当我手动或从Android Market安装APK时,没有收到任何内容.为什么?
我有多个drawables,并希望将它组合成一个drawable(例如,4个方块,以创建一个大的正方形,如Windows徽标:)).我怎样才能做到这一点?

什么实际的发射器是开源的?我需要2.3+的启动器,但不需要启动器或ADW,因为它们已经不受支持.库存ICS +发射器不适用于2.3.

因此,这意味着CSS正确地从服务器加载.但它不起作用!如果我将此CSS作为文本直接包含在基本模板中,它可以正常工作.静态文件配置正常.
例如,我有2个模型:Model1和Model2.Model1有字段ForeignKey(Model2).Model2有方法,它返回Model1的所有实例,它将Model2的这个实例作为ForeignKey.
但它不起作用,因为Model2是在Model1之后定义的,它对Model2一无所知.如何解决这个问题呢?
