How to create Swipe Refresh for a WebView Layout in Android Studio.

First, we have to implement the Swipe Refresh dependency in “build.gradle(Module :app) given below.

// Swipe Refresh Layout
    implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.2.0"

Now, we have to create a “SwipeRefreshLayout” in your layout.

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context=".MainActivity">

    <androidx.swiperefreshlayout.widget.SwipeRefreshLayout
        android:id="@+id/swipeContainer"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <androidx.core.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <WebView
                android:id="@+id/webView"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />

        </androidx.core.widget.NestedScrollView>

    </androidx.swiperefreshlayout.widget.SwipeRefreshLayout>


</androidx.constraintlayout.widget.ConstraintLayout>

Now, we have to implement the Java code in MainActivity are given below.

public class MainActivity extends AppCompatActivity {
    WebView webView;
    SwipeRefreshLayout swipeRefreshLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        swipeRefreshLayout = findViewById(R.id.swipeContainer);
        swipeRefreshLayout.setOnRefreshListener(this::loadWeb);

        loadWeb();
    }

    @SuppressLint("SetJavaScriptEnabled")
    public void loadWeb() {
        webView = findViewById(R.id.webView);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl("https://androidappmaterial.in/");
        swipeRefreshLayout.setRefreshing(true);
        webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view, String url) {
                swipeRefreshLayout.setRefreshing(false);
            }
        });
    }

    @Override
    public void onBackPressed() {
        super.onBackPressed();
        if (webView.canGoBack()) {
            webView.goBack();
        } else {
            finish();
        }
    }
}
