问题 I have a ViewPager below a NestedScrollView width some top padding, and clipToPadding(false) and transparent background (like as image). My ViewPager can't get touch event and doesn't work.

问题 How can I implement a custom onInterceptTouchEvent() in a ListView that give the scrolling priority to the child's of the ListView and as soon as they did their scrolling , give it back to the ListView ? I want to give priority to the inner views. 回答1: Try overriding onInterceptTouchEvent() of your children like this: @Override public boolean onInterceptTouchEvent(MotionEvent ev) { if(!isAtTop && !isAtBottom){ getParent().requestDisallowInterceptTouchEvent(true); } return super

问题 Is it possible for a background process or softkeyboard to create touch events and send them to screen as if the screen was actually touched? i.e. simulating touch screen events. 回答1: There is a tool that comes with the SDK called Monkey which generates pseudo-random streams of user events such as: clicks touches gestures a number of system-level events. You can use the Monkey to stress-test applications that you are developing, in a random yet repeatable manner. There is also the

问题 I have a subclass of UIView on top of a UITableView . I am using the UITableView to display some data and, at the same time, I would like to overlay an animation that follows the finger (for instance, leaving a trail). If I get it right, I need the touch events to be handled both by the UIView subclass and the UITableView . How can I do that? Is it possible to have, ie, touchesMoved being triggered on the UIView subclass and then on UITableView ? Thank you so much for any help. 回答1: The way I

问题 I have a top level ViewGroup, which I call SliderView, in which I want to detect swiping. This is mostly working, but one weird failure persists. The essence of SliderView is to override onInterceptTouchEvent and, once the user is actually swiping, return "true" to prevent other views from seing the MotionEvent. Here is a snip of code: public class SliderView extends ViewGroup { enum MoveState { MS_NONE, MS_HSCROLL, MS_VSCROLL }; private MoveState moveState = MoveState.MS_NONE; ... other code

问题 Using myObject.performClick() I can simulate click event from the code. Does something like this exist for onTouch event? Can I mimic touch action from the Java code? EDIT This is my onTouch listener. myObject.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View view, MotionEvent motionEvent) { // do something return false; } }); 回答1: This should work, found here: How to simulate a touch event in Android?: // Obtain MotionEvent object long downTime =
