【问题描述】：
我想将图片上传到我的 Firebase Storage 存储桶，但它总是返回来自 OnFailureListener 的值。
代码如下：
public class AddProductFragment extends Fragment {
private static final int IMAGE_REQUEST = 1;
private ProgressDialog progressDialog;
private Uri uri;
private EditText mTitle,mPrice;
private Button mBtn,mUpload;
private ImageView mImage;
private FirebaseStorage mStorageRef;
private StorageReference mRef;
public AddProductFragment() {
mStorageRef = FirebaseStorage.getInstance();
mRef = mStorageRef.getReference().child("images");
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.add_product_fragment,container,false);
find(v);
onClick();
return v;
}
private void find(View v) {
mTitle = (EditText)v.findViewById(R.id.singleProductTitle);
mPrice = (EditText)v.findViewById(R.id.singleProductPrice);
mBtn = (Button) v.findViewById(R.id.addProductSelectImageBtn);
mImage = (ImageView)v.findViewById(R.id.addProductImage);
mUpload = (Button)v.findViewById(R.id.uploadBtn);
}
private void onClick() {
mBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent,"Select Picture"), IMAGE_REQUEST);
}
});
mUpload.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
progressDialog = new ProgressDialog(getActivity());
progressDialog.setMax(100);
progressDialog.setMessage("Uploading...");
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.show();
progressDialog.setCancelable(false);
String title = mTitle.getText().toString();
String price = mPrice.getText().toString();
if (!title.isEmpty() && !price.isEmpty()) {
Product product = new Product();
Uri file = Uri.fromFile(new File(getRealPathFromURI(uri)));
mRef.child("original").child(product.getStringId());
mRef.putFile(file).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
@Override
public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();
//sets and increments value of progressbar
progressDialog.incrementProgressBy((int) progress);
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Toast.makeText(getActivity(), "Error uploading....", Toast.LENGTH_SHORT).show();
progressDialog.dismiss();
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Uri downloadUrl = taskSnapshot.getDownloadUrl();
Toast.makeText(getActivity(),"Upload successful",Toast.LENGTH_SHORT).show();
//TODO: redirect to the uploaded product;
progressDialog.dismiss();
}
});
}
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == IMAGE_REQUEST && resultCode == RESULT_OK) {
try {
uri = data.getData();
Bitmap bitmap = null;
if(uri != null) {
try {
bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), uri);
} catch (IOException e) {
e.printStackTrace();
}
mImage.setImageBitmap(bitmap);
} else {
Toast.makeText(getActivity(), "Uri not found...", Toast.LENGTH_SHORT).show();
}
} catch (NullPointerException e) {
e.getMessage();
}
}
}
private String getRealPathFromURI(Uri contentURI) {
String thePath = "no-path-found";
String[] filePathColumn = {MediaStore.Images.Media.DISPLAY_NAME};
Cursor cursor = getActivity().getContentResolver().query(contentURI, filePathColumn, null, null, null);
if(cursor.moveToFirst()){
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
thePath = cursor.getString(columnIndex);
}
cursor.close();
return thePath;
}
}
这是一个例外：
/com.example.cmd.pop E/StorageException: /image-0-02-05-64dcdbd29d607a4421b258b2adbfb848cf3262ee096a8b0ab2dbecd22631feea-V.jpg： 打开失败：ENOENT（没有这样的文件或目录）
java.io.FileNotFoundException: /image-0-02-05-64dcdbd29d607a4421b258b2adbfb848cf3262ee096a8b0ab2dbecd22631feea-V.jpg： 打开失败：ENOENT（没有这样的文件或目录）
【问题讨论】：
-
好吧，OnFailureListener 有一个例外 - 您在代码中完全忽略了它。你看过那个例外吗？我希望它能提供有关问题所在的有用信息。
-
@JonSkeet 我已经更新了帖子。

好吧，听起来你应该调查一下 - 如果找不到本地文件，那并不是真正的 Firebase 问题。
