 > this code gives nullpointerexception

Move your setContentView() statement to be just under the super.onCreate()
statement.

You are attempting to find a widget (findViewById()) before the widget
exists (setContentView()).

If that does not help, could you let us know what line is causing the
exception?

for some reason the append caused this issue.

2. Pass event to parent view?

I have a layout which contains five TextView. When user clicks any of
the five TextView, it will do the same thing: open another activity.
So, the OnClickerListener behavior to the five TextView is the same.
Is it possible that I only add OnClickListerner to one view, e.g. to
layout, so I don't have to add OnClickListerner to each of the five
TextView? Put it another way, if none of the children components
receives CLICK event, will the CLICK event passed through to their
parent, the layout?
