[Android] [Kotlin] EditText 자동 포커싱 및 키보드

대상이 되는 EditText

<EditText>
    <requestFocus/>
</EditText>

 

포커싱 및 키보드 등장

private fun EditText.setFocusAndShowKeyboard(context: Context) {
    this.requestFocus()
    setSelection(this.text.length)
    this.postDelayed({
        val inputMethodManager =
            context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        inputMethodManager.showSoftInput(this, InputMethodManager.SHOW_FORCED)
    }, 100)
}

 

포커싱 해제 및 키보드 숨기기

private fun EditText.clearFocusAndHideKeyboard(context: Context) {
    this.clearFocus()
    this.postDelayed({
        val inputMethodManager =
            context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        inputMethodManager.hideSoftInputFromWindow(this.windowToken, 0)
    }, 30)
}
