I'm searching for an intuitive way to change the order of a list. I don't think that drag'n'drop would be a good solution, because it's a mobile browser based application and no user would try to long click something for drag'n'drop in a browser. My first attempt is something like a popup, which opens when the user clicks on the item number.
But I still think there is a better solution to do this and I hope you can help me.
Long click and drag seems to be the best solution. One or two below:
Also consider clicking - icon on the right side indicating, that you can change order. After click moving up / down is activted.
I'd consider some menu action for activation of editing order. Especially if editing order is not a core functionality of your app.
The problem with drag-and-drop is that you can't be sure about the user recognizing this a functionality. If you provide some kind of "first time tutorial", and the lists tend to fit in the screen, it's the best option.
Comparing d&d with the arrows, the latter are more intuitive but also more tedious because of the number of taps that might be required.
If lists are long enough to keep a lot of items "below the fold" frequently, an option is to put some control that let you choose "After X" / "Before X" so the user doesn't have to drag&drop or push the arrows eternally.
