获取 ViewPager 当前正在展示view方法

直接上代码传入 自己的ViewPager 调用以下方法就可以了

 
  private View getCurrentView(ViewPager viewPager) {
    try {
      final int currentItem = viewPager.getCurrentItem();
      for (int i = 0; i < viewPager.getChildCount(); i++) {
        final View child = viewPager.getChildAt(i);
        final ViewPager.LayoutParams layoutParams = (ViewPager.LayoutParams) child.getLayoutParams();
        Field f = layoutParams.getClass().getDeclaredField("position"); //NoSuchFieldException
        f.setAccessible(true);
        int position = ((Integer) f.get(layoutParams)); //IllegalAccessException
        if (!layoutParams.isDecor && currentItem == position) {
          return child;
        }
      }
    } catch (NoSuchFieldException e) {
    } catch (IllegalArgumentException e) {
    } catch (IllegalAccessException e) {
    }
    return null;
  }

注意要保证页面数据已经加载完毕的时候调用才有效果

比如在 addOnGlobalLayoutListener 回调中调用

view_pager.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {
                    view_pager.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                    	//获取当前显示的页面
                    	View inflate = MyUtils.getCurrentView(view_pager);
                }
            });```
