Android 关于Activity的跳转和finish时切换页面动画实现

今天沈阳斌子在做APP时，客户的需求变更是在原有的程序上加入跳转页面的动画切换，类似IPhone的左出右进的方式，返回时是相反的效果。我知道用两种方式可以实现这样的效果，一种就是通过在startActivity后执行overridePendingTransition方法进行动画的切换，同样finish也是一样的。下面就是我封装好的方法：

/**
	 * 
	 *  @Description    : 跳转页面的左出和右进的效果
	 *  @Method_Name    : startActivityAnim
	 *  @param activity 
	 *  @return         : void
	 *  @Creation Date  : 2015-1-5 上午10:20:37 
	 *  @version        : v1.00
	 *  @Author         : JiaBin
	 
	 *  @Update Date    : 
	 *  @Update Author  : JiaBin
	 */
	public static void startActivityAnim(Activity activity, Class<?> cla) {
		Intent intent = new Intent();
		intent.setClass(activity, cla);
		activity.startActivity(intent);
		// 设置切换动画，从右边进入，左边退出
		activity.overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);
	}

1.首先在style.xml中声明如下代码：

    <style name="AnimationActivity" parent="@android:style/Animation.Activity">
        <item name="android:activityOpenEnterAnimation">@anim/push_left_in</item>
        <item name="android:activityOpenExitAnimation">@anim/push_left_out</item>
        <item name="android:activityCloseEnterAnimation">@anim/push_right_in</item>
        <item name="android:activityCloseExitAnimation">@anim/push_right_out</item>
    </style>

    <style name="themeSetting">
         <item name="android:windowAnimationStyle">@style/AnimationActivity</item>
    </style>

<activity
            android:name="com.nearprint.MainNewActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait"
            android:theme="@style/themeSetting<span style="font-family: Arial, Helvetica, sans-serif;">" ></span>

in_from_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator" >

    <translate
        android:duration="500"
        android:fromXDelta="100%p"
        android:toXDelta="0%p" />

</set>

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

        android:duration="500"
        android:fromXDelta="0%p"
        android:toXDelta="-100%p" />

</set>
