【中文标题】谷歌地图如何与安卓系统协同工作【英文标题】:How google map works with android 【发布时间】:2015-07-14 08:04:34 【问题描述】:三个月后,我仍然无法在我的项目中使用可用的 Google 地图。
我尝试了很多教程,但总是出现同样的问题,我无法运行它,我不知道如何解决它。
这是我的 Manifest.xml

这是我的 MainActivity: 包 com.example.androidmaphmida;
import android.os.Bundle;
import android.widget.Toast;
import android.app.Activity;
import com.example.androidmaphmida.R;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
public class MainActivity extends Activity
// Google Map
GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
map = ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
//geolocalisation
map.setMyLocationEnabled(true);
@Override
protected void onResume()
super.onResume();

【问题讨论】:
【参考方案1】:你真的很接近,看起来你只是在<activity>
下的错误位置添加了<meta-data>
标签而不是<application>
尝试使用此代码代替您的清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.androidmaphmida"
android:versionCode="1"
android:versionName="1.0" >
<permission
android:name="com.example.androidmaphmida.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.androidmaphmida.permission.MAPS_RECEIVE" />
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="21" />
<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="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- Required OpenGL ES 2.0. for Maps V2 -->
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name">
<activity
android:name="com.example.androidmaphmida.MainActivity"
android:label="@string/app_name"
android:theme="@style/AppBaseTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- Goolge API Key -->
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyBg-SzhfkXjGUDK037BbmsG4Hv3yrY6c2M" />
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.androidmaphmida.MainActivity" />
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
</application>
【讨论】:
【参考方案2】:尝试以这种方式替换您的 Java 文件和布局文件:
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_
android:layout_
tools:context=".MainActivity" >
<TextView
android:layout_
android:layout_
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="@string/hello_world" />
<fragment
android:id="@+id/map"
android:layout_
android:layout_
class="com.google.android.gms.maps.SupportMapFragment"/>
</RelativeLayout>
MainActivity.java:
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
public class MainActivity extends FragmentActivity
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
