Question

是否可以根据一天中的时间设置不同的启动屏幕。我曾尝试用相同的命名图像来创建values-night / styles.xml和values-notnight / styles.xml以及一个drawable-night和drawable-notnight，但是它不会根据电话的时间交替显示。

有人有没有在主活动中使用计时器而不具有启动屏幕的经验吗？

因此，仅在加载主要活动之前执行启动屏幕。

我缺少设置步骤吗？

values-notnight / styles.xml

document.getElementById("<%=RadButton1.ClientID%>").removeAttribute("disabled");

values-notnight / styles.xml

Answer 1

您必须做的三件事

首先：白天，文件夹名称为values，晚上，文件夹名称为values-night。可相应绘制drawable和drawable-night。

第二： 使用Theme.AppCompat.DayNight.DarkActionBar作为父主题。

第三：在布局中使用ViewFlipper

在您的代码中找到当前时间并检查预期时间：

  ViewFlipper vf = (ViewFlipper) findViewById( R.id.viewFlipper );
  if (mCurrentTime == //whatever time you want) {
        vf.showNext();
  }
