Google Map API V2 Android 片段

Question

我正在做一个项目，我需要加入 Google 地图。我正在使用 API v2，但在显示地图时遇到了一些问题。

    package com.lan.me;

import com.google.android.gms.maps.GoogleMap;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class Geoloc extends Fragment {

    GoogleMap map;
    View view;

    public static Fragment newInstance() {
        Geoloc mFrgment = new Geoloc();
        return mFrgment;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.map, container, false);

        return view;
    }
}

这是我的 Geoloc.java，在我的 map.xml 中有这个：

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.MapFragment" />  

我在编译或启动我的应用程序时没有任何问题，但是当我点击我的按钮时，我的应用程序不想工作。当我双击 LogCat 时，错误似乎在那里：

view = inflater.inflate(R.layout.map, container, false);

但我真的不明白为什么。有人有想法吗？

问题来了……

Answer 1

在这种情况下，您必须：

1) 使用 Fragment 扩展您的类

2) 在您的片段 xml 中采用相对布局并将您的片段与 id map 一起放入其中

3) 在 Fragment 类中添加你的 Fragment xml

4) 使用以下代码在 onActivityCreated() 中获取地图 ID

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

5) 没有第五步..:) 就是这样
