Click not working on RecyclerView in CoordinatorLayout when scrolling

由 淺唱寂寞╮ 提交于 2019-11-29 01:20:03
问题 I am facing a strange behaviour with a RecyclerView as a second child of CoordinatorLayout, just after an AppBarLayout (as described in a lot of examples). My problem is when I scroll the recycler view and I want to click on a particular item. Sometimes I need to click 2 times to select that item, it seems to be linked to the fling behaviour. For example, if I scrolled to the bottom of the recycler view, then if I fling my finger from the bottom of the screen to the top (in order to see more

I tried to understand how Android handle touch event and got a little bit confused. From what I understand touch event are send to the root view and pass down to the children. I have a FrameLayout that is a container for Fragment . First fragment view is a ScrollView , second one is some kind of Gallery (HorizontalListView) and the last one is also FrameLayout . Only one fragment in the layout each time. What I want to do is to identify user swipes on the screen, for the app use. I want to count the swipes and do something after some number of swipes. I tried to put a OnTouchListener on the

Bind event to element using pure Javascript

问题 I'm writing an API and unfortunately need to avoid any jQuery or 3rd party libraries. How exactly are the events bound to elements through jQuery? jQuery example: $('#anchor').click(function(){ console.log('anchor'); }); I'm close to writing a onClick attribute on the element out of frustration, but I would like to understand the link between the jQuery event and DOM element. How exactly does the element know to fire a jQuery event when the markup itself is not changed? How are they catching

Running a batch script by right clicking any file

由 丶灬走出姿态 提交于 2019-11-28 21:40:56
The idea is to right click any file and then select "backup" in a drop down that just copies the file and adds a date time to the end of its name, then possibly moves that copy to another drive. I would like a method of running a batch script by right clicking on a file and either passing that in as an argument (without typing it in), or somehow knowing that file is the one that should be used in the script. Mainly for windows XP, I need it to be native as many site computers I work on do not belong to us and I don't want to copy over more files than necessary or rely on anything more than the

How do I clear the dropdownlist values on button click event using jQuery?

问题 How do I clear the dropdownlist values on button click event using jQuery? 回答1: A shorter alternative to the first solution given by Russ Cam would be: $('#mySelect').val(''); This assumes you want to retain the list, but make it so that no option is selected. If you wish to select a particular default value, just pass that value instead of an empty string. $('#mySelect').val('someDefaultValue'); or to do it by the index of the option, you could do: $('#mySelect option:eq(0)').attr('selected'
