问题描述

我发现了类似主题的计算器，但它并没有帮助我。 我显示谷歌地图使用片段崩溃后获得另一个片段回来。 换句话说，谷歌地图上显示了仅一次和崩溃。 下面是C $ CS的$。

 公共类MapTabMainFragment扩展BaseFragment {

解决方案

您已经不能嵌套在XML片段。你应该这样做在code。 最好的方法是创建一个的FrameLayout，并与您的片段在运行时进行更换。

假设XML是如下：

 ＆LT; RelativeLayout的的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
的xmlns：广告=htt​​p://schemas.android.com/apk/res-auto
的xmlns：工具=htt​​p://schemas.android.com/tool​​s
机器人：ID =@ + ID / inquiryLayout
机器人：layout_width =match_parent
机器人：layout_height =match_parent
工具：上下文=InquiryFragment。＆GT;

＆LT;的FrameLayout
    机器人：ID =@ + ID / contentFrame
    机器人：layout_width =FILL_PARENT
    机器人：layout_height =FILL_PARENT
    机器人：layout_alignParentBottom =真
    机器人：layout_alignParentLeft =真正的＆GT;

＆LT; /的FrameLayout＆GT;
 ＆LT; / RelativeLayout的＆GT;
 

现在的code是简单的：

 公共类InquiryFragment扩展片段{

    公共查看onCreateView（LayoutInflater充气，容器的ViewGroup，捆绑savedInstanceState）{
        //充气的布局该片段
        视图V = inflater.inflate（R.layout.inquiry_fragment，集装箱，假）;

        Plan1Fragment FRAG =新Plan1Fragment（）;
        getChildFragmentManager（）的BeginTransaction（）
            .replace（R.id.contentFrame，FRAG）.commit（）;

        返回伏;
    }

}
 

这就是它。

I found similar topics in stackoverflow but it didn't help for me. I am showing google map using fragment and it crashes after get another fragment and come back. In other words, google map shows only once and crashes. Here are the codes.

public class MapTabMainFragment extends BaseFragment {
    private AdView adView;

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

        View view = null;
        try {
            view = inflater.inflate(R.layout.fragment_map_main, container,
                    false);
        } catch (Exception e) {
            e.printStackTrace();
        }

        initComponents(view);
        initValues();
        initListeners();

        return view;
    }

    public void initComponents(View view) {
        adView = (AdView) view.findViewById(R.id.adView1);
    }

    public void initValues() {
        AdRequest re = new AdRequest();
        adView.loadAd(re);
    }

    public void initListeners() {

    }
}

 public class BaseFragment extends Fragment {

    public BottomTabActivity mActivity;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mActivity = (BottomTabActivity) this.getActivity();
    }

    public boolean onBackPressed() {
        return false;
    }

    public void onActivityResult(int requestCode, int resultCode, Intent data) {

    }
}

when I try to catch the exception, it is

android.view.InflateException: Binary XML file line #20: Error inflating class fragment.

        </com.google.ads.AdView>
    </RelativeLayout>

</LinearLayout>

解决方案

You cannot have nested fragments in XML. You should do it in code. The best way is to create a FrameLayout, and replace it with your fragment at run-time.

Suppose the XML is as follows:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/inquiryLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".InquiryFragment" >

<FrameLayout
    android:id="@+id/contentFrame"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true" >

</FrameLayout>
 </RelativeLayout>

Now the code is simple:

public class InquiryFragment extends Fragment {

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View v = inflater.inflate(R.layout.inquiry_fragment, container, false);

        Plan1Fragment frag = new Plan1Fragment();
        getChildFragmentManager().beginTransaction()
            .replace(R.id.contentFrame, frag).commit();

        return v;
    }

}

And that's it.
