private TabLayout    tabMain;

@Override

protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

                setContentView(R.layout.activity_main);

                        initView();

}

private void initView() {

                tabMain = (TabLayout) findViewById(R.id.tab_main);

                //添加下面这条就可以解决TabLayout菜单图标灰白的问题

                tabMain.setTabIconTint(null);

}

===================================

就这么的简单。
