Question

我正在尝试在平板电脑视图中制作2片段屏幕，但在旋转设备后它会崩溃。这是layout-sw600dp/

<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:baselineAligned="false"
    android:divider="?android:attr/dividerHorizontal"
    android:id="@+id/main_activity"
    android:orientation="horizontal"
    tools:context="com.morxander.popularmovies.MainActivity">


    <fragment
        android:id="@+id/fragment_main"
        android:name="com.morxander.popularmovies.MainActivity$PlaceholderFragment"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="4"
        tools:layout="@layout/fragment_main" />

    <FrameLayout
        android:id="@+id/movie_detail_container"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="3" />

</LinearLayout>

这是代码的相关部分：

    private static boolean mTwoPane;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if (findViewById(R.id.movie_detail_container) != null) {
        mTwoPane = true;
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                .replace(R.id.fragment_main, new PlaceholderFragment())
                .commit();
        }else{
            mTwoPane = false;
        }
    }

}
.....
.....
.....
public static class PlaceholderFragment extends Fragment {

    public PlaceholderFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        View rootView = inflater.inflate(R.layout.fragment_main, container, false);
        setHasOptionsMenu(true);
        // Method to set the views controls
        initComponents(rootView);
        return rootView;

当我旋转设备时，应用程序崩溃并给我以下错误：

    }

我尝试了很多解决方案，但没有任何对我有用。

Answer 1

尝试检查语句

中传递的布局

View rootView = inflater.inflate(R.layout.fragment_main, container, false);

片段在旋转设备后没有创建视图
