Outcome:
In this scenario, the AutoCompleteTextView in the parent group and the green plus button should be "selectable" so that the user can input the info into the field and click that button without collapsing the group. And the CheckBox and the red x button in the child should also be "selectable" so the user can check the CheckBox and click the button. The only part of that that actually works is that the CheckBox is selectable and the group doesn't collapse because for lack of a better term, the group layout is "dead" and does nothing when pressed. And the seemingly "working" CheckBox isn't even so because it does this weird thing where checking or unchecking one will randomly check or uncheck others.
回答1:
Below code is to resolve checkbox problem "CheckBox isn't even so because it does this weird thing where checking or unchecking one will randomly check or uncheck others." Along with ImageButton and CheckBox handling.
public override View GetChildView(final int groupPosition, int childPosition, bool isLastChild, View convertView, ViewGroup parent)
{
LayoutInflater inflater = (LayoutInflater)_context.GetSystemService(Context.LayoutInflaterService);
convertView = inflater.Inflate(Resource.Layout.transferAvailAttached, null);
E e = (E)GetChild(groupPosition, childPosition);
TextView serial = (TextView)convertView.FindViewById(Resource.Id.availSerial);
serial.Text = e.Serial;
TextView model = (TextView)convertView.FindViewById(Resource.Id.availModel);
model.Text = e.Model;
CheckBox include = (CheckBox)convertView.FindViewById(Resource.Id.include);
include.setOnCheckedChangeListener(new OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
//DO your checkbox handling here
}
});
ImageButton removeAttachment =(CheckBox)convertView.FindViewById(Resource.Id. removeAttachment);
removeAttachment.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
//DO your imageButton handling here
}
});
return convertView;
}
public override View GetGroupView(final int groupPosition, bool isExpanded, View convertview, ViewGroup parent)
{
View convertView = convertview;
if (convertView == null)
{
E e = (E)GetGroup(groupPosition);
LayoutInflater inflater = (LayoutInflater)_context.GetSystemService(Context.LayoutInflaterService);
convertView = inflater.Inflate(Resource.Layout.transferAvailPowered, null);
}
TextView serial = (TextView)convertView.FindViewById(Resource.Id.availSerial);
serial.Text = e.Serial;
TextView model = (TextView)convertView.FindViewById(Resource.Id.availModel);
model.Text = e.Model;
AutoCompleteTextView acText = (AutoCompleteTextView)convertView.FindViewById(Resource.Id.availSite);
acText.Adapter = _adapter;
ImageButton addToTransfer =(CheckBox)convertView.FindViewById(Resource.Id. addToTransfer);
addToTransfer.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
//DO your addToTransfer imageButton handling here
}
});
_list.ExpandGroup(groupPosition);
return convertView;
}
