Android Wear DayNight主题程序兼容性

Question

我试图使用程序兼容性DayNight主题在我的Android Wear应用，但它不工作，我的活动需要的环境模式，所以我延长WearableActivity这样的：

public class BaseActivity extends WearableActivity { 

    @Override 
    protected void onCreate(@Nullable Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setAmbientEnabled(); 
     .... 
    } 

} 

对于我的主题我碰到这样的：

<style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar"> 
     <item name="android:windowNoTitle">true</item> 
     <item name="android:windowBackground">@color/colorBackground</item> 
     <item name="colorPrimary">@color/colorPrimary</item> 
     <item name="colorPrimaryDark">@color/colorPrimaryDark</item> 
     <item name="colorAccent">@color/colorAccent</item> 
     <item name="android:textColorPrimary">@color/textColorPrimary</item> 
    </style> 

但没有什么工作，主题不会改变在所有...我用同样的主题在我的手机应用程序和它的作品，唯一的区别是，我的活动延伸AppCompatActivity。

有没有办法使它适用于Android Wear应用程序？

我管理，使之成为我的使用情况下的工作，加入这个我WearableActivity（从AppCompatActivity复制/粘贴）（强迫白天或晚上）：

public class BaseActivity extends WearableActivity implements AppCompatCallback { 
    private AppCompatDelegate delegate; 
    private int themeId = 0; 

    @Override 
    protected void onCreate(@Nullable Bundle savedInstanceState) { 

     final AppCompatDelegate delegate = getDelegate(); 
     delegate.installViewFactory(); 
     delegate.onCreate(savedInstanceState); 
     if (delegate.applyDayNight() && themeId != 0) { 
      // If DayNight has been applied, we need to re-apply the theme for 
      // the changes to take effect. On API 23+, we should bypass 
      // setTheme(), which will no-op if the theme ID is identical to the 
      // current theme ID. 
      if (Build.VERSION.SDK_INT >= 23) { 
       onApplyThemeResource(getTheme(), themeId, false); 
      } else { 
       setTheme(themeId); 
      } 
     } 
     super.onCreate(savedInstanceState); 
    } 

    @Override 
    public void setTheme(@StyleRes final int resid) { 
     super.setTheme(resid); 
     // Keep hold of the theme id so that we can re-set it later if needed 
     themeId = resid; 
    } 

    @Override 
    protected void onSaveInstanceState(Bundle outState) { 
     super.onSaveInstanceState(outState); 
     getDelegate().onSaveInstanceState(outState); 
    } 

    /** 
    * @return The {@link AppCompatDelegate} being used by this Activity. 
    */ 
    @NonNull 
    public AppCompatDelegate getDelegate() { 
     if (delegate == null) { 
      delegate = AppCompatDelegate.create(this, this); 
     } 
     return delegate; 
    } 

    @Override 
    public void onSupportActionModeStarted(ActionMode mode) { 

    } 

    @Override 
    public void onSupportActionModeFinished(ActionMode mode) { 

    } 

    @Nullable 
    @Override 
    public ActionMode onWindowStartingSupportActionMode(ActionMode.Callback callback) { 
     return null; 
    } 
} 

现在我可以用AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES/NO);
