很简单,只需复制所有TextField
或OutlinedTextField
函数并删除defaultMinSize
,然后添加contentPadding
之后,您可以使用它来替代主要的TextField
或OutlinedTextField
对于OutlinedTextField
:
@Composable
fun BorderTextField(
value: String,
onValueChange: (String) -> Unit,
modifier: Modifier = Modifier,
enabled: Boolean = true,
readOnly: Boolean = false,
textStyle: TextStyle = LocalTextStyle.current,
label: @Composable (() -> Unit)? = null,
placeholder: @Composable (() -> Unit)? = null,
leadingIcon: @Composable (() -> Unit)? = null,
trailingIcon: @Composable (() -> Unit)? = null,
isError: Boolean = false,
visualTransformation: VisualTransformation = VisualTransformation.None,
keyboardOptions: KeyboardOptions = KeyboardOptions.Default,
keyboardActions: KeyboardActions = KeyboardActions.Default,
singleLine: Boolean = false,
maxLines: Int = Int.MAX_VALUE,
interactionSource: MutableInteractionSource = remember { MutableInteractionSource() },
shape: Shape = MaterialTheme.shapes.small,
colors: TextFieldColors = TextFieldDefaults.outlinedTextFieldColors()
) {
val textColor = textStyle.color.takeOrElse {
colors.textColor(enabled).value
}
val mergedTextStyle = textStyle.merge(TextStyle(color = textColor))
@OptIn(ExperimentalMaterialApi::class)
BasicTextField(
value = value,
modifier = if (label != null) {
modifier
.semantics(mergeDescendants = true) {}
} else {
modifier
}
.background(colors.backgroundColor(enabled).value, shape),
onValueChange = onValueChange,
enabled = enabled,
readOnly = readOnly,
textStyle = mergedTextStyle,
cursorBrush = SolidColor(colors.cursorColor(isError).value),
visualTransformation = visualTransformation,
keyboardOptions = keyboardOptions,
keyboardActions = keyboardActions,
interactionSource = interactionSource,
singleLine = singleLine,
maxLines = maxLines,
decorationBox = @Composable { innerTextField ->
TextFieldDefaults.OutlinedTextFieldDecorationBox(
value = value,
visualTransformation = visualTransformation,
innerTextField = innerTextField,
placeholder = placeholder,
label = label,
leadingIcon = leadingIcon,
trailingIcon = trailingIcon,
singleLine = singleLine,
enabled = enabled,
isError = isError,
interactionSource = interactionSource,
colors = colors,
contentPadding = TextFieldDefaults.outlinedTextFieldPadding(
start = 0.dp,
top = 0.dp,
end = 0.dp,
bottom = 0.dp
),
border = {
TextFieldDefaults.BorderBox(
enabled,
isError,
interactionSource,
colors,
shape
)
}
)
}
)
}
BasicTextField
添加一个trailingIcon
,该怎么办? - kc_devTextFieldDefaults.TextFieldDecorationBox
作为decorationBox
参数传递,其中包含leadingIcon
和trailingIcon
参数。 - Eyjafl
