以下是我的带有标签片段的个人资料活动的代码：
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));
}
}
}

onclick上传图片无效。当我点击按钮时，没有任何反应。
答案 0 :(得分：0)
1）全局声明按钮;
Button button;
2）删除onCreate（）并修改onCreateView（），如下所示：
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）修改onClick方法，如下所示：
@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;
}
}
希望这有帮助。
