專案需要從系統級別將Activity過渡動畫全部關閉，在SettingsProvider中將TRANSITION_ANIMATION_SCALE設為0。

frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java

loadFractionSetting(stmt, Settings.System.TRANSITION_ANIMATION_SCALE,
                 R.fraction.def_window_transition_scale, 0);

float mTransitionAnimationScaleSetting = 0.0f;
 

frameworks/base/services/core/java/com/android/server/wm/WindowManagerService.java

    float mWindowAnimationScaleSetting = 1.0f;
    float mTransitionAnimationScaleSetting = 1.0f;
    float mAnimatorDurationScaleSetting = 1.0f;

1.Window:作用於非Activity視窗。

2.Activity:過渡效果。

3.View:屬性動畫，漣漪效果等。

依次是開發者選項中以下幾項：

視窗動畫縮放

過渡動畫縮放

動畫程式時長縮放

WindowManagerService對應的程式碼：

    @Override
    public void setAnimationScale(int which, float scale) {
        if (!checkCallingPermission(android.Manifest.permission.SET_ANIMATION_SCALE,
                "setAnimationScale()")) {
            throw new SecurityException("Requires SET_ANIMATION_SCALE permission");
        }

        scale = fixScale(scale);
        switch (which) {
            case 0: mWindowAnimationScaleSetting = scale; break;
            case 1: mTransitionAnimationScaleSetting = scale; break;
            case 2: mAnimatorDurationScaleSetting = scale; break;
        }

        // Persist setting
        mH.sendEmptyMessage(H.PERSIST_ANIMATION_SCALE);
    }

    @Override
    public void setAnimationScales(float[] scales) {
        if (!checkCallingPermission(android.Manifest.permission.SET_ANIMATION_SCALE,
                "setAnimationScale()")) {
            throw new SecurityException("Requires SET_ANIMATION_SCALE permission");
        }

        if (scales != null) {
            if (scales.length >= 1) {
                mWindowAnimationScaleSetting = fixScale(scales[0]);
            }
            if (scales.length >= 2) {
                mTransitionAnimationScaleSetting = fixScale(scales[1]);
            }
            if (scales.length >= 3) {
                mAnimatorDurationScaleSetting = fixScale(scales[2]);
                dispatchNewAnimatorScaleLocked(null);
            }
        }

        // Persist setting
        mH.sendEmptyMessage(H.PERSIST_ANIMATION_SCALE);
    }

 
 

    @Override
    public float getAnimationScale(int which) {
        switch (which) {
            case 0: return mWindowAnimationScaleSetting;
            case 1: return mTransitionAnimationScaleSetting;
            case 2: return mAnimatorDurationScaleSetting;
        }
        return 0;
    }

    @Override
    public float[] getAnimationScales() {
        return new float[] { mWindowAnimationScaleSetting, mTransitionAnimationScaleSetting,
                mAnimatorDurationScaleSetting };
    }
