谷歌地圖不被顯示;灰色瓷磚

Question

我正在嘗試谷歌地圖使用教程，但它不顯示地圖;只是灰色的瓷磚。請幫助我..我的項目因此被卡住了。

這是我的代碼

以下是我再次嘗試編輯的代碼。請看看代碼和logcat文件。

請參閱此處，只需在清單文件中使用您的密鑰更改api密鑰，並按照以下步驟操作： 並確保您的google_play_services_lib項目僅應存在於項目工作空間中。

清單文件：

<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); 
    } 

} 

activity_main.xml中：

<?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"/> 

了之後這讓我知道。

由於您的清單設置不正確，導致地圖無法正常工作。用戶this tutorial從Android文檔，並確保您啓用所需的確切權限。你的API密鑰也在錯誤的地方。它進入你的清單，而不是片段。

Answer 3

在某些設備上加載時，Google地圖版本2存在一些問題，您只需重新啓動設備即可開始工作。
