I'm creating expandable list view in Android. I have add three textview in relative layout and two buttons in horizontal linear layout means this two buttons are added in one row, so how can I fire click event on those two buttons?
And I want to call another activity on button click in expandable list view. But I did not find any idea how to click on child in ExpandableListView
.
Here is my XML file.

here is my ExpandableListAdapter
class -
public class ExpandableListAdapter 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;
Context context;
public ExpandableListAdapter(Context context, List<String> listDataHeader,
HashMap<String, List<String>> listChildData) {
this._context = context;
this._listDataHeader = listDataHeader;
this._listDataChild = listChildData;
}
public ExpandableListAdapter
(My_Project my_Project, List createGroupList,
int listGroup, String[] strings, int[] is, List createChildList,
int childItem, String[] strings2, int[] is2)
{
// TODO Auto-generated constructor stub
}
@Override
public Object getChild(int groupPosition, int childPosition)
{
//this.get(groupPosition).getChildren().get(childPosition);
String strchildPosition = this._listDataChild.get(this._listDataHeader.get(groupPosition)).get(childPosition);
System.out.println("Child Position =" + strchildPosition);
return this._listDataChild.get(this._listDataHeader.get(groupPosition))
.get(childPosition);
}
@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.child_item, null);
}
TextView txtListChild = (TextView) convertView.findViewById(R.id.TextView_Projectdetails);
TextView txtOneListChild = (TextView)convertView.findViewById(R.id.textOne);
TextView txtTwoListChild = (TextView)convertView.findViewById(R.id.textTwo);
txtListChild.setText(childText);
txtOneListChild.setText(childText);
txtTwoListChild.setText(childText);
Button btnAssgnTask = (Button)convertView.findViewById(R.id.button_EditedTask);
btnAssgnTask.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//Intent i=new Intent(context,Assign_Task.class);
//StartElementListener()
}
});
Button btnViewTask = (Button)convertView.findViewById(R.id.buttonViewTask);
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) {
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 false;
}
@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
}
Here is my Activity code -
public class My_Project extends ExpandableListActivity
{
expListView = (ExpandableListView) findViewById(android.R.id.list);
expListView.setOnGroupClickListener(new OnGroupClickListener()
{
@Override
public boolean onGroupClick(ExpandableListView parent, View v,
int groupPosition, long id)
{
return false;
}
});
expListView.setOnGroupExpandListener(new OnGroupExpandListener() {
@Override
public void onGroupExpand(int groupPosition) {
Toast.makeText(getApplicationContext(),
dtrProjectNAmeSize.length + " Expanded",
Toast.LENGTH_SHORT).show();
}
});
expListView.setOnGroupCollapseListener(new OnGroupCollapseListener() {
@Override
public void onGroupCollapse(int groupPosition) {
Toast.makeText(getApplicationContext(),
dtrProjectNAmeSize.length + " Collapsed",
Toast.LENGTH_SHORT).show();
}
});
expListView.setOnChildClickListener(new OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
// TODO Auto-generated method stub
int cp = (int) mAdapter.getChildId(groupPosition, childPosition);
if(cp == 3)
{
switch (cp)
{
case 3:
break;
}
}
return false;
}
});
mAdapter = new SimpleExpandableListAdapter(
this,
groupData,
R.layout.list_group,
new String[] { Project_Name },
new int[] {R.id.lblListHeader },
childData,
R.layout.child_item,
new String[] { Project_Date_Created , Project_End_Date , Project_Is_Active},
new int[] { R.id.TextView_Projectdetails , R.id.textOne , R.id.textTwo }
);
expListView.setAdapter(mAdapter);
}
}
You can set setOnChildClickListener of chid of the expandable listview then can you go to the other activity according to the value of the array list that are use for create expandable listview.
menuExpandableListView
.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
@Override
public boolean onChildClick(
ExpandableListView parent, View v,
int groupPosition, int childPosition,
long id) {
GoCategory(mainMenusList.get(groupPosition)
.getPagesList().get(childPosition));
return false;
}
});
Or you can do this
@Override
public View getChildView(final int groupPosition, final int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
Page page =(Page) getChild(groupPosition, childPosition);
convertView = inflater.inflate(R.layout.child_list_layout, null);
Button button1=(Button)convertView.findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Your code here....
}
});
return convertView;
}
