ActionBar-PullToRefreshLibs+沉浸式在部分手机上的布局错乱,目前知道的三星

前段时间看见ActionBar-PullToRefreshLibs用来刷新很好看，配合4.4以上支持的沉浸式效果更佳，于是便想配合沉浸式+ActionBar-PullToRefreshLibs做出一个效果，在自己的大神F2手机上看见没有问题，但是在三星note3上却出现了下拉actionbar刷新和actionbar错位的情况，非常郁闷。通过调试ActionBar-PullToRefreshLibs发现状态栏在设置沉浸式的时候在三星机器上的高度被抹了（rect.top=0）,于是手动修改了ActionBar-PullToRefreshLibs的内部方法，实现了部分机器上的沉浸式+ActionBar-PullToRefreshLibs效果。修改原理是判断rect.top是否为0，如果为0就手动获取状态栏的高度给rect设置top，修改代码如下：

 protected void addHeaderViewToActivity(View headerView) {
         // Get the Display Rect of the Decor View
         mActivity.getWindow().getDecorView()
                 .getWindowVisibleDisplayFrame(mRect);
 5         if (mRect.top == 0)
 6             mRect.top = getStatusBarHeight(mActivity);
         // Honour the requested layout params
         int width = WindowManager.LayoutParams.MATCH_PARENT;
         int height = WindowManager.LayoutParams.WRAP_CONTENT;
         ViewGroup.LayoutParams requestedLp = headerView.getLayoutParams();
         if (requestedLp != null) {
             width = requestedLp.width;
             height = requestedLp.height;
         }

         // Create LayoutParams for adding the View as a panel
         WindowManager.LayoutParams wlp = new WindowManager.LayoutParams(width,
                 height, WindowManager.LayoutParams.TYPE_APPLICATION_PANEL,
                 WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
                         | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE
                         | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
                 PixelFormat.TRANSLUCENT);
         wlp.x = 0;
         wlp.y = mRect.top;
         wlp.gravity = Gravity.TOP;

         // Workaround for Issue #182
         headerView.setTag(wlp);
         mActivity.getWindowManager().addView(headerView, wlp);
     }

     protected void updateHeaderViewPosition(View headerView) {
         // Refresh the Display Rect of the Decor View
         mActivity.getWindow().getDecorView()
                 .getWindowVisibleDisplayFrame(mRect);
36         if (mRect.top == 0)
37             mRect.top = getStatusBarHeight(mActivity);
         WindowManager.LayoutParams wlp = null;
         if (headerView.getLayoutParams() instanceof WindowManager.LayoutParams) {
             wlp = (WindowManager.LayoutParams) headerView.getLayoutParams();
         } else if (headerView.getTag() instanceof WindowManager.LayoutParams) {
             wlp = (WindowManager.LayoutParams) headerView.getTag();
         }

         if (wlp != null && wlp.y != mRect.top) {
             wlp.y = mRect.top;
             mActivity.getWindowManager().updateViewLayout(headerView, wlp);
         }
     }

添加获取状态栏高度的方法

 /**
      * 获取状态栏高度
      *
      * @return
      */
     protected int getStatusBarHeight(Context context) {
         int result = 0;
         int resourceId = context.getResources().getIdentifier(
                 "status_bar_height", "dimen", "android");
         if (resourceId > 0) {
             result = context.getResources().getDimensionPixelSize(resourceId);
         }
         return result;
     }

运行效果图如下：

需要注意的地方：actionbar我没有用开源的第三方组件，也没有用自带的actionbar，而是把隐藏了title在封装的基类中自定义布局的actionbar。
