有一个很好的解释，这可能对任何试图做同样的人有用！！！
public class ExpList extends ExpandableListActivity
{
String gametype;
// strings for group elements
static final String arrGroupelements[] =
{
"POKER TOURNAMENTS",
"SLOTS TOURNAMENTS",
"ROULLETTE/CRAPS TOURNAMENTS",
"BLACKJACK TOURNAMENTS",
"BINGO/CHARITY BINGO"
};
// strings for child elements
static final String arrChildelements[][] =
{
{
"TEXAS HOLD'EM",
"OMAHA HIGH-LOW",
"SEVEN CARD STUD",
"THREE CARD POKER",
"OTHER POKER VARIANTS",
"ONLINE/SATTELITE TOURNAMENTS"
},
{
"SLOTS"
},
{
"ROULLETTE",
"CRAPS"
},
{
"BLACKJACK"
},
{
"BINGO"
}
};
并按以下方式处理 onChildClick 函数，以在下面单击该子项时将字符串的值设置为“TEXAS HOLD 'EM”
@Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
//ExpandableListAdapter adapter = getExpandableListAdapter();
gametype = ExpList.arrChildelements[groupPosition][childPosition];
//---------------------
Intent pullt = new Intent(ExpList.this,
SearchActivity.class);
Bundle bundle = new Bundle();
bundle.putString("gametype", gametype);
pullt.putExtras(bundle);
pullt.putExtra("gametype", gametype);
startActivity(pullt);
//---------------------
return false;
}
