我正在使用ExpandableListView來創建帶有子項目的自定義列表。我的第一個列表已成功創建，但不可點擊，因此無法展開。ExpandableListView在點擊時不會展開
這裏是我的代碼...
private ExpandableListView listview;
private TheaterListAdapter adapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.theater_list);
this.m_movieList = "A list of Movie (Custom Object)"
listview = (ExpandableListView) findViewById(R.id.theater_listview);
adapter = new TheaterListAdapter(getApplicationContext());
listview.setAdapter(adapter);
private class TheaterListAdapter extends BaseExpandableListAdapter {
public TheaterListAdapter(Context c) {
mContext = c;
}
@Override
public Object getChild(int groupPosition, int childPosition) {
String MovieId = m_movieList.getMovies().get(groupPosition)
.getShowTimes().get(childPosition).getMovieId();
for (MovieInfo movie : m_movieList.getMovies()) {
if (MovieId.equalsIgnoreCase(movie.getId())) {
return movie;
}
}
return null;
}
@Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
@Override
public View getChildView(int groupPosition, int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
ExpandedHolder holder;
View rowView = convertView;
if (rowView == null) {
holder = new ExpandedHolder();
LayoutInflater li = getLayoutInflater();
rowView = li.inflate(R.layout.theater_expanded_view, null);
holder.img_movie_poster = (ImageView) rowView
.findViewById(R.id.imgMoviePoster);

.findViewById(R.id.imgRatingStar);

.findViewById(R.id.txtMovieName);

.findViewById(R.id.txtPgDuration);

.findViewById(R.id.txtShowTimes);
rowView.setTag(holder);
} else {

}
holder.txt_movie_name.setText("Twilight");
holder.txt_pg_duration.setText("PG 90 min");
