I create a LinearLayout (orientation horizontal) which contains some TextView. The LinearLayout has a size of 1200px. When user move on, the screen, I would like to do like the Launcher application. I tried to use startScroll function. even if I set a distance, the layout doesn't move alone. Only distance did by user is slided. Does startScroll move alone all content? If yes, why my code doesn't work?

If I have 2 LinearLayouts split %50/%50 everything is fine. Weights are 1 and 1. As soon as I add a TextView inside the top LinearLayout, it stretches that layout. I use "wrap_content" as the documentation says I should when it comes to weights. As you can see the red and green should be split evenly and text on grey background should be inside red box.
Here is the code:..............
Now if I switch to "fill parent" as follows it actually works but it creates another problem. Here is the code (so far so good):
So looking at above we were forced to use "fill_parent" and we would think like we fixed the problem but here is the problem if we are using "fill_parent" (I took out the textview just to show the problem, textview doesnt make the problem go away anyways):
As you can see I assign the weights 3 (top red) and 2 (bottom green) but what actually happens is they get flipped: The red becomes 2 and bottom becomes 3. Just measure the pixels too see.
Here are the results of the 3 codes: http://imgur.com/iVt8g.jpg
I have a RelativeLayout that has two LinearLayouts in it. One is a bunch of TextViews and EditTexts that make up a form and the other is a ButtonBar that submits the form.
anyways, everything looks great in portrait, but when i switch to landscape mode the bottom TextView/EditText element is being hidden by the buttonbar.
screenshot to show the problem. as you can see some of the "email" textview and all of the email edit text are being hidden by button bar.

View 1 Replies View RelatedI have a TableLayout with a tableRow and a horizontal scroll view in the 2nd column, but the right side always gets cut off. IF i have only 1 tableRow, it works, otherwise it goes past the visible area of the screen. To simply and isolate the problem heres an xml file with the guilty culprits. It seems basic but i have been super frustrated trying to get this to work.
. for some reason Stackoverflow isnt displaying my code correctly, heres a pastebin.

If l2 is dont added to l1 than it works.
The Contacts app shows a button on the side of the screen that acts as a little thumb to allow you to quickly scroll the big list. I have a very long list that would benefit from this navigation behavior, but can't find any documentation as to how to enable it.
Is it a behavior that's built into the SDK, or must I write it myself?

View 2 Replies View RelatedI'd like to get the height of a linearlayout. I found more information in this answer
View.getWidth()/View.getHeight() won't give you a meaningful answer until the view has been measured.
How will I know that view has been measured? Is there some event for it?
Solution for me is to get layout's height in overriden onWindowFocusChanged()

I recently struggled with an apparently simple Android layout: I wanted a WebView above a Button. It worked fine with the following parameters:
WebView:
Height: wrap-content
Weight: unset (by the way, what is the default?)
Button:
Height: wrap-content
Weight: unset
However if the web page became too big it spilled out over the button. I tried various combinations of weights and heights, and all except one either completely hide the button, or partially cover it...............

View 1 Replies View RelatedI want to add some checkboxes to a LinearLayout at runtime. The orientation is vertical and I want the checkboxes to appear at the bottom. I create each checkbox like this: CheckBox box = new CheckBox(this);
Then I add the box to the current view like this: addContentView( box , params ); What should be the params to get the effect I want? So far, everything I've tried ends up overlaying the new checkboxes on top of each other and on top of the other items in the layout. I want everything stacked in a column with the new checkboxes at the bottom.
After I start the activity I am unable to scroll down to see other buttons and options in the xml defined below. Does anyone know how to make this scrollable?

To my dismay, 3rd LL get's pushed out with 2nd one filling parent layout right to the bottom. How do I achieve desired effect since I want potentially resize the outside container with the middle portion expending and contracting to accommodate the change
