Swipe to refresh Android Activity (SwipeRefreshLayout)

In this tutorial, we will create swipe-to-refresh functionality in the Android. For this purpose, SwipeRefreshLayout widget should be used.

The instance of SwipeRefreshLayout adds an OnRefreshListener method and implements the code logic that will load on refresh. The vertical swipe displays a distinctive progress bar when the user swipes. The progress bar call setRefreshing(true) when it shows the progress animation or calls setRefreshing(false) to cancel.

Swipe to refresh Android Activity Example

In the activity_main.xml file, implement SwipeRefreshLayout widget.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout 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:id="@+id/refreshLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="example.javatpoint.com.swiperefreshlayout.MainActivity">

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <TextView
            android:id="@+id/textView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="229dp"
            android:text="Hello World!"
            android:textSize="18dp"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toTopOf="parent" />
    </RelativeLayout>
</android.support.v4.widget.SwipeRefreshLayout>

Create an activity MainActivity.java and add the following code. In this class, we are checking the network connectivity onRefresh() the swipe.

MainActivity.java

package example.javatpoint.com.swiperefreshlayout;

import android.content.Context;
import android.graphics.Color;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.support.v4.widget.SwipeRefreshLayout;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {
    SwipeRefreshLayout swipeRefreshLayout;
    TextView textView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        swipeRefreshLayout = findViewById(R.id.refreshLayout);
        textView = findViewById(R.id.textView);
        swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                       swipeRefreshLayout.setRefreshing(false);
                       //your code on swipe refresh
                       //we are checking networking connectivity
                        boolean connection=isNetworkAvailable();
                        if(connection){
                            textView.setText("internet connect");
                            textView.setTextColor(Color.GREEN);
                        }
                        else{
                            textView.setText("not connected");
                            textView.setTextColor(Color.RED);
                        }

            }
        });
        swipeRefreshLayout.setColorSchemeColors(Color.YELLOW);
    }
    public boolean isNetworkAvailable(){

        ConnectivityManager connectivityManager=(ConnectivityManager) this.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo=connectivityManager.getActiveNetworkInfo();
        return networkInfo !=null;
    }
}
