@Override
//Keep webview in app when clicking links
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;

Back & Exit Feature:
MainActivity.java
//set back button functionality @Override public void onBackPressed() { //if user presses the back button do this if (webview.isFocused() && webview.canGoBack()) { //check if in webview and the user can go back webview.goBack(); //go back in webview } else { //do this if the webview cannot go back any further new AlertDialog.Builder(this) //alert the person knowing they are about to close .setTitle("EXIT") .setMessage("Are you sure. You want to close this app?") .setPositiveButton("Yes", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { finish(); } }) .setNegativeButton("No", null) .show(); } }4. Swipe Down to Refresh:
activity_main.xml
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout android:id="@+id/swipeContainer" android:layout_width="match_parent" android:layout_height="match_parent"> <WebView android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/webView" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:layout_alignParentEnd="true" tools:ignore="MissingConstraints" /> </androidx.swiperefreshlayout.widget.SwipeRefreshLayout>MainActivity.java
SwipeRefreshLayout mySwipeRefreshLayout;//Swipe to refresh functionality mySwipeRefreshLayout = (SwipeRefreshLayout)this.findViewById(R.id.swipeContainer); mySwipeRefreshLayout.setOnRefreshListener( new SwipeRefreshLayout.OnRefreshListener() { @Override public void onRefresh() { webview.reload(); } } );private class WebViewClientDemo extends WebViewClient { @Override //Keep webview in app when clicking links public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } @Override public void onPageFinished(WebView view, String url) { super.onPageFinished(view, url); mySwipeRefreshLayout.setRefreshing(false); } }import android.app.AlertDialog; import android.content.Context; import android.content.DialogInterface; import android.net.ConnectivityManager; import android.net.NetworkInfo; import android.os.Bundle; import android.util.Log; import android.webkit.WebView; import android.webkit.WebViewClient; import androidx.appcompat.app.AppCompatActivity; import androidx.swiperefreshlayout.widget.SwipeRefreshLayout; public class MainActivity extends AppCompatActivity { String websiteURL = "https://youtube.com/technicalsangrah"; // sets web url private WebView webview; SwipeRefreshLayout mySwipeRefreshLayout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); if( !
