Dismiss keyboard when click outside of EditText in android

Question

I have an EditText called myTextview. I want the soft keyboard to show when I click on the EditText but then dismiss if I click outside of

Answer 1

Touch event on a View will start with ACTION_DOWN from being passed from top to this View in view hierachy. Override dispatchTouchEvent to do additional things. Here's an example to extend from FrameLayout in kotlin:

class TLayout @JvmOverloads constructor(context: Context, attrs: AttributeSet?=null):
        FrameLayout(context, attrs){

    var preDispatchTouchEvent: ((ev: MotionEvent?)->Boolean)? = null

    override fun dispatchTouchEvent(ev: MotionEvent?): Boolean {
        if (preDispatchTouchEvent==null || !preDispatchTouchEvent!!.invoke(ev)) {
            super.dispatchTouchEvent(ev)
        }
        return true
    }

}

Wrap your EditText and other relative Views under this layout, and set preDispatchTouchEvent to dismiss EditText when event is not above it.
