《伴时匣》app开发技术分享--表单提交准备（4）
## 技术栈
Appgallery connect
## 开发准备
上一节我们实现了用户登录功能，现在我们进入首页，可以开始准备着手发布我们的日期计划了，在这之前我们先实现信息表的创建。在首页实现一个标题栏，一个悬浮的按钮。
## 功能分析
我们的信息表要展示的内容很多，首先是我们的事件名称，目标日期选择，公历农历，正数倒数，倒数类目的选择，是否实现置顶效果，是否显示精确时间，事件颜色，事件图标，事件心情，事件天气，跟用户绑定，跟绑定的关系用户绑定等。
## 功能开发
我们先实现对应的表的创建
```c
{
"objectTypeName": "push_table_day",
"fields": [
{"fieldName": "id", "fieldType": "Integer", "notNull": true, "belongPrimaryKey": true},
{"fieldName": "user_id", "fieldType": "Integer", "notNull": true, "defaultValue": 0},
{"fieldName": "title", "fieldType": "String"},
{"fieldName": "day", "fieldType": "String"},
{"fieldName": "time_type", "fieldType": "Integer"},
{"fieldName": "menu_id", "fieldType": "Integer"},
{"fieldName": "is_show_top", "fieldType": "Boolean"},
{"fieldName": "is_show_time", "fieldType": "Boolean"},
{"fieldName": "tab_color_id", "fieldType": "Integer"},
{"fieldName": "tab_icon_id", "fieldType": "Integer"},
{"fieldName": "tab_mood_id", "fieldType": "Integer"},
{"fieldName": "tab_weather_id", "fieldType": "Integer"},
{"fieldName": "bind_user_id", "fieldType": "Integer"},
{"fieldName": "bind_type", "fieldType": "Integer"},
{"fieldName": "table_message_id", "fieldType": "Integer"}
],
"indexes": [
{"indexName": "field1Index", "indexList": [{"fieldName":"id","sortType":"ASC"}]}
],
"permissions": [
{"role": "World", "rights": ["Read", "Upsert", "Delete"]},
{"role": "Authenticated", "rights": ["Read", "Upsert", "Delete"]},
{"role": "Creator", "rights": ["Read", "Upsert", "Delete"]},
{"role": "Administrator", "rights": ["Read", "Upsert", "Delete"]}
]
}
```
db类
```c
import { cloudDatabase } from '@kit.CloudFoundationKit';
class push_table_day extends cloudDatabase.DatabaseObject {
public id: number;
public user_id = 0;
public title: string;
public day: string;
public time_type: number;
public menu_id: number;
public is_show_top: boolean;
public is_show_time: boolean;
public tab_color_id: number;
public tab_icon_id: number;
public tab_mood_id: number;
public tab_weather_id: number;
public bind_user_id: number;
public bind_type: number;
public table_message_id: number;
public naturalbase_ClassName(): string {
return 'push_table_day';
}
}
export { push_table_day };
```
实体类
```c
class PushTableDay {
id: number;
user_id: number = 0;
title: string;
day: string;
time_type: number;
menu_id: number;
is_show_top: boolean;
is_show_time: boolean;
tab_color_id: number;
tab_icon_id: number;
tab_mood_id: number;
tab_weather_id: number;
bind_user_id: number;
bind_type: number;
table_message_id: number;
constructor() {
}
setId(id: number): void {
this.id = id;
}
getId(): number {
return this.id;
}
setUser_id(user_id: number): void {
this.user_id = user_id;
}
getUser_id(): number {
return this.user_id;
}
setTitle(title: string): void {
this.title = title;
}
getTitle(): string {
return this.title;
}
setDay(day: string): void {
this.day = day;
}
getDay(): string {
return this.day;
}
setTime_type(time_type: number): void {
this.time_type = time_type;
}
getTime_type(): number {
return this.time_type;
}
setMenu_id(menu_id: number): void {
this.menu_id = menu_id;
}
getMenu_id(): number {
return this.menu_id;
}
setIs_show_top(is_show_top: boolean): void {
this.is_show_top = is_show_top;
}
getIs_show_top(): boolean {
return this.is_show_top;
}
setIs_show_time(is_show_time: boolean): void {
this.is_show_time = is_show_time;
}
getIs_show_time(): boolean {
return this.is_show_time;
}
setTab_color_id(tab_color_id: number): void {
this.tab_color_id = tab_color_id;
}
getTab_color_id(): number {
return this.tab_color_id;
}
setTab_icon_id(tab_icon_id: number): void {
this.tab_icon_id = tab_icon_id;
}
getTab_icon_id(): number {
return this.tab_icon_id;
}
setTab_mood_id(tab_mood_id: number): void {
this.tab_mood_id = tab_mood_id;
}
getTab_mood_id(): number {
return this.tab_mood_id;
}
setTab_weather_id(tab_weather_id: number): void {
this.tab_weather_id = tab_weather_id;
}
getTab_weather_id(): number {
return this.tab_weather_id;
}
setBind_user_id(bind_user_id: number): void {
this.bind_user_id = bind_user_id;
}
getBind_user_id(): number {
return this.bind_user_id;
}
setBind_type(bind_type: number): void {
this.bind_type = bind_type;
}
getBind_type(): number {
return this.bind_type;
}
setTable_message_id(table_message_id: number): void {
this.table_message_id = table_message_id;
}
getTable_message_id(): number {
return this.table_message_id;
}
}
export { PushTableDay };
```
我们实现首页标题栏和悬浮添加按钮
```c
import { CommonTopBar } from './widget/CommonTopBar'
@Entry
@Component
struct Index {
build() {
Column(){
CommonTopBar({ title: "主页", alpha: 0, titleAlignment: TextAlign.Center ,backButton:false})
Stack({alignContent:Alignment.BottomEnd}){
Column(){
List(){
}
}
.height('100')
.width('100%')
Text("+")
.fontSize(38)
.width(60)
.textAlign(TextAlign.Center)
.backgroundColor("#ff65c8ee")
.fontWeight(FontWeight.Bold)
.fontColor(Color.Black)
.height(60)
.borderRadius(30)
.margin({bottom:80,right:40})
}
.height('100%')
.width('100%')
}
.height('100%')
.width('100%')
.backgroundColor(Color.White)
}
}
```
这样我们就完成了表单的创建和标题栏悬浮按钮的实现
