我面临的问题是，当我想转移到新活动时，我面临空指针异常，

Fatal Exception: java.lang.NullPointerException

   at dalvik.system.NativeStart.main(NativeStart.java)

我的代码是，

Intent intent = new Intent(getActivity().getApplicationContext(), XYZ.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK |   intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

Answer 1

试试这个

startActivity(new Intent(getActivity(), XYZ.class));

Intent intent = new Intent（getActivity（）。getApplicationContext（），XYZ.class）空指针异常
