修改状态栏字体的主题颜色

以下代码需要在 API >= 23 即 最低版本Android 6.0 (M) ，才可以生效

 

public static void setStatusBarTheme(final Activity activity, final boolean needDarkFont) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        // fetch the current flags
        final int lFlags = activity.getWindow().getDecorView().getSystemUiVisibility();

        // SYSTEM_UI_FLAG_LIGHT_STATUS_BAR requests the status bar to draw in a mode
        // that is compatible with light status bar backgrounds

        // For this to take effect, the window must request FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS
        // but not FLAG_TRANSLUCENT_STATUS
        activity.getWindow().getDecorView().setSystemUiVisibility(
                needDarkFont ?
                (lFlags | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR) :
                (lFlags & ~View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR));
    }
}

 

SYSTEM_UI_FLAG_LIGHT_STATUS_BAR 告诉系统，当前的UI色彩偏淡，需要深色的字体来匹配；即设置该标志时，状态栏的字体会使用黑色；取反之后，系统会设置状态栏的字体为白色。

 

注意，根据API文档说明，要想该flag生效，需要同时设置 FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS， 而且取消设置 FLAG_TRANSLUCENT_STATUS， 对应的代码为

Window window = activity.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
