在我运行地图应用程序时没有错误。不幸的是，当我在xml片段中添加一些属性时，它没有显示任何结果。我不知道为什么。我使用minSdkVersion=17和targetSdkVersion=21。请帮帮我。
这是Main.java
public class MainActivity extends FragmentActivity {
private static final int GPS_ERRORDIALOG_REQUEST = 9001;
GoogleMap gmap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(servicesOk())
{
setContentView(R.layout.activity_map);
if(InitMap())
{
Toast.makeText(this, "Ready to Map !", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(this, "Map not available !", Toast.LENGTH_SHORT).show();
}
}
else{
setContentView(R.layout.activity_main);
}
}
public boolean servicesOk(){
int isAvailable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if(isAvailable == ConnectionResult.SUCCESS){
return true;
}
else if(GooglePlayServicesUtil.isUserRecoverableError(isAvailable))
{
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvailable, this, GPS_ERRORDIALOG_REQUEST);
dialog.show();
}
else{
Toast.makeText(this, "Cannot connect to the Google Play Services",
Toast.LENGTH_SHORT).show();
}
return false;
}
private boolean InitMap(){
if(gmap== null)
{
SupportMapFragment mapFragment =
(SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
gmap = mapFragment.getMap();
}
return(gmap != null);
}
这是xml文件

尝试使用FrameLayout代替Fragment并将android:name="com.google.android.gms.maps.SupportMapFragment"更改为class="com.google.android.gms.maps.SupportMapFragment"
_mapFrag = new SupportMapFragment();
FragmentTransaction transaction = getSupportFragmentManager().BeginTransaction();
transaction.Replace(Resource.Id.map, _mapFrag);
