Question

我用Lg Q6。版本7.1.1。导航栏颜色不会随着下面的代码而改变。我尝试动态更改并使用主题，但没有任何变化。我不明白我在哪里做错了什么？

首先以编程方式尝试

WITH

然后尝试style.xml

Manifest.xml

alter session set nls_date_format = 'dd/mm/yyyy';

with
  test_data (sr_no, name, status, dt) as (
    select 121, 'HP'   , 'OK' , to_date('12/06/2018') from dual union all
    select 122, 'Dell' , 'OK' , to_date('15/06/2018') from dual union all
    select 123, 'MAC'  , 'NOK', to_date('30/07/2018') from dual union all
    select 124, 'Apple', 'NOK', to_date('03/09/2018') from dual union all
    select 125, 'MI'   , 'NOK', to_date('04/09/2018') from dual union all
    select 126, 'Oppo' , 'NOK', to_date('05/09/2018') from dual union all
    select 127, 'Vivo' , 'OK' , to_date('06/09/2018') from dual
  )
select case grouping_id(flag) when 0
                              then case flag when 'b' then 'Till 30th July'
                                             else          'After 30th July'
                                   end
                              else                         'Total'
       end                                      as category
     , count(status)                            as ct
     , count(case status when 'OK' then 0 end)  as ok
     , count(case status when 'NOK' then 0 end) as nok
from   ( select sr_no, name, status, dt, 
                case when dt <= date '2018-07-30' then 'b' end as flag
         from   test_data
       )
group by rollup(flag)
order by grouping_id(flag), flag
;

CATEGORY                CT         OK        NOK
--------------- ---------- ---------- ----------
Till 30th July           3          2          1
After 30th July          4          1          3
Total                    7          3          4

style.xml

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {                
   getWindow().setNavigationBarColor(getResources().getColor(R.color.your_awesome_color));
}

每次您要在整个应用程序中更改评论或项目的颜色时，最好在其中添加特殊样式并将其引入程序的原始样式。

例如：如果要更改底部导航栏的背景，则可以在style.xml v21中的行下添加：

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:navigationBarColor">@color/colorAccent</item>
    </style>

但是如果要更改工具栏的背景颜色，则应为其定义样式，例如：

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        .
        .
        .
        <item name="toolbarStyle">@style/MyStyle</item>
    </style>

<style name="MyStyle" parent="Theme.AppCompat.Light">
    <item name="android:background">#024dfc</item>
</style>

您可以使用这种方式为您的应用定义夜间和白天主题。希望您喜欢。
