I am new to android development and will greatly appreciate any help i can get.
I have a listview with icons and am having difficulty opening different activities from the items of the list.
the code is as follows:

Code (Text):

1.    
2.  package mCRM.android.hp;
3.  
4. import android.app.ListActivity;
5. import android.content.Context;
6. import android.content.Intent;
7. import android.os.Bundle;
8. import android.view.LayoutInflater;
9. import android.view.View;
10. import android.view.ViewGroup;
11. //import android.widget.AdapterView;
12. import android.widget.ArrayAdapter;
13. import android.widget.ImageView;
14. import android.widget.ListView;
15. import android.widget.TextView;
16. import android.widget.Toast;
17. public class first extends ListActivity {
18. public class MyCustomAdapter extends ArrayAdapter<String> {
19. public MyCustomAdapter(Context context, int textViewResourceId,
20. String[] objects) {
21. super(context, textViewResourceId, objects);
22. // TODO Auto-generated constructor stub
23. }
24. @Override
25. public View getView(int position, View convertView, ViewGroup parent) {
26. // TODO Auto-generated method stub
27. //return super.getView(position, convertView, parent);
28. LayoutInflater inflater=getLayoutInflater();
29. View first=inflater.inflate(R.layout.first, parent, false);
30. TextView TextView01=(TextView)first.findViewById(R.id.listView1);
31. TextView01.setText(DayOfWeek[position]);
32. TextView tv1 = (TextView)first.findViewById(R.id.listView1);
33. tv1.setText(choose[position]);
34. ImageView icon=(ImageView)first.findViewById(R.id.icon);
35.  
36. if (DayOfWeek[position]=="Opportunities"){
37. icon.setImageResource(R.drawable.opportunities);
38. }
39. else if(DayOfWeek[position]=="Accounts"){
40.  icon.setImageResource(R.drawable.accts);
41. }
42. else if(DayOfWeek[position]=="Contacts"){
43. icon.setImageResource(R.drawable.contacts);
44. }
45. else if(DayOfWeek[position]=="Analytics"){
46.  icon.setImageResource(R.drawable.analytics);
47. }
48. else{
49.  icon.setImageResource(R.drawable.bookmar);
50. }
51.  
52. return first;
53. }
54. }
55. String[] DayOfWeek = {"Opportunities", "Accounts", "Contacts",
56. "Analytics", "Bookmarks"}; // this is the array for the icons of the list
57. String[] choose = {"opportunities", "accounts", "contacts",
58.   "analytics", "bookmarks"}; //this is the array for the the different activities.
59. /** Called when the activity is first created. */
60. @Override
61. public void onCreate(Bundle savedInstanceState) {
62.    super.onCreate(savedInstanceState);
63.    // setListAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,DayOfWeek));
64.    setListAdapter(new MyCustomAdapter (first.this, R.layout.first, DayOfWeek));
65.  
66. }
67. @Override
68. protected void onListItemClick(ListView lv, View view, int position, long id) {
69. // TODO Auto-generated method stub
70.  
71.  //ArrayAdapter = (MyCustomAdapter)
72. super.onListItemClick(lv, view, position, id);
73.  //setContentView(R.layout.main);
74. //String selection = lv.getItemAtPosition(position).toString();
75. String openClass = choose[position];
76.  
77. try{
78.  Class selected = Class.forName("mCRM.android.hp."+ openClass);
79.  Intent selectedIntent = new Intent(this,selected);
80.  startActivity(selectedIntent);
81. }
82. catch(ClassNotFoundException e){
83.  e.printStackTrace();
84. }
85. Toast.makeText(this, openClass, Toast.LENGTH_LONG).show();
86. }
87.  
88. }
89.  

Thanks in advance

 

Thanks,

I got it solved by declaring another array that contains the different activities and concatenating it in an If-else statement. now i am having problem populating an expandable listview with data from a listview which is called dynamically from an external xml file. the complete code is on the following link http://androidforums.com/developer-101/417228-populating-expandablelistview-data-listview.html
