Latested Change Log: (2.0.0)

Some attributes are changed and you need to update them to the new ones, since the measurement logic has been totally changed. (Default behavior and style does not change.)

1. Re-clarify the meaning of some params.
2. Update the measurement of SwitchButton and the logic becomes more clear, especially the text part.
3. Support config SwitchButton's size by setting a exact width and height. There are now TWO mainly method to control it's size.
4. When use SwitchButton in a scrollable view, SwitchButton consume scroll gestures only horizontal. This means the when you want to scroll the scrollable view vertically and start your touch on a SwitchButton, it will not stop you now.
5. Bug fix.

There is a big diagram below to show how SwitchButton measure it self in 2.0.0. It is strongly recommended that you should check it out.

1. kswBackMeasureRatio has been removed from SwitchButton attributes since it has an ambiguous meaning. I've add the new kswThumbRangeRatio attribute to represent how much multiple the scroll range of thumb than the width of thumb.
2. kswTextMarginH and kswAutoAdjustTextPosition have been removed from SwitchButton attributes since I updated the measurement logic of text part. And these two attributes do not represent the back meaning well. kswTextThumbInset, kswTextExtra and kswTextAdjust was introduced to represent "how much the text go under thumb", "how much extra space do you want around the text" and "how much to move the text from the center of text area to adjust the text's position". There are all shown on the diagram.
3. Setters and getters are also changed due to the change of attributes.

This diagram shows how SwitchButton measure itself and what does those nouns mean. To measure width is much complex than the height, so if you know how to measure width, you know how to measure height. And text measurement and location increase the complexity.

I create a new demo apk to show you how to style the cute widget and use it. There's some screenshots of the new demo.

The usage of SwitchButton is just like CheckBox. The basic control APIs of SwitchButton.

• setChecked(boolean)
• toggle()

Since SwitchButton has addition animation when checked status changed, there are two addition methods for disable animation for single operation.

• setCheckedImmediately(boolean): like setChecked but NO animation.
• toggleImmediately(): like toggle but NO animation.

From version 1.4.1 on, SwitchButton support operation without onCheckedChanged callback. It makes changing state in code more convenient. Using these methods to achieve that feature.

• setCheckedNoEvent(boolean)
• setCheckedImmediatelyNoEvent(boolean)
• toggleNoEvent()
• toggleImmediatelyNoEvent()

In 1.3.0, I updated the usage of SwitchButton library. To make it more Android way to use, I've combined the thumb and back style each to StateListColor/StateListDrawable. So you are free to create styles in different states.

In xml layout file, you can configure the face of switch button using these attrs.

• kswThumbDrawable: drawable for thumb
• kswThumbColor: color for thumb
• kswThumbMargin: margin from thumb to back, can be negative. maybe cover by single direction margins
• kswThumbMarginTop: same to kswThumbMargin, just top
• kswThumbMarginBottom: same to kswThumbMargin, just bottom
• kswThumbMarginLeft: same to kswThumbMargin, just left
• kswThumbMarginRight: same to kswThumbMargin, just right
• kswThumbWidth: width of thumb
• kswThumbHeight: height of thumb
• kswThumbRadius: radius of thumb rect, only work with kswThumbColor
• kswBackRadius: radius of background rect, only work with kswBackColor
• kswBackDrawable: drawable for background
• kswBackColor: color for background
• kswFadeBack: fade background color/drawable when drag or animate between on/off status or not
• kswAnimationDuration: duration of animation between 2 status
• kswTintColor: change SwitchButton's style just by one property, all relevant color will be generate automatically. Do not support SwitchButtonMD or other style created by xml resources.
• kswTextOn: text for checked status.
• kswTextOff: text for unchecked status.
• kswTextThumbInset (since 2.0.0): length of the part of text under the thumb.
• kswTextExtra (since 2.0.0): extra space needed by background besides the actual text width.
• kswTextAdjust (since 2.0.0): move the text after position text on the center of text area.
• kswThumbRangeRatio (since 2.0.0): (thumb move range width / thumb's width). float value. see measure diagram
• kswBackMeasureRatio: (background's width / thumb's width). float value. Removed since 2.0.0
• kswTextMarginH: horizontal margin of text. Removed since 2.0.0
• kswAutoAdjustTextPosition: (since 1.4.4) whether auto adjust text position to make them looks centered (NOT really centered) when there are round corners. You should set this to false when you don't need this feature. Removed since 2.0.0

You can alse change the configuration of SwitchButton in code. You can find the api from Demo apk. There's a glance.

private String[] opts = new String[]{
			"setThumbColorRes/setThumbColor",
			"setThumbDrawableRes/setThumbDrawable",
			"setBackColorRes/setBackColor",
			"setBackDrawableRes/setBackDrawable",
			"setTintColor",
			"setThumbMargin",
			"setThumbSize",
			"setThumbRadius (color-mode only)",
			"setBackRadius (color-mode only)",
			"setFadeBack",
			"setBackMeasureRatio",
			"setAnimationDuration",
			"setDrawDebugRect",
			"setText",
	};

If you're using SwitchButton in your app, wish you can email me these infomation of your app and I'll create a list here. And that should be an utmost encouragement to me. :-) [email protected]
