The Android:fillviewport in ScrollView is set to true using the ScrollView nested linearlayout.


When the elements in the ScrollView want to fill ScrollView, using "fill_parent" is not useful and must be set to ScrollView: Android:fillviewport= "true".

When ScrollView does not fillveewport= "true", the elements inside (such as linearlayout) are calculated according to the wrap_content (whether or not it is set to "Fill_parent"), And if the elements of the LinearLayout set fill_parent, then it is no use, because the linearlayout depends on the elements inside, and the elements in the linearlayout, such contradictions. So the inside element is set to Fill_ The parent will also be counted as wrap_content.
