准备

screen_zoom_in

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator">
    <scale
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromXScale="2.0"
        android:fromYScale="2.0"
        android:pivotX="50%p"
        android:pivotY="50%p"
        android:toXScale="1.0"
        android:toYScale="1.0" />

    <alpha
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromAlpha="0"
        android:toAlpha="1.0" />
</set>

screen_zoom_out

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator">
    <scale
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromXScale="1.0"
        android:fromYScale="1.0"
        android:pivotX="50%p"
        android:pivotY="50%p"
        android:toXScale="2.0"
        android:toYScale="2.0" />

    <alpha
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromAlpha="1.0"
        android:toAlpha="0" />
</set>

使用

进

Intent intent = new Intent(MainActivity.this, WhiteBoardActivity.class);
startActivity(intent);
overridePendingTransition(R.anim.screen_zoom_in, R.anim.screen_zoom_out);

退

finish();
overridePendingTransition(R.anim.screen_zoom_in, R.anim.screen_zoom_out);

源码

/**
 * Call immediately after one of the flavors of {@link #startActivity(Intent)}
 * or {@link #finish} to specify an explicit transition animation to
 * perform next.
 *
 * <p>As of {@link android.os.Build.VERSION_CODES#JELLY_BEAN} an alternative
 * to using this with starting activities is to supply the desired animation
 * information through a {@link ActivityOptions} bundle to
 * {@link #startActivity(Intent, Bundle)} or a related function.  This allows
 * you to specify a custom animation even when starting an activity from
 * outside the context of the current top activity.
 *
 * @param enterAnim A resource ID of the animation resource to use for
 * the incoming activity.  Use 0 for no animation.
 * @param exitAnim A resource ID of the animation resource to use for
 * the outgoing activity.  Use 0 for no animation.
 */
public void overridePendingTransition(int enterAnim, int exitAnim) {
    try {
        ActivityManagerNative.getDefault().overridePendingTransition(
                mToken, getPackageName(), enterAnim, exitAnim);
    } catch (RemoteException e) {
    }
}

注意

• overridePendingTransition需startAtivity或finish后立即执行。
• 需动画否灵活控（无需传0）。
• 进、退动画全配效果更佳（视动画效果定，如上缩透动画）。
