Join Dan Gookin for an in-depth discussion in this video Mastering the touch screen, part of Android Essential Training (2015).
- What you see here is a typical Android home screen. I'm going to use it as well as some other apps to demonstrate touch screen techniques. Later movies describe the home screen as well as the apps I'll be using. To swipe, you touch the screen and slide your finger in any direction. On the home screen, swiping left or right displays additional home screen pages. Another basic touch screen technique is the touch or tap. Just as it sounds, you touch or tap the screen, usually you tap an icon or button.
For example, here I'm tapping the Chrome app to start the web browser. To scroll a webpage, use the swipe technique. Swipe up and down to scroll. To return to the home screen, tap the home navigation icon. A long press is when you tap and hold like you're pressing a button. For example, long pressing the home navigation icon lets you access the Google Now app on some Androids. Long press a blank part of the home screen to view the home screen menu.
I'll tap the back navigation icon to dismiss the menu. A drag is a combination long press and swipe. It's used to move things around. The long press picks something up and the drag moves the objects. For example, you can drag to rearrange icons on the home screen. Long press to lift the icon, then keeping your finger down, move it to another spot, lift you finger to complete the drag operation. A double tap consists of two taps in a row. In most apps, double tap zooms in.
I'll tap the Maps app icon to start that app and view a map. Double tap the screen to zoom in on a particular location. Keep double tapping to continue zooming in. A pinch involves two fingers. Touch the screen using your thumb and forefingers and then bring the fingers together. In most apps such as a Maps app, the pinch is used to zoom out making the item you're viewing appear smaller. Repeat the pinch to keep zooming out.
The spread is the opposite of a pinch. Touch the screen with your index and thumb together and then spread your fingers apart. The spread operation serves to zoom in making the item shown on the screen appear larger. You can zoom in on the map when viewing photos or a webpage for example. The spread is more reliable than using double tap to zoom in. The final touch screen technique is the rotate. Like the pinch and spread, it involves two fingers touching the screen at the same time. Although in this case, you twist your fingers around the central object as if you're turning the dial on a safe.
In the Maps app, the rotate is used to reorient the map. Those are the basic touch screen techniques. Swipe, tap, long press, drag, double tap pinch, spread and rotate. To return to the home screen, tap the home navigation icon.
