I wonder if anyone knows how I shall clear and update a table on a screen. I have a TableLayout with a few rows that I create dynamically. Then I want to update that data with an update option from the Menu. Do I have to create a new activity and recreate the table or is it possible to clear it and add new rows in it.

how to get all TableRow's in a TableLayout. I already know how to add and delete rows dynamically, but I need to loop over all the rows and selectively delete some of them. I think I can come up with a work around, but I'm trying to avoid crude hacks in my app.

View 3 Replies View RelatedI have a two column TableLayout as the only child of a scroll view. The first column contains TextViews ('labels') and the second column contains EditText/Spinner/DateWidget etc ('values').
Even though I have have specified android:layout_width="fill_parent" for TableLayout, TableRow & all widgets (in 'values' column).
The screen looks perfect when the activity is created. However, when one types a really long value in the EditText, the 'values' column goes beyond the visible screen area.
Is there an equivalent view structure to the iPhone default table cell? The default table cell formats an image (icon) and text in a nice looking way. Are there suggested equivalents for Android? Is there a sample somewhere?
I want to create say 5 different types of cells in table along with identifiers and load them appropriately as per the given data depending upon the type?
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.

I've been pouring over this and I bet its some silly syntax typo! Or, at least I hope it is something trivial.
I 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?
What exactly does HTC Sense Clear Data actually clear? That may be a solution to reverting back to 5 homescreen pages instead of 7 without having to do a factory reset. Just curious as to what I am going to mess up? Will i just have to personalize the homescreen again, put widgets up, reconnect to fb, twitter, myfaves, etc. It's not going remove any 3rd party apps, just make me create new widgets, etc..?
View 3 Replies View RelatedI think that there is possible bug in TableLayout SDK 1.0 rc2 when constructing table from code. It seams that the weight or height attribute is not respected when rendering the layout.
The XML view creates a table with row at the top and row at the bottom of the screen which is what supposed to happen, so I created this same table via code but the results are not what were expected. Maybe I am missing something but it seams OK, all LayoutParams are this same.
Sample Code ...
If anyone else can confirm this I will post this as a bug.

View 5 Replies View RelatedI want to design a table whose first column items remain fixed when user scrolls horizontally, but should scroll when the user scrolls vertically. Similarly the first row items remain fixed when user scrolls vertically, but should scroll when the user scrolls horizontally. Can this be achieved using a TableLayout? Or is there any other combination of widgets that I could use?

Here is the xml file of my Android widget: http://pastebin.com/Kqxs5t9E
This code is showing me some good results in Eclipse, but as soon as I sent the file to my device and try to add the widget to my homescreen I get this error code and the widget showing: "Problem Loading the Widget":

So what? I cannot use a Tablelayout within a widget?
What is the best solution so? I can create a lot of relativelayout but I guess that's not a good idea.

I'd like to have column headings in a TableLayout and I'd like those headings to remain visible when the table is scrolled vertically. One option is to create a separate TableLayout just for the column headings but it's a little complicated keeping the column widths consistent between the two tables.
View 2 Replies View RelatedI have a TableLayout on one Android Activity UI. It has two columns. Now I need to add a new row, and put an EditText box in second column of that new row. And also, I want that EditText full fill the whole cell. I have some code like this:
CODE:..........................
It puts the EditText in the second column fine, but the EditText is too small. I tried to use etText.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); but that seems to disabled the TableRow.LayoutParams setting. I guess each control can only have one LayoutParamas setting. So, how to make the EditText as a 4 lines text editor and also make sure it is in the second column of that row?
I have a TableLayout with three columns that represents a form with
requiredSymbol | label | inputfield.
I want the input field to fill the remaining width of the screen right to the label. So far the only solution I found is this
CODE:....................
The maxWidth needs to be there are some value, which is actually ignored. Then the stretchColumns value does its thing nicely. Note that this also works if the content of the EditText would otherwise make the table span beyond the screen border (imho a bug..).
This works nicely now but seems a little bit of a hack to me. Is there a better way?
I am having problems creating a table layout with 4 columns, that span horizontally.
I want my Row to look like this: AAPL | 200.00 | Image Divider | 1.53 (+1.5%)

I have four buttons arranged in a 2x2 TableLayout. These buttons each have an image on the left and some text. The buttons display fine in the emulator for 1.5, and for 2.2, but when testing with 1.6 the two buttons in the righthand column are cropped so that they are missing their righthand edge (the padding to the right of the text is missing and the button ends abruptly with squared off corners rather than rounded ones). There is plenty of room for the TableLayout to expand to accommodate the full width of the buttons. This happens for all screen sizes.
The layout looks like this and itself appears within a RelativeLayout:
CODE:...............
The buttons are styled as follows:

I'm assuming this is a 1.6-specific bug. Has anybody else come across this problem? Any suggestions for work-arounds?
I've had the opportunity to try it with Android 2.1 (both on the emulator and a device), and the problem happens there too. So 1.5 good, 1.6 bad, 2.1 bad, 2.2 good.
I am using Tablerow+TextView to make a simple view for blog posts and their replies. In each TableRow I put a TextView in. Now I have two issues:

This has been addressed, I think I should change Fill_parent to be Wrap_content in
