Java 如果在动画进行过程中单击，Android片段事务动画将崩溃

我不熟悉使用片段动画，现在我面临一个问题。我尝试向片段事务添加动画。然而，当我试图在事务仍在进行时单击按钮时，应用程序崩溃了。我如何避免这种情况？这是我的密码：

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：

尝试以下代码：

FragmentTransaction mFragmentTransaction = getFragmentManager().beginTransaction();
mFragmentTransaction.setCustomAnimations(R.animator.enter_anim, R.animator.exit_anim);
mFragmentTransaction.replace(R.id.listFragment, new YourFragment());
mFragmentTransaction.commit();

<?xml version="1.0" encoding="utf-8"?>
    <set>
    <objectAnimator
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:propertyName="x"
    android:valueFrom="2000"
    android:valueTo="0"
    android:valueType="floatType" />
    </set>

片段开始动画：

FragmentTransaction mFragmentTransaction = getFragmentManager().beginTransaction();
mFragmentTransaction.setCustomAnimations(R.animator.enter_anim, R.animator.exit_anim);
mFragmentTransaction.replace(R.id.listFragment, new YourFragment());
mFragmentTransaction.commit();

<?xml version="1.0" encoding="utf-8"?>
    <set>
    <objectAnimator
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:propertyName="x"
    android:valueFrom="2000"
    android:valueTo="0"
    android:valueType="floatType" />
    </set>

片段结束动画

<?xml version="1.0" encoding="utf-8"?>
    <set>
    <objectAnimator
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:propertyName="x"
    android:valueFrom="0"
    android:valueTo="-2000"
    android:valueType="floatType" />
    </set>

希望它能帮助您使用透明片段动画。

您在模拟器上测试过吗？请在启用连接的真实设备上重试。@EdwardBishop您是否找到了导致此问题的原因/修复方法？我也遇到同样的问题。
