Jetpack compose basic textfield no cursor

问题

I'll provide the translated code portion without the comments:

原谅我如果我现在问了一个非常愚蠢的问题，但我对Compose还很新。我试图创建一个类似我想要的BasicTextField，但由于某种原因，当我选择了TextField并且键盘显示时，光标不会闪烁。我在普通的TextField中看到了它，但我不喜欢默认的外观。我是不是漏掉了某一行或某些内容？谢谢

Forgive if I ask something really stupid now but I'm quite new to compose. I'm trying to create a BasicTextField which looks like I want it to but for some reason there is no cursor blinking when I've selected the TextField and the keyboard is showing. I saw it with a normal TextField but I didn't like the looks of the default things. Am I missing a line or something? Thanks

fun CustomSearchField(state: MutableState&lt;TextFieldValue&gt;) {
val focusManager = LocalFocusManager.current
val keyboardController = LocalSoftwareKeyboardController.current
BasicTextField(
value = state.value,
onValueChange = { value -&gt;
state.value = value
},
singleLine = true,
cursorBrush = SolidColor(Color.White),
keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
keyboardActions = KeyboardActions(
onDone = {
keyboardController?.hide()
focusManager.clearFocus()
}
),
decorationBox = {
Row(
horizontalArrangement = Arrangement.spacedBy(8.dp),
verticalAlignment = Alignment.CenterVertically,
modifier = Modifier
.padding(horizontal = 16.dp)
.fillMaxWidth()
.heightIn(48.dp)
.clip(shape = RoundedCornerShape(8.dp))
.border(
BorderStroke(
1.dp, colorResource(R.color.cardBorder)
), shape = RoundedCornerShape(8.dp)
)
) {
Image(
painter = painterResource(id = R.drawable.ic_search_icon),
contentDescription = null,
contentScale = ContentScale.Crop,
colorFilter = ColorFilter.tint(colorResource(if (state.value == TextFieldValue(&quot;&quot;)) R.color.mainGray else R.color.primaryTextColor)),
modifier = Modifier
.padding(start = 16.dp)
.size(24.dp)

白色刷子颜色可能是问题的原因。

cursorBrush = SolidColor(Color.White)
英文:

White brush color might be the culprit here.

cursorBrush = SolidColor(Color.White)

  1. 光标颜色是白色：
cursorBrush = SolidColor(Color.Black),
  1. decorationBox 接受一个带有文本框和文本控件的参数。在 decorationBox 函数中，你需要添加 innerTextField -> 以指定该参数的名称。然后，在行内，你需要调用这个组合。
decorationBox = {
    Row(
        horizontalArrangement = Arrangement.spacedBy(8.dp),
        verticalAlignment = Alignment.CenterVertically,
        modifier = Modifier
            .padding(horizontal = 16.dp)
            .fillMaxWidth()
            .heightIn(48.dp)
            .clip(shape = RoundedCornerShape(8.dp))
            .border(
                BorderStroke(
                    1.dp, colorResource(R.color.cardBorder)
                ), shape = RoundedCornerShape(8.dp)
            )
    ) {
        Image(
            painter = painterResource(id = R.drawable.ic_search_icon),
            contentDescription = null,
            contentScale = ContentScale.Crop,
            colorFilter = ColorFilter.tint(colorResource(if (state.value == TextFieldValue("")) R.color.mainGray else R.color.primaryTextColor)),
            modifier = Modifier
                .padding(start = 16.dp)
                .size(24.dp)
        )
    
        if (state.value == TextFieldValue("")) {
            /*Text(
                text = "Search",
                style = poppinsRegular(14),
                color = colorResource(id = R.color.mainGray),
                modifier = Modifier
                    .weight(1f)
            )*/
        } else {
            innerTextField() // <--- 在这里
        }
    
        if (state.value != TextFieldValue("")) {
            IconButton(
                onClick = {
                    state.value =
                        TextFieldValue("")
                }
            ) {
                Image(
                    painter = painterResource(id = R.drawable.clear_icon),
                    contentDescription = null,
                    contentScale = ContentScale.Crop,
                    colorFilter = ColorFilter.tint(colorResource(R.color.primaryTextColor)),
                    modifier = Modifier
                        .size(24.dp)
                        .padding(2.dp)
                )
            }
        }
    }
}
英文:

There are two issues:

  1. The cursor color is white:
cursorBrush = SolidColor(Color.Black),
  1. decorationBox takes an argument with the text box and text controls. At the decorationBox function, you need to add innerTextField -&gt; to make that the argument name. Then, inside the row, you need to call the composable.

decorationBox = {
Row(
horizontalArrangement = Arrangement.spacedBy(8.dp),
verticalAlignment = Alignment.CenterVertically,
modifier = Modifier
.padding(horizontal = 16.dp)
.fillMaxWidth()
.heightIn(48.dp)
.clip(shape = RoundedCornerShape(8.dp))
.border(
BorderStroke(
1.dp, colorResource(R.color.cardBorder)
), shape = RoundedCornerShape(8.dp)
)
) {
Image(
painter = painterResource(id = R.drawable.ic_search_icon),
contentDescription = null,
contentScale = ContentScale.Crop,
colorFilter = ColorFilter.tint(colorResource(if (state.value == TextFieldValue(&quot;&quot;)) R.color.mainGray else R.color.primaryTextColor)),
modifier = Modifier
.padding(start = 16.dp)
.size(24.dp)
)
if (state.value == TextFieldValue(&quot;&quot;)) {
/*Text(
text = &quot;Search&quot;,
style = poppinsRegular(14),
color = colorResource(id = R.color.mainGray),
modifier = Modifier
.weight(1f)
)*/
} else {
innerTextField() // &lt;--- HERE
}
if (state.value != TextFieldValue(&quot;&quot;)) {
IconButton(
onClick = {
state.value =
TextFieldValue(&quot;&quot;)
}
) {
Image(
painter = painterResource(id = R.drawable.clear_icon),
contentDescription = null,
contentScale = ContentScale.Crop,
colorFilter = ColorFilter.tint(colorResource(R.color.primaryTextColor)),
modifier = Modifier
.size(24.dp)
.padding(2.dp)
)
}
}
}
}
