The example in this article describes how Android implementations add multiple ListView to an activity. Share to everyone for your reference, specific as follows:

ListView's ID is generally like this android:id= "@id/android:list". Note that the activity at this time is listactivity, and so far I have found no way to add more than one activity. To add multiple listview, the activity used if the general Activity,listview ID also to define themselves, to Android:id= "@+id/mylist." And then, like using a generic control, initialization is OK. As for adapter I inherited the Baseadapter, define a adapter for each ListView, and then the corresponding settings adapter on it.

Reference code:

public class MyActivity extends activity implements Onclicklistener {private listviewlistview_psychologicalstate,
Listview_weatherstate;
Private ListAdapter listadapter_psychologicalstate,listadapter_weatherstate; Private arraylist<string> Psychologicalstatearray = new arraylist<string> (), Weatherstatearray = new
Arraylist<string> ();
Private String [] strpsychologicalstate = new string[]{"Depressed", "hyper", "pressure", "insomnia", "drowsiness", "easy to Panic"};
Private String [] strweatherstate = new string[]{"Hot and humid", "hot", "cold"}; @Override public void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (
R.layout.personalizedorderview);
Findview ();
public void Findview () {listview_psychologicalstate = (ListView) Findviewbyid (R.id.psychologicalstatelistid);
Listview_weatherstate = (ListView) Findviewbyid (R.id.weatherstatelistid);
for (int i = 0;i<strpsychologicalstate.length;i++) Psychologicalstatearray.add (Strpsychologicalstate[i]); for (int i = 0;i<strweatherstate.length; i++) Weatherstatearray.add (Strweatherstate[i]);
Listadapter_psychologicalstate = new Getinflamedadapter (This,psychologicalstatearray);
Listview_psychologicalstate.setadapter (listadapter_psychologicalstate);
Listadapter_weatherstate = new Getinflamedadapter (This,weatherstatearray);
Listview_weatherstate.setadapter (listadapter_weatherstate);  public class Getinflamedadapter extends Baseadapter {private context; private layoutinflater minflater; private
Arraylist<string> ArrayList; Public Getinflamedadapter (Context context,arraylist<string> ArrayList) {this.context=context; this.arraylist =
ArrayList
Minflater = (layoutinflater) this.context.getSystemService (Context.layout_inflater_service); @Override public int GetCount () {//TODO auto-generated a stub return Arraylist.size ();} @Override the public Object GetItem (int position) {//TODO auto-generated Method stub return Arraylist.get (position);} @Override public Long GetItem Id (int position) {//TODO auto-Generated method stub return position; @Override public View getview (int position, View Convertview, ViewGroup parent) {//TODO auto-generated method stub con
Vertview = minflater.inflate (r.layout.inflamedchild, NULL);
Viewholder viewholder = null;
  Viewholder = new Viewholder ();
  Viewholder.label = (TextView) Convertview.findviewbyid (R.ID.BODYSTATEID1);
ViewHolder.label.setText (Arraylist.get (position). ToString ());
ViewHolder.label.setTextColor (Color.green);
ViewHolder.label.setTextSize (22);
Convertview.settag (Viewholder);
return convertview;

 Private class Viewholder {TextView label;}}
