Android : Using Long Touch To Set Seekbar
Oct 12, 2010
I have an app that uses seekbars with buttons on either side for fine adjustments. Right now I use simple onclick events for the buttons, every click changes the seekbar 1 unit.What I would like to do is use a long press to quickly scroll, so if a user holds down a button for say 800 millis it will start adding ten units per second. What I'm thinking my approach should be is to use onKeyDown and onKeyUp events, but is there a better way? OnLongClickListener won't work as far as I can tell because it doesn't detect key-up.Is my approach correct?

I want to figure out how to detect that the user has been doing a long touch press on the screen? Most of the solutions that I see assume that the DOWN + UP sequence of events.

On my HTC Hero, when typing messages, I could always easily access characters like "?" and "!" and numerals by simply "long touching" that button. Very convenient. However, recently, that featured stopped working. I can no longer "long touch" the K-key and get a question mark like I used to.
Is this a setting that has been inadvertently turned off? If so, I can't find it.

I need to dynamically move 2 seekbars. While the user moves one, the other will have to move also accordingly to the values of the first.I've created 2 seekbars but they move independent from each other, how can i "link" them so, for ex. the second seekbar moves 1/10th of the first?

I have a SeekBar and I want the SeekBar to increment by for example 5 each time somebody drags it. The default increment is 1. How can I make it increment by more than 1? Is there a simple method?

I would like to create a seekbar for an Android app that allows the user to select a value between -5 and 5 (which maps to "strongly disagree" and "strongly agree"). how do i make a seekbar with discrete values? or is there a better UI widget i could use for this?

Does anyone know how to define a SeekBar's minimum value? Is this done in the XML layout or do I need to define it programatically?Basically I need to change my minimum value from 0 to 0.2

How to change width of a SeekBar? Below is a TableRow with two items in it, a Button and a SeekBar. How can the SeekBar be made to extend its right side to fill in the remaining width of the TableRow? Currently I have only been able to control the SeekBar width by setting it's android:layout_width attribute. Is there a way to have the LayoutManager do this automatically or can it be done programmatically? It is especially noticeable when the Orientation is changed from vertical to horizontal and the SeekBar remain stuck way over there on the left with available real estate on its right.

Has anybody tried to use the SeekBar in the window's title bar, instead of the ProgressBar, using the requestWindowFeature (Window.FEATURE_PROGRESS);?

Using progress_horizontal.xml as a base drawable for my seekbar i was able to customize it pretty well. But unfortunately i stuck with the following problem. I need my progress to be made from two horizontal lines with different color something like this http://picasaweb.google.com/manigoad/Other#5442553107070487330 . In this case a blue line and transparent line below it.So how can i make my progress to be made from two different colors.

I've been reading through the docs, and I cannot figure out how to cancel a "drag" on a Seekbar once the bar has been completed.
For example, when I drag the bar to the end, I want an event to happen. However, if I keep my finger on the screen and drag my finger past the SeekBar, it keeps firing off that event even after I reset the progress of the Seekbar. How can I prevent this action from happening?

Seems to me that I should be able to set the colors of the SeekBar thumb, slider, and progress bar in my layout xml file. However, I don't see relevant attributes for these SeekBar components. I only want to change the colors, not replace any images being used for the thumb, etc. What am I missing?

I have set negative paddings on my custom seekbar so that the round thumb image can go outside the bar, but the thumb isn't rendered out there, is there anyway to force the thumb to be drawn outside those bounds Sorry guys, I'm new to Android development, and have been tasked with fixing an existing application. The problem is that we have a custom rounded looking track bar, which consists of two rounded 'end cap' images and a 1 px background that is tiled to create the seekbar. As far as I can tell there was never one image that could be set as the background of a normal SeekBar, which is why a custom one was created. The thumb is a circle and needs to 'fit' into the end caps - the three pieces of the bar are in a relative layout. Right now I'm kind of unclear as to how the 1 px background png gets stretched as the seekbar bg, otherwise I would try to tack on the two endcaps onto that drawable some how?

I have the following layout in Android. I'm trying to make it so the seekbar is displayed ontop of the image (I have some code that makes it visible and invisible(Or rather GONE).
I was wondering if anyone could tell me how to position it so that the seekbar goes over the imageview, therefore allowing the imageview to take up the entire screen. code...

I'm trying to code a preferences widget to set a value with a SeekBar. This includes a Title, Summary, Seekbar and a TextView to show current value. All of them but Title should be shown in a second row (as standard preferences).I can't make it work. I first tried with a RelativeLayout but BELOW, etc. rules where not applied.Then I'm trying with Linear Layout + TableLayout but Seekbar doesn't catch minimum Width and remains small.

In my XML, I've set the focusable, focusableInTouchMode, clickable, and longClickable variables to false, yet I can still click and move the SeekBar. Do I need to actually change the listener events to do this? That seems so unnecessary.

Is there a way to define set values (i.e. 0%, 25%, 50%, 75%, 100%) for the seekbar widget that enables the slider to "snap" to the nearest set value? For example instead of allowing the user to position the slider at an percentage through 0-100, instead the slider can only ever be positioned at one of the five set values? While were on the subject is there an easy solution for positioning the seekbar vertically, I'd rather not hack through the seekbar source code - but I fear I may have to!

How can I layout 2 TextViews and a SeekBar on the same line in my layout xml file? I know But how can i specify TextView (one on the right, one on the left) to use only the width it needs to display the string in the TextView while SeekBar will use up the rest of the line? And i don't know the text vale of each TextView in the beginning and these TextView can change value in my application.
