1.主界面选项卡搭建

从【鸿蒙】鸿蒙App应用-《记账软件》登录，注册，找回密码功能登录成功之后，进入主界面。

这里我们先搭建主界面的布局结构，首先完成五个模块的选项卡的界面显示。

在layout文件夹下新建xml布局文件，使用垂直的现形布局摆放，分为三部分，头部标题，内容部分，选项卡部分。

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayoutxmlns:ohos="http://schemas.huawei.com/res/ohos"ohos:height="match_parent"ohos:width="match_parent"ohos:orientation="vertical"><!-- 标题部分 --><Textohos:id="$+id:tt"ohos:height="match_content"ohos:width="match_parent"ohos:background_element="#FFDA44"ohos:padding="10fp"ohos:text="$string:app_name"ohos:text_alignment="center"ohos:text_color="#000"ohos:text_font="HwChinese-medium"ohos:text_size="25fp"ohos:text_weight="1200"/>
<!--    内容部分   --><StackLayoutohos:height="match_content"ohos:width="match_parent"ohos:background_element="#fff"ohos:weight="1"></StackLayout><!--分割线--><Textohos:height="1fp"ohos:width="match_parent"ohos:background_element="#000"/><!--选项卡部分--><DirectionalLayoutohos:id="$+id:tb_dl"ohos:height="match_content"ohos:width="match_parent"ohos:alignment="center"ohos:orientation="horizontal"><DirectionalLayoutohos:id="$+id:dl1"ohos:height="match_parent"ohos:width="match_content"ohos:alignment="center"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:image1"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:bottom_detail_pressed"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="明细"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout><DirectionalLayoutohos:id="$+id:dl2"ohos:height="match_parent"ohos:width="match_content"ohos:alignment="center"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:image2"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:bottom_chart_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="图表"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout><DirectionalLayoutohos:id="$+id:dl3"ohos:height="match_parent"ohos:width="match_content"ohos:alignment="center"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:image3"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:bottom_add_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="记账"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout><DirectionalLayoutohos:id="$+id:dl4"ohos:height="match_parent"ohos:width="match_content"ohos:alignment="center"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:image4"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:bottom_find_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="发现"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout><DirectionalLayoutohos:id="$+id:dl5"ohos:height="match_parent"ohos:width="match_content"ohos:alignment="center"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:image5"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:bottom_me_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="我的"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout></DirectionalLayout></DirectionalLayout>

2.给选项卡添加事件监听

在src文件的包中创建AbilitySlice类继承至BaseAbilitySlice基类。并定义好选项卡的切换图片资源。

public class MainAbilitySlice extends BaseAbilitySlice {//选项卡默认图标private int[] imgs_normal = {ResourceTable.Media_bottom_detail_normal,ResourceTable.Media_bottom_chart_normal,ResourceTable.Media_bottom_add_normal,ResourceTable.Media_bottom_find_normal,ResourceTable.Media_bottom_me_normal};//选项卡选中图标private int[] imgs_pressed = {ResourceTable.Media_bottom_detail_pressed,ResourceTable.Media_bottom_chart_pressed,ResourceTable.Media_bottom_add_normal,ResourceTable.Media_bottom_find_pressed,ResourceTable.Media_bottom_me_pressed};//获得选项卡对应的布局idprivate int[] dl_ids = {ResourceTable.Id_dl1,ResourceTable.Id_dl2,ResourceTable.Id_dl3,ResourceTable.Id_dl4,ResourceTable.Id_dl5};//获得选项卡的图片组件idprivate int[] image_ids = {ResourceTable.Id_image1,ResourceTable.Id_image2,ResourceTable.Id_image3,ResourceTable.Id_image4,ResourceTable.Id_image5};//初始化选项卡布局数组private DirectionalLayout[] dls = new DirectionalLayout[imgs_normal.length];//初始化选项卡图片组件数组private Image[] images = new Image[imgs_normal.length];//初始化选项卡的选中状态，默认第一个模块被选中private boolean[] booleans = {true, false, false, false, false};@Overrideprotected void onStart(Intent intent) {super.onStart(intent);//加载布局this.setUIContent(ResourceTable.Layout_ability_main);//初始化选项卡initTabHost();}/*** 初始化主页面*/private void initTabHost() {tt= (Text) this.findComponentById(ResourceTable.Id_tt);for (int i = 0; i < imgs_normal.length; i++) {dls[i] = (DirectionalLayout) this.findComponentById(dl_ids[i]);images[i] = (Image) this.findComponentById(image_ids[i]);//给所有选项卡添加点击事件dls[i].setClickedListener(listener);}for (int i = 0; i < dlids.length; i++) {layouts[i] = (DirectionalLayout) this.findComponentById(dlids[i]);}//根据当前选项卡的选中状态，切换选项卡的图片状态showState();}/*** 改变当前页面选中状态*/public void showState() {for (int i = 0; i < imgs_normal.length; i++) {if (booleans[i])images[i].setPixelMap(imgs_pressed[i]);elseimages[i].setPixelMap(imgs_normal[i]);}}//给选项卡添加事件监听private Component.ClickedListener listener = new Component.ClickedListener() {@Overridepublic void onClick(Component component) {for (int i = 0; i < imgs_normal.length; i++) {//当第三个选项卡被点击时，跳转至记账页面if (component.getId() == dl_ids[2]) {//跳转至记账的页面present(new AddAccountAbilitySlice(), new Intent());break;}if (component.getId() == dl_ids[i]) {booleans[i] = true;} elsebooleans[i] = false;}showState();//showAbility();}};
}

3.记账页面布局搭建

当用户点击"记账"选项卡的时候，进入用户记账。我们先要搭建记账界面的布局。在layout文件夹下新建xml文件。

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayoutxmlns:ohos="http://schemas.huawei.com/res/ohos"ohos:height="match_parent"ohos:width="match_parent"ohos:orientation="vertical"><!--头部标题，用户切换支出还是收入以及取消的功能--><DirectionalLayoutohos:height="match_content"ohos:width="match_parent"ohos:alignment="center"ohos:background_element="#FFDA44"ohos:orientation="horizontal"ohos:padding="10fp"><Textohos:height="match_parent"ohos:width="match_content"ohos:weight="1"/><Textohos:id="$+id:tv_add_type"ohos:height="match_parent"ohos:width="match_content"ohos:text="支出▼"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="25fp"ohos:weight="4"/><Textohos:id="$+id:tv_add_colse"ohos:height="match_parent"ohos:width="match_content"ohos:text="取消"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"ohos:weight="1"/></DirectionalLayout><!--相对布局，根据收入还是支出的选项，切换显示各种分类--><DependentLayoutohos:height="match_parent"ohos:width="match_parent"><StackLayoutohos:height="match_parent"ohos:width="match_parent"><TableLayoutohos:id="$+id:tl1"ohos:height="match_parent"ohos:width="match_parent"ohos:column_count="1"ohos:row_count="3"><DirectionalLayoutohos:height="match_content"ohos:width="match_parent"ohos:alignment="center"ohos:orientation="horizontal"><DirectionalLayoutohos:height="match_content"ohos:width="match_content"ohos:alignment="center"ohos:margin="10fp"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:img1"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:category_e_catering_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="餐饮"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout><DirectionalLayoutohos:height="match_content"ohos:width="match_content"ohos:alignment="center"ohos:margin="10fp"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:img2"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:category_e_shopping_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="购物"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout><DirectionalLayoutohos:height="match_content"ohos:width="match_content"ohos:alignment="center"ohos:margin="10fp"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:img3"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:category_e_commodity_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="日用"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout><DirectionalLayoutohos:height="match_content"ohos:width="match_content"ohos:alignment="center"ohos:margin="10fp"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:img4"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:category_e_traffic_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="交通"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout></DirectionalLayout><DirectionalLayoutohos:height="match_content"ohos:width="match_parent"ohos:alignment="center"ohos:orientation="horizontal"><DirectionalLayoutohos:height="match_content"ohos:width="match_content"ohos:alignment="center"ohos:margin="10fp"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:img5"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:category_e_vegetable_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="蔬菜"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout><DirectionalLayoutohos:height="match_content"ohos:width="match_content"ohos:alignment="center"ohos:margin="10fp"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:img6"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:category_e_fruite_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="水果"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout><DirectionalLayoutohos:height="match_content"ohos:width="match_content"ohos:alignment="center"ohos:margin="10fp"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:img7"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:category_e_snack_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"ohos:text="零食"ohos:text_alignment="center"ohos:text_font="HwChinese-medium"ohos:text_size="20fp"/></DirectionalLayout><DirectionalLayoutohos:height="match_content"ohos:width="match_content"ohos:alignment="center"ohos:margin="10fp"ohos:orientation="vertical"ohos:weight="1"><Imageohos:id="$+id:img8"ohos:height="50fp"ohos:width="50fp"ohos:image_src="$media:category_e_sport_normal"ohos:scale_mode="stretch"/><Textohos:height="match_parent"ohos:width="match_content"oh

</DirectionalLayout>

4.创建记账功能界面

在slice文件下新建AbilitySlice类继承至BaseAbilitySlice类，加载所有可选中项的图片资源，以及分类名称，虚拟键盘对应的组件对象。

public class AddAccountAbilitySlice extends BaseAbilitySlice {//定义文本组件，控制切换收入和支出的类型，以及关闭记账页面的功能private Text tv_add_type, tv_add_colse;//用于控制当前类型是收入还是支出private boolean bool = false;//获得收入和支出的表格布局private TableLayout tl1, tl2;private DirectionalLayout dl_add;//初始化支出和收入的所有分类的默认图标private int[] image_n = {ResourceTable.Media_category_e_catering_normal,ResourceTable.Media_category_e_shopping_normal,ResourceTable.Media_category_e_commodity_normal,ResourceTable.Media_category_e_traffic_normal,ResourceTable.Media_category_e_vegetable_normal,ResourceTable.Media_category_e_fruite_normal,ResourceTable.Media_category_e_snack_normal,ResourceTable.Media_category_e_sport_normal,ResourceTable.Media_category_e_entertainmente_normal,ResourceTable.Media_category_e_communicate_normal,ResourceTable.Media_category_e_dress_normal,ResourceTable.Media_category_e_beauty_normal,ResourceTable.Media_category_i_wage_normal,ResourceTable.Media_category_i_parttimework_normal,ResourceTable.Media_category_i_finance_normal,ResourceTable.Media_category_i_money_normal,ResourceTable.Media_category_i_other_normal};//初始化支出和收入的所有分类的选中图标private int[] image_p = {ResourceTable.Media_category_e_catering_selected,ResourceTable.Media_category_e_shopping_selected,ResourceTable.Media_category_e_commodity_selected,ResourceTable.Media_category_e_traffic_selected,ResourceTable.Media_category_e_vegetable_selected,ResourceTable.Media_category_e_fruite_selected,ResourceTable.Media_category_e_snack_selected,ResourceTable.Media_category_e_sport_selected,ResourceTable.Media_category_e_entertainmente_selected,ResourceTable.Media_category_e_communicate_selected,ResourceTable.Media_category_e_dress_selected,ResourceTable.Media_category_e_beauty_selected,ResourceTable.Media_category_i_wage_selected,ResourceTable.Media_category_i_parttimework_selected,ResourceTable.Media_category_i_finance_selected,ResourceTable.Media_category_i_money_selected,ResourceTable.Media_category_i_other_selected};//初始化支出和收入的所有分类的确认图标private int[] image_s = {ResourceTable.Media_category_e_catering_s,ResourceTable.Media_category_e_shopping_s,ResourceTable.Media_category_e_commodity_s,ResourceTable.Media_category_e_traffic_s,ResourceTable.Media_category_e_vegetable_s,ResourceTable.Media_category_e_fruite_s,ResourceTable.Media_category_e_snack_s,ResourceTable.Media_category_e_sport_s,ResourceTable.Media_category_e_entertainmente_s,ResourceTable.Media_category_e_communicate_s,ResourceTable.Media_category_e_dress_s,ResourceTable.Media_category_e_beauty_s,ResourceTable.Media_category_i_wage_s,ResourceTable.Media_category_i_parttimework_s,ResourceTable.Media_category_i_finance_s,ResourceTable.Media_category_i_money_s,ResourceTable.Media_category_i_other_s};//初始化支出和收入的所有分类名称private String[] names = {"餐饮", "购物", "日用", "交通", "蔬菜","水果", "零食", "运动", "娱乐", "通讯","服饰", "美容", "工资", "兼职", "理财","礼金", "其他"};//初始化图标的组件对象数组private Image[] images = new Image[image_n.length];//初始化图标的组件对象的idprivate int[] imageIds = {ResourceTable.Id_img1, ResourceTable.Id_img2, ResourceTable.Id_img3,ResourceTable.Id_img4, ResourceTable.Id_img5, ResourceTable.Id_img6,ResourceTable.Id_img7, ResourceTable.Id_img8, ResourceTable.Id_img9,ResourceTable.Id_img10, ResourceTable.Id_img11, ResourceTable.Id_img12,ResourceTable.Id_img13, ResourceTable.Id_img14, ResourceTable.Id_img15,ResourceTable.Id_img16, ResourceTable.Id_img17};//初始化所有分类的选中状态数组private boolean[] booleans={false,false,false,false,false,false,false,false,false,false,false,false,false,false,false,false,false};//用于保存被选中的分类名称private String text;@Overrideprotected void onStart(Intent intent) {super.onStart(intent);//加载布局文件this.setUIContent(ResourceTable.Layout_ability_addaccount);//初始化组件方法initView();}private void initView() {tv_add_colse = (Text) this.findComponentById(ResourceTable.Id_tv_add_colse);tv_add_type = (Text) this.findComponentById(ResourceTable.Id_tv_add_type);tl1 = (TableLayout) this.findComponentById(ResourceTable.Id_tl1);tl2 = (TableLayout) this.findComponentById(ResourceTable.Id_tl2);dl_add = (DirectionalLayout) this.findComponentById(ResourceTable.Id_dl_add);tv_add_type.setClickedListener(listener);tv_add_colse.setClickedListener(listener);for (int i = 0; i < imageIds.length; i++) {images[i]= (Image) this.findComponentById(imageIds[i]);images[i].setClickedListener(listener1);}}//定义收入支出的切换监听事件，以及取消功能的监听事件
private Component.ClickedListener listener = new Component.ClickedListener() {@Overridepublic void onClick(Component component) {switch (component.getId()) {case ResourceTable.Id_tv_add_colse://取消被点击时，关闭记账界面，回到上一界面terminate();break;case ResourceTable.Id_tv_add_type://根据当前状态，切换收入和支出，并同时更改收入和支出的分类选项bool = !bool;if (bool) {tl1.setVisibility(Component.HIDE);tv_add_type.setText("收入▼");tl2.setVisibility(Component.VISIBLE);} else {tl1.setVisibility(Component.VISIBLE);tv_add_type.setText("支出▼");tl2.setVisibility(Component.HIDE);}break;}}};
//添加分类选中监听事件，用于改变被选中的分类出于高亮状态
private Component.ClickedListener listener1=new Component.ClickedListener() {@Overridepublic void onClick(Component component) {for (int i = 0; i < imageIds.length; i++) {if (component.getId()==imageIds[i]){booleans[i]=!booleans[i];if (booleans[i]) {images[i].setPixelMap(image_p[i]);dl_add.setVisibility(Component.VISIBLE);text=names[i];im=image_s[i];}else {images[i].setPixelMap(image_n[i]);dl_add.setVisibility(Component.HIDE);}}elseimages[i].setPixelMap(image_n[i]);}}};
}

5.界面效果展示

完成到这里的时候，可以看到以下功能效果:

那么这时候虚拟键盘的功能还未添加，我们继续看。

6.虚拟键盘的功能实现

在布局中已添加了虚拟键盘的xml代码，这里就不再重复了，我们接下来在AbilitySlice类中初始化虚拟键盘的组件对象。

 //虚拟按键的文本组件id
private int[] tvIds={ResourceTable.Id_tv0,ResourceTable.Id_tv1,ResourceTable.Id_tv2,ResourceTable.Id_tv3,ResourceTable.Id_tv4,ResourceTable.Id_tv5,ResourceTable.Id_tv6,ResourceTable.Id_tv7,ResourceTable.Id_tv8,ResourceTable.Id_tv9,ResourceTable.Id_tvJia,ResourceTable.Id_tvj,ResourceTable.Id_tvDian,ResourceTable.Id_tvd,ResourceTable.Id_tvf};
//初始化按键的文本组件对象数组private Text[] texts=new Text[tvIds.length];
//初始化金额的文本对象private Text tv_money;
//定义变量用于存储金额private int im;
//初始化备注信息的组件对象private TextField tf_info;

在initView方法中添加初始化键盘按键对象代码

 for (int i = 0; i < tvIds.length; i++) {texts[i]= (Text) this.findComponentById(tvIds[i]);texts[i].setClickedListener(listener2);}tv_money= (Text) this.findComponentById(ResourceTable.Id_tv_money);tf_info= (TextField) this.findComponentById(ResourceTable.Id_tf_info);

添加虚拟键盘的按键事件监听

private Component.ClickedListener listener2=new Component.ClickedListener() {@Overridepublic void onClick(Component component) {String s=((Text)component).getText();if ("0123456789".indexOf(s)>=0){tv_money.append(s);}else if ("删除".equals(s)&&tv_money.getText().length()>0){tv_money.setText(tv_money.getText().substring(0,tv_money.getText().length()-1));}else if ("完成".equals(s)){//将数据添加至Sqlite数据库中String ss=tv_add_type.getText().substring(0,tv_add_type.getText().length()-1);ValuesBucket vb=new ValuesBucket();vb.putString("userid", String.valueOf(CommonUtil.user.getId()));vb.putString("type",ss);vb.putString("subtype",text);vb.putInteger("image",im);vb.putString("year",String.valueOf(year));vb.putString("month",String.valueOf(month));vb.putString("day",String.valueOf(day));vb.putDouble("money",Double.parseDouble(tv_money.getText()));vb.putString("info",tf_info.getText());long i=DBUtil.getInstance(rs).insert("tb_jz",vb);if (i>0){showToastDialogShort("记账成功");tv_money.setText("");tf_info.setText("");terminate();}}}};

7.总结

收入和支出的记账功能到这里就完成了，并将收入和支出的明细添加至sqlite数据库中。后面将完善明细模块功能。具体效果图如下展示:
