关闭该动画

----------
1、在WindowManagerService中定义 过渡动画缩放 默认的级别

private float mTransitionAnimationScaleSetting = 1.0f;

2、在WindowManagerService的构造方法中，重新赋值

mTransitionAnimationScaleSetting = Settings.Global.getFloat(resolver,
                Settings.Global.TRANSITION_ANIMATION_SCALE,
                context.getResources().getFloat(
                        R.dimen.config_appTransitionAnimationDurationScaleDefault));

3、在DatabaseHelper中加载默认值

        loadFractionSetting(stmt, Settings.System.TRANSITION_ANIMATION_SCALE,
                R.fraction.def_window_transition_scale, 1);

4、修改R.fraction.def_window_transition_scale的值即可

-    <fraction name="def_window_transition_scale">100%</fraction>
+    <fraction name="def_window_transition_scale">0%</fraction>

5、修改AnimatorDurationScalePreferenceController文件，在Settings源码中

-    static final float DEFAULT_VALUE = 1;
+    static final float DEFAULT_VALUE = 0;

0为关闭
