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;
