Reactjs React Native KeyboardawarScrollView：隐藏键盘时滚动至结束

我们有一个输入很少的表单。当前，当用户单击最后一个输入字段

（a2a_memo_值）

时，表单将向上移动，键盘将打开，当输入失去焦点时，键盘将隐藏，但表单不会向下移动。由于某些元素在视图中不可见，用户需要向下滚动以查看元素。我想在键盘隐藏时滚动到末尾，以便查看表单中的所有元素

这是我的组件

您正在使用

键盘awarScrollView

对吗

然后您需要定义resetSrollToCoords属性，因为您必须告诉组件您剩下的默认位置

因此，只需添加以下内容：

<KeyboardAwareScrollView
  resetScrollToCoords={{ x: 0, y: 0 }}
  scrollEnabled={false}
>
