java - 在 Firebase 存储中存储多张图片

Question

我有一个用于在 firebase 存储中存储图像的代码，但它一次只能存储一个图像，我需要存储多个图像这是代码:

 Save.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Saveimages();
        }
    });

}

private void Saveimages() {

    comment = Comment.getText().toString();

    if (imageUri==null||imageUri2==null){
        Toast.makeText(this, "...Select a Image...", Toast.LENGTH_SHORT).show();
    }
    else if(imageUri!=null&&imageUri2!=null&&imageUri3==null&&imageUri4==null) {
        Save2ImagesFirebase();
    }
    else if(imageUri!=null&&imageUri2!=null&&imageUri3!=null&&imageUri4==null){
        Save3ImagesFirebase();
    }
    else if(imageUri!=null&&imageUri2!=null&&imageUri3!=null&&imageUri4!=null){
        Save4ImagesFirebase();
    }
}


private void Save2ImagesFirebase() {


    StorageReference filepath = mStorage.child(" Images");
    filepath.putFile(imageUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

            if (task.isSuccessful()){

                Toast.makeText(ImageVersus.this, " Published", Toast.LENGTH_SHORT).show();

            }
            else{
                Toast.makeText(ImageVersus.this, "..Error..", Toast.LENGTH_SHORT).show();
            }

        }
    });

    StorageReference filepath2 = mStorage.child(" Images");
    filepath2.putFile(imageUri2).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

            if (task.isSuccessful()){

                Toast.makeText(ImageVersus.this, " Published", Toast.LENGTH_SHORT).show();

            }
            else{
                Toast.makeText(ImageVersus.this, "..Error..", Toast.LENGTH_SHORT).show();
            }

        }
    });

}

private void Save3ImagesFirebase() {

    StorageReference filepath = mStorage.child(" Images");
    filepath.putFile(imageUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

            if (task.isSuccessful()){

                Toast.makeText(ImageVersus.this, " Published", Toast.LENGTH_SHORT).show();

            }
            else{
                Toast.makeText(ImageVersus.this, "..Error..", Toast.LENGTH_SHORT).show();
            }

        }
    });

    StorageReference filepath2 = mStorage.child(" Images");
    filepath2.putFile(imageUri2).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

            if (task.isSuccessful()){

                Toast.makeText(ImageVersus.this, " Published", Toast.LENGTH_SHORT).show();

            }
            else{
                Toast.makeText(ImageVersus.this, "..Error..", Toast.LENGTH_SHORT).show();
            }

        }
    });

    StorageReference filepath3 = mStorage.child(" Images");
    filepath3.putFile(imageUri3).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

            if (task.isSuccessful()){

                Toast.makeText(ImageVersus.this, " Published", Toast.LENGTH_SHORT).show();

            }
            else{
                Toast.makeText(ImageVersus.this, "..Error..", Toast.LENGTH_SHORT).show();
            }

        }
    });

}

private void Save4ImagesFirebase() {

    StorageReference filepath = mStorage.child(" Images");
    filepath.putFile(imageUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

            if (task.isSuccessful()){

                Toast.makeText(ImageVersus.this, " Published", Toast.LENGTH_SHORT).show();

            }
            else{
                Toast.makeText(ImageVersus.this, "..Error..", Toast.LENGTH_SHORT).show();
            }

        }
    });

    StorageReference filepath2 = mStorage.child(" Images");
    filepath2.putFile(imageUri2).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

            if (task.isSuccessful()){

                Toast.makeText(ImageVersus.this, " Published", Toast.LENGTH_SHORT).show();

            }
            else{
                Toast.makeText(ImageVersus.this, "..Error..", Toast.LENGTH_SHORT).show();
            }

        }
    });

    StorageReference filepath3 = mStorage.child(" Images");
    filepath3.putFile(imageUri3).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

            if (task.isSuccessful()){

                Toast.makeText(ImageVersus.this, " Published", Toast.LENGTH_SHORT).show();

            }
            else{
                Toast.makeText(ImageVersus.this, "..Error..", Toast.LENGTH_SHORT).show();
            }

        }
    });

    StorageReference filepath4 = mStorage.child(" Images");
    filepath4.putFile(imageUri4).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

            if (task.isSuccessful()){

                Toast.makeText(ImageVersus.this, " Published", Toast.LENGTH_SHORT).show();

            }
            else{
                Toast.makeText(ImageVersus.this, "..Error..", Toast.LENGTH_SHORT).show();
            }

        }
    });

}

代码看起来很长，但只是大部分相同。我尝试根据用户的操作重复该方法，如果他只选择两个图像，它应该一次保存这两个，如果他选择树，它应该保存这 3 个，依此类推......

您是否看到您的代码实际上是重复的？

将您的代码包装在这样的函数中:

public void storeImage(Uri imageUri) {
    StorageReference filepath = mStorage.child(" Images");
    filepath.putFile(imageUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

            if (task.isSuccessful()){

                Toast.makeText(ImageVersus.this, " Published", Toast.LENGTH_SHORT).show();

            }
            else{
                Toast.makeText(ImageVersus.this, "..Error..", Toast.LENGTH_SHORT).show();
            }

        }
    });

}

现在可以直接使用了:

storeImage(imageUri);

或使用多个商店:

public void storeMultipleImages(List<Uri> imageUris) {
    for (Uri uri : imageUris) {
        storeImage(uri);
    }
}

在那里你可以用代码存储任意数量的图像
