ExpandableListView: Get input values from childs
Add a new class SelectedDrink like this:
public class SelectedDrink {
String content;
int qty;
}
Then try this adapter code:
public class ExpandableListAdapterDrinks extends BaseExpandableListAdapter {

I test the above with this activity:
public class MainActivity extends AppCompatActivity {
final private static int NUM_OF_GROUP = 5;
List<Drink> drinksList;
ExpandableListView listView;
ExpandableListAdapterDrinks expandableListAdapterDrinks;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btRest = findViewById(R.id.btReset);
Button btOk = findViewById(R.id.btOK);
listView = findViewById(R.id.elvDrinks);
initDataList();
expandableListAdapterDrinks =
new ExpandableListAdapterDrinks(getApplicationContext(), drinksList, btRest, btOk);
listView.setAdapter(expandableListAdapterDrinks);
listView.expandGroup(0);
btRest.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
expandableListAdapterDrinks.resetTotalSum();
for(int i=0; i<drinksList.size(); i++) listView.collapseGroup(i);
listView.expandGroup(0);
}
});
btOk.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String msg = "Nothing Selected";
Button button = (Button)view;
if(!button.getText().equals("0")) {
msg = "Upload!\n";
ArrayList<SelectedDrink> selectedDrinks = expandableListAdapterDrinks.getOrderList();
for(SelectedDrink selectedDrink: selectedDrinks) {
msg += selectedDrink.content + " " + selectedDrink.qty + "\n";
}
msg += "Total: " + button.getText();
}
Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_LONG).show();
}
});
}
private void initDataList(){
drinksList = new ArrayList<>();
List<String> content;
List<Integer> pricelist;
List<String> bg;
for(int i=1; i<=NUM_OF_GROUP; i++) {
content = new ArrayList<>();
pricelist = new ArrayList<>();
bg = new ArrayList<>();
for(int j = 1; j<(NUM_OF_GROUP + new Random().nextInt(5)); j++){
content.add("Drink " + i + "-" + j);
pricelist.add(new Random().nextInt(1000));
bg.add("#008577");
bg.add("#D81B60");
}
Drink drink = new Drink();
drink.setTitle("Group " + i);
drink.setContent(content);
drink.setPricelist(pricelist);
drink.setBg(bg);
drinksList.add(drink);
}
}
}
and this layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<LinearLayout
android:id="@+id/llBtns"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal">
<Button
android:id="@+id/btReset"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:enabled="false"

<ExpandableListView
android:id="@+id/elvDrinks"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@id/llBtns">
</ExpandableListView>
</RelativeLayout>
Also, your Drink class, vip_package_listgroup.xml and vip_drinks_listitem.xml are also needed. Hope that helps!
ExpandableListView with multiple child in each row
Looks like you want to get GridView as items of expandable ListView. The following blog post seems pretty promising. Give it a try:
https://nishantsh.blogspot.com/2017/05/android-gridview-as-expandablelistview.html
Below is the content provided in the blog post:
- First of all make a custom gridView class named MyCustomGridView.java and add the following code snippet to it:
public class MyCustomGridView extends GridView {
private final Context mContext;
int mHeight;
public MyCustomGridView(Context context, AttributeSet attrs) {
super(context, attrs);
this.mContext = context;
}
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int desiredWidth = 100;
int widthMode = MeasureSpec.getMode(widthMeasureSpec);
int widthSize = MeasureSpec.getSize(widthMeasureSpec);
int width;
// Measure Width
if (widthMode == MeasureSpec.EXACTLY) {
// Must be this size
width = widthSize;
} else if (widthMode == MeasureSpec.AT_MOST) {
// Can't be bigger than...
width = Math.min(desiredWidth, widthSize);
} else { // Be whatever you want
width = desiredWidth;
}
// MUST CALL THIS
setMeasuredDimension(width, mHeight);
getGridViewSpanCount(width, mHeight);
}
public void setGridViewItemHeight(int height) {
mHeight = height;
}
}
- Now make the layout file named gridview_item.xml which will be used as item of GridView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="@+id/item_gridView_imgView"
android:layout_width="@dimen/dimen_img_width"
android:layout_height="@dimen/dimen_img_height"
android:scaleType="centerCrop" />
<TextView
android:id="@+id/item_gridView_txtView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="1"
android:textAlignment="center"
android:textColor="@color/black"
android:textSize="16sp" />
</RelativeLayout>
- Now make the adapter named MyCustomGridViewAdapter.java for setting the views in your gridView as follows:
public class MyCustomGridViewAdapter extends BaseAdapter {
private Context mContext;
private final ArrayList<YOUR_CLASS_TYPE> arrayList;
public MyCustomGridViewAdapter(Context context, ArrayList<YOUR_CLASS_TYPE> arrayList) {
this.mContext = context;
this.arrayList = arrayList;
}
@Override
public int getCount() {
return arrayList.size();
}
@Override
public YOUR_CLASS_TYPE getItem(int position) {
return arrayList.get(position);
}
@Override
public long getItemId(int arg0) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.gridview_item, parent, false);
holder = new ViewHolder();
holder.text = (TextView) convertView.findViewById(R.id.item_gridView_txtView);
holder.imageView = (ImageView) convertView.findViewById(R.id.item_gridView_imgView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.text.setText(arrayList.get(position).getName());
// Glide is the library used to laod an image into an imageView
Glide.with(mContext).load(arrayList.get(position).getThumbnail_url())
.asBitmap().centerCrop()
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.into(holder.imageView);
return convertView;
}
private static class ViewHolder {
TextView text;
ImageView imageView;
}
}
- Now create a Fragment named ExpandableListViewFragment.java and add the following code snippet:
public class ExpandableListViewFragment extends Fragment implements GridViewItemClickInterface {
private List<String> listDataHeader;
private HashMap<String, ArrayList<YOUR_CLASS_TYPE>> listDataChild;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.layout_fragment_expandable_listvw, container, false);
ExpandableListView mExpandablelistView = (ExpandableListView) rootView.findViewById(R.id.fragment_expandable_listview);
prepareListData();
CustomExpandableListAdapter mExpandableListAdapter = new CustomExpandableListAdapter(getActivity(), listDataHeader, listDataChild, this);
mExpandablelistView.setAdapter(mExpandableListAdapter);
mExpandablelistView.setOnGroupClickListener(new OnGroupClickListener() {
@Override
public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
// This way the expander cannot be collapsed
// on click event of group item
return false;
}
});
return rootView;
}
private void prepareListData() {
listDataHeader = new ArrayList<>();
listDataHeader.add("Folder 1");
listDataHeader.add("Folder 2");
listDataChild = new HashMap<>();
ArrayList<YOUR_CLASS_TYPE> details = new ArrayList<YOUR_CLASS_TYPE>();// fill the data as per your requirements
listDataChild.put(listDataHeader.get(0), details);
listDataChild.put(listDataHeader.get(1), null); // just to show null item view
}
@Override
public void onGridViewItemClick(YOUR_CLASS_TYPE item) {
Toast.makeText(getActivity(), "Currently selected is: " + item.getName(), Toast.LENGTH_SHORT).show();
}
}
- The layout file for the above fragment is as follows: layout_fragment_expandable_listvw.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ExpandableListView
android:id="@+id/fragment_expandable_listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@color/transparent"
android:listSelector="@color/transparent" />
</RelativeLayout>
</LinearLayout>
- Now create the adapter named CustomExpandableListAdapter.java file with the following code snippet:
public class CustomExpandableListAdapter extends BaseExpandableListAdapter {
private Context mContext;
private List<String> mListDataHeader;
private HashMap<String, ArrayList<YOUR_CLASS_TYPE>> mListDataChild;
private LayoutInflater mInflater;
private GridViewItemClickInterface gridViewItemClickListener;
private int columnsCount = 3;
public CustomExpandableListAdapter(Context context, List<String> listDataHeader, HashMap<String, ArrayList<YOUR_CLASS_TYPE>> listChildData, GridViewItemClickInterface listener) {
this.mContext = context;
this.mListDataHeader = listDataHeader;
this.mListDataChild = listChildData;
this.mInflater = LayoutInflater.from(context);
this.gridViewItemClickListener = listener;
}
@Override
public int getGroupCount() {
return mListDataHeader.size();
}
@Override
public int getChildrenCount(int groupPosition) {
return 1;
}
@Override
public Object getGroup(int groupPosition) {
return mListDataHeader.get(groupPosition);
}
@Override
public Object getChild(int groupPosition, int childPosition) {
return mListDataChild.get(this.mListDataHeader.get(groupPosition))
.size();
}
@Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
@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) {
// layout view of header group
convertView = mInflater.inflate(R.layout.expandable_listvw_header, null);
}
TextView headerLabel = (TextView) convertView.findViewById(R.id.txtView_header);
headerLabel.setTypeface(null, Typeface.BOLD);
headerLabel.setText(headerTitle);
return convertView;
}
@Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
convertView = mInflater.inflate(R.layout.expandable_listvw_item, null);
final ArrayList<YOUR_CLASS_TYPE> items = mListDataChild.get(mListDataHeader.get(groupPosition));
if (items.size() > 0) {
MyCustomGridView gridView = (MyCustomGridView) convertView.findViewById(R.id.item_custom_gridView);
gridView.setNumColumns(columnsCount);
gridView.setVerticalSpacing(10);
gridView.setHorizontalSpacing(10);
MyCustomGridViewAdapter adapter = new MyCustomGridViewAdapter(mContext, items);
gridView.setAdapter(adapter);
int totalHeight = 0;
// This is to get the actual size of gridView at runtime while filling the items into it
for (int size = 0; size < adapter.getCount(); size++) {
RelativeLayout relativeLayout = (RelativeLayout) adapter.getView(size, null, gridView);
relativeLayout.measure(0, 0);
totalHeight += relativeLayout.getMeasuredHeight();
}
gridView.setGridViewItemHeight(v);
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
gridViewItemClickListener.onGridViewItemClick(items.get(position));
}
});
} else {
convertView = mInflater.inflate(R.layout.layout_blank, null);
}
return convertView;
}
@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
}
- The layout files for ExpandableListView group and item are as follows:
a) expandable_listvw_header.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/txtView_header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="@color/colorBlack"
android:textSize="22sp" />
</LinearLayout>
b) expandable_listvw_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.nishant.sample.ExpandableListPac.MyCustomGridView
android:id="@+id/item_custom_gridView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
c) layout_blank.xml - This is the layout to be shown when no items are available.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="@+id/item_txt_no_items"
android:layout_width="match_parent"
android:layout_height="80dp"
android:gravity="center_horizontal|center_vertical"
android:text="No items available"
android:textSize="22sp" />
</LinearLayout>
- The interface class GridViewItemClickInterface.java is as follows:
public interface GridViewItemClickInterface {
void onGridViewItemClick(YOUR_CLASS_TYPE item);
}
