帮我检查系统启用暗模式时的开关

Answer 1

在 google Android 文档中找到了这段代码：

Java：

int currentNightMode = configuration.uiMode & Configuration.UI_MODE_NIGHT_MASK;
switch (currentNightMode) {
    case Configuration.UI_MODE_NIGHT_NO:
        // Night mode is not active, we're using the light theme
        break;
    case Configuration.UI_MODE_NIGHT_YES:
        // Night mode is active, we're using dark theme
        break;
}

科特林：

val currentNightMode = configuration.uiMode and Configuration.UI_MODE_NIGHT_MASK
when (currentNightMode) {
    Configuration.UI_MODE_NIGHT_NO -> {} // Night mode is not active, we're using the light theme.
    Configuration.UI_MODE_NIGHT_YES -> {} // Night mode is active, we're using dark theme.
}
