Question

I am developing a sample application with TabHost, which is containing HorizontalScrollView. Here is my problem:

• I have more than 10 tabs, when i click on any of the tabs it should set the gravity as center? How i can over come this issue.

Thanks in advance!!!

Answer 1

This will involve some calculation.

Bsically you will need to scroll to the position to center a element.

int scrollX = (button.getLeft() - (screenWidth/2))+(button.getWidth()/2);
hScrollView.scrollTo(scrollX,0);

Where the

button -> It is the button you are trying to center.

screenWidth -> Width of the screen.
int screenWidth = getWindowManager().getDefaultDisplay().getWidth();

hScrollView -> It is the horizontal scrollview.

But even with this method, you will not be able to center the end elements as scrollviews will not scroll beyond its bounds.
