私が見つけたいくつかのコードを適応させることによって、 expandableListView をカスタマイズしようとしています。これにより、カスタム アダプターが呼び出され、リスト ビューに必要な行が拡張されます。
私の問題:他のレイアウトコンポーネントでそれを使用する必要があるため、 setContentView を呼び出して必要な場所で listView を膨らませる必要があります。私の試みはすべてアプリのクラッシュで終わります。レイアウト内で動作するように以下のコードを適応させる方法を教えてください..?
主な活動:
public class MainActivity extends ExpandableListActivity implements
OnChildClickListener {
private static final String[] Groups = { "G1", "G2",
"G3", "G4" };
private static final String[] Services = { "Service1",
"Service2", "Service3", "Service4", "Service5",
"Service6" };
private static final String[] Test = { "Test1", "Test2",
"Test3", "Test4" };
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ExpandableListView expandbleLis = getExpandableListView();
expandbleLis.setDividerHeight(2);
expandbleLis.setGroupIndicator(null);
expandbleLis.setClickable(true);
setGroupData();
setChildGroupData();
NewAdapter mNewAdapter = new NewAdapter(groupItem, childItem);
mNewAdapter
.setInflater(
(LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE),
this);
expandbleLis.setAdapter(mNewAdapter);
expandbleLis.setOnChildClickListener(this);
}
public void setGroupData() {
for (int i = 0; i < 4; i++) {
groupItem.add(Groups[i]);
}
}
ArrayList<String> groupItem = new ArrayList<String>();
ArrayList<Object> childItem = new ArrayList<Object>();
public void setChildGroupData() {
/**
* Add Data For Services
*/
ArrayList<String> child = new ArrayList<String>();
for (int i = 0; i < 6; i++) {
child.add(Services[i]);
}
childItem.add(child);
/**
* Add Data For Test
*/
child = new ArrayList<String>();
for (int i = 0; i < 4; i++) {
child.add(Test[i]);
}
childItem.add(child);
/**

*/
child = new ArrayList<String>();
child.add("Dummy Text");
child.add("Dummy Text");
child.add("Dummy Text");
child.add("Dummy Text");
childItem.add(child);
/**

*/
child = new ArrayList<String>();
child.add("Dummy Text");
child.add("Dummy Text");
child.add("Dummy Text");
child.add("Dummy Text");
childItem.add(child);
}
@Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
Toast.makeText(MainActivity.this, "Clicked On Child",
Toast.LENGTH_SHORT).show();
return true;
