Question

我有2个活动（Nota和Pembayaran）。

在Nota活动中，我在textview上显示了一些数据。单击layout_link_pembayaran时，将显示Pembayaran活动。

在Pembayaran活动中，我显示了一个表单，当表单提交后，它将用于Nota活动。

我的问题是Nota活动仍然显示旧数据，而不是基于我在Pembayaran活动中提交的新数据的最新数据。

此处是Nota活动包com.example.arif.celmira;

我尝试使用finish()和pindah.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); pindah.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); pindah.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);，但没有人工作。

在Pembayaran活动中提交表单后，Nota活动如何启动/重新启动？

更新我删除了有关上传图像的所有内容，因此在Pembayaran活动中仅发布Edittext，不再包括上传图像，然后它有效，intent可以完成（），当Intent进入Nota活动时，onCreate Nota活动有效（可以使用Volley StringRequest加载新数据）。

据此，我认为问题是意图在Pembayaran活动上选择图片

Answer 1

您可能需要startActivityForResult()而不是startActivity()。然后，在您的Pembayaran活动上设置Extras结果，并在Nota活动上收听onActivityResult()，您可以在其中设置新值。

最诚挚的问候。

Answer 2

在Nota活动中，您应该使用 startActivityForResult（）代替 startActivity（），然后在方法中覆盖方法 onActivityResult（）同班。在您的Pembayaran活动中，使用 setResult（）方法发送新的意图，这样结果将进入Nota活动中的回调 onActivityResult（）。试试这个。

Answer 3

返回到Nota Activity后，不会再次呼叫

onCreate()。

也许您应该尝试将StringRequest移到onResume()/onStart()中，每次显示该活动时都会调用它。

最佳

android finish（）未完成我的活动
