Android自定义滑动解锁控件使用详解

最近的项目里用到了,在网上找不到合适的,于是自己写了个简单的,带回弹效果:

可以自定义的属性有:

<!-- 滑动解锁控件 xml配置属性 -->
<declare-styleable name="SlideToUnlockView">
 <attr name="slideImageViewWidth" format="dimension"/><!-- 滑块宽度 -->
 <attr name="slideImageViewResId" format="reference"/><!-- 滑块资源id -->
 <attr name="slideImageViewResIdAfter" format="reference"/><!-- 滑动到右边时,滑块资源id -->
 <attr name="viewBackgroundResId" format="reference"/><!-- 背景资源id -->
 <attr name="textHint" format="string"/><!-- 文本内容 -->
 <attr name="textSize" format="integer"/><!-- 文本字号 -->
 <attr name="textColorResId" format="color"/><!-- 文本字色 -->
 <attr name="slideThreshold" format="float"/><!-- 滑动阈值,默认是0.5,当右滑距离不满整个控件宽度的0.5,就会回弹至左边 -->
</declare-styleable>
