视图仅刷新一次并显示新卡片,我不知道为什么,当我更改为Tab3(谷歌地图)时。
移至tab3(谷歌地图)并再次移至tab1后(仅刷新Tab1,但不刷新tab2,启动后tab2在tab1上显示相同,但不刷新)[3]
问题是,如何实时刷新或代码发生什么变化?
一些MainActivity Java代码

List<Locales> data = AllLocales;
List<Locales> output = new ArrayList<>();
for (Locales item : data) {

output.add(item);
} else {
if (item.getRubro().toLowerCase().startsWith(getQuer().toLowerCase())) {
output.add(item);
}
}
}
AllLocales = output;
