android中 layer-list和include的使用

layer-list 看来是图层的累加 我是这么理解的，字面上是多个层，也就是呢你可以把多个leyaer放在一起然后一其显现出来 如qqw.xml

view plaincopy to clipboardprint?
  1. <?xml?version="1.0"?encoding="utf-8"?>??
  2. <layer-list?xmlns:android="http://schemas.android.com/apk/res/android">??
  3. ???<item>??
  4. ??????<shape>??
  5. ?????????<solid?android:color="#FF00ff00"?/>??
  6. ?????????<gradient????
  7. ??????????????????android:useLevel="true"????
  8. ?????????????????android:type="sweep"????
  9. ??????????????????android:startColor="#ff000000"????
  10. ??????????????????android:endColor="#ffff0000"?/>???
  11. ??????</shape>??
  12. ???</item>??
  13. ????<item>????
  14. ????????<rotate????
  15. ???????????android:pivotX="50%"?android:pivotY="50%"????
  16. ????????????android:fromDegrees="0"?android:toDegrees="80"????
  17. ???????????android:drawable="@drawable/icon"?/>????
  18. ????</item>????
  19. ????
  20. </layer-list>??
?

?

然后就可以在别处引用了

view plaincopy to clipboardprint?
  1. <ImageButton?android:id="@+id/btnFindMe"????
  2. ????????android:layout_width="wrap_content"????
  3. ????????android:layout_height="wrap_content"???
  4. ???????android:layout_centerInParent="true"??
  5. ????????android:background="@drawable/qqw"/>??

?

例如在 android:style/Widget.ProgressBar.Large 或者其他的progressbar风格

view plaincopy to clipboardprint?
  1. <mce:style?name="progressBarStyleSmall"?parent="android:style/Widget.ProgressBar.Large"><!--?
  2. <item?name="android:indeterminateDrawable">@drawable/progress</item>?
  3. --></mce:style><style?name="progressBarStyleSmall"?parent="android:style/Widget.ProgressBar.Large"?mce_bogus="1"><item?name="android:indeterminateDrawable">@drawable/progress</item></style>??
  4. <layer-list?xmlns:android="http://schemas.android.com/apk/res/android">??
  5. ???<!--???<item?android:drawable="@android:drawable/progress_circular_background"?/>-->??
  6. ?????<!--??<item>??
  7. ??????
  8. ????
  9. ????????<shape?android:shape="ring"??
  10. ???????????????android:innerRadiusRatio="3.4"??
  11. ???????????????android:thicknessRatio="6.0">??
  12. ????????????<gradient??
  13. ???????????????????android:useLevel="true"??
  14. ???????????????????android:type="sweep"??
  15. ???????????????????android:startColor="#ff000000"??
  16. ???????????????????android:endColor="#ffffffff"?/>??
  17. ????????</shape>??
  18. ??????????
  19. ????????????
  20. ????</item>?-->??
  21. ????<item>??
  22. ????????<rotate??
  23. ????????????android:pivotX="50%"?android:pivotY="50%"??
  24. padding-top: 0px !important; padding-right: 3px !important; padding-bottom: 0px !important; padding-left: 10px !important; border-top-style: none; border-right-style: none; border-bottom-style: no
