Question

我刚刚学习Android，在运行Google Map代码时遇到了一些问题。我在堆栈溢出中尝试了很多解决方案：

Mainactivity.java：扩展FragmentActivity而不是Activity
activity_main.xml：将片段名称更改为“com.samplefragsapplication.SuggestionFrags”或“com.google.android.gms.maps.SupportMapFragment”

它仍然不起作用。

这是activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

这是Mainactivity.java

package com.example.asg2b;

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

这是Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.asg2b"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

    <permission
        android:name="com.example.asg2b.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" >
    </permission>

    <uses-permission android:name="com.example.asg2b.permission.MAPS_RECEIVE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.asg2b.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="Android Key" />
    </application>

</manifest>

这是我从LogCat获得的日志

将此信息放在应用程序代码

下的清单中

  <meta-data
            android:name="com.google.android.gms.version"
            android:value="4030500" />

编辑：

并用此代码替换您的activity_main.xml代码

<fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"
         />

在Google Map中输入类片段时出错
