您好我正在尝试创建个人资料屏幕,用户可以上传自己的个人资料图片,并将ImageView更改为他们上传的内容。但是当我使用这个Upload profile image for a user Firebase作为参考时,我开始将图像上传到数据库时遇到了错误。
我的代码
public class userMain extends Fragment {
private TextView userfirstName,usersecondName,userNumber,userGender,userEmail,userDate;
private Button btnChoose, btnUpload;
private ImageView imageView;
private Uri filePath;
private FirebaseStorage storage;
private StorageReference storageReference;
private final int PICK_IMAGE_REQUEST = 71;
public userMain() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_user_main, container, false);
btnUpload = (Button) view.findViewById(R.id.savePhoto);
imageView = (ImageView) view.findViewById(R.id.imageView3);
userfirstName = (TextView) view.findViewById(R.id.firstnametv);
usersecondName = (TextView) view.findViewById(R.id.secondnametv);
userNumber = (TextView) view.findViewById(R.id.numbertv);
userGender = (TextView) view.findViewById(R.id.gendertv);
userEmail = (TextView) view.findViewById(R.id.emailtv);

storage = FirebaseStorage.getInstance();
storageReference = storage.getReference();
String useruid=user.getUid();

imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
chooseImage();
}
});
