Android JetPack组成：浏览文本字段

发布于 2025-02-01 17:08:15 字数 599 浏览 4 评论 0原文

我实现了一个具有很多文本场的屏幕，并将脚手架用作根层。因为我希望我的屏幕是RTL，所以我使用了构图本地提供商（）。

CompositionLocalProvider(LocalLayoutDirection provides LayoutDirection.Rtl ) {}

我的文本场在屏幕上像这样：

，当我想浏览这些Textfields时：

keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next),
keyboardActions = KeyboardActions(
      onNext = { LocalFocusManager.current.moveFocus(FocusDirection.Next) }
)

我希望发生的事情：a - ＆gt; b - ＆gt; c - ＆gt; D

发生了什么：b - ＆gt; a - ＆gt; D - ＆GT; c

（我为父词使用了一个列，但文本字段的行作为父根二乘两个（排在列中））

有人可以帮忙吗？谢谢。

I implemented a screen that has a lot of TextFields and I used the scaffold as a root layer.
Because I wanted my screen to be rtl, I used Composition Local provider().

CompositionLocalProvider(LocalLayoutDirection provides LayoutDirection.Rtl ) {}

My TextFields were on the screen like this:

B A

D C

and when I wanted to navigate through these TextFields:

keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next),
keyboardActions = KeyboardActions(
      onNext = { LocalFocusManager.current.moveFocus(FocusDirection.Next) }
)

what I Expected to happend: A -> B -> C -> D

what happend: B -> A -> D -> C

(I used a Column for parent root but textfields have Row as Parent root two by two (the Rows are in Column))

Can anyone help?
Thanks.

您可以使用.focusorder修饰符来实现这一目标：

Column() {
    val (aFocus, bFocus, cFocus, dFocus) = remember { FocusRequester.createRefs() }


    Row {
        OutlinedTextField(
            value = "A",
            onValueChange = {},
            modifier = Modifier
                .weight(1f)
                .focusOrder(aFocus) { next = bFocus },
            keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next),
        )
        OutlinedTextField(
            value = "B",
            onValueChange = {},
            modifier = Modifier
                .weight(1f)
                .focusOrder(bFocus) { next = cFocus },
            keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next)
        )
    }

    Row {
        OutlinedTextField(
            value = "C",
            onValueChange = {},
            modifier = Modifier
                .weight(1f)
                .focusOrder(cFocus) { next = dFocus },
            keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next)
        )
        OutlinedTextField(
            value = "D",
            onValueChange = {},
            modifier = Modifier
                .weight(1f)
                .focusOrder(dFocus) { },
            keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next)
        )
    }
}

You can use .focusOrder modifier to achieve this:

Column() {
    val (aFocus, bFocus, cFocus, dFocus) = remember { FocusRequester.createRefs() }


    Row {
        OutlinedTextField(
            value = "A",
            onValueChange = {},
            modifier = Modifier
                .weight(1f)
                .focusOrder(aFocus) { next = bFocus },
            keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next),
        )
        OutlinedTextField(
            value = "B",
            onValueChange = {},
            modifier = Modifier
                .weight(1f)
                .focusOrder(bFocus) { next = cFocus },
            keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next)
        )
    }

    Row {
        OutlinedTextField(
            value = "C",
            onValueChange = {},
            modifier = Modifier
                .weight(1f)
                .focusOrder(cFocus) { next = dFocus },
            keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next)
        )
        OutlinedTextField(
            value = "D",
            onValueChange = {},
            modifier = Modifier
                .weight(1f)
                .focusOrder(dFocus) { },
            keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next)
        )
    }
}
