数据范围筛选器在Android中使用的SQLite中不起作用

我运行SQLite在两个范围内为创建的执行选择数据。要从两个日期之间选择数据，我使用以下语句

 public ArrayList<LoopExecution> getDateRangeLoop(Date fromDate, Date toDate, int limit) {
        String query = "SELECT * FROM"
                + " loopexe "
                + " WHERE "
                + " created_on "
                + " BETWEEN " + fromDate.getTime()
                + " AND " +toDate.getTime();

     Cursor cursor = database.rawQuery(query, null);
     ArrayList<LoopExecution> loopExecutions = new ArrayList<LoopExecution>();
            if(cursor.moveToNext()) {
                do {
                    LoopExecution loopExecution = new LoopExecution();
                    loopExecution.setId(cursor.getString(0));
                    Date createdOn = new Date(cursor.getLong(1));
                    loopExecution.setCreatedOn(createdOn);
                    loopExecution.setCreatedBy(cursor.getString(2));
                    loopExecution.setLoopId(cursor.getString(3));
                    loopExecution.setLoopStatus(LoopExecution.LoopStatus.valueOf(cursor.getString(4)));
                    loopExecution.setImage(cursor.getString(5));
                    loopExecution.setResultJson(cursor.getString(6));
                    loopExecution.setBgImage(cursor.getString(7));
                    loopExecution.setTrendImage(cursor.getString(8));
                    loopExecutions.add(loopExecution);
                } while (cursor.moveToNext());
            }
            cursor.close();
            return loopExecutions;
        }

确保您的日期格式为yyyy-MM-dd

尝试将日期放入DATE（）标志中

String query = "SELECT * FROM"
            + " loopexe "
            + " WHERE "
            + " created_on "
            + " BETWEEN DATE('" +fromDate.getTime() + "') "
            + " AND DATE('" + toDate.getTime() + "') ";

选项一（如果在上创建的

类型为
整数
）：

由于要使用长时间戳（只是一个数字），
getTime（）
检索该时间戳，因此必须使用
=
运算符

String query = "SELECT * FROM"
   + " loopexe "
   + " WHERE "
   + " created_on "
   + " >= " + fromDate.getTime()
   + " < " + toDate.getTime();

这只是一个硬编码日期的示例。要使其动态化，请使用：

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
String date = formatter.format(today);

String query = "SELECT * FROM"
 + " loopexe "
 + " WHERE "
 + " created_on "
 + " BETWEEN '2017-07-10'"
 + " AND '2017-07-14'";

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
String date = formatter.format(today);
