1. Trigger the motionevent (ME) event when your finger touches the screen!
ME: This class is used to encapsulate action events such as gestures, touch pens, trackball, and so on.
It internally encapsulates two important attributes X and Y, which are used to record the coordinates of the horizontal and vertical axes, respectively.
2. The event is ontouchlistener monitored and the Motionevent object can be obtained in its Ontouch () Method!
3. Forwarding Motionevent objects to Ongestur
When I first started learning Android, I felt that Google's documents were not good, and when we studied gestures, I felt that Google's documents were too poor. A lot of constants, properties, and methods don't even have a description.There is no description, but there are so many gestures in ongesturelistener, it does not have a description, who can understand onlongpress and onshowpress before they try.Is there a difference between onscroll and onfling?

As I admire the "ages from," the same as the return. --It is estimated that the Wang Zixian was finished watching the night, and the spirits were gone, and went home.Gossip is seldom mentioned.When Tslib, there were ma
What is the HTML5 touch screen version?with the latest HTML5 technology, you can access the adaptive screen-size access interface and scan access without downloading the installation, downloading upgrades, and using the mobile browser.Why is there a PC Web version and a mobile app version that also requires HTML5 touch-screen version?First, the PC Web version is based on the traditional PC browser use, the mobile browser will appear on the screen size scaling, not suitable for use in mobile term

3. Modify SMPlayer File
In a friendly root file system, the SMPlayer script in the/user/lical/smplayer/bin directory is problematic, and if you run it directly, there will be situations where the mouse and touchscreen are not available, and we will copy the SMPlayer script from the/bin directory. and remove the QWS from the last t

Separating the creation of a complex object from its representation allows the same build process to create different representations.

familiarity. Users have been working on the same desktop environment for more than 10 years, and they don't want to move to a more touchscreen-based platform like Windows 8. So, which version would you choose? The first thing you have to consider is the desktop environment. Why? Because this is where you can instantly draw on these Windows 7 users. What version would be better for this task than Zorinos?Zorinos is specifically designed as a replaceme
