java – WebView on Android, editing HTML

Question:

I am able to load the URL on my device using WebView , but the page that loads is not mobile-friendly. I would like to know if I can access the page, but eliminating some parts of the HTML. Code below:

MainActivity.java:

public class MainActivity extends ActionBarActivity {

Button btEntrar;

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

final WebView myWebView = (WebView) findViewById(R.id.webView1);

WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);

myWebView.setWebViewClient(new WebViewClient());

myWebView.loadUrl("SITE");

btEntrar = (Button) findViewById(R.id.btEntrar);
}


private class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
    if (Uri.parse(url).getHost().equals("SITE DESEJADO")) {
        // This is my web site, so do not override; let my WebView load the page
        return false;
    }
    // Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
    startActivity(intent);
    return true;
}
}

I want to leave only the login field, password and login button, and then pass it on normally.

Answer:

You can use the loadData method. To learn more about the loadData method and also about other methods that can be used in your case, consult the documentation .

Example of use:

webview.loadUrl("http://example.com/");

String example = "<html><body>My first body<b>LIKE</b> mee.</body></html>";
webview.loadData(example, "text/html", null);
  • Sample code available in documentation.
