4,861 PointsI can't seem to make sense of this question, any help will be appreciated
I'm not sure what code will work as I've tried several...
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.view.ListView;
public class GameListActivity extends ListActivity {
public String[] mGames = {
"Age of Empires",
"Civilization",
"Minecraft",
"SimCity"
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game_list);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mGames);
setListAdapter(adapter);
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
game.writeString(mGames);
}
// This is a helper method to tally votes on a back-end system
public void sendVote(String game) {
VoteService.recordVote(game);
}
}

Treehouse TeacherHey Derrick! The 'game' variable doesn't exist inside onListItemClick. If you remove that line it should pass the first task.

"Now we can do something with the item that was tapped on. We have a helper method, "sendVote()", that will log the user's vote for their favorite game. Call it with the correct game from the list."

4,861 PointsThanks Ben, I did get past the first task, it's the second task I'm having trouble with.

Treehouse TeacherAfter the call to super, we're supposed to call 'sendVote' and pass in the game title of the list item we clicked. We can get the game title by using the mGames array and the position parameter.

Treehouse TeacherInstead of:
game.writeString(mGames);
we need to call sendVote:
sendVote(...)
and pass in the game title:
mGames[...]
of the list item we clicked:
mGames[position]
So:
sendVote(mGames[position]);
