Activity 右进右出动画；（解决右进有效，右出无效BUG）

Mark

1、定义动画

slide_left_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="300"
android:fromXDelta="-100.0%p"
android:toXDelta="0.0" />
</set>slide_left_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="300"
android:fromXDelta="0.0"
android:toXDelta="-100.0%p" />
<alpha android:fromAlpha="1.0" android:toAlpha="1.0"
android:duration="300" />
</set>

slide_right_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="300"
android:fromXDelta="100.0%p"
android:toXDelta="0.0"/>
<alpha
android:duration="300"
android:fromAlpha="1.0"
android:toAlpha="1.0"/>
</set>

slide_right_out.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="300"
android:fromXDelta="0.0"
android:toXDelta="100.0%p"/>
<alpha
android:duration="300"
android:fromAlpha="1.0"
android:toAlpha="1.0"/>
</set>

2、

<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>
<style name="Animation_RightInRightOutActivity" parent="@style/Theme.AppCompat.NoActionBar">
<item name="android:windowAnimationStyle">@style/activityAnimation</item>
</style>

3、

<activity
android:name=".activity.VideoDetailActivity"
android:theme="@style/Animation_RightInRightOutActivity"></activity>

以上代码，经测试，进入Activity有效果，但是退出Activity时候没有效果：下面解决方案
在BaseActivity中

定义全局变量：

protected int activityCloseEnterAnimation;
protected int activityCloseExitAnimation;

然后在onCreate中调用以下方法：

private void initAnim() {
TypedArray activityStyle = getTheme().obtainStyledAttributes(new int[]{android.R.attr.windowAnimationStyle});

int windowAnimationStyleResId = activityStyle.getResourceId(0, 0);

activityStyle.recycle();

activityStyle = getTheme().obtainStyledAttributes(windowAnimationStyleResId, new int[]{android.R.attr.activityCloseEnterAnimation, android.R.attr.activityCloseExitAnimation});

activityCloseEnterAnimation = activityStyle.getResourceId(0, 0);

activityCloseExitAnimation = activityStyle.getResourceId(1, 0);

activityStyle.recycle();
}

重新finish方法：

@Override
public void finish() {
super.finish();
overridePendingTransition(activityCloseEnterAnimation, activityCloseExitAnimation);
}

问题解决
