Android :: Move To Next ImageView In HorizontalScrollview?
Apr 19, 2010
I 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 have a question. I've done in XML ImageView. Unfortunately, the "holds" on the left side of the screen on the phone. I wish this picture could shift to the right place. I would like to point to the X and Y position of the image shifted to the indicated place. How do I do this?

I 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?

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 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?

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?

I have an ListActivity that I wan't to add a logo to at the top above the list but I'm unsuccessful. This is what my layout looks like at the moment.
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/logo" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:drawSelectorOnTop="false"> </ListView> <TextView android:id="@+id/empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/list_empty" /> </LinearLayout>
Then I add an drawable to the ImageView logo in onCreate. I've managed to show either the ListView or the ImageView but never both of them in the same LinearLayout. Is it possible to add other views together with a ListView?

I'm using Android 1.6.
I'm wondering if there's a simple way to put text on top of an ImageView element. Specifically, I'd like to have text overlayed on top of a rectangle filled with a color gradient.
I have the following in my XML layout:
CODE:................
But the text specified in android:text doesn't show up in my view.
Any thoughts on how to overlay text on top of an image?
There might be a simpler way to do this, so I'm open to alternative suggestions but I haven't been able to find anything via the google.

I'm making a little card game in order to learn the more interesting stuff of the UI and I have a question:
I want to show 5 cards on the table, for that i have made 5 imageviews in the xml:
CODE:..................
As you might notice here, i'm doing them with an overlap since the uer should be able to pick up the last card and should therefore see it, but the other 4 are just so he'll know what was thrown lastly. my problem is: in the begining the imageviews have no src, but once i give them an image source
using CODE:..............
I dont know how i can undo it - i can't set the imageResourceId to null since it is an int type so is there something like -1 or some constant value that means null? i know about visibility, i'd rather not use it here unless i really have to, since it'll require a bunch or refactoring that i prefer to avoid...

I want to show a graphic inside my activity. A graphic thats from the www. Just like http://www.google.de/logos/olympics10-sskating-hp.png.
Wenn, in general I would download the graphic, convert it (maybe with photoshop or something), rename it (if neccassary) and copy it to my drawable folder. Then I can use its id inside my xml layout.
Now I want this procedure dynamically.
Which is the quickest way to do so?
I dont want to use WebView for this...
