问题：

Android谷歌地图：错误inflating类片段

陆宇航

2023-03-14

我对Android开发真的是一个新手，有几天我会尝试在我的应用程序中添加一个地图。我尝试了一些事情，但没有成功。如果有人能帮我，我很感激。

我做过的事：

将google-play-services_lib添加到我的包资源管理器中。
包含了android-support-v4.jar和google-play-services.jar作为我的项目的依赖项。

下面是main.xml文件

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

这里是清单文件

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

    <uses-sdk
     android:minSdkVersion="8"
     android:targetSdkVersion="17"/>

    <!-- The following four permissions -->
    <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"/>

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

    <application
            android:label="@string/app_name"
            android:icon="@drawable/ic_launcher">

        <meta-data
                android:name="com.google.android.maps.v2.API_KEY"
                android:value="AIzaSyDD0f1pf-64LHNlTUWl6a5qeoWqqMw0e3s"/>

        <activity
         android:name="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>
    </application>
</manifest>

最后是java

package com.example.hellomap;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;

public class MainActivity extends FragmentActivity {    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

试试我的另一个帖子。我已经详细解释了地图的工作。

你现在应该可以使用地图了。

想要使用GoogleMaps-OnMyLocationChangeListener但无法实现？任何其他选项

<fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="250dp"
        class="com.google.android.gms.maps.SupportMapFragment" />

权限如下所示：

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

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

    <permission
        android:name="com.mike.maps.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-permission android:name="com.example.mapsexample.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-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <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.mike.mylocation.HomeActivity"
            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.gms.version"
            android:value="@integer/google_play_services_version" />
        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="YOUE API WILL GO HERE" />
    </application>

</manifest>

也别忘了使用这些回调，否则你的电池会耗尽的…：p

    @Override
    protected void onPause() {

        super.onPause();
        locationManager.removeUpdates(this);

    }


    @Override
    protected void onDestroy() {
        // TODO Auto-generated method stub
        super.onDestroy();
        locationManager.removeUpdates(this);
    }


    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
                1, this);
    }
