Hier ist mein Code für ein Profil Aktivität Tabbed Fragmente:

PROFILE_ACTIVITY.java

public class ProfileActivity extends AppCompatActivity implements View.OnClickListener { 


    private FirebaseAuth firebaseAuth; 
    private Button buttonswitch; 
    private Button buttons; 
    private Button buttonLogout; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_profile); 
     firebaseAuth = FirebaseAuth.getInstance(); 

     //if the user is not logged in 
     //that means current user will return null 
     if (firebaseAuth.getCurrentUser() == null) { 
      //closing this activity 
      finish(); 
      //starting login activity 
      startActivity(new Intent(this, LoginActivity.class)); 

     } 
     FirebaseUser user = firebaseAuth.getCurrentUser(); 

     //initializing views 

     TextView textViewUserEmail = (TextView) findViewById(R.id.textViewUserEmail); 
     buttonLogout = (Button) findViewById(R.id.buttonLogout); 
     buttonswitch = (Button) findViewById(R.id.dashboard); 

     //displaying logged in user name 
     textViewUserEmail.setText("Welcome " + user.getEmail()); 

     //adding listener to button 
     buttonLogout.setOnClickListener(this); 
     buttonswitch.setOnClickListener(this); 

    } 

    @Override 
    public void onClick(View view) { 
     //if logout is pressed 
     if (view == buttonLogout) { 
      //logging out the user 
      firebaseAuth.signOut(); 
      //closing activity 
      finish(); 
      //starting login activity 
      startActivity(new Intent(this, LoginActivity.class)); 
     } 

     if (view == buttonswitch) { 
      startActivity(new Intent(this, tabbed.class)); 
     } 
    } 
} 

und hier ist mein Fragment:

public class fupload extends Fragment implements View.OnClickListener{ 

     FragmentManager fragmentManager = getFragmentManager(); 
     FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); 

     // TODO: Rename parameter arguments, choose names that match

onclick upload image funktioniert nicht. Wenn ich auf den Knopf klicke, passiert nichts.

Answer 1

1) Schaltfläche global deklarieren;

Button button; 

2) entfernen onCreate() und modifizieren onCreateView() wie folgt:

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    View view = inflater.inflate(R.layout.fragment_fupload, container, false); 

     if (getArguments() != null) { 
      mParam1 = getArguments().getString(ARG_PARAM1); 
      mParam2 = getArguments().getString(ARG_PARAM2); 
     } 
     mstorage = FirebaseStorage.getInstance().getReference(); 
     buttons = (Button) view.findViewById(button1); 
     buttons.setOnClickListener(this); 
     return view; 
} 

3) Ändern onClick Methode wie folgt:

@Override 
public void onClick(View v) { 
    switch(v.getId()){ 
     case R.id.button1: 
      Toast.makeText(getActivity(), "Button is working!", Toast.LENGTH_SHORT).show(); 
      Intent intent = new Intent(Intent.ACTION_PICK); 
      intent.setType("images/*"); 
      startActivityForResult(intent, GALLERY_INTENT); 
      break; 
    } 
} 

Hoffnung, das hilft.
