我开发了一个可以自动记账的app 取名为simpleBill
记录一下开发过程中遇到的一些知识点
在开发的过程中发现是java加上ui的xml界面，所以很快就上手了

首先是Addrecord页面

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        tools:context=".ui.addRecord.AddRecordActivity">
        <!--<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"-->
        <!--    android:layout_width="match_parent"-->
        <!--    android:layout_height="match_parent">-->
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="添加新账单"
            android:textSize="40dp"
            android:layout_gravity="center"
            />
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_marginTop="50dp"
            >
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="金额："
                android:textSize="20dp"
                android:layout_marginRight="20dp"
                android:layout_marginTop="3dp"

首先设计了记录的字段，我设计的账单记录字段包括金额，描述，类别，来源，日期，收支。

金额可以手动填写或者无障碍服务识别特定页面自动填写。
描述可以手动填写或者无障碍服务识别特定页面自动填写。
类别需要选择，此处设计了弹窗进行选择。

首先我在程序内部存储生成了一个leibie.txt

      File dir = AddRecordActivity.this.getFilesDir();
            // 创建文件对象
            File file = new File(dir, "leibie.txt");
            // 如果文件不存在，则创建它
            if (!file.exists()) {
                try {
                    file.createNewFile();
                } catch (IOException e) {
                    throw new RuntimeException(e);
                }
            }
            ArrayList<String> leibieArraylist = readFile("leibie.txt",AddRecordActivity.this);
            if (leibieArraylist.size() <= 1){
                writeToFile("添加...","leibie.txt",AddRecordActivity.this,false);
            }

然后在点击类别时用popupwindow进行弹窗（收支用spinner，感觉spinner效果不太好，所以用了popupwindow）

  leibieEdit.setOnClickListener(this);
            leibieEdit.setOnFocusChangeListener(new View.OnFocusChangeListener() {
                @Override
                public void onFocusChange(View v, boolean hasFocus) {
                    if (hasFocus) {
                        try {
                            showPopupLeibieList(v,leibieEdit,leibieListView);
                        } catch (IOException e) {
                            throw new RuntimeException(e);
                        }
                    }
                }
            });

弹出pupupwindow的代码

  private void showPopupLeibieList(View anchorView, EditText editText, ListView listView) throws IOException {
        // 初始化ListView和适配器（这里使用ArrayAdapter作为示例）

         leibieItems = readFile("leibie.txt",AddRecordActivity.this);
        listView = new ListView(this);
           ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, leibieItems);//弹窗固定写法 具体原理没研究

        listView.setAdapter(adapter);


        // 设置ListView的高度（可选，根据你的需要）
        int height = getResources().getDimensionPixelSize(R.dimen.list_popup_height);
        ListView.LayoutParams params = new ListView.LayoutParams(ListView.LayoutParams.MATCH_PARENT, height);
        listView.setLayoutParams(params);
        // 初始化PopupWindow，并设置宽高和焦点等属性
        popupWindow = new PopupWindow(listView, editText.getWidth() , height, true);
        Drawable drawable = getResources().getDrawable(R.drawable.popupwindow_border);
        popupWindow.setBackgroundDrawable(drawable);
        popupWindow.showAsDropDown(anchorView);//在锚点的正下方显示
        // 设置ListView的点击监听器
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                // 处理点击事件，例如更新输入框的值并关闭PopupWindow
                if (position == leibieItems.size() -1 ){
                    showPopupAddLeibie();
                    popupWindow.dismiss();
                }else{
                    editText.setText(leibieItems.get(position));
                }

                popupWindow.dismiss();
            }
        });
        // 设置PopupWindow的触摸监听器（可选）
   
    }

来源很简单，用spinner

ArrayList<String> laiyuanNames = (ArrayList<String>) accountHelper.getAllNames();
            ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, laiyuanNames);
            // 将适配器设置给Spinner
            laiyuan.setAdapter(adapter);

时间用了日期选择器

private EditText dateEdit;
  SimpleDateFormat customFormat = new SimpleDateFormat("yyyy-MM-dd");
            String formattedDate = customFormat.format(new Date());

            dateEdit.setText(formattedDate);
            dateEdit.setOnFocusChangeListener(new View.OnFocusChangeListener() {

                @Override
                public void onFocusChange(View v, boolean hasFocus) {
                    if (hasFocus) {
                        CommonUtils.showDatePickDlg(AddRecordActivity.this,dateEdit,dateEdit.getText().toString());
                    }
                }
            });

日期选择器弹窗是多用的，因此提取出来至CommonUtils类

  public static void showDatePickDlg(Context context, EditText editText, String dateStr) {
        Calendar calendar = Calendar.getInstance();
        Date date = null;
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        try {
            date = sdf.parse(dateStr);

        }catch (Exception e){}

        if (date!= null){
            calendar.setTime(date);
        }

        DatePickerDialog datePickerDialog = new DatePickerDialog(context, new DatePickerDialog.OnDateSetListener() {

            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                editText.setText(year + "-" +  String.format("%02d", monthOfYear+1) + "-" +  String.format("%02d", dayOfMonth));//最终那个edittext里显示的格式 可在这里调整，monthOfYear从0开始
            }
        }, calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH),calendar.get(Calendar.DAY_OF_MONTH));
        datePickerDialog.show();

    }

来源用了spiiner
spinner的数据来源区数据库中读取所有accountName

  ArrayList<String> laiyuanNames = (ArrayList<String>) accountHelper.getAllNames();
            ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, laiyuanNames);
            // 将适配器设置给Spinner
            laiyuan.setAdapter(adapter);

收支
收支也用了spinner，选项只有“收入”“支出”，因此直接在xml中定义

<Spinner
                android:id="@+id/shouzhi"
                style="@style/Base.Widget.AppCompat.Spinner.Underlined"
                android:layout_width="143dp"
                android:layout_height="50dp"
                android:layout_weight="1"
                android:entries="@array/spinner_shouzhi" />

在values包中创建一个xml，名称随便添加如下代码。

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="spinner_shouzhi">
        <item>支出</item>
        <item>收入</item>
    </string-array>
</resources>

添加按钮

private void addRecord(){
		//获取所有的字符串
        String adesc = miaoshu.getText().toString();
        adesc = validateDesc(adesc);//校验是否有英文逗号，便于后期导出数据的处理。如果有英文逗号换成中文逗号。因为导出数据功能使用了英文逗号祚分隔符。
        String acount = jine.getText().toString();
        String adate = dateEdit.getText().toString();
        String ashouzhi = shouzhi.getSelectedItem().toString();
        String asource = laiyuan.getSelectedItem().toString();
        String aleibie = leibieEdit.getText().toString();

        if(acount.equals("")){
            Toast.makeText(this, "金额不能为空！", Toast.LENGTH_SHORT).show();
        } else if (adesc.equals("")) {
            Toast.makeText(this, "描述不能为空！", Toast.LENGTH_SHORT).show();
        } else if (adate.equals("")) {
            Toast.makeText(this, "日期不能为空!", Toast.LENGTH_SHORT).show();
        }else if(ashouzhi.equals("")){
            Toast.makeText(this, "收支不能为空！", Toast.LENGTH_SHORT).show();
        }
        else if(asource.equals("")){
            Toast.makeText(this, "来源不能为空！", Toast.LENGTH_SHORT).show();
        }
        else if(aleibie.equals("")){
            Toast.makeText(this, "类别不能为空！", Toast.LENGTH_SHORT).show();
        }
        else{
            if (ashouzhi.equals("支出")){
                acount = '-' + acount;
            }
            BillRecord record = new BillRecord();
            record.setSource(asource);
            record.setCount(acount);
            record.setDescription(adesc);
            record.setCreateDate(adate);
            record.setShouzhi(ashouzhi);
            record.setLeibie(aleibie);
            long res = billRecordHelper.addRecord(record);
            addButton.setEnabled(false);
            addButton.setTextColor(0xFFD0EFC6);
            if(res!=-1){
                Toast.makeText(this, "添加成功", Toast.LENGTH_SHORT).show();
                //如果是微信或支付宝跳转过来的 区分手动添加记录的情况
                if (isfrom("accessibility.alipay") || isfrom("accessibility.wechat")){
                    AlertDialog.Builder builder = new AlertDialog.Builder(this);
                    builder
                            .setMessage("是否留在此地？")
                            .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                                        public void onClick(DialogInterface dialog, int id) {
                                            go(AddRecordActivity.this, MainActivity.class);//点击确定后去到app的主页。
                                            Intent intent = new Intent("REFRESH_ACTIVITY_ACTION");//发送这个action让主页刷新，否则主页不刷新。
                                            sendBroadcast(intent);
                                            finish();
                                        }
                                    }
                            )
                            .setNegativeButton("返回", new DialogInterface.OnClickListener() {
                                @Override

                                    Intent intent1 = new Intent("REFRESH_ACTIVITY_ACTION");
                                    sendBroadcast(intent1);

回到主页按钮
没啥好说的，跳转至主页

Intent intent = new Intent(this,MainActivity.class);
          intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
          startActivity(intent);

类被管理按钮
跳转至类别管理页面

Intent intent = new Intent(AddRecordActivity.this,LeibieManageActivity.class);
            intent.putExtra("FROM_ACTIVITY", "AddRecordActivity");
            startActivity(intent);

以上是手动添加记录的代码，如果是使用无障碍服务从微信/支付宝跳转过来的就直接读取数据
判断函数其实就是判断字符串相等

  private boolean isfrom(String action){
        if (formAction.equals(action)){
            return true;
        }

    }

 if (isfrom("accessibility.wechat") || isfrom("accessibility.alipay")){
