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：

 1 protected void addHeaderViewToActivity(View headerView) {

 2         // Get the Display Rect of the Decor View

 3         mActivity.getWindow().getDecorView()

 4                 .getWindowVisibleDisplayFrame(mRect);

 5         if (mRect.top == 0)

 6             mRect.top = getStatusBarHeight(mActivity);

 7         // Honour the requested layout params

 8         int width = WindowManager.LayoutParams.MATCH_PARENT;

 9         int height = WindowManager.LayoutParams.WRAP_CONTENT;

10         ViewGroup.LayoutParams requestedLp = headerView.getLayoutParams();

11         if (requestedLp != null) {

12             width = requestedLp.width;

13             height = requestedLp.height;

14         }

15 

16         // Create LayoutParams for adding the View as a panel

17         WindowManager.LayoutParams wlp = new WindowManager.LayoutParams(width,

18                 height, WindowManager.LayoutParams.TYPE_APPLICATION_PANEL,

19                 WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE

20                         | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE

21                         | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,

22                 PixelFormat.TRANSLUCENT);

23         wlp.x = 0;

24         wlp.y = mRect.top;

25         wlp.gravity = Gravity.TOP;

26 

27         // Workaround for Issue #182

28         headerView.setTag(wlp);

29         mActivity.getWindowManager().addView(headerView, wlp);

30     }

31 

32     protected void updateHeaderViewPosition(View headerView) {

33         // Refresh the Display Rect of the Decor View

34         mActivity.getWindow().getDecorView()

35                 .getWindowVisibleDisplayFrame(mRect);

36         if (mRect.top == 0)

37             mRect.top = getStatusBarHeight(mActivity);

38         WindowManager.LayoutParams wlp = null;

39         if (headerView.getLayoutParams() instanceof WindowManager.LayoutParams) {

40             wlp = (WindowManager.LayoutParams) headerView.getLayoutParams();

41         } else if (headerView.getTag() instanceof WindowManager.LayoutParams) {

42             wlp = (WindowManager.LayoutParams) headerView.getTag();

43         }

44 

45         if (wlp != null && wlp.y != mRect.top) {

46             wlp.y = mRect.top;

47             mActivity.getWindowManager().updateViewLayout(headerView, wlp);

48         }

49     }

 

添加获取状态栏高度的方法

 1 /**

 2      * 获取状态栏高度

 3      * 

 4      * @return

 5      */

 6     protected int getStatusBarHeight(Context context) {

 7         int result = 0;

 8         int resourceId = context.getResources().getIdentifier(

 9                 "status_bar_height", "dimen", "android");

10         if (resourceId > 0) {

11             result = context.getResources().getDimensionPixelSize(resourceId);

12         }

13         return result;

14     }

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。
