Launcher3主菜单背景不透wallpaper

[DESCRIPTION]
Launcher3主菜单背景不透wallpaper
 
 
 
[SOLUTION]
AppsCustomizeTabHost控制的
在\packages\apps\Launcher3\src\com\android\launcher3\AppsCustomizeTabHost.java
    private void onTabChangedEnd(AppsCustomizePagedView.ContentType type) {
        int bgAlpha = (int) (255 * (getResources().getInteger(
            R.integer.config_appsCustomizeSpringLoadedBgAlpha) / 100f));
        setBackgroundColor(Color.argb(bgAlpha, 0, 0, 0)); //bgAlpha 是透明度，如果不透wallpaper，需要透明度为ff，即255
        mAppsCustomizePane.setContentType(type);
    }
按照上面代码逻辑，要不透明，需要修改config_appsCustomizeSpringLoadedBgAlpha为100
