解决办法：

将replace替换为add方法，因为错误原因为： is not currently in the FragmentManager

getSupportFragmentManager()
.beginTransaction()
.replace(R.id.activity_rl_emojicons, emojiconsFragment)
.commit();

getSupportFragmentManager()
.beginTransaction()
.add(R.id.activity_rl_emojicons, emojiconsFragment)
.commit();
