How do I show and then remove an android progress dialog

android, progressdialog

Solution

here is the code that I got to work

private class UpdateFeedTask extends AsyncTask<MyActivity, Void, Void> {

    private ProgressDialog mDialog;

    protected void onPreExecute() {
        Log.d(TAG, " pre execute async");
        mDialog = ProgressDialog.show(MyActivity.this,"Please wait...", "Retrieving data ...", true);

    }

    protected void onProgressUpdate(Void... progress) {
        Log.d(TAG, " progress async");     
    }

    @Override
    protected Void doInBackground(MyActivity... params) {
        // TODO Auto-generated method stub
        return null;
    }

    protected void onPostExecute(Void result) {
        Log.d(TAG, " post execute async");
        mDialog.dismiss();
    }

}

Problem

I can get a progress bar to appear with the following code ``` pd = ProgressDialog.show(myActivity.this, "", "Loading. Please wait...", true); ``` straight forward, but once I have the code execute I want it to go away, but when I run the dismiss method after I never see the dialog box show at all. Heres the code in context which is wrapped in oncreate ``` pd = ProgressDialog.show(myActivity.this, "", "Loading. Please wait...", true); runCode(); setListAdapter(new CustomAdapter(myActivity.this)); pd.dismiss(); ``` I thought you can show/dismiss progress dialog's anywhere in the activity but I must be wrong.
