AsyncTask:

public class Asyctast extends AsyncTask<Void, Object, Void>
{

 private ProgressDialog dialog = new ProgressDialog(DisplayAtms.this);

   @Override
    protected void onPreExecute() {
        super.onPreExecute();
        runOnUiThread(showProgress);
    }


   @Override
    protected void onProgressUpdate(final Object... args) {
        super.onProgressUpdate(args);
        if ((Boolean) args[0]) {
            Toast.makeText(DisplayAtms.this, args[1].toString(),
                    Toast.LENGTH_LONG).show();
        }
    }

   @Override
    protected Void doInBackground(Void... arg0) {
         Log.d("Asynctask", ""+arg0);  


            publishProgress(true,"sd sdfsdf");


            return null;

    }

@Override
protected void onPostExecute(Boolean result) {
    runOnUiThread(hideProgress);
    }

}


Runnable showProgress = new Runnable() {

        @Override
        public void run() {
            pd = new ProgressDialog(DisplayAtms.this);
            pd = registerDialog(pd);
            pd.show();
        }
};  


Runnable hideProgress = new Runnable() {

        @Override
        public void run() {
            if(pd != null)
            pd.hide();
        }
};

Answer 1

AsyncTask.onPostExecute 没有必要做这样的事情:

Runnable showProgress = new Runnable() {

    @Override
    public void run() {
        pd = new ProgressDialog(DisplayAtms.this); //here is the leak
        pd = registerDialog(pd);
        pd.show();

    }
};

为此:

@Override
protected void onPreExecute() {
    pd.show();
}

@Override 
protected void onPostExecute(Boolean result) {
    pd.dismiss();
}

You can use Handler too:
