当我使用动画（slide_in和slide_out）时，屏幕消失之前消失
我正在使用视图动画在两个片段main_screen到login_screen之间进行动画过渡。它可以正常运行，但是我只有一个问题，当前屏幕会消失，然后消失，如下所示。
在这里您可以看到，当我转到另一个屏幕时，主屏幕的一半消失了。
这是我的动画的xml文件： 1）slide_in_left
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator"
android:shareInterpolator="false"
>
<translate
android:fillAfter="true"
android:duration="@android:integer/config_mediumAnimTime"
android:fromXDelta="-100%p"
android:toXDelta="0" />
</set>
2）slide_in_right：
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator"
android:shareInterpolator="false"
>
<translate
android:fillAfter="true"
android:duration="@android:integer/config_mediumAnimTime"
android:fromXDelta="100%p"
android:toXDelta="0" />
</set>
3）slide_out_left：
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator"
android:shareInterpolator="false"
>
<translate
android:fillAfter="true"
android:duration="@android:integer/config_mediumAnimTime"
android:fromXDelta="0"
android:toXDelta="-100%p" />
</set>
4）slide_out_right：
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator"
android:shareInterpolator="false"
>
<translate
android:fillAfter="true"
android:duration="@android:integer/config_mediumAnimTime"
android:fromXDelta="0"
android:toXDelta="100%p" />
</set>
