How to Detect Long Press in Android?
A Long Press refers to pressing a physical button or tap a virtual button on a touchscreen and holding it down for a second or two. Employed on touchscreens, smartphones, tablets, and smartwatches, the long press or long tap increases the user interface’s flexibility. The typical “short press” or “short tap” performs one operation, while pressing/tapping and holding that same button for a short time activates another. Long pressing lets you get some information, download photos from the web, edit pictures, and more.
Where can we use this feature?
As mentioned, a long press can be used for plenty of applications, some are listed below:
- Get information
- Download photos
- Edit pictures
- Copy, Cut, Paste operations on Text View
Through this article, we want to extend our knowledge regarding the long press on a Button as well as a view such as a TextView in Android. We have implemented a method that would detect a long press for a certain duration, and if the criteria are fulfilled, a Toast would be generated. Note that we are going to implement this project using the Kotlin language.
