Android Progress Bar Not Showing

ok so what am i missing here? i am trying to start a circular progress bar in a button press and stop it after methods finish the progress bar does not display at all or displays o

Solution 1:

Please try running getVcardString() function in a different thread. Once you are completed with that function, use a handler and run the visibilty change of progress bar from there.

Something Like :

pro.setVisibility(View.VISIBLE);
    new Thread(new Runnable() {
        @Override
        public void run() {
            getVcardString();
        }
    }).start();

Then from getVcardString() function :

privatevoidgetVcardString(){
    ....

    newHandler(Looper.getMainLooper()).post(newRunnable() {
        @Overridepublicvoidrun() {
            pro.setVisibility(View.GONE);
        }
    });
}
