Question

我开发了一个应用程序，我需要查看Google Maps v2 主要课程是：

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;
import android.os.Bundle; 
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import android.app.Activity; 

public class MapsV2 extends FragmentActivity {     

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mapsv2);    

    mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
    mMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
    final LatLng CIU = new LatLng(35.21843892856462, 33.41662287712097);
    Marker ciu = mMap.addMarker(new MarkerOptions()
                              .position(CIU).title("My Office"));
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main_page_option_menu, menu);
    return true;
    }
}

XML是：

<?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"
      class="com.google.android.gms.maps.SupportMapFragment"
      android:name="com.app.reminder.MapsV2"/>

所以，当我在我的设备上运行时，我收到了错误消息：

清单是：

我尝试了StackOverFlow中答案中的所有选项。

Answer 1

你应该替换这个

 mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

用

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

Answer 2

日志很清楚，你在清单中缺少这一行：

<meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

正如您可以在本行末尾阅读：

Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value.  Expected 4132500 but found 0.  You must have the following declaration within the <application> element:<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

另外，请注意使用最新版本的Google Play服务（版本13或更高版本），而不是不包含该参数的Froyo 的Google Play服务。

Answer 3

替换你的片段

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

在manifest.xml中

   <uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="19" />

活动类

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

GoogleMap gMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

在Google Maps V2上输入类片段时出错
