基于带有SherlockFragmentActivity的TabsAdapter的自定义菜单

Question

我正在尝试使用带有SherlockFragmentActivity的TabsAdapter添加自定义菜单。

目前我有4个标签的标签菜单， 我想添加一个覆盖整个菜单和标签

的自定义图像（标记为绿色圆圈）

知道如何做到这一点？

我找到了解决方案：

向TabsAdapter添加4个标签 将布局边距添加到第二个选项卡：

    Display display = getWindowManager().getDefaultDisplay();
    int width = display.getWidth();
    int heigth = mTabHost.getTabWidget().getChildAt(0).getLayoutParams().height;
    mTabHost.getTabWidget().getChildAt(0).setLayoutParams(new LinearLayout.LayoutParams((width / 5), heigth));
    mTabHost.getTabWidget().getChildAt(1).setLayoutParams(new LinearLayout.LayoutParams((width / 5), heigth));

    View currentView = mTabHost.getTabWidget().getChildAt(1);
    LinearLayout.LayoutParams currentLayout = (LinearLayout.LayoutParams) currentView.getLayoutParams();
    currentLayout.setMargins(0, 0, width / 5, 0);

    mTabHost.getTabWidget().getChildAt(2).setLayoutParams(new LinearLayout.LayoutParams((width / 5), heigth));
    mTabHost.getTabWidget().getChildAt(3).setLayoutParams(new LinearLayout.LayoutParams((width / 5), heigth));
