Android - Add progress bar WebView

Question

I am creating a simple app Android webview, but also following the guides, I can not implement a progress bar to my code. how can I implement a loading bar that will disappear after the page loads?

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        WebView view = (WebView) this.findViewById(R.id.webView);
        view.getSettings().setJavaScriptEnabled(true);
        view.setWebViewClient(new MyBrowser());
        view.loadUrl("http://www.abcdefcsadfg.org");
    }

    private class MyBrowser extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }
}

Answer 1

You can initialize a Progressbar in onCreate, like below and set its initial visibility to View.GONE.

progress = (ProgressBar) findViewById(R.id.progressBar);
progress.setVisibility(View.GONE);

And your MyBrowser should look like this

private class MyBrowser extends WebViewClient { 
     @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }

     @Override
    public void onPageFinished(WebView view, String url) {
         progress.setVisibility(View.GONE); 
         super.onPageFinished(view, url);
    }

     @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
         progress.setVisibility(View.VISIBLE);
         super.onPageStarted(view, url, favicon);
    }
}

You should declare progress bar in xml file and refer to it in the main activity so that it appears in your application. Set its progress in MyBrowser.
