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(PullToRefreshAttacher类中),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);
        if (mRect.top == 0)
            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);
        if (mRect.top == 0)
            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:

技术分享

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。
