    <p>I am using BaseExpandableListAdapter for displaying data is expandable list view. I have a scenario where I have to pop and push childs in groups. But unfortunately getchild method is calling two times for each child so I can not remove them because it give index out of range exception. Am I missing any thing important?</p> <pre><code>import android.content.Context; import android.graphics.Typeface; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseExpandableListAdapter; import android.widget.EditText; import android.widget.TextView; public class adpFolderWithTaskDone extends BaseExpandableListAdapter { private Context _context; private List&lt;clsTaskDoneDates&gt; _listDataHeader; // header titles SimpleDateFormat dateFormat1 = new SimpleDateFormat("EEE MMM dd"); SimpleDateFormat dateFormat2 = new SimpleDateFormat("HH:mm"); // child data in format of header title, child title private HashMap&lt;clsTaskDoneDates, List&lt;clsTasks&gt;&gt; _listDataChild; int i=0; int j=0; public ArrayList&lt;View&gt; ChildIds=new ArrayList&lt;View&gt;(); Typeface tf ; public adpFolderWithTaskDone(Context context, List&lt;clsTaskDoneDates&gt; listDataHeader, HashMap&lt;clsTaskDoneDates, List&lt;clsTasks&gt;&gt; listChildData) { this._context = context; this._listDataHeader = listDataHeader; this._listDataChild = listChildData; tf = Typeface.createFromAsset(context.getApplicationContext().getAssets(), "font/HelveticaNeueLTStd-LtEx.otf"); } @Override public Object getChild(int groupPosition, int childPosititon) { return this._listDataChild.get(this._listDataHeader.get(groupPosition)) .get(childPosititon); } @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 clsTasks childText = (clsTasks) getChild(groupPosition, childPosition); if (convertView == null) { LayoutInflater infalInflater = (LayoutInflater) this._context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = infalInflater.inflate(R.layout.list_tasks_done, null); } TextView txtListChild = (TextView) convertView .findViewById(R.id.lblListItemDone); txtListChild.setText(childText.getDescription()); EditText txtTaskId = (EditText) convertView .findViewById(R.id.TaskIdDone); txtTaskId.setText(Integer.toString(childText.getTaskId())); TextView lblTaskTime = (TextView) convertView.findViewById(R.id.lblTaskDueTimeDone); if (childText.getTaskDate()==null) { //lblTaskTime.setText("Today"); } else { lblTaskTime.setText( dateFormat1.format(childText.getTaskDate()) + " at " + dateFormat2.format(childText.getTaskDate()) ); } if(ChildIds.contains(convertView)==false) { ChildIds.add(convertView); } txtListChild.setTypeface(tf, Typeface.NORMAL); lblTaskTime.setTypeface(tf, Typeface.NORMAL); return convertView; } @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 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) { clsTaskDoneDates headerTitle = (clsTaskDoneDates) getGroup(groupPosition); if (convertView == null) { LayoutInflater infalInflater = (LayoutInflater) this._context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = infalInflater.inflate(R.layout.list_folder_done, null); } TextView lblListHeader = (TextView) convertView .findViewById(R.id.folderNameDone); lblListHeader.setTypeface(tf, Typeface.NORMAL); lblListHeader.setText(dateFormat1.format(headerTitle.getTaskDate())); TextView lblFolderId = (TextView) convertView .findViewById(R.id.CurrentfolderIdDone); lblFolderId.setText(dateFormat1.format(headerTitle.getTaskDate())); return convertView; } @Override public boolean hasStableIds() { return false; } @Override public boolean isChildSelectable(int groupPosition, int childPosition) { return true; } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
