Question

我正在处理一个项目，我需要包含Google Map。我使用的是API v2，我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中我有这个：

<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" />

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，我的应用程序无法正常工作。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？

这是问题......

Answer 1

在这种情况下，您必须：

1）用片段扩展你的课程

2）在你的片段xml中采取相对布局并将你的片段放入id地图

3）在Fragment类中添加你的Fragment xml

4）使用下面的代码

在onActivityCreated（）中获取map id

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

5）没有第五步...... :) 多数民众赞成
