Android圆环形颜色选择器：HoloColorPicker

HoloColorPicker实现圆环形颜色选择器，可以改变颜色饱和度来选择颜色。选择颜色时，可以用手指沿着圆环滑动一个滑块，从而选择颜色。

添加以下XML至你的布局中：

?

1 2 3 4

<com.larswerkman.holocolorpicker.ColorPicker     android:id="@+id/picker"     android:layout_width="wrap_content"     android:layout_height="wrap_content"/>

To add a Saturation/Value bar to your layout add this to your xml

?

1 2 3 4

<com.larswerkman.holocolorpicker.SVBar     android:id="@+id/svbar"     android:layout_width="wrap_content"     android:layout_height="wrap_content"/>

The same goes for the Opacity bar

?
