[英]Store Multiple pictures in Firebase Storage
问题描述
I have a code for storing images in the firebase storage but it only storing one image at a time and I need to Store multiple images Here's the code: 
我有一个用于在Firebase存储器中存储图像的代码，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();
}
}
});
}
The code look long but is only much of the same. 该代码看起来很长，但是几乎没有什么不同。 I try repeating the method depending on what the user do if he select only two images it should save those two at once and if he select tree it should save those 3 and so on... 我尝试根据用户的操作重复该方法，如果用户只选择两个图像，则应一次保存这两个图像，如果他选择树，则应保存这三个图像，依此类推...

Did you see that your code is actually duplicated? 您是否看到您的代码实际上是重复的？
Wrap your code in a function like this: 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();
}
}
});
}
Now use can use it directly: 现在使用可以直接使用它：
storeImage(imageUri);
or make use of multiple store: 或利用多个商店：
public void storeMultipleImages(List<Uri> imageUris) {
for (Uri uri : imageUris) {
storeImage(uri);
}
}
There you can store any number of images with the code 您可以在其中使用代码存储任意数量的图像
