android firebase storage在列表視圖中檢索

Question

假設我在Firebase存儲中有5個音頻文件，並且我想要檢索這5個音頻文件並將它們顯示在列表視圖中。當我點擊5個文件中的任何一個時，它們應該被下載到本地手機內存中？

獲取對你的refernece.then的5首歌曲的列表中添加該列表適配器

  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) { 

     } 


    });
