我是使用片段动画的新手,现在我正面临一个问题.我尝试将动画添加到片段事务中.但是,当我在事务仍在进行时尝试单击按钮时,它们正在工作,应用程序崩溃.我该如何避免这种情况？这是我的代码:
FragmentManager fragmentManager =getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.setCustomAnimations(R.anim.enter_from_left, R.anim.exit_to_right);
fragmentTransaction.replace(R.id.container_body, fragmentMain);
fragmentTransaction.commit();
错误:
