Answer 1

您可以通过创建新的onFinish()：

在Intent中打开活动

Intent intent = new Intent(textView.getContext(), ActivityA.class);                      
startActivity(intent);

要启动该服务，您可以致电：

startService(new Intent(this, YourServiceClass.class));

Answer 2

通过将Intent传递给startService（）来启动服务以执行一次性操作。

intent dialogIntent = new Intent(this, MyActivity.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(dialogIntent);

试试这个。

从服务开始活动
