在我提供的代码中，我使用一个平面列表，它呈现一个包含多个 TextInut 组件的行元素，这里的问题是当我尝试编辑位于平面列表末尾的 Textinput 组件时，键盘出现然后消失，但是当我编辑任何文本时平面列表开头的另一行可以正常工作，
我认为这是因为当我单击平面列表末尾的一行时，键盘会出现并覆盖该区域，以便设备在那之后决定我没有输入任何输入，因此它再次隐藏键盘。 尝试使用 KeyboardAvoidingView 但没有成功

预期的行为是能够在键盘不消失的情况下编辑所有元素。
尝试
removeClippedSubviews={false}FlatList 将删除键盘覆盖的项目子视图，以获得更好的性能https://reactnative.dev/docs/flatlist#removeclippedsubviews。
