Question

I have this code and i would like to use asyncTask manager with this to let the user know something is happening. How would i allow this to happen with this snippet of code. i cant seem to figure it out. I know the asyncTask will be better than using a Hanlder. Or would it?
But anyway here is an example. if anyone can help out. Please do. Thanks.

     enter.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
             item = book.getText().toString();
             searchForItem();


        }
    });

i would like to run this method with a progress dialog spinner letting the user know something is happening. How do i do this, and stop the spinner when the web page is loaded?

Here is my SearchForItem().

    public void searchForBook(){

    String url = "www.example.com";
    browser = (WebView)findViewById(R.id.shopView);
    browser.setWebViewClient(new BookLookupbrowser());
    browser.getSettings().setJavaScriptEnabled(true);
    browser.loadUrl(url);

Answer 1

1. Create a child class of AsyncTask. Override the three main methods, onPreExecute, onPostExecute, doInBackground.
2. In onPreExecute, start your ProgessDialog.
3. In doInBackground, run your searchForBook() method.
4. In onPostExecute, dismiss your ProgressDialog.
5. If you need functionality for cancelling your AsyncTask, more methods exist and are well documented in the documentation.
6. With your new AsyncTask subclass, start it in the onClick method from your first snippet.
7. If any of this doesn’t make sense, refer to Painless Threading in the Android Documentation, as it is extremely helpful.

Good Luck!
