How can I get specific view from ExpandableListView? - java

I have created a expandable list view and two radio buttons in it.
I want to get the value of the radio button which is selected when some button is pressed in my main Activity. My ExpandableListView is working properly but i am not able to get the radio button which is selected in main activity.

Use onChildClick method in your code.This method is automatically called when you click on child item
#Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
//get your radio here from the view v and do whatever you want
return true;
}

Problem with an ExpandableList with 3 level

I have a problem with my ExpendableList. I am trying
to make a 3 level expandablelist. The display on the 3 levels works
fine and stays tidy as it should. But I don't know why, the
subcategories are duplicated. Here is the whole code with the adapter
and the creation of my HashMap. If you have an idea where this comes
from you would help me a lot!

EditText text is copying itself to another EditText field

Now when I change fields and open another Expandable List it change fields
My Expandable list Adapter
public class ExpandableListAdapter extends BaseExpandableListAdapter {
private static final String LOG_TAG = "EXPANDABLE_LIST_ADAPTER_LOG";
private Context _context;
private List<String> _listDataHeader; // header titles
// child data in format of header title, child title
private HashMap<String, List<String>> _listDataChild;
public ExpandableListAdapter(Context context, List<String> listDataHeader,
HashMap<String, List<String>> listChildData) {
this._context = context;
this._listDataHeader = listDataHeader;
this._listDataChild = listChildData;
Log.i(LOG_TAG,"Child:"+listChildData+" header:"+listDataHeader);
}
#Override
public Object getChild(int groupPosition, int childPosititon) {
Object obj = this._listDataChild.get(this._listDataHeader.get(groupPosition))
.get(childPosititon);
Log.i(LOG_TAG,"GroupPos:"+groupPosition+" childPos:"+childPosititon+" EdTex:"+obj);
return obj;
}
#Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
#Override
public View getChildView(int groupPosition, final int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
final String childText = (String) getChild(groupPosition, childPosition);
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) this._context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.list_item, null);
}
EditText txtListChild = (EditText) convertView
.findViewById(R.id.lblListItem);
// txtListChild.setText(childText);
txtListChild.setHint(childText);
Log.i(LOG_TAG,"GroupPos:"+groupPosition+" childPos:"+childPosition+" text:"+txtListChild.getText());
return convertView;
}
#Override
public int getChildrenCount(int groupPosition) {
String groupS = this._listDataHeader.get(groupPosition);
int size =this._listDataChild.get(groupS)
.size();
Log.i(LOG_TAG,"Group:"+groupS+" grouppos:"+groupPosition+" size:"+size );
return size;
}
#Override
public Object getGroup(int groupPosition) {
return this._listDataHeader.get(groupPosition);
}
#Override
public int getGroupCount() {
return this._listDataHeader.size();
}
#Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
#Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
String headerTitle = (String) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) this._context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.list_group, null);
}
TextView lblListHeader = (TextView) convertView
.findViewById(R.id.lblListHeader);
lblListHeader.setTypeface(null, Typeface.BOLD);
lblListHeader.setText(headerTitle);
return convertView;
}
#Override
public boolean hasStableIds() {
return true;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
}
Also I realize that when keyboard is on, it deletes fields, or make it disappear like if it was creating another instance of EditTexts.
The first problem got fixed by setting stable ids to true, I found that might be useful if anyone willing to associate the problems
#Override
public boolean hasStableIds() {
return true;
}

how to get all the child id in an ExpandableListView without depending on the parent group

I've designed a GUI with an ExpandableListView, please see sample picture below.
I want to know if it is possible to get the IDs of all the child in the list without having to depend on the parent group.
Presently what I'm able to get is 0-2 for the first Parent and the second parent also starts from 0.
So basically I want to get the IDs like:
Fixture ? id(0)
Chillers ? id(1)
Displays ? id(2)
"33" Export (Can) id(3)
etc.
Here my Custom adapter class:
public class MTOExpandableListAdapter extends BaseExpandableListAdapter {
private Context _context;
private List<String> _listDataHeader; // header titles
// child data in format of header title, child title
private HashMap<String, List<String>> _listDataChild;
public MTOExpandableListAdapter(Context context, List<String> listDataHeader, HashMap<String, List<String>> listChildData) {
this._context = context;
this._listDataHeader = listDataHeader;
this._listDataChild = listChildData;
}
#Override
public int getGroupCount() {
return this._listDataHeader.size();
}
#Override
public int getChildrenCount(int groupPosition) {
return this._listDataChild.get(this._listDataHeader.get(groupPosition)).size();
}
#Override
public Object getGroup(int groupPosition) {
return this._listDataHeader.get(groupPosition);
}
#Override
public Object getChild(int groupPosition, int childPosition) {
return this._listDataChild.get(this._listDataHeader.get(groupPosition)).get(childPosition);
}
#Override
public long getGroupId(int childPosition) {
return childPosition;
}
#Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
#Override
public boolean hasStableIds() {
return false;
}
#Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
String headerTitle = (String) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) this._context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.list_mto_group, null);
}
TextView lblListHeader = (TextView) convertView.findViewById(R.id.lblListHeader);
lblListHeader.setTypeface(null, Typeface.BOLD);
lblListHeader.setText(headerTitle);
return convertView;
}
#Override
public View getChildView(int groupPosition, final int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
final String childText = (String) getChild(groupPosition, childPosition);
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) this._context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.list_mto_item, null);
}
TextView txtListChild = (TextView) convertView.findViewById(R.id.lblMTOListItem);
txtListChild.setText(childText);
return convertView;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
}
Okay, I see what you are asking. You are trying to get a unique ID for every child of every group, in numerical order.
#Override
public long getChildId(int groupPosition, int childPosition) {
int id = 0;
for (int group = 0; group < groupPosition; group++) {
id += getChildrenCount(group);
}
id += childPosition;
return id;
}

How to update Android ExpandableList data dynamically?

I have a ExpandableListView in a Fragment.
I'm posting a request to the server using RoboSpice onCreateView.
I want to be able to update the list twice, once when I get the data from the cache and second after the response returns.
For some reason the list is not populated.
I was able to populate it when I instantiate a new adapter and set the adapter for list, but for some reason it doesn't work on some android devices.
This is the code I'm using:
Fragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
_expandableListAdapter = new GroupsExpandableListAdapter(getActivity(), getSpiceManager());
_groupListView.setAdapter(_expandableListAdapter);
DBServerHelper.Groups.getByBusinessId(getActivity(), getSpiceManager(), getDBHelper(), _clientBusiness.getId(),
new CachedRequestListener<ClientGroup.List>(getDBHelper(), getActivity()) {
#Override
// This method runs twice, after the data comes from the cache and once the request succeed
public void onRequestFromCache(ClientGroup.List clientGroups) {
if (clientGroups == null || clientGroups.isEmpty()) {
Ln.d("Received clientGroups " + clientGroups == null ? "null" : "empty" + " form request GetByBusinessId");
return;
}
_expandableListAdapter.clear();
_expandableListAdapter.setGroups(clientGroups);
_expandableListAdapter.notifyDataSetChanged();
_groupListView.invalidateViews();
}
#Override
public void onRequestFailure(SpiceException spiceException) {
super.onRequestFailure(spiceException);
Ln.e(spiceException, "Failed to get groups ");
Toaster.showLong(getActivity(), "Could not get businesses groups: " + spiceException.getMessage());
}
});
}

((ImageView) v.findViewById(R.id.groupIndicator))
.setImageResource(isExpanded ? R.drawable.arrow_up_turquoise : R.drawable.arrow_down_white);
} else {

}
return v;
}
#Override

View v;
if (convertView == null) {
LayoutInflater li = (LayoutInflater) _activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = li.inflate(R.layout.group_list_child, parent, false);
} else {

}
TextView joinGroupButton = (TextView) v.findViewById(R.id.joinGroupButton);
final ClientGroup group = _data.get(groupPosition);
String leaveGroupStr = _activity.getString(R.string.leave_group);
String joinGroupStr = _activity.getString(R.string.join_group);
return v;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return false;

}
Any suggestions?
Thanks!

Android Expandable List - OnClickListener

I'm having trouble with setting an OnClickListener to list items in my ExpandableListActivity. The code structure matches the following example:
ExpandableListAdapter mAdapter;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Assign the adapter
mAdapter = new MyExpandableListAdapter();
setListAdapter(mAdapter);
}
public class MyExpandableListAdapter extends BaseExpandableListAdapter {
private String[] groups = { "foo", "bar"};
private String[][] children = {
{"fooA", "barA"},
{"fooB", "barB"}
};
public Object getChild(int groupPosition, int childPosition) {
return children[groupPosition][childPosition];
}
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
public int getChildrenCount(int groupPosition) {
return children[groupPosition].length;
}
public TextView getGenericView() {
// Layout parameters for the ExpandableListView
AbsListView.LayoutParams lp = new AbsListView.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT, 64);
TextView textView = new TextView(Calculations.this);
textView.setLayoutParams(lp);
// Center the text vertically
textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.LEFT);
// Set the text starting position
textView.setPadding(64, 0, 0, 0);
return textView;
}
public View getChildView(int groupPosition, int childPosition, boolean isLastChild,
View convertView, ViewGroup parent) {
TextView textView = getGenericView();
textView.setText(getChild(groupPosition, childPosition).toString());
textView.setPadding(98, 0, 0, 0);
return textView;
}
public Object getGroup(int groupPosition) {
return groups[groupPosition];
}
public int getGroupCount() {
return groups.length;
}
public long getGroupId(int groupPosition) {
return groupPosition;
}
public View getGroupView(int groupPosition, boolean isExpanded, View convertView,
ViewGroup parent) {
TextView textView = getGenericView();
textView.setText(getGroup(groupPosition).toString());
return textView;
}
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
public boolean hasStableIds() {
return true;
}
}
Once I'm able to set the listener, I'll most likely do something like this:
// Listener
{
switch(groupPosition) {
case 0:
switch(childPosition) {
case 0:
selected = 00;
return true;
}
}
}// Close listener
Please tell me if I'm not being clear enough.
You should override onChildClick() in your activity.
boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id)
Override this for receiving callbacks when a child has been clicked.
