androidswiperefresh

This application is a example of android swipe refresh with simple code.
To add Swipe Refresh we need to add android SwipeRefreshLayout widget under activity_main.xml file

<!--refresh layout-->
    <android.support.v4.widget.SwipeRefreshLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/swiperefresh"
        android:layout_width="368dp"
        android:layout_height="495dp"
        tools:layout_editor_absoluteY="8dp"
        tools:layout_editor_absoluteX="8dp">       
</android.support.v4.widget.SwipeRefreshLayout>

Inside SwipeRefreshLayout we need to put our refresh widget such as ListView,TextView

Then we need to add menu

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/menu_refresh"
        android:title="@string/menu_refresh"
        app:showAsAction="never"
        />
</menu>

Now we need to add some code to our MainActivity.java class
First refer our SwipeRefreshLayout SwipeRefreshLayout SRL; inside onCreate() Method we need to add this simple code to hadle swiperefresh onClick listener

 SRL = (SwipeRefreshLayout) findViewById(R.id.swiperefresh);
        SRL.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener(){
            @Override
            public void onRefresh() {
                Log.i(TAG, "onRefresh called from SwipeRefreshLayout");

                // This method performs the actual data-refresh operation.
                // The method calls setRefreshing(false) when it's finished.
                myUpdateOperation();
            }
        });

Here myUpdateOperation() is a method to handle our refresh thing and calls setRefreshing(false) when it's finished We need to add same code under OnOptionsItemSelected method

case R.id.menu_refresh:
                Log.i(TAG, "Refresh menu item selected");

                // Signal SwipeRefreshLayout to start the progress indicator
                SRL.setRefreshing(true);

                // Start the refresh background task.
                // This method calls setRefreshing(false) when it's finished.
                myUpdateOperation();

                return true;
