android firebase storage在列表视图中检索

Question

假设我在Firebase存储中有5个音频文件，并且我想要检索这5个音频文件并将它们显示在列表视图中。当我点击5个文件中的任何一个时，它们应该被下载到本地手机内存中？

获取对你的refernece.then的5首歌曲的列表中添加该列表适配器

  your_ref.addListenerForSingleValueEvent(new ValueEventListener()  { 
      @Override 
      public void onDataChange(DataSnapshot dataSnapshot) { 


      songslist= new ArrayList<String>(); 

      Toast.makeText(DataFromFirebase.this, "number of songs are " + dataSnapshot.getChildrenCount(), Toast.LENGTH_LONG).show(); 
      //String value = (String) dataSnapshot.getValue(); 
       sizetemp=dataSnapshot.getChildrenCount(); 
      // Result will be holded Here 
      for (DataSnapshot dsp : dataSnapshot.getChildren()) { 
       songslist.add(String.valueOf(dsp.getKey())); //add result into array list 

      //NOW YOU HAVE ARRAYLIST WHICH HOLD RESULTS 




     } 

     @Override 
     public void onCancelled(DatabaseError firebaseError) { 

     } 


    });
