How to do generic onTouchEvent method for kotlin?
I have such a method. In loginactivity.kt. What I want to do is make this method generic and use it everywhere. I want to write a method in CommonExtensions.kt, but I can't write it right and I get an error. How can I make Generic become
LoginActivity.kt
override fun onTouchEvent(event: MotionEvent?): Boolean {
val imm = this.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(this.currentFocus?.windowToken, 0)
return super.onTouchEvent(event)
}
CommonExtensions.kt
fun Context.onTouchEvent(event: MotionEvent?): Boolean {
val imm = this.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(this.onTouchEvent()?.windowToken, 0)
}

You have a couple of options:
- Create a basic class for Activities, for example
BaseActivityand overrideonTouchEventmethod there. Inherit from that activity other activities.
Create some util file, for example
UiUtils.ktand define method of hiding keyboard there, e.g.:
fun hideKeyboard(view: View) {
val imm = view.context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(view.windowToken, 0)
}
Call it from your activities'
onTouchEvent()method:
override fun onTouchEvent(event: MotionEvent?): Boolean {
hideKeyboard(someView)
return super.onTouchEvent(event)
}
Create extension function on
Viewin yourCommonExtensions.ktfile:
fun View.hideKeyboard() {
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(windowToken, 0)
}
And call it from
onTouchEvent()method:
override fun onTouchEvent(event: MotionEvent?): Boolean {
someView.hideKeyboard()
return super.onTouchEvent(event)
}
