Hi All,
Using the ExpandableListActivity, I am not sure how to get the item
clicked and then forward it to another activity based on the selected
item.
Attached is the below code.
=======================================================================================
import android.app.ExpandableListActivity;
import android.database.DataSetObserver;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.Gravity;
import android.view.MenuItem;

import android.view.ViewGroup;
import android.view.ContextMenu.ContextMenuInfo;
import android.widget.AbsListView;
import android.widget.BaseExpandableListAdapter;
import android.widget.CursorAdapter;
import android.widget.ExpandableListAdapter;
import android.widget.ExpandableListView;
import android.widget.TextView;
import android.widget.Toast;
import
android.widget.ExpandableListView.ExpandableListContextMenuInfo;
public class Hookup extends ExpandableListActivity {
ExpandableListAdapter mAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set up our adapter
mAdapter = new MyExpandableListAdapter();
setListAdapter(mAdapter);
registerForContextMenu(getExpandableListView());
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
menu.setHeaderTitle("Hookup Menu");
menu.add(0, 0, 0, R.string.hello);
}
@Override
public boolean onContextItemSelected(MenuItem item) {
System.out.println("Insidded onContextItemSelected");
// Intent intent = new Intent();
// intent.setClass(this, HookupMapView.class);
// startActivity(intent);
ExpandableListContextMenuInfo info =
(ExpandableListContextMenuInfo)
item
.getMenuInfo();
String title = ((TextView)
info.targetView).getText().toString();
int type = ExpandableListView
.getPackedPositionType(info.packedPosition);
if (type == ExpandableListView.PACKED_POSITION_TYPE_CHILD) {
int groupPos = ExpandableListView
.getPackedPositionGroup(info.packedPosition);
int childPos = ExpandableListView
.getPackedPositionChild(info.packedPosition);
Toast.makeText(
this,
title + ": Child " + childPos + "
clicked in group "
+ groupPos,
Toast.LENGTH_SHORT).show();
return true;
} else if (type ==
ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
int groupPos = ExpandableListView
.getPackedPositionGroup(info.packedPosition);
Toast.makeText(this, title + ": Group " + groupPos + "
clicked",
Toast.LENGTH_SHORT).show();
return true;
}
return false;
}
