Actually I saw a yt video of how to intent fragment and acticity and that is what I tried but don"t know how the error is coming.The error which I am having is ** java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setOnClickListener(android.view.View$OnClickListener)' on a null object reference at com.example.photoframeapp.HomeFragment.onCreateView(HomeFragment.java:31)**.I tried to sort out but I am not able to .
this is my HomeFragment.java class
public class HomeFragment extends Fragment {
TextView beginners;
public HomeFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_home, container, false);
beginners.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(getActivity(),mainpage.class));
}
});
return view;
}
}
this is my mainpage.java file
public class mainpage extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainpage);
}
}
fragment_home.xml file
