Question

我有一个聊天应用程序，我正在寻找一种方法来隐藏聊天的个人资料图像，当同一个人有两个或更多连续聊天时，我该怎么办？或者可能使用不同的聊天泡泡，如Facebook或其他聊天应用

以下是我所拥有的样本，

   private static class ChatCursorAdapter extends CursorAdapter {

    private ChatCursor chatCursor;

        public ChatCursorAdapter(Context context, CommentsCursor cursor) {
            super(context, cursor, 0);
        chatCursor = cursor;
        }

        @Override
        public View newView(Context context, Cursor cursor, ViewGroup parent) {

            LayoutInflater inflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            return inflater.inflate(R.layout.chat_layout, parent, false);
        }


    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        ImageView imgView = (ImageView) view.findViewById(R.id.imageView1);
        Chat chat = chatCursor.getChat();   
        //If the previous chat was from the same 
        //person set the profile image to invisible
    }


}

如果我理解正确，这可以帮到你。

@Override
public View newView(View view, Context context, Cursor cursor) {
    int posBeforeLast = cursor.getCount() - 1;
       //Also can use to check current position of the cursor
    int currentPostion= cursor.getPosition();
}
