Question

我的所有活动都扩展了MainActivity并共享了activity_main布局。在我的一个活动中，我正在使用slidinguppanel库，因此布局不同。当我在添加布局视图后尝试附加片段时，出现错误：

10-16 15:25:14.155 32590-32590/com.myproject.myapp E/AndroidRuntime: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.myproject.myapp/com.myproject.myapp.search.SearchActivity}: java.lang.IllegalArgumentException: No view found for id 0x7f0d00ea (com.myproject.myapp/searchContainer) for fragment SearchFragment{2e02f51a #0 id=0x7f0d00ea SearchFragment}

我做错了什么？

MainActivity.java oncreate：

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    if (getSupportActionBar() != null) {
        getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_action_hamburger_icon);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }

    mMainContainer = (FrameLayout) findViewById(R.id.mainContainer);
    mCoordinatorLayout = (CoordinatorLayout) findViewById(R.id.coordinatorLayout);
    mAppBarLayout = (AppBarLayout) findViewById(R.id.appBarLayout);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    mUserImageView = (RoundedImageView) navigationView.findViewById(R.id.userImageView);
    mRealNameView = (TextView) navigationView.findViewById(R.id.realNameText);
    mUserNameView = (TextView) navigationView.findViewById(R.id.userNameText);

    showUserInfo(mUser != null);
}

activity_main.xml中：

    <?xml version="1.0" encoding="utf-8"?>

    Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);

    mDrawerLayout.addView(view);

    toolbar.setTitleTextColor(Color.WHITE);
    setSupportActionBar(toolbar);
    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            toggleDrawer();
        }
    });

    SearchFragment searchFragment = (SearchFragment) getSupportFragmentManager().findFragmentByTag("SearchFragment");
    if (searchFragment == null) {
        FrameLayout searchContainer = (FrameLayout) view.findViewById(R.id.searchContainer);
        searchContainer.setId(R.id.searchContainer);
        getSupportFragmentManager()
                .beginTransaction()
                .add(R.id.searchContainer, SearchFragment.newInstance(), "SearchFragment") // here's the problem
                .commit();
    }

    SearchResultPagerAdapter pagerAdapter = new SearchResultPagerAdapter(getSupportFragmentManager());
    viewPager.setAdapter(pagerAdapter);
    TabLayout tabStrip = (TabLayout) view.findViewById(R.id.tl_searchResultTabs);
    tabStrip.setupWithViewPager(viewPager);
    viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {

        }

        }

        @Override

            if (state == ViewPager.SCROLL_STATE_SETTLING) {
                switch (viewPager.getCurrentItem()) {
                    case 1:
                        if (foursquareResultsObject != null) {
                            EventBus.getDefault().post(new PopulateSearchMapEvent(foursquareResultsObject));
                        }
                        break;

                    default: //case 0
                        if (foursquareResultsObject != null) {
                            EventBus.getDefault().post(new PopulateSearchListEvent(foursquareResultsObject));
                        }
                        break;

Answer 1

在SearchActivity中，您使用的是activity_main布局，而不是您拥有片段容器的search_app_bar_layout。

从此更改

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

到此：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.search_appbar_layout);

替换片段：IllegalArgumentException：找不到id的视图
