        android:layout_height="match_parent" />

</RelativeLayout>

<强> WebViewActivity.java

package com.example.dhruv.demoapiaitutorial;

import android.app.ProgressDialog;

public class WebVIewActivity extends AppCompatActivity {

    private WebView mWebview;
    private ProgressDialog dialog; //creating object of progress dialog

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

        dialog = new ProgressDialog(this);
        dialog.setMessage("Please wait, your web is being open...");
        dialog.setCancelable(false);

        mWebview = (WebView) findViewById(R.id.webview);

        mWebview.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
                /*Showing progress dialog*/
                dialog.show();

            @Override

                /*You can also access url in this overridden method*/
                /*closing progress dialog*/
                dialog.dismiss();
            }
