JPSpringMenu

Build Status Android Arsenal Download apm
SpringMenu是一款滑动菜单,类似AndroidResidemenu,SlidingMenu,和其他滑动菜单之间 最大的区别是:它提供的灵活性弹跳，结合了Facebook提供的强大动画库 Rebound

Design Sketch

SpringMenu

Usage

Gradle

dependencies {
    compile 'com.jpeng:jpspringmenu:$latestVersion'
}

在Activity内初始化Menu

    // R.layout.view_menu 是你自定义的Menu View的资源ID
    SpringMenu menu = new SpringMenu(this,R.layout.view_menu);
    
    // 为菜单做各种各样的设置...

不要忘记在Activity重写dispatchTouchEvent

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
         return menu.dispatchTouchEvent(ev);
    }

通过SpringConfig，你可以改变菜单和子布局的弹性速度和力量

    ```
        /*
        另一种方式来构建SpringConfig是frombouncinessandspeed
         friction : 2f -4f 是合适值的范围,太小速度很快,弹性时间长,太大速度会很慢
        friction的值一定不能为0,否则会无限反弹,根据rebound api的定义
        */
    mSpringMenu.setMenuSpringConfig(SpringConfig.fromOrigamiTensionAndFriction(20,3));
    mSpringMenu.setChildSpringConfig(SpringConfig.fromOrigamiTensionAndFriction(20, 5));

如果有滑块控件和菜单的一些冲突，你可以试试addignoreview忽略它们

    mSpringMenu.addIgnoreView(...);

MenuListener可以用来监听菜单事件的变化,里面有三种回调方法:

    //打开后的回调
    void onMenuOpen();
    //关闭后的回调
    void onMenuClose();
    
    /**
     * 当菜单正在被打开或者被关闭时,这个方法将会被回调(包含拖动弧度)
     * @value: 0f-2f,0f表示菜单关闭,2f则表示打开
     * @bouncing: 这个布尔值用来判断菜单是否在反弹状态
     * 当处于反弹状态时,这个值无限趋近于2f,否则就是0f
     */
    void onProgressUpdate(float value,boolean bouncing);

剩余部分较为重要的Api

     // 内容页变暗的效果
     setFadeEnable(boolean);
     
     // 允许菜单开始拖动的距离
     setDragOffset(float);
     
     setDirection(int direction);
