Romain Guy write a little info about a ScrollView attribute that is missing from documentation :android:fillViewport=”true” .
It must be set to ScrollView and has the following efect : when set to true, this attribute causes the scroll view’s child to expand to the height of the ScrollView
if needed. When the child is taller than the ScrollView
, the attribute has no effect.
当你想让一个高度值不足scrollview的子控件fillparent的时候,单独的定义android:layout_height="fill_parent"是不起作用的,必须加上fillviewport属性,当子控件的高度值大于scrollview的高度时,这个标签就没有任何意义了。
看上面的解释,不多说了,留一个记录!
当ScrollVIew中 有直接的图片的时候,下面一般会有空白,这个时候要加上 android:fillViewport=”true” . 下面就不会有空白了!
