Android: enter或tab键仍将值输入到使用jetpack组合的密码输入字段中。

Question

当我输入或标签键仍然输入值到密码输入字段使用jetpack撰写。

下面是我的代码片段：

val (focusRequester) = FocusRequester.createRefs()

TextField(
    value = text,
    onValueChange = {
        text = it
    },
    singleLine = true,
    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
    keyboardActions = KeyboardActions(
        onDone = { focusRequester.requestFocus() }
    ),
    modifier = Modifier.onKeyEvent {
        if (it.nativeKeyEvent.keyCode == KeyEvent.KEYCODE_ENTER){
            focusRequester.requestFocus()
            true
        }
        false
    }
)

Tab key和enter key是通过Vysor键盘输入的，而不是来自安卓键盘。

这里欢迎任何建议。谢谢!

更新1:

有什么办法，我们可以做所有的功能键，如标准，而不使用下面的代码。

modifier = Modifier.onKeyEvent {
        if (it.nativeKeyEvent.keyCode == KeyEvent.KEYCODE_ENTER || it.nativeKeyEvent.keyCode == KeyEvent.KEYCODE_TAB) {
           focusManager.moveFocus(FocusDirection.Next)
      }
        false
    }

您可以使用regex，类似于：

 val pattern = remember { Regex("^[^\\t\\n]*\$") }
 val focusManager = LocalFocusManager.current

 TextField(
        value = text,
        onValueChange = {
            if (it.isEmpty() || it.matches(pattern)) {
                text = it
            }
        },
        singleLine = true,
        maxLines= 1,
                    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
        keyboardActions = KeyboardActions(
            onDone = { focusManager.moveFocus(FocusDirection.Next) }
        ),
        modifier = Modifier.onKeyEvent {
            if (it.nativeKeyEvent.keyCode == KeyEvent.KEYCODE_ENTER || it.nativeKeyEvent.keyCode == KeyEvent.KEYCODE_TAB) {
                focusManager.moveFocus(FocusDirection.Next)
            }
            false
        }
   )

我认为它应该有助于你清除焦点后，点击键盘完成按钮。

val focusManager = LocalFocusManager.current

TextField(
    value = text,
    onValueChange = {
       text = it
    },
    singleLine = true,
    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
    keyboardActions = KeyboardActions(
       onDone = { focusManager.clearFocus() }
    ),
)

val (focusRequester) = FocusRequester.createRefs()

TextField(
    value = text,
    onValueChange = {
            if (it.isEmpty() || it.matches(pattern)) {
                text = it
            }
        },
    singleLine = true,
    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
    keyboardActions = KeyboardActions(
        onDone = { focusRequester.requestFocus() }
    ),
    modifier = Modifier.onKeyEvent {
        if (it.nativeKeyEvent.keyCode == KeyEvent.KEYCODE_ENTER || it.nativeKeyEvent.keyCode == KeyEvent.KEYCODE_TAB) {
           focusManager.moveFocus(FocusDirection.Next)
      }
        false
    }
)
