event handling - Android child onTouchListener disabling parent onClick -


i have parent, custom relativelayout inflates 2 imageviews: 1 content image, , close button in top right corner.

the issue: cannot have both gestures/scaling of content image functioning , close button functioning.

the content image custom imageview subclass (a modification of https://github.com/mikeortiz/touchimageview), has it's own ontouchlistener allow pinch-zooming, , responding usual gestures. ontouchlistener contains code:

private class privateontouchlistener implements ontouchlistener {     @override     public boolean ontouch(view v, motionevent event) {         mscaledetector.ontouchevent(event);         mgesturedetector.ontouchevent(event);         //....         return true;

now, if return true, scaling/gestures content image works, close button onclick never called, whereas if it's false scaling/getures don't work , onclick can called.

i don't understand why return function called after event passed gesture detector affects (?consumes event) whether or not gesture detector works. there simple way of ensuring functionality of both child imageviews, return function false both detectors still work?

what i've tried:

  • ensuring methods in gesturedetector return false, event isn't consumed. (the scaledetector isn't custom, haven't done same there; if think that's problem let me know)

  • an onintercepttouch method in parent relativelayout, i'm not sure if implemented correctly

  • (reading around event handling understand how works)

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
