ExpandableListView的扩展
public class ExpandableExample extends ExpandableListActivity {?
? ? @Override?
? ? public void onCreate() {?
? ? ? ? super.onCreate(savedInstanceState);?
? ? ? ? setListAdapter(new BaseExpandableListAdapterExample());?
? ? }?
}?
protected class BaseExpandableListAdapterExample extends BaseExpandableListAdapter {?
}?
然后继承后面两个
public View getGroupView(int groupPosition, boolean isExpanded,?
? ? ? ? ? ? ? ? ? ? ? ? ?View convertView, ViewGroup parent) {?
? ? View groupRow = getLayoutInflater().inflate(R.layout.group_row, null);?
? ? TextView textView = (TextView) groupRow.findViewById(R.id.text_group);?
? ? textView.setText(getGroup(groupPosition).toString());?
? ? return groupRow;?
}?
?
public View getChildView(int groupPosition, int childPosition,?
? ? ? ? ? ? ? ? ? ? ? ? ?boolean isLastChild, View convertView, ViewGroup parent) {?
? ? View childRow = getLayoutInflater().inflate(R.layout.child_row, null);?
? ? TextView textView = (TextView) childRow.findViewById(R.id.text_child);?
? ? textView.setText(getChild(groupPosition, childPosition).toString());?
? ? return childRow;?
}?
group_row.xml
<?xml version="1.0" encoding="utf-8"?>?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"?
? ? android:layout_width="fill_parent"?
? ? android:layout_height="fill_parent" >?
? ? <TextView?
? ? ? ? android:id="@+id/text_element"?
? ? ? ? android:layout_width="fill_parent"?
? ? ? ? android:layout_height="48dip"?
? ? ? ? android:textSize="20sp"?
? ? ? ? android:textColor="#fff"?
? ? ? ? android:layout_marginLeft="48dip"?
? ? ? ? android:gravity="center_vertical" />?
</RelativeLayout>?
