谷歌Android API＆QUOT;无法加载地图＆QUOT;

本文介绍了谷歌Android API＆QUOT;无法加载地图＆QUOT;的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想谷歌显示地图的地图。

我跟着这个。

我修正了一些问题和应用程序运行，但我无法显示地图。

下面我所做的：


  • 创建谷歌的控制台上的API项目

  • 创建一个ID

  • 激活谷歌地图Android版API V2的服务

  • 生成新的Andr​​oid键

  • 在清单
    • 进口这一关键
  • 随后这段视频，安装库

在这里，我的.java：

 公共类MainActivity扩展FragmentActivity {私有静态GoogleMap的MMAP = NULL;@覆盖
保护无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.activity_main）;    INT状态= GooglePlayServicesUtil.isGooglePlayServicesAvailable（getApplicationContext（））;    如果（状态== ConnectionResult.SUCCESS）{
       如果（MMAP == NULL）{          MMAP =（（SupportMapFragment）getSupportFragmentManager（）findFragmentById（R.id.map）。）的GetMap（）;          如果（MMAP！= NULL）{
            UiSettings设置= mMap.getUiSettings（）;            settings.setZoomControlsEnabled（真）;
            settings.setCompassEnabled（真）;
            settings.setRotateGesturesEnabled（真）;
            settings.setTiltGesturesEnabled（真）;
            settings.setScrollGesturesEnabled（真）;
            settings.setZoomControlsEnabled（真）;
            settings.setZoomGesturesEnabled（真）;
            settings.setMyLocationButtonEnabled（假）;            mMap.setMapType（GoogleMap.MAP_TYPE_NORMAL）;
            mMap.setMyLocationEnabled（假）;
            }
          }
       }
    }
    保护无效onResume（）{
        super.onResume（）;        INT状态= GooglePlayServicesUtil.isGooglePlayServicesAvailable（getApplicationContext（））;        如果（状态== ConnectionResult.SUCCESS）{
           如果（MMAP == NULL）{              MMAP =（（SupportMapFragment）getSupportFragmentManager（）findFragmentById（R.id.map）。）的GetMap（）;              如果（MMAP！= NULL）{
                UiSettings设置= mMap.getUiSettings（）;                settings.setZoomControlsEnabled（真）;
                settings.setCompassEnabled（真）;
                settings.setRotateGesturesEnabled（真）;
                settings.setTiltGesturesEnabled（真）;
                settings.setScrollGesturesEnabled（真）;
                settings.setZoomControlsEnabled（真）;
                settings.setZoomGesturesEnabled（真）;
                settings.setMyLocationButtonEnabled（假）;                mMap.setMapType（GoogleMap.MAP_TYPE_NORMAL）;
                mMap.setMyLocationEnabled（假）;
              }
          }
     }
 }

我activity_main.xml中：

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT; LinearLayout中的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
    机器人：layout_width =FILL_PARENT

解决方案

您的应用程序标签内（在清单）地址：

 ＆LT;使用库机器人：名字=com.google.android.maps/＆GT;

这个替换您的XML片段：

 ＆LT;片段
      机器人：ID =@ + ID /图
      机器人：layout_width =match_parent
      机器人：layout_height =match_parent
      类=com.google.android.gms.maps.SupportMapFragment
    /＆GT;

让您的活动延长FragmentActivity和的onCreate和onResume称之为code：

  INT状态= GooglePlayServicesUtil.isGooglePlayServicesAvailable（getApplicationContext（））;如果（状态== ConnectionResult.SUCCESS）{
   如果（MMAP == NULL）{      MMAP =（（SupportMapFragment）getSupportFragmentManager（）findFragmentById（R.id.map）。）的GetMap（）;      如果（MMAP！= NULL）{
        UiSettings设置= mMap.getUiSettings（）;        settings.setZoomControlsEnabled（真）;
        settings.setCompassEnabled（真）;
        settings.setRotateGesturesEnabled（真）;
        settings.setTiltGesturesEnabled（真）;
        settings.setScrollGesturesEnabled（真）;
        settings.setZoomControlsEnabled（真）;
        settings.setZoomGesturesEnabled（真）;
        settings.setMyLocationButtonEnabled（假）;        mMap.setMapType（GoogleMap.MAP_TYPE_NORMAL）;
        mMap.setMyLocationEnabled（假）;
      }
    }
}

不要忘了你的声明MMAP变量：

 私人GoogleMap的MMAP;

I'm trying to display Google Map's map.

I followed this tutorial.

I Fixed some problems and the application runs, but I could not display the map.

Here what I did:

  • Created an API project on the google console
  • Created an ID
  • Activated "Google Maps Android API v2" service
  • Generated new Android key
  • Imported this key in manifest
  • Followed this video to install the library

And here my .java:

public class MainActivity extends FragmentActivity {

private static GoogleMap mMap = null;

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

    int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

    if(status == ConnectionResult.SUCCESS){
       if (mMap == null) {

          mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

          if (mMap != null) {
            UiSettings settings = mMap.getUiSettings();

            settings.setZoomControlsEnabled(true);
            settings.setCompassEnabled(true);
            settings.setRotateGesturesEnabled(true);
            settings.setTiltGesturesEnabled(true);
            settings.setScrollGesturesEnabled(true);
            settings.setZoomControlsEnabled(true);
            settings.setZoomGesturesEnabled(true);
            settings.setMyLocationButtonEnabled(false);

            mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
            mMap.setMyLocationEnabled(false);
            }
          }
       }
    }
    protected void onResume() {
        super.onResume();

        int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

        if(status == ConnectionResult.SUCCESS){
           if (mMap == null) {

              mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

              if (mMap != null) {
                UiSettings settings = mMap.getUiSettings();

                settings.setZoomControlsEnabled(true);
                settings.setCompassEnabled(true);
                settings.setRotateGesturesEnabled(true);
                settings.setTiltGesturesEnabled(true);
                settings.setScrollGesturesEnabled(true);
                settings.setZoomControlsEnabled(true);
                settings.setZoomGesturesEnabled(true);
                settings.setMyLocationButtonEnabled(false);

                mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
                mMap.setMyLocationEnabled(false);
              }
          }
     }
 }

my activity_main.xml:

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


</LinearLayout>

And my manifest:

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

    <permission android:name="com.example.map.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
    <uses-permission android:name="com.example.map.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"/>

    <uses-sdk
        android:minSdkVersion="12"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <uses-library android:name="com.google.android.maps" />
        <activity
            android:name="com.example.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="<MyKey>"/>

    </application>

</manifest>
解决方案

Inside your application tag (in manifest) add:

<uses-library android:name="com.google.android.maps" />

Replace your fragment XML by this:

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

Let your activity extend FragmentActivity and onCreate and onResume call this code:

int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

if(status == ConnectionResult.SUCCESS){
   if (mMap == null) {

      mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

      if (mMap != null) {
        UiSettings settings = mMap.getUiSettings();

        settings.setZoomControlsEnabled(true);
        settings.setCompassEnabled(true);
        settings.setRotateGesturesEnabled(true);
        settings.setTiltGesturesEnabled(true);
        settings.setScrollGesturesEnabled(true);
        settings.setZoomControlsEnabled(true);
        settings.setZoomGesturesEnabled(true);
        settings.setMyLocationButtonEnabled(false);

        mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        mMap.setMyLocationEnabled(false);
      }
    }
}

Don't forget to declare your mMap variable like this:

private GoogleMap mMap;
