AlertDialog被解除后，Edittext正在获得焦点并显示键盘

Question

我在片段和AlertDialog中有一个EditText。我正在使用EditText，然后单击"完成"按钮。但每当我关闭AlertDialog时，Edittext就会获得焦点并显示键盘。我不想在AlertDialog关闭后显示键盘。我该如何解决此问题？

我在解除AlertDialog后使用了val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager imm.hideSoftInputFromWindow(view.windowToken, 0)，但它不起作用。

Answer 1

create Extensions.kt

fun Activity.hideKeyboard(event: MotionEvent) {
if (event.action == MotionEvent.ACTION_DOWN) {
val view = currentFocus
if (view != null) {
view.clearFocus()
val inputMethodManager =
getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.hideSoftInputFromWindow(
view.windowToken,
InputMethodManager.HIDE_NOT_ALWAYS
)
}
}
}

您将使用的活动

override fun dispatchTouchEvent(event: MotionEvent): Boolean {
hideKeyboard(event)
return super.dispatchTouchEvent(event)
}

扩展。通过这种方式创建kt，您可以在任何需要的活动中使用它。扩展。删除除库和此写入代码之外的kt

Answer 2

试试这个：

fun showKeyboard(view: View) = ViewCompat.getWindowInsetsController(view)?.show(WindowInsetsCompat.Type.ime())
showKeyboard(binding.root)    //<- the root View of your dialog
