[英]android AutoCompleteTextView seems to ignore the Filter of the custom ArrayAdapter
All I want to do is displaying a CheckBox at each result of the AutoCompleteTextView's results (which are strings). 我要做的就是在AutoCompleteTextView结果的每个结果(是字符串)上显示一个CheckBox。
I wrote an custom Array Adapter which implements Filterable. 我写了一个实现Filterable的自定义数组适配器。 I added a simple Filter wich gets called (I checked that) and returns the expected results.
我添加了一个简单的过滤器,该过滤器被调用(我检查了)并返回了预期的结果。 However the displayed results are completely different ones.
但是,显示的结果完全不同。
Here is my Filter-Code: 这是我的过滤器代码:
private class MyFilter extends Filter
{
@Override
protected FilterResults performFiltering(CharSequence constraint)
{
FilterResults results = new FilterResults();
if ((constraint == null) || (constraint.length() == 0))
{
synchronized (mLock)
{
ArrayList<String> list = new ArrayList<String>();
results.values = list;
results.count = list.size();
}
}
else
{
String constr = constraint.toString().toLowerCase();
final ArrayList<String> newItems = new ArrayList<String>();
for (String temp : items)
{
if (temp.toLowerCase().startsWith((constr)))
{
newItems.add(temp);
}
}
results.values = newItems;
results.count = newItems.size();
}
return results;
}
@Override
protected void publishResults(CharSequence constraint,
FilterResults results)
{
if (results.count > 0)
{
notifyDataSetChanged();
}
else
{
notifyDataSetInvalidated();
}
}
}
Do I miss something? 我想念什么吗? Thank you!
谢谢!
我忘记将结果设置为适配器的新项目。
