java代碼編寫shape文件和狀態選擇器

1. //獲取一個shape對象
2. public static GradientDrawable getGradientDrawable(int color, int radius) {
3. // xml中定義的shape標籤 對應此類
4. GradientDrawable shape = new GradientDrawable();
5. shape.setShape(GradientDrawable.RECTANGLE);// 矩形
6. shape.setCornerRadius(radius);// 圓角半徑
7. shape.setColor(color);// 顏色
9. return shape;
10. }
12. //獲取狀態選擇器
13. public static StateListDrawable getSelector(Drawable normal, Drawable press) {
14. StateListDrawable selector = new StateListDrawable();
15. selector.addState(new int[] { android.R.attr.state_pressed }, press);// 按下圖片
16. selector.addState(new int[] {}, normal);// 默認圖片
18. return selector;
19. }
21. //獲取狀態選擇器
22. public static StateListDrawable getSelector(int normal, int press, int radius) {
23. GradientDrawable bgNormal = getGradientDrawable(normal, radius);
24. GradientDrawable bgPress = getGradientDrawable(press, radius);
25. StateListDrawable selector = getSelector(bgNormal, bgPress);
26. return selector;
27. }
