Question

我对Android编程很新，我创建了一个包含许多片段的应用程序。我已按照Google的说明设置了如何设置Google Ad Mobs。当你点击一个特定的片段时，我第一次使用它。但是，如果我返回到该片段，应用程序崩溃并且没有点击Ad Fragment类......

我的Java课程：

public class ContactsListFragment extends BaseFragment {
ArrayList<Contact> allContacts = new ArrayList<Contact>();

...


public static class PlaceholderFragment extends Fragment {

    public PlaceholderFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_ad, container, false);
        return rootView;
    }
}

public static class AdFragment extends Fragment {

    private AdView mAdView;

    public AdFragment() {
    }

    @Override
    public void onActivityCreated(Bundle bundle) {
        super.onActivityCreated(bundle);

        // Gets the ad view defined in layout/ad_fragment.xml with ad unit ID set in
        // values/strings.xml.
        mAdView = (AdView) getView().findViewById(R.id.adView);

        // Create an ad request. Check logcat output for the hashed device ID to
        // get test ads on a physical device. e.g.
        // "Use AdRequest.Builder.addTestDevice("ABCDEF012345") to get test ads on this device."
        AdRequest adRequest = new AdRequest.Builder()
                .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                .build();

        // Start loading the ad in the background.
        mAdView.loadAd(adRequest);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_ad, container, false);
    }

    /** Called when leaving the activity */
    @Override
    public void onPause() {
        if (mAdView != null) {
            mAdView.pause();
        }
        super.onPause();
    }

    /** Called when returning to the activity */
    @Override
    public void onResume() {
        super.onResume();
        if (mAdView != null) {
            mAdView.resume();
        }
    }

    /** Called before the activity is destroyed */
    @Override
    public void onDestroy() {
        if (mAdView != null) {
            mAdView.destroy();
        }
        super.onDestroy();
    }

}

我的这个类的xml文件：

<fragment
    android:id="@+id/adFragment"
    android:name="com.oozzat.app.ContactsListFragment$AdFragment"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true" />

我的Logcat看起来像这样：

12-19 09:35:13.474: E/AndroidRuntime(22409): FATAL EXCEPTION: main 12-19 09:35:13.474: E/AndroidRuntime(22409): android.view.InflateException: Binary XML file line #80: Error inflating class fragment 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:719) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.view.LayoutInflater.rInflate(LayoutInflater.java:761) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.view.LayoutInflater.inflate(LayoutInflater.java:498) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.view.LayoutInflater.inflate(LayoutInflater.java:398) 12-19 09:35:13.474: E/AndroidRuntime(22409): at com.oozzat.app.ContactsListFragment.onCreateView(ContactsListFragment.java:52) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.support.v4.app.Fragment.performCreateView(Fragment.java:1500) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:938) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1115) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.support.v4.app.BackStackRecord.run(BackStackRecord.java:682) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1478) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.support.v4.app.FragmentManagerImpl$1.run(FragmentManager.java:446) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.os.Handler.handleCallback(Handler.java:730) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.os.Handler.dispatchMessage(Handler.java:92) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.os.Looper.loop(Looper.java:137) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.app.ActivityThread.main(ActivityThread.java:5419) 12-19 09:35:13.474: E/AndroidRuntime(22409): at java.lang.reflect.Method.invokeNative(Native Method) 12-19 09:35:13.474: E/AndroidRuntime(22409): at java.lang.reflect.Method.invoke(Method.java:525) 12-19 09:35:13.474: E/AndroidRuntime(22409): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1209) 12-19 09:35:13.474: E/AndroidRuntime(22409): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1025) 12-19 09:35:13.474: E/AndroidRuntime(22409): at dalvik.system.NativeStart.main(Native Method) 12-19 09:35:13.474: E/AndroidRuntime(22409): Caused by: java.lang.IllegalArgumentException: Binary XML file line #80: Duplicate id 0xffffffff, tag adFragmentPlaceholder, or parent id 0xffffffff with another fragment for com.oozzat.app.ContactsListFragment$PlaceholderFragment 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.app.Activity.onCreateView(Activity.java:4971) 12-19 09:35:13.474: E/AndroidRuntime(22409): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:695)

Answer 1

问题是

12-19 09:35:13.474: E/AndroidRuntime(22409): Caused by: java.lang.IllegalArgumentException: Binary XML file line #80: Duplicate id 0xffffffff, tag adFragmentPlaceholder, or parent id 0xffffffff with another fragment for com.oozzat.app.ContactsListFragment$PlaceholderFragment

基本上，您在同一View层次结构中多次使用相同的资源ID。

查看您正在加载的Activity和Fragments的布局XML。寻找重复的身份。

返回Fragment Android时，Admob崩溃了
