SwipeRefreshLayout error - android-activity

Question

I am trying to implement swiperefreshlayout and I am getting error at "this"
public class viewBets_activity extends ActionBarActivity {
SwipeRefreshLayout swipeLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.viewbets);
swipeLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_container);
swipeLayout.setOnRefreshListener(this);
swipeLayout.setColorScheme(android.R.color.holo_blue_bright,
android.R.color.holo_green_light,
android.R.color.holo_orange_light,
android.R.color.holo_red_light);
}
public void onRefresh() {
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
swipeLayout.setRefreshing(false);
}
}, 5000);
}
}
I am getting error at swipeLayout.setOnRefreshListener(this); screenshot below

Answer 1

Well, now that you added the screenshot, the error is clear.
You're passing the wrong argument into setOnRefreshListener()! And of course, this makes sense, if you think about it. Your class is a ActionBarActivity. You're trying to set the OnRefreshListener as an ActionBarActivity...doesn't make any sense! You need to change your code to this:
swipeLayout.setOnRefreshListener(new OnRefreshListener()
{
#Override
public void onRefresh()
{
// what you want to happen onRefresh goes here
}
});
Here, you're creating a new OnRefreshListener object which you're adding as the listener.
For the future, in general, any time you have a setOn______Listener() method, the argument you'll be passing will be a On_____Listener object that you've customized. You can either created separately, or create it right in the set method the way I did in my answer.

Answer 2

Your class is missing
implement SwipeRefreshLayout.OnRefreshListener
This allows the listener to refer to the overridden method onRefresh when passing through this as the argument for setOnRefreshListener
