애니메이션 전환시 잔상이 보이는이유?

Question

slide_in_right.xml

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

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">

<translate android:fromXDelta="50%p" android:toXDelta="0"

android:duration="@android:integer/config_mediumAnimTime"/>

<alpha android:fromAlpha="0.0" android:toAlpha="1.0"

android:duration="@android:integer/config_mediumAnimTime" />

</set>

 

slide_out_left.xml

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

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">

<translate android:fromXDelta="0" android:toXDelta="-50%p"

android:duration="@android:integer/config_mediumAnimTime"/>

<alpha android:fromAlpha="1.0" android:toAlpha="0.0"

android:duration="@android:integer/config_mediumAnimTime" />

</set>

 

overridePendingTransition(android.R.anim.slide_in_left, R.anim.slide_out_left);

 

overridePendingTransition(R.anim.slide_in_right, R.anim.slide_out_left);

 

 

위처럼 하고 잇는데요 화면전환시 두 화면이 겹치듯이 잔상이 보입니다

어떻게 하면 잔상이 보이지 않을까요?
