Android Swipe Refresh

This article is about android swipe refresh with simple code.
To add Swipe Refresh we need to add android SwipeRefreshLayout widget under activity_main.xml file

	<?xml version="1.0" encoding="utf-8"?>
	<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	xmlns:app="http://schemas.android.com/apk/res-auto"
	xmlns:tools="http://schemas.android.com/tools"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	tools:context="com.example.sagorsarker.addingswiprefresh.MainActivity">
	<!--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">
	<!-- <ListView
	android:id="@android:id/list"
	android:layout_width="match_parent"
	android:layout_height="match_parent" />-->
	<TextView
	android:id="@+id/text_edit"
	android:layout_width="wrap_content"
	android:layout_height="wrap_content"
	android:layout_weight="1"
	android:text="My Text" />
	</android.support.v4.widget.SwipeRefreshLayout>
	</LinearLayout>

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;
