Hi I have one activity which invoked another activity
roomIntent.putExtra("roomName",roomNM );
roomIntent.setClass(AddScheduler.this,RoomList.class);
startActivityForResult(roomIntent,Room_SELECT);
protected void start(Intent intent)
{
this.startActivityForResult(intent,Room_SELECT);
}
protected void onActivityResult(int requestCode, int resultCode,
Intent data)
{
System.out.println (requestCode);
switch(requestCode)
{
case Room_SELECT:
System.out.println (resultCode); //here it
returns 0
if (resultCode == RESULT_OK)
{
...........
//Because result code returns 0 therefore this if conditio does not
execute.
}
}
}
And here is my other activity which returns result.
public class RoomList extends ListActivity
{
super.onCreate(savedInstanceState);
Bundle extras = getIntent().getExtras();
if(extras !=null)
{
value = extras.getString("roomName");
sw = getSwitchNameArray(value);
}
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_multiple_choice,
sw));
final ListView listView = getListView();
listView.setItemsCanFocus(true);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setOnItemClickListener(new ListView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2,
long arg3)
{
// TODO Auto-generated method stub
System.out.println ("User checked boxes");
if (listView.isItemChecked(arg2))
{
System.out.println
("###"+listView.getItemAtPosition(arg2));
room = (String)
listView.getItemAtPosition(arg2);
selectedRooms.add(room);
System.out.println ("Size
is"+selectedRooms.size());
}
else
{
String str = (String)
listView.getItemAtPosition(arg2);
selectedRooms.remove(str);
System.out.println ("Size
is"+selectedRooms.size());
}
}
});
@Override
protected void onPause()
{
super.onPause();
System.out.println ("User click on back button");
mySwitches = new String[selectedRooms.size()];
selectedRooms.toArray(mySwitches);
int str = mySwitches.length;
System.out.println ("!...@#!@#...@#"+str);
Intent returnIntent = new Intent();
//returnIntent.putExtra("SelectedSwitches",selectedRooms);
returnIntent.putExtra("SelectedSwitches", str);
setResult(RESULT_OK,returnIntent);
System.out.println ("Before calling finish");
finish();
System.out.println ("After calling finish");
}
public String[] getSwitchNameArray(String rn)
{
......returns string array
}
I think in resultCode I get 0 because I write
setResult(RESULT_OK,returnIntent); inside onPause () method. Or there
is another problem? I had write that inside onPause bacause in this
activity I am calculating name of selected items. And I never knows
when user had finished selecting items. After writing code inside
onPause I know what item user had selected from list and I can pass
them to the calling activity.
I think better approach is to add one button means suppose user click
on save button then selected item will be sent to the calling
activity. Want your opinion? where should write code. If it doesn't
affect write inside onPause() then why I got 0 from resultCode.
