我正在使用教程尝试谷歌地图,但它没有显示地图;只是灰色的瓷砖。请帮助我..我的项目因此而陷入困境。

这是我的代码

以下是我再次尝试的编辑代码。请查看代码和 logcat 文件。

请参见此处,只需使用清单文件中的密钥更改 api 密钥并按照以下步骤操作:并确保您的 google_play_services_lib 项目应仅存在于项目的工作空间中。

清单文件:

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />

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

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <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" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.geeklabs.map.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="replace with your API key"/>

    </application>

</manifest>

MainActivity.java:

    package com.geeklabs.map;

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

public class MainActivity extends Activity {

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

}

活动主.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"/>

得到这个后告诉我。

该地图无法正常工作,因为您的清单设置不正确。从 Android 文档中使用本教程,并确保您启用所需的确切权限。此外,您的 API 密钥位于错误的位置。它在您的清单中,而不是在片段中。

在某些设备上加载 Google 地图第 2 版时存在一些问题,您只需重新启动设备即可开始工作。
