关闭软键盘

1.Fragment中关闭

1 fun Fragment.hiddenKeyboard(v : View){
2     val imm = context?.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
3     imm.hideSoftInputFromWindow(v.getWindowToken(), 0)
4 }

　　给Fragment扩展一个函数，其中v是有焦点的 EditText

 

2.Activity中关闭

1 fun Activity.hiddenKeyboard(){
2     val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
3     imm.hideSoftInputFromWindow(getWindow()?.getDecorView()?.getWindowToken(), 0/*InputMethodManager.HIDE_NOT_ALWAYS*/)
4 }
