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.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
<?xml version=”1.0″ encoding=”UTF-8″?>
<selector xmlns:android=”http://schemas.android.com/apk/res/android”>
<item android:state_pressed=”true”>
<shape android:shape=”rectangle”>
<solid android:color=”@color/background_pressed” />
<stroke android:width=”@dimen/gap_2″ android:color=”@color/linecolor” />
<padding android:bottom=”@dimen/gap_2″ android:left=”@dimen/gap_2″
android:right=”@dimen/gap_2″ android:top=”@dimen/gap_2″ />
</shape>
</item>
<item>
<shape android:shape=”rectangle”>
<solid android:color=”@color/background_normal” />
<stroke android:width=”@dimen/gap_2″ android:color=”@color/linecolor” />
<padding android:bottom=”@dimen/gap_2″ android:left=”@dimen/gap_2″
