android - android.view.InflateException：二进制 XML 文件行：膨胀类片段时出错

Question

我正在尝试制作一个包含带有 3 个选项卡的 ActionBar 的应用程序：“地图”、“目的地”和“关于我们”。基本上，我使用 ViewPager 作为主要布局，对于单个寻呼机视图，我使用 Fragments。

activity_main.xml

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>

MainActivity.java

public class MainActivity extends FragmentActivity implements ActionBar.TabListener {   
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Maps", "Destinations", "About us" };

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

    // Initialization
    //tabs = getResources().getStringArray(R.array.tabs_titles);
    viewPager = (ViewPager) findViewById(R.id.pager);
    actionBar = getActionBar();
    mAdapter = new TabsPagerAdapter(getSupportFragmentManager());

    viewPager.setAdapter(mAdapter);
    //actionBar.setHomeButtonEnabled(false);
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);        

    // Adding Tabs
    for (String tab_name : tabs) {
        actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this));
    }

    /**
     * on swiping the viewpager make respective tab selected
     * */
    viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

        @Override
        public void onPageSelected(int position) {
            // on changing the page
            // make respected tab selected
            actionBar.setSelectedNavigationItem(position);
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {
        }

        @Override
        public void onPageScrollStateChanged(int arg0) {
        }
    });
}

/***************************************************************************************
 * 
 */
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

/***************************************************************************************
 * 
 */
@Override
public void onTabReselected(Tab tab, android.app.FragmentTransaction arg1) {


}

/***************************************************************************************
 * 
 */
@Override
public void onTabSelected(Tab tab, android.app.FragmentTransaction arg1) {
    // on tab selected
    // show respected fragment view
    viewPager.setCurrentItem(tab.getPosition());

}

/***************************************************************************************
 * 
 */
@Override
public void onTabUnselected(Tab tab, android.app.FragmentTransaction arg1) {
    // TODO Auto-generated method stub

}

}

我正在创建一个 FragmentPagerAdapter 类来为选项卡片段提供视图。

public class TabsPagerAdapter extends FragmentPagerAdapter {

public TabsPagerAdapter(FragmentManager fm) {
    super(fm);
}

@Override
public Fragment getItem(int index) {
    switch (index) {
    case 0:
        // Map fragment activity
        return new MapFragment();
    case 1:
        // Destinations fragment activity
        return new DestinationsFragment();
    case 2:
        // About Us fragment activity
        return new AboutUsFragment();
    }

    return null;
}

@Override
public int getCount() {
    // get item count - equal to number of tabs
    return 3;
}

}

每个项目都有一个带有其活动类的布局文件。

地图

fragment_map 布局

<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" >

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

</LinearLayout>

MapFragment 类

public class MapFragment extends Fragment {
GoogleMap mapa;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {    

try{
    if(mapa == null){
        mapa = ((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map)).getMap(); 
    }             
    View rootView = inflater.inflate(R.layout.fragment_map, container, false);          
    return rootView;
}catch(Exception e){
    View rootView = inflater.inflate(R.layout.fragment_map, container, false);

    e.printStackTrace();
    return rootView;
}

} }

目的地（现在只是一个带有文本视图的相对布局）

布局

        <?xml version="1.0" encoding="utf-8"?>
        <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:background="#ff8400" >

            <TextView 
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:text="Destinations Screen"
                android:textSize="20sp"
                android:layout_centerInParent="true"/>
        </RelativeLayout>

班级

public class DestinationsFragment extends Fragment {

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


        Log.d("", "CESAR");
        View rootView = inflater.inflate(R.layout.fragment_destinations, container, false);

        return rootView;
    }
}

关于我们（现在只是一个带有文本视图的相对布局）

布局

        <?xml version="1.0" encoding="utf-8"?>
        <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:background="#17df0d">

        <TextView android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="Diseñar la pantalla de About Us"
            android:textSize="20sp"
            android:layout_centerInParent="true"/>

        </RelativeLayout>

班级

        public class AboutUsFragment extends Fragment {

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

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

        return rootView;
     }
     }

问题是，当我从“关于我们”选项卡更改为任何其他选项卡时，应用程序停止工作并崩溃。但是，当我从选项卡“目的地”更改为“地图”选项卡并向后更改时，这不会发生。当我添加 MapFragment 时出现此错误，在此之前，地图布局只是带有文本视图的 RelativeLayout，并且运行良好。地图有效。

我仍在努力实施该解决方案，但它似乎是可行的。
