多次刷新后，会出现Tab文字不显示的bug！

[liuwen370494581]

public void setNavigator(IPagerNavigator navigator) {
    if (mNavigator == navigator) {
        return;
    }
    if (mNavigator != null) {
        mNavigator.onDetachFromMagicIndicator();
    }
    mNavigator = navigator;
    removeAllViews();
    if (mNavigator instanceof View) {
        LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
        addView((View) mNavigator, lp);
        mNavigator.onAttachToMagicIndicator();
    }
}

根据debug 多次调用这个方法后 必出现文字不显示的bug！如果吧 removeAllViews(); 这个方法注释 则不会 不知道哪里出了问题

因为是做了下拉刷新，所以会多次调用setNavigator（）这个方法，麻烦有知道的朋友解决一下 谢谢了

   TabFragmentAdapter mTabFragmentAdapter = new TabFragmentAdapter(getChildFragmentManager(), roomDevice);
