Here is the my subclass of Application
public class MyApp extends Application {
private HashMap<String, Boolean> selectedContacts = null;
public HashMap<String, Boolean> getSelectedContacts() {
return this.selectedContacts;
}
public void setSelectedContacts(HashMap<String, Boolean> sc) {
this.selectedContacts = sc;
}
}
Below are the methods onActivityResult() and onClick() in my Messenger
Activity. In onActivityResult(), I set the private member variable of the
MyApp Class. In the onClick() method, I call the accesseror method.
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
switch (reqCode) {
case R.integer.contact_manager:
if (resultCode == RESULT_CANCELED)
Log.d(getString(R.string.debug_tag), "FAILURE");
if (resultCode == RESULT_OK) {
Log.d(getString(R.string.debug_tag), "SUCCESS");
MyApp appState = ((MyApp)getApplication());
appState.setSelectedContacts((HashMap<String, Boolean>) data
.getSerializableExtra("selectedContacts"));
}
break;
}
}
add_contact_button.setOnClickListener(new OnClickListener() {
>
> public void onClick(View v) {
>
>
>> Intent i = new Intent(Messenger.this, ContactManager.class);
>
> MyApp appState = ((MyApp)getApplication());
>
> HashMap<String, Boolean> sc = appState.getSelectedContacts();
>
>
>
> if (sc != null) {
>
> int totalContacts = sc.size();
>
> if (totalContacts > 0) {
>
> Bundle bundle = new Bundle();
>
> bundle.putSerializable("selectedContacts",
>
> sc);
>
> i.putExtras(bundle);
>
> }
>
> }
>
> startActivityForResult(i, R.integer.contact_manager);
>
>
>> }
>
> });
