JUMP跳转之后List被置为空

setEvents()方法中写下代码直接跳转B界面。我打断点发现刚开始跳转的时候list的数据为四条，B界面关闭回来list直接为空 设置数据报错应用崩掉
jump(datas.get(i).getmClass(), new OnJumpResponseListener() {
@Override
public void OnResponse(JumpParameter jumpParameter) {
if (jumpParameter == null) {
toast("未返回任何数据");
datas.get(finalI).setmResult("false");
} else {
String result_text = String.valueOf(jumpParameter.get("返回数据1"));
if (result_text.equals("true")) {
datas.get(finalI).setmResult("true");
}else {
datas.get(finalI).setmResult("false");
}
}
}
});

Start at setEvents() and trace the jump callback through the transition to and return from the B interface. Reproduce the case with four list entries, then inspect why the list is empty before datas.get(finalI) is updated. Done means returning from B preserves the list and the result update no longer crashes the app.
