我已经在firebase存储中上传了多个图像，现在我想在数据中添加它们的URL以及其他数据 . 我该怎么做？我在日志中获取所有网址，但当我尝试使用以下代码时应用程序崩溃？
storageReference = FirebaseStorage.getInstance().getReference();
databaseReference= FirebaseDatabase.getInstance().getReference().child("Blog Data");
final DatabaseReference newBlog = databaseReference.push();
for (int i = 0; i < list.size(); i++)
{
if (imageUri != null) {
final StorageReference ref = filePath.child(fileName[i]);
final int y = i;
ref.putFile(imageUri[i])
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.cancel();
Toast.makeText(getApplicationContext(), "Uploaded successfuly", Toast.LENGTH_LONG).show();
downloadUri[y] = taskSnapshot.getDownloadUrl();
Log.i("DownlaodUri ", "downlaod URi is :"+downloadUri[y].toString());
newBlog.child("image_"+y+1).setValue(downloadUri[y]);
}
}
)
我还尝试在第一次循环后使用另一个for循环来存储URL . 它将所有数据保存在数据库中，但不存储URL .
这是我尝试的方式 .
}// end of upper for loop
DatabaseReference newBlog = databaseReference.push();
newBlog.child("title").setValue(title);
newBlog.child("desc").setValue(desc);
for(int i = 0; i<list.size(); i++) {
newBlog.child("image_"+i+1).setValue(downloadUri[i]);
}
newBlog.child("location").setValue(location);
它存储除图像之外的所有值 .
将所有图像url存储在数据库中之后我应该如何获取所有图像，因为我不知道数据库中的图像数量，因此我无法获取一定数量的imageview？我怎么知道一个节点有多少子名“ïmages_1”，“images_2”？
logcat的 .

请尝试编辑上面的代码并尝试..
在将downloadUri传递给setvalue（）时，我忘了添加.toString . 这是造成overFlow异常的原因 .
有关详细信息，请参阅此问
PS . 我不知道为什么人们无法回答问题，如果他们无法回答它 .
