二进制 XML 文件第 26 行：与另一个片段重复 id、标记 null 或父 id

Question

我正在尝试将一个片段插入另一个片段，并且我已经成功地做到了这一点，直到我第一次吃午饭主片段，但当我尝试重新加载片段时，应用程序崩溃了，并且我有这个错误：

Caused by: java.lang.IllegalArgumentException: Binary XML file line #26:
Duplicate id 0x7f0e00e2, tag null, or parent id 0xffffffff with another
fragment for com.google.android.gms.location.places.ui.PlaceAutocompleteFragment

这是我的片段

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

View  rootView = inflater.inflate(R.layout.source_destination,container, false);
PlaceAutocompleteFragment sourcr_autocompleteFragment = (PlaceAutocompleteFragment)
          getActivity().getFragmentManager()
.findFragmentById(R.id.sourcr_autocomplete_fragment);
return rootView;

// List item

}

这是我的 XML

 <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:padding="10dp"
        android:background="@color/colorPrimary"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
       <android.support.v7.widget.CardView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="@dimen/margin_medium"
            android:layout_marginBottom="@dimen/margin_medium">

            <fragment
                android:id="@+id/sourcr_autocomplete_fragment"    
                android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"           
              android:layout_width="match_parent"
              android:layout_height="wrap_content" />

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

Answer 1

我刚刚遇到了同样的问题，可以通过删除 onDismiss 回调中的片段来解决。

@Override
public void onDismiss(DialogInterface dialog) {
    super.onDismiss(dialog);

    if (getActivity() != null) {
        FragmentManager fragmentManager = getActivity().getFragmentManager();
        Fragment fragment = fragmentManager.findFragmentById(R.id.sourcr_autocomplete_fragment);
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.remove(fragment);
        fragmentTransaction.commit();
    }
}

Answer 2

覆盖片段中的 onDestroyView 方法

public void onDestroyView() {
    super.onDestroyView();
    FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
    Fragment fragment = fragmentManager.findFragmentById(R.id.sourcr_autocomplete_fragment);
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.remove(fragment);
    fragmentTransaction.commit();
}

科特林：

override fun onDestroyView() {
    super.onDestroyView()
    activity?.supportFragmentManager?.also { fragmentManager ->
        fragmentManager.findFragmentById(R.id.aboutFragment)?.also { fragment ->
            fragmentManager.beginTransaction().remove(fragment).commit()
        }
    }
}
