求教，android程序，夜间模式设置打开activity没效果

Question

• 1.侧滑界面中打开如下界面： Intent intent=new Intent(this, SettingActivity.class); startActivity(intent);

• 2.在SettingActivity中：
  protected void onCreate(Bundle savedInstanceState)
  {

  //TODO
  SharedPreferences sp = getPreferences(Context.MODE_PRIVATE);
  boolean isNight = sp.getBoolean("isNight", false);
  if (isNight)
  {
      setTheme(R.style.night);
  } else
  {
      setTheme(R.style.light);
  }
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_setting);
  

  *3.清单中：
  android:name="com.xinbo.app.BaseApp"
  android:allowBackup="true"
  android:icon="@drawable/ic_launcher"
  android:label="@string/app_name"
  android:theme="@style/light" >

• 4.style中：

 <style name="light" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="actionbar_bg">@color/actionbar_bg</item>
        <item name="left_head">@drawable/left_head_1</item>
        <item name="left_list">@color/white</item>
        <item name="card_bg">@color/white</item>
        <item name="textcoler">@color/background_floating_material_dark</item>
        <item name="set_list_bg_coler">@color/white</item>
        <item name="set_bg_coler">@color/material_grey_100</item>
    </style>

    <style name="night" parent="Theme.AppCompat.NoActionBar">
        <item name="actionbar_bg">@color/actionbar_bg_night</item>
        <item name="left_head">@drawable/left_head_2</item>
        <item name="left_list">@color/background_floating_material_dark</item>
        <item name="card_bg">@color/background_floating_material_dark</item>
        <item name="textcoler">@color/white</item>
        <item name="set_list_bg_coler">@color/black</item>
        <item name="set_bg_coler">@color/background_floating_material_dark</item>
    </style>

    求教，是哪里出问题了吗？怎么切换日夜间模式没效果

我试了一下，你的这个写法是对的，应该是是你的theme自定义有问题。建议排查theme
