Java Android Firebase上载图像不工作

我尝试使用以下代码让用户选择图像，选择图像后，图像将自动上载到我的Firebase存储。我在OnCreate函数中初始化了变量storageReference

    private void selectImage() {
        final CharSequence[] options = { "Take Photo", "Choose from Gallery","Cancel" };
        AlertDialog.Builder builder = new AlertDialog.Builder(requireContext());
        builder.setTitle("Add Photo!");
        builder.setItems(options, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int item) {
                if (options[item].equals("Take Photo"))
                {
                    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
                    startActivityForResult(intent, 1);
                }
                else if (options[item].equals("Choose from Gallery"))
                {
                    Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                    intent.setType("image/*");
                    startActivityForResult(intent.createChooser(intent, "Select Image"), 2);
                }
                else if (options[item].equals("Cancel")) {
                    dialog.dismiss();
                }
            }
        });
        builder.show();
    }

private void uploadImage（）
{
if（filePath！=null）{
//上载时显示progressDialog的代码
ProgressDialog=新建ProgressDialog（getContext（））；
progressDialog.setTitle（“上载…”）；
progressDialog.show（）；
//定义storageReference的子级
StorageReference ref=StorageReference.child（mAuth.getCurrentUser（）.toString（））；
//在上载时添加侦听器
//还是形象的失败
ref.putFile（filePath）.addOnSuccessListener（新的OnSuccessListener（）{
@凌驾
成功时公共无效（UploadTask.TaskSnapshot TaskSnapshot）{
//已成功上载图像
//取消对话框
progressDialog.disclose（）；
Toast.makeText（getActivity（），“上传图像！！”，Toast.LENGTH\u SHORT.show（）；
}
}).addOnFailureListener（新的OnFailureListener（）{
@凌驾
public void onFailure（@NonNull异常e）{
//错误，未上载图像
progressDialog.disclose（）；
Toast.makeText（getContext（），“Failed”+e.getMessage（），Toast.LENGTH_SHORT）.show（）；
}
})
.addOnProgressListener（新的OnProgressListener（）{
//用于加载的进度侦听器
//对话框上的百分比
@凌驾
public void onProgress（UploadTask.TaskSnapshot TaskSnapshot）{
双进度=（100.0*taskSnapshot.GetByTestTransferred（）/taskSnapshot.getTotalByteCount（））；
progressDialog.setMessage（“上传”+（int）进度+“%”；
}
});
}
}

我猜uploadImage函数没有被调用，但我不知道为什么。

我发现了，问题是这行代码

if（resultCode==Activity.RESULT\u OK&&data！=null&&data.getData（）==null）

data.getData（）==null

应该是：

data.getData（）！=空

那么当您使用断点调试它时会发生什么呢？你试过那样做吗？

    @SuppressLint("LongLogTag")
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        // If the image is uploaded properly and the resultcode is OK
        // The imagePreview is updated and the image is uploaded
        if(requestCode == 1 || requestCode == 2) {
            if (resultCode == Activity.RESULT_OK && data != null && data.getData() == null) {
                filePath = data.getData();
                try {
                    Bitmap bitmap = MediaStore.Images.Media.getBitmap(requireContext().getContentResolver(), filePath);
                    imagePreview.setImageBitmap(bitmap);
                    uploadImage();
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    private void uploadImage()
    {
        if (filePath != null) {

            // Code for showing progressDialog while uploading
            ProgressDialog progressDialog = new ProgressDialog(getContext());
            progressDialog.setTitle("Uploading...");
            progressDialog.show();

            // Defining the child of storageReference
            StorageReference ref = storageReference.child(mAuth.getCurrentUser().toString());

            // adding listeners on upload
            // or failure of image
            ref.putFile(filePath).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                        @Override
                        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                            // Image uploaded successfully
                            // Dismiss dialog
                            progressDialog.dismiss();
                            Toast.makeText(getActivity(), "Image Uploaded!!", Toast.LENGTH_SHORT).show();
                            }
                    }).addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception e) {
                            // Error, Image not uploaded
                            progressDialog.dismiss();
                            Toast.makeText(getContext(),"Failed " + e.getMessage(),Toast.LENGTH_SHORT).show();
                        }
                    })
                    .addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
                                // Progress Listener for loading
                                // percentage on the dialog box
                                @Override
                                public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                                    double progress = (100.0 * taskSnapshot.getBytesTransferred() / taskSnapshot.getTotalByteCount());
                                    progressDialog.setMessage("Uploaded " + (int)progress + "%");
                                }
                    });
        }
    }
