如何从 jetpack compose 更改 OutlinedTextField 的轮廓颜色？

Question

这是 OutlinedTextField 代码在 jetpack-compose 中的样子：

OutlinedTextField(
    value = "",
    onValueChange = {},
    label = {Text("Input")}
)

此 TextField 轮廓的默认颜色是紫色。我想明显地改变轮廓颜色和标签。

Answer 1

OutlinedTextField

使用的默认值由 TextFieldDefaults.outlinedTextFieldColors

、

focusedBorderColor、

unfocusedBorderColor

在 disabledBorderColor 中定义。

与 M2:

focusedBorderColor: Color = MaterialTheme.colors.primary.copy(alpha = ContentAlpha.high),
unfocusedBorderColor: Color = MaterialTheme.colors.onSurface.copy(alpha = ContentAlpha.disabled),

您可以更改主题中的

colors.primary

和

colors.onSurface

。

与 M3:

    focusedBorderColor: Color = OutlinedTextFieldTokens.FocusOutlineColor.toColor(),
    unfocusedBorderColor: Color = OutlinedTextFieldTokens.OutlineColor.toColor(),

在这种情况下，您可以更改主题中的

primary

和

outline

颜色。

否则你可以使用以下方法覆盖它们：

    OutlinedTextField(
        value = "",
        onValueChange = {},
        label = {Text("Input")},
        colors = TextFieldDefaults.outlinedTextFieldColors(
            focusedBorderColor = Green,
            unfocusedBorderColor = Yellow)
    )

@Preview
@Composable
fun TelephoneEditText() {
    val textValue = remember {
        mutableStateOf("")
    }

    OutlinedTextField(
        label = {
            Text(
                text = stringResource(
                    id = R.string.phoneNumber
                ),
                style = TextStyle(
                    color = MaterialTheme.colors.primaryVariant,
                )
            )
        },
        placeholder = {
            Text(
                text = stringResource(id = R.string.phone_placeholder),
                style = TextStyle(
                    color = MaterialTheme.colors.primaryVariant,
                    textAlign = TextAlign.Center
                )
            )
        },
        colors = TextFieldDefaults.outlinedTextFieldColors(
            focusedBorderColor = MaterialTheme.colors.secondary,
            unfocusedBorderColor = MaterialTheme.colors.secondary,
            focusedLabelColor = MaterialTheme.colors.secondary,
            cursorColor = MaterialTheme.colors.primaryVariant
        ),
        keyboardOptions = KeyboardOptions.Default.copy(keyboardType = KeyboardType.Number),
        value = textValue.value,
        onValueChange = { textValue.value = it },
    )
    WhatsAppButton(textValue)
}

val Yellow500 = Color(0XFFFFDE03)
val Blue700 = Color(0xFF0036FF)
val Pink500 = Color(0xFFf50057)
val Pink700 = Color(0xFFff5983)

val LightColors = lightColors(
    primary = Yellow500,
    primaryVariant = Blue700,
    secondary = Pink500,
    secondaryVariant = Pink700

val DarkColors = darkColors(
    primary = Yellow500,
    primaryVariant = Blue700,
    secondary = Pink700
)

对于 1.0.0 beta-1

OutlinedTextField(
    value = "",
    onValueChange = {},
    label = {Text("Input")},
    color = TextFieldDefaults.outlinedTextFieldColors(
            focusedBorderColor: Color = MaterialTheme.colors.primary.copy(alpha = 
              ContentAlpha.high),
            unfocusedBorderColor: Color = MaterialTheme.colors.onSurface.copy(alpha = 
              ContentAlpha.disabled),
            disabledBorderColor: Color = unfocusedBorderColor.copy(alpha =
              ContentAlpha.disabled),
            errorBorderColor: Color = MaterialTheme.colors.error,
    )
)

使用上述参数根据情况设置边框颜色。

Answer 4

使用撰写 androidx.compose:compose-bom:2023.04.01 现在你需要使用颜色。 对于背景，使用容器颜色，对于边框，使用指示符颜色

  OutlinedTextField(
            searchValue.value,
            {
                searchValue.value = it
            },
            placeholder = { Text(text = stringResource(id = R.string.hint_search_food)) },
            keyboardOptions = KeyboardOptions(
                keyboardType = KeyboardType.Text, imeAction = ImeAction.Search
            ),
            modifier = Modifier.fillMaxWidth(),
            shape = RoundedCornerShape(24.dp),
            colors = TextFieldDefaults.colors(
                unfocusedContainerColor = fieldBackGroundColor,
                focusedContainerColor = fieldBackGroundColor,
                focusedIndicatorColor = fieldBackGroundColor,
                unfocusedIndicatorColor = fieldBackGroundColor
            ),
            leadingIcon = {
                Icon(Icons.Outlined.Search, "Search")
            },
        )

Answer 5

我相信这是 M3 的解决方案：

colors = TextFieldDefaults.textFieldColors(
                backgroundColor = Color.Transparent,
                cursorColor = androidx.compose.material3.MaterialTheme.colorScheme.onPrimaryContainer.copy(alpha = ContentAlpha.medium),
                focusedIndicatorColor = androidx.compose.material3.MaterialTheme.colorScheme.onPrimaryContainer.copy(alpha = ContentAlpha.medium),
                focusedLabelColor = androidx.compose.material3.MaterialTheme.colorScheme.onPrimaryContainer.copy(alpha = ContentAlpha.medium)
            )

Answer 6

您可以使用此属性来更改边框颜色

OutlinedTextFieldDefaults.colors(
                    focusedBorderColor = // someColor,
                    unfocusedBorderColor = //someColor,
                )

例如，

OutlinedTextField(
                value = status,
                onValueChange = { status = it },
                shape = RoundedCornerShape(8.dp),
                colors = OutlinedTextFieldDefaults.colors(
                    focusedBorderColor = Grey80,
                    unfocusedBorderColor = Grey80,
                )

            )

您有很多选择可供尝试。

Answer 7

在 Compose 1.4.0 和 Material 3 中，您可以使用以下内容：

    OutlinedTextField(
        value = "Hello",
        onValueChange = {},
        colors = TextFieldDefaults.outlinedTextFieldColors(
            containerColor =,
            focusedBorderColor =,
            unfocusedBorderColor =
        ),
    )
