Custom View constructor in Android 4.4 crashes on Kotlin, how to fix? -


i have custom view written in kotlin using jvmoverloads have default value.

class myview @jvmoverloads constructor(     context: context,     attrs: attributeset? = null,     defstyle: int = 0,     defstyleres: int = 0 ) : linearlayout(context, attrs, defstyle, defstyleres)

all works fine in android 5.1 , above.

however crashes in 4.4, since constructor in 4.4 doesn't have defstyleres. how have supported in 5.1 , above have defstyleres not in 4.4, without need explicitly having 4 constructors defined did in java?

note: below works fine in 4.4, loose defstyleres.

class myview @jvmoverloads constructor(     context: context,     attrs: attributeset? = null,     defstyle: int = 0 ) : linearlayout(context, attrs, defstyle)

best way have class way.

class myview : linearlayout {     @jvmoverloads constructor(context: context, attrs: attributeset? = null, defstyleattr: int = 0) : super(context, attrs, defstyleattr)     @targetapi(build.version_codes.lollipop) constructor(context: context, attrs: attributeset?, defstyleattr: int, defstyleres: int) : super(context, attrs, defstyleattr, defstyleres) }

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 ...
