问题
Android L is not able to draw dotted line as drawable background as below:
<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="line" >
<stroke
android:dashGap="1dp"
android:dashWidth="1dp"
android:color="#999999" />
<size android:height="1dp" />
</shape>
</item>
</selector>
I am also using layerType='software' in xml. Kindly help.
回答1:
1.The view must be at least 2dp in height (or wrap_content
), in order for it to display since a stroke is designed to go around the view and it doesn't have room to do so in 1dp.
2.Add width to your xml:
<stroke
android:width="1dp"
android:dashGap="1dp"
android:dashWidth="1dp"
android:color="#999999" />
<size android:height="1dp"
android:width="1dp"/>
3.Use layerType='software'
