将多个图像上传到Firebase存储 [英] Upload multiple images to firebase storage

问题描述

我使用firebase构建聊天应用程序，并且希望将多个图像发送到firebase存储.

i build a chat application using firebase and i want to send multiple image to firebase storage.

使用此库

编译'com.github.darsh2:MultipleImageSelect:3474549'

compile 'com.github.darsh2:MultipleImageSelect:3474549'

在顶部

private StorageReference storageRef;
private FirebaseApp app;
private FirebaseStorage storage;

onCreate()方法

onCreate()Method

app = FirebaseApp.getInstance();
storage =FirebaseStorage.getInstance(app);

按钮点击操作

   Gallary.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                Intent intent = new Intent(ChatActivity.this, AlbumSelectActivity.class);
                intent.putExtra(Constants.INTENT_EXTRA_LIMIT, 10);
                startActivityForResult(intent, Constants.REQUEST_CODE);
                pwindo1.dismiss();
            }
        });

活动结果

    if (requestCode == Constants.REQUEST_CODE && resultCode == RESULT_OK) {
        ArrayList<Image> images = data.getParcelableArrayListExtra(Constants.INTENT_EXTRA_IMAGES);
        Uri uri = Uri.parse(String.valueOf(images));
        storageRef = storage.getReference("photos");
        final StorageReference photoRef = storageRef.child(uri.getLastPathSegment());
        photoRef.putFile(uri)
                .addOnSuccessListener(this, new OnSuccessListener<UploadTask.TaskSnapshot>() {
                    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                        Uri downloadUrl = taskSnapshot.getDownloadUrl();
                        String content = downloadUrl.toString();
                        if (content.length() > 0) {
                            editWriteMessage.setText("");
                            Message newMessage = new Message();
                            newMessage.text = content;
                            newMessage.idSender = StaticConfig.UID;
                            newMessage.idReceiver = roomId;
                            newMessage.timestamp = System.currentTimeMillis();
                            FirebaseDatabase.getInstance().getReference().child("message/" + roomId).push().setValue(newMessage);
                        }
                    }
                });

    }

推荐答案

工作正常.

 if (requestCode == Constants.REQUEST_CODE && resultCode == RESULT_OK) {
        ArrayList<Image> images = data.getParcelableArrayListExtra(Constants.INTENT_EXTRA_IMAGES);
        Uri[] uri=new Uri[images.size()];
        for (int i =0 ; i < images.size(); i++) {
            uri[i] = Uri.parse("file://"+images.get(i).path);
            storageRef = storage.getReference("photos");
            final StorageReference ref = storageRef.child(uri[i].getLastPathSegment());
            ref.putFile(uri[i])
                    .addOnSuccessListener(this, new OnSuccessListener<UploadTask.TaskSnapshot>() {
                        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                            Uri downloadUrl = taskSnapshot.getDownloadUrl();
                            String content = downloadUrl.toString();
                            if (content.length() > 0) {
                                editWriteMessage.setText("");
                                Message newMessage = new Message();
                                newMessage.text = content;
                                newMessage.idSender = StaticConfig.UID;
                                newMessage.idReceiver = roomId;
                                newMessage.timestamp = System.currentTimeMillis();
                                FirebaseDatabase.getInstance().getReference().child("message/" + roomId).push().setValue(newMessage);
                            }
                        }
                    });

        }

    }
