Because the sliding effect of the page is used more throughout the application, all extracted into the parent class to introduce, see the code commentImport Android.app.activity;import Android.content.sharedpreferences;import Android.os.bundle;import Android.view.gesturedetector;import Android.view.motionevent;import Android.view.view;import Android.view.gesturedetector.simpleongesturelistener;import android.widget.toast;//defines an abstract method Shownext, which is implemented by the base cla

in the mobile browser The page is often scaled in use, and the scaled element coordinates change? The answer is somewhat different. Use a scenario to illustrate the problem: After page A is loaded, JavaScript obtains the coordinates of the element in document (100,100), and then the user enlarges the page, and then outputs the coordinate of the element again with JavaScript, still (100,100), However, the element's response area on the

Added to the view that needs to be recognized. Each gesture corresponds to only one view, and when the screen touches within the bounds of the view, if the gesture is the same as the reservation, the callback method is used. (iv), panning gest
