    I got the answer.Here while i was doing first time the btn click, the child view will added to my parent view dynamically.

    During the second click the i removed previously added child from my parent view and added the new child. So this will updates my content and displays clearly every time when I click the btn.

    I got error in removing the views from my child, now I clear the error by assigning some variables for identifying btn click, whether user clicks it for first time or not. thank you all for your time here and for your answers.
