Hi,
Use this code,
new Thread(new Runnable() {
@Override
public void run() {
//GetWts(); //processes some action
try {
sleep(3000);
} catch (Exception e) {
// TODO: handle exception
}
handler.sendEmptyMessage(0);
progressBar.dismiss();
}
}).start();
progressBar.dismiss();
Handler handle=new Handler(){
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
if(msg.what == 0) {
//perform some action here................
}
}
};
