Steps to Create WebView in Android

1. So, Now open Android Studio and Create a new Project for WebView In Android.

2. Then select Activity of an Android Application. Generally, people choose Empty Activity.

3. So, Give the Name to the application and set the minimum version of SDK to run Android Application.

4. Then Open the activity_main.xml file (app>res>layout>activity_main.xml) and change parent Layout ConstrainLayout to RelativeLayout.

5. So, Delete the default TextView code and add WebView code and set height and width as match parent cause we want to display this WebView to cover the entire screen. Then set id as well.

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

6. Open MainActivity.java file(app>java>com.example.WebView>MainActivity.java) and create Webview variable. before the onCreate() method.

WebView webView;

7. Then initialize webView with activity_main.xml WebView.

webView = findViewById(R.id.webview);

8. So, now we have to load the URL by the method provided by WebView classes.

webView.loadURL("https://www.codeseasy.com");

9. Every time when we use WebView in the Android application it will load the URL on the external browser, but if we want to load the URL inside our Android Application. We can add the below code to do that.

webView.setWebViewClient(new WebViewClient());

10. Then now open the AndroidMenifest.xml file (app>manifest>AndroidMenifest.xml) and write code for user permission for INTERNET.

<uses-permission android:name="android.permission.INTERNET"/>

So, Now if we press the back button after loading the URL it would close the application. We need to override this using onBackPressed() method.

11. Then press ctrl+O and search the onBackPressed() method. This method will be written outside the onCreate() method.

12. We have to check if going back is possible or not. Then to get users back to the previous page we have the method goBack() in WebView that is used to get users back to the previous page.

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