android imageview 回收,android-ViewHolder ImageView setVisibility重复

我有一个带有ViewHolder模式的适配器.它具有一个TextView和一个ImageView.我必须对适配器中的数据库进行一些检查,以显示或不显示ImageView.

问题是将View.VISIBLE的可见性也设置为其他位置的ImageView.我确定我的数据库不包含那些与那些imageview相关的数据,而只包含那些正确设置的数据.

这是我的代码(我删除了textview集合的一部分,因为它运作良好)：

public class ChaptersAdapter extends ArrayAdapter {

private final Context context;

private final ArrayList list;

ViewHolder viewHolder;

DatabaseHandler dh;

SQLiteDatabase db;

ArrayList bookmarksAL;

public ChaptersAdapter(Context context, ArrayList list) {

super(context, R.layout.chaptersadapter, list);

this.context = context;

this.list = list;

}

static class ViewHolder{

TextView titolo;

ImageView imageView;

}

@Override

public View getView(int position, View rowView, ViewGroup parent) {

dh = new DatabaseHandler(context);

db = dh.getWritableDatabase();

bookmarksAL = dh.getAllBookmarks(db);

List chapters = getItem(position);

if(rowView==null){

LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

rowView = inflater.inflate(R.layout.chaptersadapter, parent, false);

viewHolder = new ViewHolder();

viewHolder.titolo = (TextView) rowView.findViewById(R.id.textView);

viewHolder.imageView = (ImageView) rowView.findViewById(R.id.imageView);

rowView.setTag(viewHolder);

}

else {

viewHolder = (ViewHolder) rowView.getTag();

}

for(int i = 0; i

if(bookmarksAL.get(i).getId_chapter().equals((String)chapters.get(3))){

viewHolder.imageView.setVisibility(View.VISIBLE);

}

}

return rowView;

}

}

这是我的意思的屏幕：

只需要添加带圆圈的imageview,而不是上面带有X的imageview.如果我向下滚动列表视图,则视图持有者会将可见性设置为对不在数据库中的其他图像视图也可见.
