Android compose OutlinedTextField 输入框设置固定高度后，内容挤压显示不全

原因：

decorationBox里边contentPadding() 默认为16.dp

internal val TextFieldPadding = 16.dp

修改方法1：

copy OutlinedTextField.kt 源码，decorationBox的contentPadding参数开放出来

/*** @author   创建人：蒙石瑞* @date     创建时间：2024/8/7 09:54* @Description    创建内容：(这里用一句话描述这个类的作用)*/internal val OutlinedTextFieldTopPadding = 8.dp@OptIn(ExperimentalMaterial3Api::class)

}

方法二：基于

BasicTextField 自定义

OutlinedTextFieldDefaults.DecorationBox

//            BasicTextField(
//                value = text,
//                onValueChange = { text = it },
//                modifier = Modifier
//                    .height(36.dp),
//                singleLine = true,
//            ) { innerTextField ->
//                OutlinedTextFieldDefaults.DecorationBox(
//                    value = text,
//                    innerTextField = innerTextField,
//                    enabled = true,
//                    singleLine = true,
//                    label = { Text("工号", modifier = Modifier.padding(0.dp)) },
//                    visualTransformation = VisualTransformation.None,
//                    interactionSource = interactionSource,
//                    contentPadding = TextFieldDefaults.textFieldWithoutLabelPadding(
//                        top = 0.dp,
//                        bottom = 0.dp
//                    )
//                )
//            }
