I have no idea how to fix it -.-

Answer 1

The ListView's height is MATCH_PARENT which constrains it to the height of its parent ViewGroup. You should always define the height of scrollable views like ListView as WRAP_CONTENT so that it can freely expand according to the number of children. Also it might be a good idea for the parent LinearLayout to be anchored to the top of the RelativeLayout: android:layout_alignParentTop="true". Leaving views floating freely in RelativeLayouts may have surprising consequences.
