从android中更改特定选项卡的选项卡图标

MainActivity是一个操作栏选项卡Swipe fragmentactivity，包含5个片段。如何在不影响其他选项卡图标的情况下更改特定选项卡图标（例如，在滑动到位置3时第3个位置的图标）。tabs.setIcon（）可以工作，但当滑动到其他位置时，选项卡图标会更改为上一个位置。有没有办法从fragment中只更改特定的选项卡图标

仅将此选择器用于第三个tab.ok，但spec.setIndicator（“HOME”，setImageResource（R.drawable.HOME））用于tabhostR.drawable.HOME是一个选择器，它会有所帮助。
