Android :: Setting A Scrollbar Position
Jul 6, 2009
Is it possible to change a scrollbar's location programatically? I have a ListView and I want to set the position of the scrollbar in my code.
Also, I'm using the Instrumentation framework for feature testing. I was wondering if it's possible to generate a "drag" movement with Instrumentation. By dragging, I mean holding the mouse button in the emulator window, and scrolling (which would make to scrollbar move). I found the way to do some clicks, but I can't find out how to generate the drag motion.

When I load Google Maps and it first locates me, it centers the map on my location. Once I am travelling, the map does not follow my location. My location dot will go right off the map and I have to manually drag the map to see the next section I am now driving on.
Is there a setting to make Google Maps follow my position while driving?

On my htc i was looking through display, i see g sensor calibration and i perform this calibration and after i do so the screen seems to have a delay when switch from the horizontal position to the vertical position. its weird because when i switch to the phone horizontally it switch normally and responds fast. but when i switch back to vertically it takes almost 7 seconds to actually switch back, sometimes it switch within 2 or 3 secs but never as quick as switching horizontally.

If you're already updated, shut down and repower (soft reboot) should do the trick. I actually updated my phone and after it started to do this. I restarted the phone plenty of times i even took the battery out for 30 seconds. It only does it when im texting on the browser, basically everything but the camera. He camera screen rotation is perfect. I even rooted the phone but i havent figured out how to use the root to fix the problem. Should i do a firmware update? Because i just did the htc software update.

The problem appears in Android 2.2. It seems cool because it can auto-hide.But I don't like it quite much because the bar is an indicator for "Whether there is more content not present on the widget". Hiding it maybe neat, but may get the users wrong sometimes. In ListView, I find it a fatal bug at all. When there is more content to show, no scrollbar present, AND when wipe the screen down-wards, no scroolbar appears. Only when use the traceball or Dpad to move focus, there appears the scrollbar. BUT THERE IS WORSE: when you wipe down-wards to move the scrollbar down, nothing happens! The touch feature is almost disabled here.

I made a small webpage with a scrollable div. When I load it in a browser, it works fine. But when I load it in a webview inside Android, it doesn't let me scroll the div. Is there a workaround for this or do I have to use a different design? I am talking about websites like this.

How can I autohide scrollbar in ListView? I thought there would be an autohide attribute for ListView but there isn't. What I want to do is scrollbar is hidden at first when I touch the listview, scrollbar appears 2~3 seconds after the touch off, scrollbar disappears again.

There are arrows in scrollbar drawable image and when clicked on them,particular list item should get selected.
So I need to use custom scrollbar for this requirement.

Is it possible to set a delay at which the scroll bar at the right side appears? The idea is that when the user begins to scroll, the scroll bar does not show up immediately, but if the user scrolls long enough.
I was looking for some time now and found just a getter method getScrollDefaultDelay (), which gets the time in ms when the scroll bar dissapears. How could I control the delay in my case?

I want to hide a listview's scrollbar when the listview isn't scrolling and show it when scrolling. I know this can be done very easy by setting "android:fadeScrollbars" as an application style if the API is 5 or newer. But I want the feature to be available on all android devices. So I've implemented the "setOnScrollListener" method, and switched the scrollbar visibility using the setVerticalScrollBarEnabled method. This works great on G2. The problem is that on Motorola Milestone the SCROLL_STATE_IDLE event isn't received when the scrolling stops, and so the scrollbar remains visible.

Is there a way to replace the scrollbar drawable in an application (i.e. I have a customized scrollbar view that I would like to use instead of the default gray scrollbar that comes with the Android framework). I looked through I believe all of the android attributes and none seem to support it (at least the simplest way I know how which I would assume would be setting a drawable to some android attribute). If not and say it requires a change in the framework, where would I start looking for it (in the framework)?

I created a user form which fits the window in vertical orientation. When the user slides the keyboard the form doesn't fit the screen (horizontal orientation). I tried to add the scrollbar but it is not visible. I would appreciate if anyone could show how to modify the following layout file in order to display scrollbar when the orientation is set to horizontal.

I have a Adapter View derived class (say GridLayout) in which I arrange views in a grid. When items in the grid exceed the height of the GridLayout( or screen) I want a scrollbar to appear. I have handled scrolling in onTouchEvent. But the problem is the scrollbars don't appear. I have set the vertical scrollbar to be enabled, but no use. The docs say the scrollbar appears every time the scrollTo or scrollBy methods are called.

I need to implement a screen having around 1000 thumbnails. This screen should support gesture based scrolling as well as fast scrolling using a scrollbar with thumb. So if user want to move from page 1 to page 100 he can just drag the thumb and reach there. But there is no such control in Android. There is seek bar but its look and feel is not similar to what I want. I also want to flick and swipe functionality which can be inherited using horizontalscrollbar. So i want to add functionality of horizontal scroolbar as well as of seekbar in my application.

I have a plain vanilla layout:
<ScrollView>
<TableLayout>
<TableRow>
but the content gets clipped by the ScrollViews scrollbar.
This link illustrates the issue:

How to avoid content clipped by ScrollView scrollbar ?
Edit: Adding android:layout_marginRight="5dip" on ScrollView leaves ugly gap on righthand side of emulator screen. See below.

I'm having a little problem with a ListView scrollbar. The scrollbar appears at the side as expected, but how do I get the scrollbar to expand and become controllable in the same way it behaves in the Contact list? Ideally I'd like all the Contacts list functionality for my app - i.e. to allow me to control the scrollbar directly with a finger and to show the first letter of the list elements you're currently scrolled to.
