如何獲取下載URI？String downloadThumbUri = uploadTask.getResult().getStorage().getDownloadUrl().toString();不管用。我正在使用位圖來壓縮圖像以將其用作縮略圖。這是代碼：ByteArrayOutputStream baos = new ByteArrayOutputStream();compressedImageFile.compress(Bitmap.CompressFormat.JPEG, 100, baos);byte[] thumbData = baos.toByteArray();final UploadTask uploadTask = storageReference.child("post_images/thumbs").child(randomName + ".jpg").putBytes(thumbData);uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() { @Override public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) { //Toast.makeText(NewPostActivity.this,"Thumbnail was uploaded ",Toast.LENGTH_LONG).show(); String downloadThumbUri = uploadTask.getResult().getStorage().getDownloadUrl().toString(); Map<String,Object> postMap = new HashMap<>(); postMap.put("image url",downloadUri); postMap.put("thumb",downloadThumbUri); postMap.put("desc",desc); postMap.put("user_id",current_user_id); postMap.put("timestamp",FieldValue.serverTimestamp()); firebaseFirestore.collection("Posts").add(postMap).addOnCompleteListener(new OnCompleteListener<DocumentReference>() { @Override public void onComplete(@NonNull Task<DocumentReference> task) { if(task.isSuccessful()){ newPostProgress.setVisibility(View.INVISIBLE); Toast.makeText(NewPostActivity.this,"Post was added ",Toast.LENGTH_LONG).show(); Intent mainIntent = new Intent(NewPostActivity.this,MainActivity.class); startActivity(mainIntent); finish(); } } }) }}

使用以下代碼獲取下載 uri 并存儲在 Firestore 中。把它放在onSucess里面
uploadTask.getDownloadUrl().addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
String downloadThumbUri = task.getResult().toString();
Map<String,Object> postMap = new HashMap<>();
postMap.put("image url",downloadUri);
postMap.put("thumb",downloadThumbUri);
postMap.put("desc",desc);
postMap.put("user_id",current_user_id);
postMap.put("timestamp",FieldValue.serverTimestamp());
firebaseFirestore.collection("Posts").add(postMap).addOnCompleteListener(new OnCompleteListener<DocumentReference>() {
@Override
public void onComplete(@NonNull Task<DocumentReference> task) {
if(task.isSuccessful()){
newPostProgress.setVisibility(View.INVISIBLE);
Toast.makeText(NewPostActivity.this,"Post was added ",Toast.LENGTH_LONG).show();
Intent mainIntent = new Intent(NewPostActivity.this,MainActivity.class);
startActivity(mainIntent);
finish();
}
});
}
})
.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
progressBar.setVisibility(View.GONE);
Toast.makeText(ProfileActivity.this, "aaa "+e.getMessage(), Toast.LENGTH_SHORT).show();
}
});
