实现说明:
通过自定义布局实现:
SlidingLayout继承于 HorizontalScrollView
/** * Created by Administrator on 2017/3/29. */ public class SlidingLayout extends HorizontalScrollView{ /** 左侧右边间距 */ private float rightPadding; /** 左侧菜单的宽度 */ private int leftWidth; private ViewGroup leftView; private ViewGroup contentView; private final Context context; private boolean isOpenMeun = true; private ImageView shadowView; public SlidingLayout(Context context) { this(context,null); } public SlidingLayout(Context context, AttributeSet attrs) { this(context, attrs,0); } public SlidingLayout(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); this.context = context; //获取自定义的属性 TypedArray typedArray=context.obtainStyledAttributes(attrs,R.styleable.SlidingLayout); rightPadding=typedArray.getDimension(R.styleable.SlidingLayout_rightPadding,80); //计算左侧菜单的宽度 leftWidth = (int) (getScreenWidth() - rightPadding + 0.5f); } //获取屏幕的宽度 private float getScreenWidth() { return getResources().getDisplayMetrics().widthPixels; } @Override /** 布局解析完毕的时候 */ protected void onFinishInflate() { super.onFinishInflate(); ViewGroup container= (ViewGroup) getChildAt(0); if(container.getChildCount() > 2){ throw new IllegalStateException("SlidingLayout中只能放两个子View"); } //获取左侧菜单view leftView = (ViewGroup) container.getChildAt(0); //获取主布局的Viwe contentView = (ViewGroup) container.getChildAt(1); //设置子view 的宽度 leftView.getLayoutParams().width = leftWidth; contentView.getLayoutParams().width = (int) getScreenWidth(); //移除父布局 container.removeView(contentView); FrameLayout frameLayout=new FrameLayout(context); frameLayout.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT)); frameLayout.addView(contentView); //添加阴影 shadowView = new ImageView(context); shadowView.setBackgroundColor(Color.parseColor("#99000000")); frameLayout.addView(shadowView); container.addView(frameLayout); } /** * 该方法在滑动的时候会不断的调用 * @param l : left * @param t * @param oldl * @param oldt */ @Override protected void onScrollChanged(int l, int t, int oldl, int oldt) { super.onScrollChanged(l, t, oldl, oldt); float x=l*0.8f;//偏移量 leftView.setTranslationX(x);//平移 float color = 1 - l * 1.0f / leftWidth; shadowView.setAlpha(color); } @Override public boolean onTouchEvent(MotionEvent ev) { switch (ev.getAction()) { case MotionEvent.ACTION_UP://手指抬起的时候判断是否关闭 int currentX = getScrollX(); if (isOpenMeun) { if (currentX >= leftWidth / 2) { closeMeun(); } else { openMeun(); } //点击关闭 float x = ev.getX(); if (x > leftWidth) { closeMeun(); } return true; } else {//关闭状态 if (currentX < leftWidth / 2) { openMeun(); } else { closeMeun(); } return true; } } return super.onTouchEvent(ev); } /** 关闭菜单 */ public void closeMeun(){ isOpenMeun = false; smoothScrollTo(leftWidth,0);// 250ms } /** 打开菜单 */ public void openMeun(){ isOpenMeun = true; smoothScrollTo(0,0); } }
