When I had a view that's in my HorizontalScrollView it leaves a blank area because it's still being considered for layout purposes. Is there a way to have it not occupy space when I hide it?

For some reason the empty view (TextView in this case) always appears, even when the List is not empty. I thought the ListView would automatically detect when to show the empty view.How can I hook up the empty view properly?
View 1 Replies View RelatedI have a ListView that with alphabetical headers for each letter. I also have an index function that brings the letter headers to the top of the screen.
My problem is when I reach the end of the list setSelection is unable to bring the last few headers to the top because it will not scroll past the end of the list.
My question is this: Is there a way to add a blank space to the end of the screen dependent on screen size? I would like to scroll until the last item in the list is at the top of the listView.
(1) I have an issue with the following code:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
On my emulator this seems to work fine. The status bar disappears and the empty space is filled with the content view. However on my Nexus One this sometimes works and sometimes the empty space remains empty/black. I tried to counteract this, but my naive approach wasn't fruitful:
handler.postDelayed(new Runnable() {.............

One more doubt is what exactly is "@hide", even if I commented it( /** @hide */) it is having some meaning( it is not visible in another classes ). When I deleted it its working fine, it is visible. what is the reason?
I tried with threads, but android throws "CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.".

But when I want to remove that item, I can't do it. I add there convertView.setVisibility(View.GONE); , but have empty item, beside hide it. I read that parameter View.INVISIBLE won't hide layout, but View.GONE have, but in my code, doesn't.

For an Android application, I'm trying to use a Spinner which, when an option is selected, will hide/display relevant View objects. For my application, these objects are an EditText and an associated TextView label for the field. Unfortunately, I can't seem to get the EditText to hide/display, and when I add it code to hide/display the TextView, I get a NullPointerException. I presume that since I am laying out the view objects in a RelativeLayout, by hiding one of the view objects, I am removing its relationship with other view objects, hence the NullPointer.
Can anyone figure out why this might be happening? Here's my code...
How do I ensure that I get the 'resize' behavior when the IME is shown/hidden?
I've included the following in my manifest:
android:windowSoftInputMode="adjustResize"
What else am I supposed to add? I've read that the container that the View is placed in should 'support resize' but what layouts support this?
WHY and how do I stop it? For example, I want to type a smiley face so I make a colon : and it automatically spaces afterward. Or it moves it to the previous word so oinstead of hello it comes out as: ) anyway it only happens in the touch keyboard. I Hate It HATE

View 1 Replies View RelatedI searched the groups to find a topic about setting horizontal scroll view's offset, but no results. Some topics talked about ScrollView, and they are not expected. Here is my question: I have a HorizontalScrollView, with LinearLayout as its child, the LinearLayout contains a custom view, I finished the onDraw method of the custom view to draw something which is longer than the screen's horizontal size, so I think HorizontalScrollView is the right widget that I need. But I do not want to display the left-most part of my custom view, such as a calendar, I can display the last week and next week in the custom view, but what I want to put in the center of the scroll view is today. So, I wonder how I should set the initial offset of the HorizontalScrollView?
View 2 Replies View RelatedI have a horizontal scroll view and there are four images in it. Now what I want is the way to detect which image is focused currently. I mean, is there any way that we can distinguish between the image that is focused and other images. Currently all the images look quite similar.
One more thing, how to move only to the next image on every swipe or fling.
Moreover, I have tried the same thing with Gallery, but I didn't found anything in the Gallery that let me move to the next view only. In Gallery, I have tried overriding the onfling method with hardcoded value for veloctiyX but with no success. Can someone let me know how to do this?
Doing the same thing with either Gallery view or HorizontalScrollview will solve my issue.
Hope to get the quick response.
I am using the HorizontalScrollView. Its working for me perfectly.
The thing i want is to disable showing of horizontal scroll bar.
How can i achieve this.
I have a HorizontalScrollView that consists of Images (Icons). I need to scroll the view in "blocks" the width of the icons, so as to never have a "piece" of the icon on the screen. I need more, but this question will give me all the other answers I need.
Does anyone have a code example to point me to for this?
I have a horizontal scroll view containing multiple Bitmaps of variable length. My question is how can i make a particular bitmap selected which in not visible on the current screen and let the horizontal scroll to scroll such that the earlier invisible Bitmap is now visible.

View 1 Replies View RelatedI have a HorizontalScrollView that has lots of views and images inside it.
The issue is that if I have lots of stuff inside it I will get a 'java.lang.OutOfMemoryError: bitmap size exceeds VM budget'
is there any way to use some kind of cache, or add/remove stuff as I move left/right so its not on memory all the time?
I have quite a complicated ListView. Each item looks something like this...
In my activity, when an item is created (getView() is called) I add dynamic TextViews to the LinearLayout inside the HorizontalScrollView (besides filling the other, simpler stuff out). Amazingly, performance is pretty good.
My problem is that when I added the HorizontalScrollView, my list items became unclickable. They don't get the orange background when clicked and they don't fire the OnItemClickedListener I have set up (to do a simple Log.d call).
How can I make my list items clickable again?
Edit: setting android:descendantFocusability="blocksDescendants" on the topmost LinearLayout seems to work. I'd like to know if there are other ways, though: what if I want focusable items in my list items?
Can anyone help with a problem I have? I created an activity (extending a list activity) and have it populating with a list of peoples names, however when I scroll up or down it automatically greys out the whole list view until you stop scrolling. Is it possible to stop this greying out from happening? I have attached an screenshot in case my description doesnt make sense. Code...
View 4 Replies View RelatedI'm just being stupid and overlooking a simple setting, but I'm pretty sure on my old HTC Hero there was an option in the settings to always load web pages in either mobile form, or the full web page (classic). Is this something that I can do in the settings on the Nexus one, because I do find it a little annoying having to regularly reload pages in "classic" view?
