Python / Kivy：使用`Up`和`Down`键在RecycleView中选择行
我正在使用python-2.7和kivy。当我运行test.py并点击Test菜单时，屏幕会显示为附加图片
1.如何在屏幕加载时默认highlight第一行？按键盘的up和down键后，应根据up和down键选择行。
2.当我点击任意行时，它会在modify案例中打开。如何使用modify而不是点击来打开ctrl+e案例中的选定行？

答案 1 :(得分：1)
我在类 SelectableRecycleGridLayout 中实现了一些方法，以使用类 LayoutSelectionBehavior 中的方法。有关详细信息，请参阅测试计划，问题，示例和输出。
的关注
原始程序有两个问题会影响性能和内存使用。
第1期
调用方法更新每隔0.0005秒设置小部件的文本。这非常昂贵。请参阅Programming Guide » Events and Properties » Scheduling a repetitive event & Trigger events。
class SelectableButton(RecycleDataViewBehavior, Button):
...
def __init__(self, **kwargs):
super(SelectableButton, self).__init__(**kwargs)
Clock.schedule_interval(self.update, .0005)
def update(self, *args):
self.text = self.rv_data[self.index][self.key]
解决方案 - 问题1
在 RV 类的方法 update 中添加 text 。
class RV(BoxLayout):
...
def update(self):
self.col1_data = [{'text': str(x[0]), 'Id': str(x[0]), 'Name': x[1], 'key': 'Id', 'selectable': True}
for x in self.data_items]
self.col2_data = [{'text': x[1], 'Id': str(x[0]), 'Name': x[1], 'key': 'Name', 'selectable': True}
for x in self.data_items]
第2期
col1_data 和 col2_data 除了 key （ Id 或名称的文本和dictonary）之外是相似的）。当 数据变大 时，应用可能无法运行，因为内存不足，如果确实运行，则效果不佳。解决方案 - 第2期
没有提供解决方案，因为它不属于本主题，而是留给您练习。
测试计划
- 单击测试，显示RecycleView并突出显示第一行。
- 按向下箭头键，突出显示下一行。
- 在最后一行，按下箭头键，第一行高亮显示。
- 按向上箭头键，上一行高亮显示。
- 在第一行，按向上箭头键，最后一行突出显示。
- 按Ctrl + e，弹出窗口显示突出显示的行的信息。
- 鼠标单击未突出显示的任何行，选中鼠标单击的行，然后打开弹出窗口。
- 鼠标点击任意一行，弹出窗口解除后，键盘事件仍然有效！
