这个跟TabLayout库无关.
不要在全局变量初始化中,使用getResource方法

  private String[] mTitles;
  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_common_tab);

        mTitles = new String[]{getResources().getString(R.string.xxx), ...};
}

为什么不能在oncreate中使用getResource()？

能在oncreate中使用getResource(),不要在全局变量定义的地方使用.
此时Activity还没创建,context拿不到为null
