the list item will grow in height, and so will the item layout.

In other words, the layout_height of the list item layout is completely ignored, and so is any height value on ImageView other than a hard-coded pixel value.

Android :: How To Return Non-table-oriented Data From A Content Provider

Mar 27, 2009

I'm writing a content provider that returns data about game sessions. This data comes from an SQLite table. However, the client that consumes it will also want summary data: total wins, current/best winning streak, and so on. I'm not sure which approach to use.

* Possible Approach 1: Do nothing, let the client calculate what it needs.

The client could step through the whole table and calculate statistics itself. However, it's inefficient to send the entire database over the content provider link if the client only wants the summaries; this may also be prone to bugs because each client has to reimplement the summary calculations.

* Possible Approach 2: Separate content URIs for summary data.

The client could ask for a URI like content://myapp/summary/totalwins and get back a text/plain stream containing the number of wins. This seems like a big hassle to implement on both ends, though. Or it could ask for a URI like content://myapp/summary and get back an XML stream containing all the summary data, but this isn't much simpler.

* Possible Approach 3: A phony table.

The client could ask for a URI like content://myapp/summary and get back a cursor over a single row, with each summary value having its own column. This would not be an SQLite cursor but a custom in-memory cursor. It seems a little unnatural to use a table metaphor when there's always exactly one row, though.

* Possible Approach 4: The extras bundle.

Cursor has a getExtras() method that returns a bundle. The client could make a request for the main URI, content://myapp/sessions, and then just look at the extras bundle instead of reading any rows. However, there's no setExtras() method, so I'm stuck with whatever bundle object SQLite puts in there - and if it's Bundle.EMPTY, I'm out of luck.

Android :: Table Row As Linear Layout

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...
