记一次，Activity+Viewpager+Fragment ，fragment 中启动startActivityForResult，并在fragment 的onActivityResult 接收

直接采用 

Intent intent = new Intent(getContext(), Activity.class);
startActivityForResult(intent, 88);

Override public void onActivityResult(int requestCode, int resultCode, Intent data) {

super.onActivityResult(requestCode, resultCode, data);

if (requestCode == 88 && resultCode == RESULT_OK) { } }

//而不是采用下面两种， 下面的两种方法都只能在 Fragment 所依附的 activity的onActivityResult 方法接受到回调

Intent intent = new Intent(getContext(), Activity.class);

getcontext.startActivityForResult(intent, 88);

getacativity.startActivityForResult(intent, 88);
