Create 2 groups in android expandable listview
krish
Hi I have tried to develop expandable listview in android application.Now I have one doubts.How is creating 2 groups ion below my code for separate child details?
For Eg:
Group name: OrderInfo,CustomerInfo. Childname(OrderInfo):payment_method. Childname(CustomerInfo):name,email.
How to do this?Please help me.
this is my code:
SimpleExpandableListAdapter expListAdapter =
new SimpleExpandableListAdapter(
this,
createGroupList(), // Creating group List.
R.layout.group_row,
// Group item layout XML.
new String[] { "OrderInfo","CustomerInfo"}, // the key of group item.
new int[] { R.id.order,R.id.customer},
// ID of each group item.-Data under the key goes into this TextView.
createChildList(), // childData describes second-level entries.
R.layout.single_list_item,
new String[] {"KEY_ARTIST","KEY_DURATION","KEY_SUBTOTAL","KEY_DISCOUNT","KEY_COUPON","KEY_COST"},
new int[] { R.id.payment_label,R.id.total_label,R.id.discount_label,R.id.discount_label,R.id.coupon_label,R.id.cost_label}// Keys in childData maps to display.
);
setListAdapter( expListAdapter ); // setting the adapter in the list.
}catch(Exception e){
System.out.println("Errrr +++ " + e.getMessage());
}
}
/* Creating the Hashmap for the row */
@SuppressWarnings("unchecked")
private List createGroupList() {
ArrayList result = new ArrayList();
for( int i = 0 ; i < 1 ; ++i ) { // 15 groups........
HashMap m = new HashMap();
map.put( "CustomerInfo","CustomerInfo"); // the key and it's value.
m.put( "OrderInfo", OrderInfo);
result.add( m);
}
return (List)result;
}
/* creatin the HashMap for the children */
@SuppressWarnings("unchecked")
private List createChildList() {
ArrayList result = new ArrayList();
for( int i = 0 ; i < 1 ; ++i ) { // this -15 is the number of groups(Here it's fifteen)
/* each group need each HashMap-Here for each group we have 3 subgroups */
ArrayList secList = new ArrayList();
for( int n = 0 ; n < 1 ; n++ ) {
HashMap child = new HashMap();
Intent in = getIntent();
String payment_method = in.getStringExtra(KEY_ARTIST);
TextView lblPayment = (TextView) findViewById(R.id.payment_label);
/// lblPayment.setText(payment_method);
int payment;
payment=1;
String s= getIntent().getStringExtra("payment_method");
String s1= getIntent().getStringExtra("total");
String s2= getIntent().getStringExtra("subtotal");
String s3= getIntent().getStringExtra("discount");
String s4= getIntent().getStringExtra("coupon_discount");
String s5= getIntent().getStringExtra("shipping_cost");
child.put( "KEY_ARTIST", s);
child.put( "KEY_DURATION", s1);
child.put( "KEY_SUBTOTAL", s2);
child.put( "KEY_DISCOUNT", s3);
child.put( "KEY_COUPON", s4);
child.put( "KEY_COST", s5);
secList.add( child);
}
result.add( secList );
}
