android Progress bar dismissed early

my code:

OnClickListener()//onclicklistener for button
{
    ProgressBar = new ProgressDialog(LoginPageActivity.this);
    ProgressBar.setMessage("please wait..");     
    ProgressBar.show();

    TcpConnection loginConnect = new TcpConnection();//TcpConnection is a class
    loginConnect.run();
    ProgressBar.dismiss();
}

i tried to show progress dialog before calling another class and dismiss it after the call is over. but progressbar will not showing and it dismissed early . but i want to show progress bar for certain period of time.

My guess is that loginConnect.run() is running in its own thread. That's why the progress dialog is being dismissed instantly.

Here's what you should do instead:

class LoginTask extends AsyncTask<Void, Void, Void>{
    ProgressDialog d;
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        d = new ProgressDialog(LoginPageActivity.this);
        d.setMessage("please wait..");     
        d.show();
    }

    @Override
    protected Void doInBackground(Void... params) {
        TcpConnection loginConnect = new TcpConnection();
        loginConnect.run();
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        super.onPostExecute(result);
        d.dismiss();
    }   
}

And in your onClickListener call new LoginTask().execute();

How I understand you need to use threads. Like this

ProgressBar p = new ProgressDialog(LoginPageActivity.this);
Private Handler handler = new Handler();
p.setVisibality(0); //makes visible
    new Thread(new Runnable() {
                   public void run() {
                          TcpConnection loginConnect = new TcpConnection();
                          loginConnect.run();
                          handler.post(new Runnable() {
                                           public void run() {
                                      p.setVisibility(8);//Makes Invisible                      
                                                }
                                              });
                                   }

                  }).start();

I think it will help you

Use AsyncTask to achieve your objective. You can show the progressbar(inside onPreExecute()) until your task gets over(inside doInBackground()) and then you can dismiss it after the task is finished(inside onPostExecute()).
