关闭软键盘

1.Fragment中关闭

fun Fragment.hiddenKeyboard(v : View){
    val imm = context?.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(v.getWindowToken(), 0)
}

　　给Fragment扩展一个函数，其中v是有焦点的 EditText

 

2.Activity中关闭

fun Activity.hiddenKeyboard(){
    val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(getWindow()?.getDecorView()?.getWindowToken(), 0/*InputMethodManager.HIDE_NOT_ALWAYS*/)
}
