如何将列表视图移动到 MDToolbar 下方

Question

正如您在屏幕截图中看到的那样，Listview 的顶部项目与 mdtoolbar 混合在一起。我想在 MDtoolbar 下方显示。我尝试在 kv 代码中更改 MDList 中的 pos_hint 属性。但它不动。我怎样才能把它移到下面？有没有办法把它贴在工具栏下面没有pos_hint

.py 文件

class ListApp(Screen):
    built = BooleanProperty(False)

    def build(self):
        if self.built:
            return
        self.built = True
        self.popup = Popup(title='Calculating Stoploss', content=Image(source='please_wait.gif'))
        self.popup.open()
        threading.Thread(target=self.actual_build).start()

    def actual_build(self):
        end = datetime.today().date()
        start = end

        i = 0
        fl = len(file.index)
        try:
            for index in range(fl):

                for index in range(1):
                    columnSeriesObj2 = file.iloc[:, 0]

                    df = web.DataReader(columnSeriesObj2.values[i],'yahoo', start, end,retry_count=3)
                    print(df.head())
                    Objname = file.iloc[:, 2]
                    columnSeriesObj = df.iloc[:, 3]
                    columnSeriesObj1 = file.iloc[:, 1]
                    ObjStoploss = file.iloc[:, 3]

                    cp = iter(columnSeriesObj.values)
                    pp = iter(columnSeriesObj1.values)
                    pp1 = next(pp)
                    cp1 = columnSeriesObj.values[0]
                    sl = columnSeriesObj1.values[i] - (columnSeriesObj1.values[i] * (ObjStoploss.values[i]/100))

                    if cp1 <= sl:
                        Clock.schedule_once(partial(self.add_loss, Objname.values[i], str(cp1), str(sl)))
