添加凌空依赖并按同步后。我取消了同步依赖项，之后当我重新打开项目时，我陷入了构建项目的困境。我还单击了清理项目和无效缓存和重新启动按钮。但它无法改变。我该如何解决？

我在我的 Android 项目中使用了灯光/夜间模式，并使用片段中的开关来更改模式。好吧，当我重新加载应用程序时它会改变。但我想更改模式而不重新加载应用程序。我怎样才能做到这一点？？？

• 我想在改变模式时保留当前片段。

  aSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
      @Override
      public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
          if(b){
              AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
              aSwitch.setChecked(true);
              sh = getActivity().getSharedPreferences("darklight",Context.MODE_PRIVATE).edit();
              sh.putBoolean("is",true);
              sh.commit();
          }else{
              AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);
              sh = getActivity().getSharedPreferences("darklight",Context.MODE_PRIVATE).edit();
              sh.putBoolean("is",false);
              sh.commit();
          }
      }
  });

我将Nextjs13v13.4.4 与Nodejsv18.16.0 一起使用，有时当我运行页面时，我收到此错误Error: fetch failed，当我记录错误时，会看到此错误

Sliders TypeError: fetch failed

}

这是我调用端点的方法

import errorMessage from "../errorMessage.json";
import { MainSliderType } from "@/app/types/response/slider";
const serverUrl = process.env.SERVERURL;

export const mainSliderFetcher = async (): Promise<MainSliderType[]> => {
  try {

当我在android studio底部导航栏中选择一个项目时，所选的背景项目等于values-> colors.xml中的primarycolor。现在我要更改与原色不同的颜色 我该如何更改？

    private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
            = new BottomNavigationView.OnNavigationItemSelectedListener() {
        Fragment fragment;
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {
            switch (item.getItemId()) {
                case R.id.navigation_home:
                    fragment = new HomeFragment();
                    loadFragment(fragment);
                    return true;
                case R.id.navigation_addpost:
                    fragment = new AddFragment();
                    loadFragment(fragment);
                    return true;
                case R.id.navigation_notifications:
//                    mTextMessage.setText(R.string.title_notifications);
                    return true;
                case R.id.navigation_profile:
                    fragment = new ProfileFragment();
                    loadFragment(fragment);
                    return true;
            }
            return false;
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
        loadFragment(new HomeFragment());
        BottomNavigationView navigation = (BottomNavigationView) findViewById(R.id.navigation);
        navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
        navigation.setItemTextColor(ColorStateList.valueOf(Color.RED));
