View 2 Replies View RelatedAs far as I have read in the Internet and official documentation, it isn't possible to make a scrollable app widget. Also all my tries failed. I even tried to subclass TextView to implement my own scroll method, but nothing worked.Are there any ways to achieve that? there are solutions if you use for example htc sense or home desktop ++, but i want to make it available to other users which don't use this

is it possible to make an entire linear layout scrollable when it needs to be? (when all of the elements in the layout don't fit on the main screen)?I know it is doable with views, etc.but is there a way to incorporate everything on the layout to be scrollable at the same time?Maybe scrollable is not the right term. basically - if one of the elements (a button in this case) doesn't entirely make it onto the main screen of the phone and I need to slide a finger down to access it if that makes sense.

When the keyboard pops up though, it covers the submit button on the bottom. I can make the entire layout scrollable, but then you can scroll too far. How do I make it so that, when the keyboard is up, you can scroll down to see other information (like buttons, textviews, etc)?

View 8 Replies View RelatedI'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now.The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application.Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through.I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful.EDIT: To clarify, the goal is to have ONE item on screen at a time. If you scroll between one item and the next, the previous one leaves the screen, and the new one snaps into place. So if it were a photo gallery, each spot on the grid would take up the entire screen size, approximately, and would be flung out of the viewable area when you slide across to the next photo, in either direction. (Photos are just an example for illustration purposes)

</TableLayout> I would like the Listview to grow until the available space is used, then scroll as it coninues to grow. This works fine when the table row with the Listview is the last one in the TableLayout: However, having the Add button at the top of the list is not very intuitive. When I move the "fixed" table rows to the bottom, the ListView will push them off the screen once it grows to a point where it should scroll. The ListView will only then begin to scroll when there is nothing else left that can be pushed off the screen:How can I change my layout so that the table rows with the button and the EditText view remain visible?

I'm getting started with OpenGL ES on Android and I'd looking to learn some techniques to have a game map larger than the visible area.I'm assuming I've somehow got to ensure that the system isn't rendering the entire scene, including what's outside of the visible area.I'm just not sure how I'd go about designing this.This is for simple 2D top-down tile based rendering. No real 3D except what's inherent in OpenGL ES itself.Would anyone be able to get me started on the right path? Are there options that might scale nicely when I decide to start tilting my perspective and doing 3D?
View 1 Replies View RelatedI know it's considered taboo to place a ListView inside a scrolling container, so is there any "proper" way to accomplish scrolling of a container that has a ListView child in it? An example layout would look something like:
Header
---
"Sub" header
---
ListView with list items
---
Footer
Header and Footer need to remain static on the screen, and the middle content (Subheader and ListView) should scroll between them. I can't have just the ListView scrollable, because the subheader takes up too much space. As it is currently, the Header comes from an <include />, the Subheader contains several views including an Image and some text, and the ListView (actually part of a ViewFlipper) would contain an indeterminate number of items. The Footer has a couple buttons/tabs that are used to control the ViewFlipper (only one of the views in the flipper is a ListView).
The only way I can think of to accomplish this efficiently would be to place the Subheader inside the ListView as the first item -- is there any better way?
I am displaying text in a textview that appears to be too long to fit into one screen. I need to make my TextView scrollable. How can i do that? Here is the code

I've just started playing with Android in the last few days and have begun to put together a simple application. I am struggling to work out whether I'm doing things the "right" way or just making life difficult for myself.The app displays a series of connected nodes on the screen, similar to a mind-map. I want to be able to tap the nodes in order to edit them. When the map of nodes becomes larger than the screen, I need to be able to scroll on both X and Y axes as needed to see the whole map. Image of current implementation at http://ubergeek.org.uk/images/nodetest.png.Currently I don't have scrolling working, however I assume that I can do that by making the root view a ScrollView and sticking an AbsoluteLayout inside that (though it's deprecated, I wish to place objects at specific X/Y coordinates).The nodes themselves are currently each a pair of roundrects (one for the outline and one for the fill) and a drawText and are being drawn in the main activity's onDraw(). In order to make these clickable buttons I believe I need to create a custom view for the button in order to use its onClick() events. I can then create a view object for each of my nodes and add them to the AbsoluteLayout view.Does this sound like a reasonable way to do it in Android, or is this a horrible abuse of the API?

View 3 Replies View RelatedMany people would like to see scrollable widgets on their Home. As you may know, current Android stock Home doesn't support it, and HTC Sense doesn't provide any API.We propose to create an open source standard for an Home extension code allowing devs to create 3rd party widgets which support scrolling (list view).The principe have been implemented, and succesfully tested in Home++ and Pure messenger widget.Now, after discussing with other Home creators, we'd like to generalize this and include it in other Home applications. Few other Home applications devs are already integrating the Home++ code to evaluate this (FreedHome, Tag Home and HelixLauncher 1).Here is the list of interested parteners: - Helix Launcher - FreedHome - Tag Home - ADW Launcher - LauncherPro beta - GDE.During this first phase we'd like to focus on scrollable widgets but other extensions could be imagined (animations, gestures)If Google wants to use it for the next Android release, we would be very happy, but for now, the goal is to include it in a large number of alternative Home applications.

View 1 Replies View RelatedI want to implement an activity where the only thing you see is a big image, which can be scrolled horizontally and vertically.On Top of that image I want to display buttons, that can be clicked and trigger certain actions (like creating an intent to start a new activity). First I was thinking about a ScrollView, that has a FrameLayout as a child. The FrameLayout could have the image as a background and can have the buttons as childs. Because I know the position of my buttons exactly I could place them with absolute coordinates. Here is my first code:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout
android:layout_width="1298px"
android:layout_height="945px"......................
I'm trying to implement something very similar in my application, but looks like it's impossible to do this with standard components. I read several topics about such scrolling feature in the group, but all the topics ends with suggestion to write your own scroll view. I wonder did somebody implement such scroll view already? Or can somebody provide a brief how-to on this particular feature. I think any information on this would be very appreciated by many members of the group.
View 4 Replies View RelatedAny insights/pointers regarding creating a layout like this. I have wasted quite a bit of time on this. I want to create a vertical linearlayout which has multiple ExpandableListViews separated by TextViews.
CODE:.........................
I tried the following approaches but each of them has one shortcoming or the other:
1. Add TextView and ExpandableListViews to a linearlayout. The problem with this approach is that LinearLayout by default is unscrollable.
Adding the LinearLayout to a ScrollableView creates even more issues because ListViews handle their own scrolling behavior.
2. I tried using a single ExpandableListView to model the above layout but the problem is that setGroupIndicator applies to the entire ExpandableListView, not a specific group.
