Python：如何在RecycleView中添加垂直滚动
我正在使用Python-2.7和kivy。
我运行test.py然后显示一个菜单Test。当我单击它时显示list数据。有人可以告诉我如何scrollbar在列表中添加垂直方向。

问题
\n\n\n\n\n如何仅在 customerId 列中设置文本右对齐，而其他列\n 应左对齐？
\n
解决方案
\n\n片段
\n\ndef apply_selection(self, rv, index, is_selected):\n \'\'\' Respond to the selection of items in the view. \'\'\'\n self.selected = is_selected\n self.text_size = self.size\n if index == rv.data[index][\'range\'][0]:\n self.halign = \'right\'\n else:\n self.halign = \'left\'\n输出
\n\n
标签 - 文本垂直生长并以一定宽度换行
\n\n可以垂直增长但以一定宽度包裹文本的标签：
\n\nLabel:\n size_hint_y: None\n text_size: self.width, None\n height: self.texture_size[1]\n要在其上滚动 GridLayout\xe2\x80\x99s X 轴/水平和 Y 轴/垂直，请将 size_hint 属性设置为 (None, None)。
\n\nScrollView - ScrollEffect、scroll_type、bar_width 等
\n\n\n\n\n\n\n默认情况下，ScrollView 允许沿 X 轴和 Y 轴滚动。您可以通过将 do_scroll_x 或 do_scroll_y 属性设置为 False 来显式禁用轴上的滚动。
\n\n要在其上\xe2\x80\x99s Y 轴/垂直滚动 GridLayout，请将子\xe2\x80\x99s\n 宽度设置为 ScrollView 的宽度 (size_hint_x=1)，并将 size_hint_y 属性\n 设置为 None ：
\n\n当滚动超出 ScrollView 的边界时，它使用 ScrollEffect 来处理过度滚动。
\n\n滚动类型
\n\n设置用于滚动视图内容的滚动类型。\n 可用选项有: [\xe2\x80\x98content\xe2\x80\x99]、[\xe2\x80\x98bars\xe2\x80\x99]、 [\xe2\x80\x98bars\xe2\x80\x99，\xe2\x80\x98内容\xe2\x80\x99]
\n\n[\xe2\x80\x98bars\xe2\x80\x99] 通过拖动或滑动滚动条来滚动内容。
\n
\n\n\n列数最小值
\n\n每列的最小宽度的字典。字典键是\n列号，例如 0, 1, 2\xe2\x80\xa6
\n\ncols_minimum 是一个 DictProperty，默认为 {}。
\n
片段
\n\n<RV>:\n row_controller: row_controller\n\n bar_width: 10\n bar_color: 1, 0, 0, 1 # red\n bar_inactive_color: 0, 0, 1, 1 # blue\n effect_cls: "ScrollEffect"\n scroll_type: [\'bars\']\n\n data: root.rv_data\n viewclass: \'SelectableButton\'\n\n SelectableRecycleGridLayout:\n id: row_controller\n key_selection: \'selectable\'\n cols: root.total_col_headings\n cols_minimum: root.cols_minimum\n default_size: None, dp(26)\n default_size_hint: 1, None\n size_hint: None, None\n height: self.minimum_height\n width: self.minimum_width\n orientation: \'vertical\'\n multiselect: True\n touch_multiselect: True\n下面的例子演示了：
\n\n- \n
- 表格标题在 X 轴上滚动。 \n
- 支持X轴和Y轴滚动。 \n
- 支持在弹出窗口中 Y 轴滚动。 \n
- 适用于数据库表中的任何列。 \n
- 使用 GridLayout cols_minimum改变列宽。 \n
- 将两个 RecycleView 合二为一，因为不需要仅用于 ID 的 RecycleView。 \n
- 可选按钮。 \n
