How To Put A Progress Bar In An Application Using Tabs

I have a main java file that sets up a series of tabs where each one calls a seperate activity in this case each activity is linked to a webpage. I am trying to implemente a progre

Solution 1:

Hey this is exactly what I do in my webviews

In the onCreate method of the webview[in your case it may be your tabActivity] do this

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
    setContentView(R.layout.webview_simple);
}

then in the webview client do this

privateclassMyWebViewClientextendsWebViewClient {

public synchronized booleanshouldOverrideUrlLoading(WebView view, String url){
}// and all ur implementationpublicvoidonPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        setProgressBarIndeterminateVisibility(false);
    }

    publicvoidonPageStarted(WebView view, String url, Bitmap favicon) {
        setProgressBarIndeterminateVisibility(true);
        super.onPageStarted(view, url, favicon);            
    }

}

Hope it helps. I am overriding the onPageFinished and onPageStarted in the webview client. Its difficult to do it from onProgressChanged. I tried it but I found this to be simple.
