Question

I have this code for managing some countrys on my database;

class checkCountryAsync extends AsyncTask<String, String, String> {

    @Override
    protected void onPreExecute() {
       super.onPreExecute();
       setContentView(R.layout.main);

    }
    @Override
    protected String doInBackground(String... aurl) {
        MDPIActivity.this.runOnUiThread(new Runnable() {

            public void run() {
                  CountryTable country = new CountryTable() ;
                  country.EnterCountry();
            }
        });
        return null;
    }
}

With this, I would like to set the content View and then in background, that the method onBackground works, but I have still to wait for the content view until the onBackground method is not finished.

Thank you.

i don’t see any reason for putting the setContentView() in the onPreExecute method, it should be in the onCreate method to avoid any kind of NullPointerException when you will try to find your views, and for your AsyncTask , you should just use the onPostExecute() which is executed after the method doInBackground()
