The context here is a hybrid Android (v 4.4.x+) app. I have started with the code for the rather well written and documented noUISlider which I have modified to make it look more like a "Material" slider. My choice of this control was dictated by the fact that I require linear and logarithmic sliders that are also easy to control via script. Take a look at the image below
The slider range needs to be altered in half hour increments. This works just fine when I use the underlying code in a web app and use a mouse to move the slider around. However, in the Android phone app (i.e. touch screen) it is well nigh impossible to accurately move the slider - not without a few failed experiments when it gets a too low/too high value. About the only way I can think of addressing this problem is placing, rather fat, + & - buttons at either end of the slider which would at best be clumsy and ugly. Perhaps someone here might be able to suggest more functional and aesthetic alternatives?
