如何将具有多个数据的字符串添加到字符串数组 [英] How can i add a String with multiple data to String Array

问题描述

我想将MainActivity.java中 actorImages 中的字符串添加到另一个类中的 String [] getActorsUrls()中

i want to add the string from actorImages in MainActivity.java to String[] getActorsUrls() in another class

MainActivity.java

MainActivity.java

 DatabaseReference reference = FirebaseDatabase.getInstance().getReference();
    Query query = reference.child("actors").orderByChild("image");
    ValueEventListener valueEventListener = new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {

            for (DataSnapshot ds : dataSnapshot.getChildren()){
                String  actorImages = ds.child("image").getValue(String.class);

                Toast.makeText(MainActivity.this, actorImages, Toast.LENGTH_SHORT).show();
            }
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    };
    query.addListenerForSingleValueEvent(valueEventListener);

ImageUrlUtils.java

ImageUrlUtils.java

 public static String[] getActorsUrls() {
    String[] urls = new String[]{
            "string 1,
            "string 2",
    };
    return urls;
}

推荐答案

我认为您的网址有问题，请尝试:D

I think you have a problem on the urls, try this :D

ImageUrlUtils.java

 public static String[] getActorsUrls() {
    String[] urls = new String[]{
            "string 1",
            "string 2",
    };
    return urls;
}
