Android 为TV端助力之解决ViewPager嵌套RecyclerView水平滑动问题

public class MyViewPager extends ViewPager {    private RecyclerView recyclerView;    public MyViewPager(@NonNull Context context) {        super(context);    }    public MyViewPager(@NonNull Context context, @Nullable AttributeSet attrs) {        super(context, attrs);    }   public void setView(RecyclerView recyclerView){        this.recyclerView = recyclerView;   }    private int startX, startY;    @Override    public boolean onInterceptTouchEvent(MotionEvent ev) {        if(null != recyclerView){            switch (ev.getAction()) {                case MotionEvent.ACTION_DOWN:                    startX = (int) ev.getX();                    startY = (int) ev.getY();                    getParent().requestDisallowInterceptTouchEvent(true);                    break;                case MotionEvent.ACTION_MOVE:                    int endX = (int) ev.getX();                 //第一种方法//                    int endY = (int) ev.getY();//                    int disX = Math.abs(endX - startX);//                    int disY = Math.abs(endY - startY);//                    if(disX > disY){//                        getParent().requestDisallowInterceptTouchEvent(canScrollHorizontally(startX -endX));//                    }else {//                        getParent().requestDisallowInterceptTouchEvent(canScrollVertically(startY -endY));//                    }                                        //第二种方法                    if(endX>startX){ //表示向左滑动                        isVisTop(recyclerView);                    }else if(endX<startX){//向右滑动                        isVisBottom(recyclerView);                    }                    break;                case MotionEvent.ACTION_UP:                case MotionEvent.ACTION_CANCEL:                    getParent().requestDisallowInterceptTouchEvent(false);                    break;            }            return super.onInterceptTouchEvent(ev);        }else{            return super.onInterceptTouchEvent(ev);        }    }    public static boolean isVisBottom(RecyclerView recyclerView){        LinearLayoutManager layoutManager = (LinearLayoutManager) recyclerView.getLayoutManager();        //屏幕中最后一个可见子项的position        int lastVisibleItemPosition = layoutManager.findLastVisibleItemPosition();        //当前屏幕所看到的子项个数        int visibleItemCount = layoutManager.getChildCount();        //当前RecyclerView的所有子项个数        int totalItemCount = layoutManager.getItemCount();        //RecyclerView的滑动状态        int state = recyclerView.getScrollState();        if(visibleItemCount > 0 && lastVisibleItemPosition == totalItemCount - 1 ){            return true;        }else {            return false;        }    }    public static boolean isVisTop(RecyclerView recyclerView){        LinearLayoutManager layoutManager = (LinearLayoutManager) recyclerView.getLayoutManager();        //屏幕中最后一个可见子项的position        int lastVisibleItemPosition = layoutManager.findLastVisibleItemPosition();        //当前屏幕所看到的子项个数        int visibleItemCount = layoutManager.getChildCount();        //当前RecyclerView的所有子项个数        int totalItemCount = layoutManager.getItemCount();        //RecyclerView的滑动状态        int state = recyclerView.getScrollState();        if(visibleItemCount > 0 && lastVisibleItemPosition <visibleItemCount){            return true;        }else {            return false;        }    }}

重新viewPager拦截器onInterceptTouchEvent方法，如上面所示，滑动最左边或者最右边的时候就返回true拦截监听，交给viewPager自己处理，如果不是那就返回false，向下传递
