Question

我有FragmentActivity使用2种不同的布局取决于屏幕尺寸：

xLarge Landscape。布局有3个LinearLayouts，每个包含1个片段。
休息屏幕尺寸。布局有1 ViewPager，其中包含所有片段。

当屏幕方向在10英寸屏幕中发生变化时，应用程序崩溃。它在横向模式下使用屏幕尺寸1，在纵向模式下使用尺寸2。

代码：

public class RegistroAccionesPartidoActivity extends FragmentActivity {


private static ArrayAdapter<Fragment> mFragmentArray;
private ViewPager mMyPager;
private Fragment1 mFragment1;

private Fragment2 mFragment2;
private Fragment3 mFragment3;
private MyFragmentAdapter mFragmentsAdapter;
private FragmentManager mFragmentManager;
private FragmentTransaction mFragmentTrasaction;


@Override
public void onCreate(Bundle savedState) {
    super.onCreate(savedState); 
    setContentView(R.layout.my_layout); 


    LinearLayout layoutFragment1 = (LinearLayout)findViewById(R.id.fragment1);


    if(layoutFragment1 == null) {

        mFragmentManager = getSupportFragmentManager();

        mMyPager = (ViewPager) findViewById(R.id.my_pager);
        mFragmentArray = new ArrayAdapter<Fragment>(getApplicationContext(),android.R.layout.simple_list_item_1);
        mFragmentsAdapter = new Fragment2Adapter(mFragmentManager);


        if(savedState == null) { 

            mFragment2 = new Fragment2(true);
            mFragment3 = new Fragment3();
            mFragment1 = new Fragment1(mIdPartido, mIdEquipoLocal, mIdEquipoVisitante);
        } else {

            mFragment1 = (Fragment1) getSupportFragmentManager().getFragment(savedState, "fragment1");
            mFragment2 = (Fragment2) getSupportFragmentManager().
            getFragment(savedState,"fragment2");
            mFragment3 = (Fragment3) getSupportFragmentManager().
            getFragment(savedState, "fragment3");
        }


        mFragmentArray.add(mFragment1);
        mFragmentArray.add(mFragment2);
        mFragmentArray.add(mFragment3);

        mDatosPartidoPager.setAdapter(mFragmentsAdapter);

        mDatosPartidoPager.setCurrentItem(1);


       } else { // xLarge Version

        mFragmentManager = getSupportFragmentManager();
        mFragmentTrasaction = mFragmentManager.beginTransaction();


        if(savedState == null) {
            mFragment1 = new Fragment1();
            mFragment2 = new Fragment2();
            mFragment3 = new Fragment3();


        } else {
            mFragment1 = (Fragment1) getSupportFragmentManager().
                getFragment(savedState, "fragment1");

            mFragment2 = (Fragment2) getSupportFragmentManager().
                getFragment(savedState,"fragment2");
            mFragment3 = (Fragment3) getSupportFragmentManager().
                getFragment(savedState, "fragment3");
    }
    mFragmentTrasaction.add(R.id.fragment1, mFragment1);
    mFragmentTrasaction.add(R.id.fragment2, mFragment2);
    mFragmentTrasaction.add(R.id.fragment3, mFragment3);
    mFragmentTrasaction.commit();
    }

}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);

    getSupportFragmentManager().putFragment(outState, "fragment2" , 
        mFragment2);
    getSupportFragmentManager().putFragment(outState, "fragment3", 
        mFragment3);

    getSupportFragmentManager().putFragment(outState,"fragment1", 
        mFragment1);

    }
}

XLarge布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/fragment1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1">

</LinearLayout>


<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/fragment2"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1">

</LinearLayout>

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/fragment3"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1">

</LinearLayout>


</LinearLayout>

其余屏幕尺寸布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <android.support.v4.view.ViewPager
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/my_pager">

    </android.support.v4.view.ViewPager>

</LinearLayout>

根据屏幕更改的顺序，我有2次不同的崩溃：

从横向开始，错误消息为：

java.lang.IllegalArgumentException：找不到ID为0x的视图......对于Fragment2

当我开始使用肖像时，错误消息为：

java.lang.IllegalStateException：已添加片段：Fragment1

抱歉这个大问题。我只是想明确解释我的问题。

非常感谢。

编辑：在大型设备（如10''）中，横向模式使用xLarge布局，纵向模式使用其他布局。

Answer 1

对我来说（在XLarge布局内）嵌套的LinearLayout-Elements混合水平和垂直方向看起来很奇怪。如果你想以这种方式嵌套，请仔细看看。

问候，沃尔夫冈
