您好我想在页面中添加地图(静态图片)。我将尝试解释到目前为止我所做的事情,以及我的问题是否能得到解决,以防其他人在将来遇到同样的问题。
我做了以下事情: 1.使用权限/ API更新了清单文件(使用来自Eclipse的SHA1使用Window> Preferences> Build获取API(来自Google API控制台)密钥 2.更新了将添加地图的类的XML文件 3.在Java文件类
中添加了一些Java代码以下是清单文件:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="net.learn2develop.lapmaster"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk

android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="@drawable/lapmaster_icon"

android:theme="@style/AppTheme" >

</activity>

<meta-data

android:value="@integer/google_play_services_version" />
<meta-data

android:required="true" />
</application>
</manifest>
以下是XML类:
<?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.SupportMapFragment" />
以下是Java类:
import android.app.Activity;
import android.os.Bundle;
import com.google.android.gms.maps.SupportMapFragment;
public class Snetterton extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.snetterton);
SupportMapFragment map = ((SupportMapFragment)
.getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
}
}
正如您可能从我的代码中猜到的那样,我正在为赛道创建一个应用程序。在名为Snetterton的课程中,我想添加一张Snetterton的图片(谷歌地图)。
要到达此页面,用户: 1.从登录屏幕开始(LapMasterActivity) 2.迎接主页(UserLoggedInScreen) 3.转到带有曲目列表的页面(现在只是Snetterton)(ListOFTracks) 4.当用户单击Snetterton的按钮时,它会将它们带到Snetterton类的页面,我想要地图。 (斯内特顿)。
仅在我的代码中((SupportMapFragment)带下划线。
感谢。
答案 0 :(得分:0)
自己回答(最终):
我使用的代码是:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/relativeLayoutFragment"
android:layout_width="match_parent"
android:layout_height="fill_parent" >
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
public class TopGear extends Activity
{
private GoogleMap aMap;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.top_gear);
aMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
aMap.getUiSettings().setAllGesturesEnabled(false);
LatLng topGearTrack = new LatLng(51.116492, -0.541767);
aMap.setMyLocationEnabled(true);
aMap.moveCamera(CameraUpdateFactory.newLatLngZoom(topGearTrack, 15));
aMap.addMarker(new MarkerOptions()
.title("Top Gear")
.snippet("Welcome to the famous Top Gear circuit.")
.position(topGearTrack));
aMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
setUpMapIfNeeded();
}
public void setUpMapIfNeeded()
{
//Do a null check to confirm that we have not already instantiated the map.
if (aMap == null)
{
aMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
.getMap();
//Check if we were successful in obtaining the map.
if (aMap != null)
{
//The Map is verified. It is now safe to manipulate the map.
}
}
}
}
