我有一個包含RecyclerView的片段（SearchResultsFragment）。搜索結果被加載到RecyclerView（這是一系列CardViews）。Android錯誤充氣視圖
當用戶選擇一個CardView，它們被帶到其中從所選擇的卡數據被加載的另一片段（EventDetailsFragment）。所有這些工作正常，我現在唯一的問題是，當用戶選擇手機上的後退按鈕，應用程序崩潰，給我一個錯誤，該XML文件不能被誇大。
我懷疑這可能是一個與我RecyclerView。
E/UncaughtException: android.view.InflateException: Binary XML file line #18: Binary XML file line #18: Error inflating class fragment
我也收到此錯誤：
Caused by: java.lang.IllegalArgumentException: Binary XML file line #18: Duplicate id 0x7f0f0159, tag null, or parent id 0x7f0f0158 with another fragment for com.google.android.gms.location.places.ui.PlaceAutocompleteFragment
這裏是我的SearchResultsFragment代碼：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View currentView = inflater.inflate(R.layout.fragment_start_search, container, false);
resolvingError = savedInstanceState != null && savedInstanceState.getBoolean(RESOLVING_ERROR, false);
initializeComponents(currentView);
buildGoogleApi();
handlePermissions();
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
getDeviceSuggestedLocations();
}
return currentView;
}
private void initializeComponents(final View currentView) {
searchResultsRecyclerView = (RecyclerView) currentView.findViewById(R.id.EventSearchResultsRecyclerView);
searchResultsRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
autoCompleteFragment = (PlaceAutocompleteFragment) getChildFragmentManager().findFragmentById(R.id.GoogleSearchFragment);
autoCompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
currentLocation = place.getName().toString();
selectedPlace = place;
processSearch();
}
@Override
public void onError(Status status) {
displayMessage("Error Getting Location", status.getStatusMessage());
}
});
}
這是一個失敗，按下後退按鈕時，膨脹的XML文件：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:orientation="vertical"
>
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id ="@+id/SearchLinearLayout"

</LinearLayout>
</android.support.v7.widget.CardView>

android:layout_height="wrap_content"

編輯：這是片段得到熱插撥活動（MainActivity） - 根據什麼選擇的是：
public class MainActivity extends AppCompatActivity implements View.OnClickListener{
private Toolbar mainActivityToolbar;
private TextView toolbarTextView;
private ImageView toolbarImage;
private FragmentManager mgr;
private NavigationView navigationView;
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle drawerToggle;
private SharedPreferences activityPreferences;
private SharedPreferences appSharedPreferences;
private SharedPreferences.Editor editor;
protected void onCreate(Bundle savedInstanceState) {
if (savedInstanceState == null) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initializeControls();
loadLandingScreenFragment();
} else {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initializeControls();
}
}
public void initializeControls()
{
mainActivityToolbar = (Toolbar) findViewById(R.id.MainActivityToolbar);
toolbarTextView = (TextView) findViewById(R.id.MainActivityTextView);
toolbarImage = (ImageView) findViewById(R.id.MainActivityImageView);
drawerLayout = (DrawerLayout) findViewById(R.id.menuDrawerLayout);
navigationView = (NavigationView) findViewById(R.id.mainActivityNavigationView);
setSupportActionBar(mainActivityToolbar);
getSupportActionBar().setTitle(null);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(true);
drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, mainActivityToolbar, R.string
.app_name, R
.string
.app_name);
drawerLayout.setDrawerListener(drawerToggle);
navigationView.inflateHeaderView(R.layout.navigation_menu_header);
navigationView.inflateMenu(R.menu.athlete_navigation_menu);
toolbarImage.setOnClickListener(this);
appSharedPreferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
activityPreferences = getSharedPreferences("iBaleka", MODE_PRIVATE);
editor = activityPreferences.edit();
NavigationMenuOnItemSelectedListener listener = new NavigationMenuOnItemSelectedListener
(this);
navigationView.setNavigationItemSelectedListener(listener);
toolbarImage.setImageResource(R.drawable.ibaleka_logo);
mgr = getFragmentManager();
mapComponents();
}
public void loadLandingScreenFragment()
{
AthleteLandingFragment landingFragment = new AthleteLandingFragment();
FragmentTransaction transaction = mgr.beginTransaction();
transaction.replace(R.id.MainActivityContentArea, landingFragment, "UserStats");
transaction.addToBackStack("UserStats");
transaction.commit();
}
private void mapComponents()
{
View headerView = navigationView.getHeaderView(0);
TextView athleteNameSurname = (TextView) headerView.findViewById(R.id.profileNameSurname);
TextView emailAddress = (TextView) headerView.findViewById(R.id.profileEmailAddress);
String nameSurname = appSharedPreferences.getString("Name", "") + " "+ appSharedPreferences.getString("Surname", "");

editor.commit();
super.onPause();
}

@Override

mgr.popBackStack();
} else {
super.onBackPressed();
}
}
問題是你如何加載片段;你看，你在另一個片段中有一個片段 - 你需要看看如何從父片段中膨脹一個子片段 – Eenvincible
你能顯示你的活動代碼（或任何組件持有片段）嗎？我懷疑你試圖添加一個片段兩次，一次是在活動的第一次開始，一次是在你回到活動時。如果以編程方式添加任何片段，則需要檢查片段管理器中是否存在片段。 –
您的活動的郵政編碼。看來，android：id =「@ + id/GoogleSearchFragment」被添加了兩次。一旦在xml中，另一次在代碼中。 – Rafal
