嘗試加載mapfragment時出錯

Question

我剛開始在android和im上使用片段，嘗試在片段活動中啓動地圖片段（在全屏幕上） - 我嘗試了所有內容 - 1. Myproject> Android的工具>添加支持庫 2.添加的支持和谷歌Play服務，因爲罐子\庫 3.重新啓動的Ecipse 似乎沒什麼幫助...... 連接的是我的logcat輸出 -

即佈局 -

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 

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

</RelativeLayout> 

和代碼 -

package com.telofun; 

import android.app.Dialog; 
import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 

import com.google.android.gms.common.ConnectionResult; 
import com.google.android.gms.common.GooglePlayServicesUtil; 
import com.google.android.gms.maps.GoogleMap; 
import com.google.android.gms.maps.SupportMapFragment; 
import com.google.android.gms.maps.model.Marker; 

public class FragmentMap extends FragmentActivity { 
    GoogleMap googleMap; 

    Marker marker = null; 


    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.fragment_map); 

     // Getting Google Play availability status 
     int status = GooglePlayServicesUtil 
       .isGooglePlayServicesAvailable(getBaseContext()); 

     // Showing status 
     if (status != ConnectionResult.SUCCESS) { // Google Play Services are 
                // not available 

      int requestCode = 10; 
      Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, 
        requestCode); 
      dialog.show(); 

     } else { // Google Play Services are available 

      // Getting reference to the SupportMapFragment of activity_main.xml 
      SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager() 
        .findFragmentById(R.id.map); 

      // Getting GoogleMap object from the fragment 
      googleMap = fm.getMap(); 

     } 

    } 
} 

Answer 1

更改此

class="com.google.android.gms.maps.MapFragment" 

到

class="com.google.android.gms.maps.SupportMapFragment" 

確保已正確引用谷歌播放服務庫項目。

Answer 2

正如Raghunandan所說，將MapFragment更改爲SupportMapFragment。但我認爲這並不簡單。我有同樣的錯誤，並嘗試像6個教程，並閱讀谷歌的所有文件。最後，我已經運行並顯示地圖。這是它對我的作用。

1.從eclipse和您的電腦中刪除Google-play-services和android support-v4庫。 2.從de sdk-manager下載它。 3.按照說明[此處]（https://developers.google.com/maps/documentation/android/intro#sample_code）轉到示例代碼並按照說明進行操作。特別檢查這個現有的Android代碼進入工作區，不要將這些庫作爲項目導入，它們將不起作用。 4.更改所有的MapFragment for SupportMapFragment，不要將你的Actvity擴展到FragmentActivity（那是我的失敗）。 5.禁用（如果啓用）項目中的自動構建選項。 6.清理項目。 5.啓用自動構建選項。 它應該工作。

如果它可以工作，但地圖不顯示，您應該轉到API CONSOL並打開Goog​​le Android Maps v2並關閉Google Maps v2。

希望你能解決它！
