I am trying to make a tab bar application in android, after searching in google i found some tutorial and i succeeded. I want 3 tabs, when i click on 1st tab some data will be taken from server using asyntask and show the progressdialog in frontend, but the progressdialog is capturing the whole screen(with tabbar) and because of that i can't be able to switch the 2nd or 3rd tab.
Expected Output: Whenever i click on any tab a data will be taken from server in background, as i know data is loaded in background so for that time i want to switch 2nd tab or any other tab.
