Simple gauge view like speedmeter in android?

Question

I want to have a simple gauge view where i will define the start value and the end value and have a pointer to show given variable value.

Answer 1

I don't know whether the late answer is going to help or not. I also came to the same situation where i want to use a gauge to visualize data, since gauge is not given as widget in android, as a enthusiast i went for libraries like above which can be found through various links in the Internet, although it was quite helpful(thanks to the wonderful authors of it..) i find myself difficult to visualize the during certain situations, so another solution what i have done is for my app is i integreated the JavaScript gauges into my android application. You can do that by the following steps

1. Create an asset folder in our project-look this link and you will see how to create an asset folder if someone don't knows about it.
2. Next one is you have design an html page on how your page sholud look like, for eg- header,no.of guages etc... and place it in the folder asset.
3. There are many sites which provide the guages like This is one site or you can browse other sites and take whatever you feel cool...!! take it all including .js files and place it in the asset folder.
4. Android provides a class for handling webiview called "WebViewClient" you can browse more to know more about it in internet

5. This is sample code for viewing the webview content..

   web = (WebView) findViewById(R.id.webview01); progressBar = (ProgressBar) findViewById(R.id.progressBar1);

   web.setWebViewClient(new myWebClient());
   
     web.getSettings().setJavaScriptEnabled(true);
               web.post(new Runnable() {
                   @Override
                   public void run() {
                       web.loadUrl("file:///android_asset/fonts/guage.html");
                   }
               });
   

The above for loading the html & javscript.

 public class myWebClient extends WebViewClient
{
    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        // TODO Auto-generated method stub
        super.onPageStarted(view, url, favicon);
    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        // TODO Auto-generated method stub
        progressBar.setVisibility(View.VISIBLE);
        view.loadUrl(url);
        return true;

    }

    @Override
    public void onPageFinished(WebView view, String url) {
        // TODO Auto-generated method stub
        super.onPageFinished(view, url);

        progressBar.setVisibility(View.GONE);
    }
}

This the webview class
