Android Implementing Designs for Android Customizing a ListView for the Inbox Adding a Swipe-to-Refresh Gesture

adding swipes

Let's add a SwipeRefreshLayout to the activity below. Start by declaring a public member variable named mRefreshLayout.

import android.os.Bundle;
import android.support.v4.widget.SwipeRefreshLayout;
import android.support.v4.widget.SwipeRefreshLayout.OnRefreshListener;

public class MainActivity extends ListActivity {

     * Some code has been omitted for brevity

    public void onCreate(Bundle savedInstanceState) {

    public OnRefreshListener mOnRefreshListener = new OnRefreshListener() {
        public void onRefresh() {
            // Code that refreshes the content in the layout...
     public mRefreshLayout;

Hi there,

When you declare a variable you need to tell the compiler what type of veriable it is - that way, the compiler knows how much memory to allocate to it. You also need to declare the variable outside of the scope of the onRefreshListener so you have it in the wrong place.

Start above onCreate so the variable is only inside the class. Then declare it like:

public SwipeRefreshLayout mRefreshLayout;

That should get you through the first bit.

Sounds like you've got your code in the wrong place - can you post all the code, please?

I've answered in there - as I thought, your code wasn't quite in the right place.
