This is my code, the onActivityCreated () to add the activity, but no response after click the button, the Android small white,,,

 public class Fragment2 extends fragments {
Private Button BTN. 
@ Nullable 
@ Override 
Public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {


View the View=inflater. Inflate (R.l ayout. Fragment2, container, false); 
Return the view; 

} 

@ Override 
Public void onActivityCreated (@ Nullable Bundle savedInstanceState) {
Super. OnActivityCreated (savedInstanceState); 
BTN=(Button) getActivity (). The findViewById (R.i which est_bt); 
BTN. SetOnClickListener (new View. An OnClickListener () {
@ Override 
Public void onClick (View View) {
Toast. MakeText (getContext (), "success2", Toast. LENGTH_SHORT), show (); 

StartActivity (new Intent (getActivity (), PayActivity. Class)); 
} 
}); 

} 
}

CodePudding user response:

Fragments need getActivity (). StartActivity (new Intent (getActivity (), PayActivity. Class));

CodePudding user response:

Why the activity of the button to set the click event at the fragments? If it is a fragment of the button, you should set the click event in onViewCreated method

CodePudding user response:

reference 1/f, the wind light cloud light v10 reply:

fragments inside need to getActivity () startActivity (new Intent (getActivity (), PayActivity. Class));

In addition you need in onViewCreated method using the findViewById to obtain control
