gesture swipe

Why let the user use scroll when sliding (fling) is more efficient than moving (scroll)? On mobile devices with a small footprint and a lot of data, it is difficult to display the content scroll far behind, in which case fling is more appropriate.Note: Scroll indicates how much distance the finger slips, and how much distance the interface follows, while the fling is based on your sliding direction and weight, and automatically slides a distance.Filing gestures are widely used in Android interac

When developing an Android program, sometimes you need to monitor your finger to slide the screen, and when your finger slides up and down in different directions to make a different response, how do you achieve that?Using the gesture monitor provided by Android can be easily implemented, directly on the code (tested pass)public class Cbmainactivity extends Activity implements android.view.gesturedetector.ongesturelistener{// Defines a

(rotate), swipe (sliding, fast moving, is used to monitor the direction of the slide), Pan (drag, slow move, is used to monitor the amount of offset) and longpress (Long Press). For example, you can add in the Viewdidload function: -(void) viewdidload { [super viewdidload]; Do no additional setup after loading the view from its nib.

. Returns: True if the event is consumed, else false General meaning:E1 represents an event that is triggered by the moment the finger is pressed,E2 represents an event triggered when the finger is not bouncing and movingThe remaining two parameters roughly mean the number of pixels per second moving in the X, y direction.So, by E1 and E2, you can create a judging condition for gestures.Simple left and right swipe

First, let's take a look, this is the Sina Weibo tab slide effect. We can swipe the gesture or click on the header above to toggle it. In this same way, the white bar is moved to the corresponding tab header. This is an animated effect, and the white stripes are slowly sliding past. Well, then we'll do it. Second, before we begin, we must first know a control, Viewpager. It is a class of an add-on package t

1.2. Function realization2.1 Layout structureThe Framelayout layout is used here, and its first child textview is the text that is displayed, and when it moves to the left, its font size slowly becomes larger, the transparency becomes clearer, and the text is eventually hidden when it slides to the right. The second child has a linearlayout and it is transparent, because when the view moves it is its child view, if you do not addLinearLayout So the entire layout slides to the left and doesn't se

Like click (clicks) is the core of the GUI platform, taps is the core of the touch platform, gesture (gestures) is the core of the Kinect application. Unlike digital interactions in a graphical user interface, gestures are a real-life activity. Without a computer we don't need a mouse, but without the Kinect, gestures still exist. Gestures, on the other hand, are part of the interaction between people in everyday life. Gestures can enhance the persuas
