在style.xml中添加：

 <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowAnimationStyle">@style/activityAnimation</item>
    </style>

 <!-- animation 样式 -->
    <style name="activityAnimation" parent="@android:style/Animation">
        <item name="android:activityOpenEnterAnimation">@anim/slide_right_in</item>
        <item name="android:activityOpenExitAnimation">@anim/slide_left_out</item>
        <item name="android:activityCloseEnterAnimation">@anim/slide_left_in</item>
        <item name="android:activityCloseExitAnimation">@anim/slide_right_out</item>
    </style>

配置文件anim文件：

    <translate android:duration="300" android:fromXDelta="-100.0%p" android:toXDelta="0.0" />
</set>
