Question

我希望你能帮助我我试图从我的解析数据库中提取我的Android应用程序（只是一个查看应用程序）的信息基本上我想要做的就是选择我的两个微调器并单击视图点击查看后，它应该查询三个条件

第一个条件：当前解析用户=当前用户（来自数据库）第二个条件：旋转器上的选定项目（旋转月份）=月份（来自数据库）第三个条件：旋转器上的选定项目2（旋转年份）=年份（来自数据库）

然后它将为我提供每个文本视图所需的数据（我只能通过一个条件执行此操作，但我需要将其指定为3个条件）

班级名称：工资单列中的列名称：用户名，月份，年份

我不确定哪种或哪种if语句，开关盒或任何我可以使用的东西，所以我可以适应这三个条件非常感谢帮助！

    a = (Spinner) findViewById(R.id.spinMonth);
ArrayAdapter adapterA = new ArrayAdapter(this,
android.R.layout.simple_spinner_item, month);
a.setAdapter(adapterA);

b = (Spinner) findViewById(R.id.spinYear);
ArrayAdapter adapterB = new ArrayAdapter(this,
android.R.layout.simple_spinner_item, year);
b.setAdapter(adapterB);

  ParseQuery<ParseObject> query = ParseQuery.getQuery("payslip");
    query.whereEqualTo("username",ParseUser.getCurrentUser().getUsername());
    query.findInBackground(new FindCallback<ParseObject>() {
        @Override
      public void done(List<ParseObject> res, ParseException e) {
        if (res == null) {
            Toast.makeText(getApplicationContext(),
                    "Data Retrieved",
                    Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(getApplicationContext(),
                    "Data Not Retrieved",
                    Toast.LENGTH_LONG).show();

显然，我得到了我需要的答案我省略了我使用的第一个解析查询在btnView的on click函数中插入了两个spinner.selected项并创建了三线条件查询，有效！问题是它不适用这三个条件，因为在我的解析数据库年份是数字，在这里我得到它作为一个字符串..

public void onClick(View arg0) {

stringmonth = (String) a.getSelectedItem();
stringyear = (String) b.getSelectedItem();
numyear = Double.valueOf(stringyear);  

ParseQuery<ParseObject> mainQuery = ParseQuery.getQuery("payslip");
mainQuery.whereEqualTo("username",ParseUser.getCurrentUser().getUsername());
mainQuery.whereEqualTo("month",stringmonth);
mainQuery.whereEqualTo("year",numyear);
mainQuery.findInBackground(new FindCallback<ParseObject>()

具有多个条件的Android Parse查询
