我有一个视图寻呼机，我尝试在主片段中嵌套一个地图片段。为什么我不断收到“Error inflating class fragment”？

Question

从本周开始我就一直在研究这个特殊问题。我已经阅读了关于堆栈溢出的博客和建议的答案。我尝试了不同的解决方案，甚至使用了此处接受的一些答案，但我的应用程序仍然不断崩溃。我也尝试了 mapview，但它没有用。我需要一些帮助来解决这个问题。我以前实现过一张地图，我没有遇到任何问题，但那是在 activity 中。我在片段中实施时遇到问题，应用程序总是在 view = inflater.inflate(R.layout.fragment_serv__base_data, container, false); init();

崩溃

下面是我的清单文件：

这里是 xml:

下面是fragment.java:

public class Serv_BaseDataFragment extends Fragment {

    view = inflater.inflate(R.layout.fragment_serv__base_data, container, false);
    init();
    return view;

}


public void init(){

    googleMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

    sysaid = (EditText)view.findViewById(R.id.sysaidIdEditText);

    sign_client = (Button)view.findViewById(R.id.clientSignatureButton);
    sign_client.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(getActivity(), ClientSignatureActivity.class);
            startActivityForResult(intent, 1);
        }
    });

    sign_STL = (Button)view.findViewById(R.id.STLSignatureButton);
    sign_STL.setOnClickListener(new View.OnClickListener() {

            Intent intent = new Intent(getActivity(), STLSignatureActivity.class);
            startActivityForResult(intent, 1);
        }
    });

    location = (Button)view.findViewById(R.id.getLocationButton);
    location.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });


}

}

Answer 1

确保 <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="AIzaSyA5ULk7TurdcL5PqVOjJ1ZDf9wiZJIwgZc" /> 在 <application> 元素内。如果您决定使用地图视图，您可以关注。问题下的评论里还有其他很好的建议。

让我补充一点，当我测试 mapview 示例时 mContext = getActivity(); 对我不起作用，所以我将其注释掉了。此外，代码块中没有使用 mContext。

我有一个视图寻呼机，我尝试在主片段中嵌套一个地图片段。为什么我不断收到“Error inflating class fragment”？

I have a view pager and I try to nest a fragment for a map within the main fragment. Why do I keep getting " Error inflating class fragment"?
