本文介绍了解决在Android应用中ViewPager嵌套WebView时出现的滑动冲突问题的方法。通过为WebView添加触摸监听器并调整其父View的触摸事件拦截逻辑，实现了WebView水平滑动时ViewPager不会误触发切换。

viewpager 嵌套 webview ，当webview内容过宽，左右滑动与viewpager冲突，解决方法，给webview加上touch消息监听

private final class WebViewOnTouchListener implements OnTouchListener{

       int startX = 0;
       int startY = 0;

       @Override
       public boolean onTouch(View v, MotionEvent event) {
           int xDistance = 0;
           int yDistance = 0;
           switch (event.getAction()) {
           case MotionEvent.ACTION_DOWN:
               startX = (int) event.getRawX();
               startY = (int) event.getRawY();
               break;
           case MotionEvent.ACTION_MOVE:
               xDistance = (int) (event.getRawX() - startX);
               yDistance = (int) (event.getRawY() - startY);

               Point outSize = new Point();    ///*****用这种方法可以得到屏幕的真实宽高
               ((Activity)context).getWindowManager().getDefaultDisplay().getRealSize(outSize);
               int screenWidth = outSize.x;
               int screenHeight = outSize.y;


               int xStardar = screenWidth / 3;
               int yStardar = screenHeight / 16;
               if(Math.abs(xDistance) < xStardar){
                   holder.wv_table_content.getParent().getParent().getParent().requestDisallowInterceptTouchEvent(true); // viewpager不允许拦截touch消息
                   if(Math.abs(yDistance) > yStardar){
                       holder.wv_table_content.getParent().getParent().getParent().requestDisallowInterceptTouchEvent(false);
                       holder.wv_table_content.setHorizontalScrollBarEnabled(false);
                   }
               }else{
                   holder.wv_table_content.getParent().getParent().getParent().requestDisallowInterceptTouchEvent(false);
                   holder.wv_table_content.setHorizontalScrollBarEnabled(false);
               }
               break;
           case MotionEvent.ACTION_UP:
               holder.wv_table_content.getParent().getParent().getParent().requestDisallowInterceptTouchEvent(false);
               holder.wv_table_content.setHorizontalScrollBarEnabled(true);
               break;
           default:
               break;
           }
           return false;
       }
   }
