android-actionbar

问题 So I have 3 actionBar tabs running 3 different fragment classes. In Tab1 of the actionBar I have a simple form that a user fills in and the data is then saved in an SQLite database, this form and the tasks carried out on it work fine as a project by itself but when I tried to integrate it as a fragment (FragmentTab1) then the app crashes when I click the save button. Any ideas as to why it may be crashing? I think I may have to implement an onClickListener maybe, not sure though! I am aware

Your code might look something like this: View tabs = findViewById(R.id.the_tabs_id)
