  • Shape + Selector: Make a Shape as one item of the Selector

    Generally, I use a selector to select pictures or colors to render the normal and the pressed background for View.

    And use a Shape to draw a fixed background with border, round, gradient and other UI effect for View.

    What if you wanna use them both for one View?

    Make a Shape as one item of the Selector.

    Selector selects background from Shape list.

    Below is a sample.

                      <stroke android:width=”@dimen/gap_2″ android:color=”@color/linecolor” />

             </shape>  
         </item>  
    </selector>
