Android从parse.com中检索图像和文本并在适配器中使用它

Question

实际上，我想使用此库“Aphid-FlipView-Library”来执行翻动动画。我想翻转的图像和文本来自Parse.com。我已经可以通过使用下面的方式翻转图像。

这是代码。前半部分活动中，我将从parse.com检索的图像添加到名为notes的数组列表中，并将其用于适配器中。

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.rotate); 
    FlipViewController flipView = new FlipViewController(this, FlipViewController.HORIZONTAL); 
    final NoteViewAdapter mAdapter = new NoteViewAdapter(this); 
    flipView.setAdapter(mAdapter); 
    setContentView(flipView); 
    final ArrayList<Bitmap> notes = new ArrayList<Bitmap>(); 
    @@@final ArrayList<String> texts = new ArrayList<String>();@@@ 

    ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("Card"); 
    query.getInBackground("wxYBHhRlhZ", new GetCallback<ParseObject>() { 

     @Override 
     public void done(ParseObject object, ParseException e) { 
     if(e == null){ 
      ParseFile fileObject1 = (ParseFile) object.get("Photoin1"); 
      fileObject1.getDataInBackground(new GetDataCallback(){ 

       @Override 
       public void done(byte[] data, ParseException e) { 
        notes.add(BitmapFactory.decodeByteArray(data,0,data.length)); 
        mAdapter.setNotes(notes); 
       } 
      }); 
      @@@String playerName = object.getString("Textin1");@@@ 
      @@@texts.add(playerName);@@@ 
      @@@mAdapter.setTexts(texts);@@@ 
     }else{ 
      //nothing 
     } 
     } 
    });  
} 

然后，下面显示了作为适配器的后半部分活动。

public class NoteViewAdapter extends BaseAdapter { 
    private LayoutInflater inflater;   
    private ArrayList<Bitmap> notes; 
    @@@private ArrayList<String> texts;@@@  

    public NoteViewAdapter(Context currentContext) { 
     inflater = LayoutInflater.from(currentContext);   
    } 

    @Override 
    public int getCount() { 
     return notes == null ? 0 : notes.size() 
    } 

    @Override 
    public Object getItem(int position) { 
     return position; 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    public void setNotes(ArrayList notes) { 
     this.notes = notes; 
     notifyDataSetChanged(); 
    } 
    @@@public void setTexts(ArrayList texts) {@@@ 
    @@@ this.texts = texts;    @@@ 
    @@@ notifyDataSetChanged();   @@@ 
    @@@}          @@@ 
    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View layout = convertView; 

     if (convertView == null) { 
      layout = inflater.inflate(R.layout.rotate, null); 
     }    


     Bitmap note = notes.get(position); 
     @@@String text = texts.get(position);@@@ 

     ImageView tView = (ImageView) layout.findViewById(R.id.picture); 
     @@@TextView view = (TextView) layout.findViewById(R.id.text);@@@ 

     tView.setImageBitmap(note); 
     @@@view.setText(text);@@@ 

     return layout; 
    } 
} 

我可以告诉already.I希望通过使用相同的方式来显示的图像附近的文本图像，但我得到了错误后，我补充一点，在召开的代码@@@和@@@ 。请帮我说清楚。

Answer 1

的调节器，texts应该是一个ArrayList<String>，不是ArrayList<Bitmap>。我不知道这是否修复，但肯定是一个问题。
