Activity之间切换的动画

void android.app.Activity.overridePendingTransition(int
enterAnim, int exitAnim)

public
void overridePendingTransition
(int enterAnim, int exitAnim)

Since: API
Level 5

Call immediately after one of the flavors of

startActivity(Intent)

or

finish()

to specify an explicit transition animation to perform next.

Parameters

enterAnim	A resource ID of the animation resource to use for the incoming activity. Use 0 for no animation.
exitAnim	A resource ID of the animation resource to use for the outgoing activity. Use 0 for no animation.

-----------------------------------------------------------------------------------------------
在代码中，我们只需要实现如下：

Intent intent = new Intent();
intent.setClass(TestActivity.this,
MyActivity.class);
startActivity(intent);

overridePendingTransition(R.anim.in_from_right,
R.anim.out_to_left);//这里的enterAnim和exitAnim可以自己发挥

这两个resource
file是放在res目录下的anim目录中。下面写两个简单的animation：
-------------------------------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:fromXDelta="100%p"
android:toXDelta="0%p"
   
    android:duration="500"
/>
</set>

------------------------------------out_to_left.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:fromXDelta="0%p"
android:toXDelta="-100%p"
   
    android:duration="500"
/>
</set>
