选项卡图标在恢复活动时缩小

Question

如何在从其他活动恢复时保持标签图标处于正常阶段？

这是用于标签布局的代码：

public void initViews(View v) {
    //Adding toolbar to the activity
    //Initializing the tablayout
    tabLayout = (TabLayout) v.findViewById(R.id.tabLayout);
    db = new DatabaseHandler(getActivity());
    userid = Util.getUserObject(getActivity(), Constants.KEY_ID);

    //Adding the tabs using addTab() method
    tabLayout.setupWithViewPager(viewPager);
    tabLayout.addTab(tabLayout.newTab());
    tabLayout.addTab(tabLayout.newTab());
    tabLayout.addTab(tabLayout.newTab());
    tabLayout.getTabAt(0).setCustomView(prepareTabItem(0, R.drawable.home_selector));
    tabLayout.getTabAt(1).setCustomView(prepareTabItem(1, R.drawable.message_selector));
    tabLayout.getTabAt(2).setCustomView(prepareTabItem(2, R.drawable.cmnt_selector));
    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
    viewPager = (ViewPager) v.findViewById(R.id.pager);
    menu = (LinearLayout) v.findViewById(R.id.menu);
    search = (LinearLayout) v.findViewById(R.id.search);
    searchIcon = (ImageView) v.findViewById(R.id.search_icon);
    searchIcon.setTag("0");
    mainLayout = (RelativeLayout) v.findViewById(R.id.main_layout);
}
