java - Android - 如何将图像存储在已创建的 Firestore 文件夹中

Question

public void upload() {
    if(imageUri!=null) {
        StorageReference reference=storageReference.child("customers/");
        reference.putFile(imageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                // Toast.makeText(getApplicationContext(),"File Uploaded",Toast.LENGTH_LONG).show();
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Toast.makeText(getApplicationContext(),e.getMessage(),Toast.LENGTH_LONG).show();
            }
        }).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                double totalProgress=(100*taskSnapshot.getBytesTransferred())/taskSnapshot.getTotalByteCount();
                // Toast.makeText(getApplicationContext(),"File uploaded"+(int)totalProgress,Toast.LENGTH_LONG).show();
            }
        });
    }
}

在 Firebase 存储中，有一个名为“customers”的文件夹，我想在其中存储所选图像。当我尝试上传图像时，它将其存储为不同的文件夹，而不是已创建的文件夹。这里，“customers”是已经创建的文件夹。

public void upload(String imageName) {
    if(imageUri!=null) {
        StorageReference reference=storageReference.child("customers).child(imageName);
        reference.putFile(imageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                // Toast.makeText(getApplicationContext(),"File Uploaded",Toast.LENGTH_LONG).show();
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Toast.makeText(getApplicationContext(),e.getMessage(),Toast.LENGTH_LONG).show();
            }
        }).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                double totalProgress=(100*taskSnapshot.getBytesTransferred())/taskSnapshot.getTotalByteCount();
                // Toast.makeText(getApplicationContext(),"File uploaded"+(int)totalProgress,Toast.LENGTH_LONG).show();
            }
        });
    }
}

为了检索图像名称，请使用:-

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        Uri selectedImageUri = data.getData( );
        String picturePath = getPath( getActivity( ).getApplicationContext( ), selectedImageUri );
        Log.d("Picture Path", picturePath);
        upload(picturePath);

    }
}

public static String getPath( Context context, Uri uri ) {
    String result = null;
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver( ).query( uri, proj, null, null, null );
    if(cursor != null){
        if ( cursor.moveToFirst( ) ) {
            int column_index = cursor.getColumnIndexOrThrow( proj[0] );
            result = cursor.getString( column_index );
        }
        cursor.close( );
    }
    if(result == null) {
        result = "Not found";
    }
    return result;
}
