我是StackOverflow的新手，对不起我可能出现的错误。
我只想在我的应用程序中插入一个简单的Google地图。
我犯了这个错误：
java.lang.RuntimeException：无法启动活动 ComponentInfo {com.example.luiza.mapagps / com.example.luiza.mapagps.GPS}： android.view.InflateException：二进制XML文件行＃12：二进制XML 文件行＃12：错误膨胀类片段
我的xml是：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.luiza.mapagps.GPS">
<fragment
android:id="@+id/mapGoogle"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment"/>
</RelativeLayout>
我已经尝试过使用：android:name="com.google.android.gms.maps.MapFragment"
这是我的 MainActivity.java：
package com.example.luiza.mapagps;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.CameraPosition;
import com.google.android.gms.maps.model.MarkerOptions;
import com.google.android.gms.maps.model.LatLng;
public class GPS extends FragmentActivity
implements OnMapReadyCallback
{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gps);
MapFragment mapFragment = (MapFragment) getFragmentManager()
.findFragmentById(R.id.mapGoogle);
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap map) {
map.addMarker(new MarkerOptions()
.position(new LatLng(0, 0))
.title("Here"));
map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
CameraPosition googlePlex = CameraPosition.builder()
.target(new LatLng(37.4219999,-122.0862462))
.zoom(16)
.bearing(0)
.tilt(45)
.build();
map.moveCamera(CameraUpdateFactory.newCameraPosition(googlePlex));
}
}
这是我的 Manifest：
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">

<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.geo.Im using my API"
android:value="I'm using my API"/>
</application>
<uses-feature

android:required="true"/>

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
</manifest>
这是我的 Build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.2"
defaultConfig {
applicationId "com.example.luiza.mapagps"
minSdkVersion 19
targetSdkVersion 24
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.google.android.gms:play-services-maps:9.4.0'
我试过了：
清理并重建项目;
使用：compile＆＃39; com.google.android.gms：play-services-maps：9.4.0＆＃39;
更改android：name和class
导入android.support.v4.app.Fragment;
将此添加到清单文件：

我真的需要帮助，我知道有很多类似的问题，但没有人回答我的问题。
提前谢谢。
我不是来自北美，对于任何英语错误都很抱歉。
答案 0 :(得分：2)
添加地图片段的权限：
<permission
android:name="com.example.luiza.mapagps.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.luiza.mapagps.permission.MAPS_RECEIVE" />
在您的布局文件中，将fragment更改为SupportMapFragment
<SupportMapFragment
android:id="@+id/mapGoogle"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment"/>
java.lang.RuntimeException：找不到API密钥。检查它是否在AndroidManifest.xml的元素中
显示日志。你遗失API_KEY：
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="some_key_here"/>
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
