请帮助我，我无法在android eclipse中显示谷歌地图。即使我创建了我的SHA1并转到谷歌控制台并为地图制作android键。
这是我的主要活动代码。
public class Main-Activity extends Activity {
// Google Map
private Google-Map google-Map;
@Override
protected void on-create(Bundle savedInstanceState) {
super.on-Create(savedInstanceState);
setContentView(R.layout.activity_main);
try {
// Loading map
initilizeMap();
// Changing map type
google-Map.setMapType(Google-Map.MAP_TYPE_NORMAL);
googleMap.setMyLocationEnabled(true);
googleMap.getUiSettings().setZoomControlsEnabled(false);
googleMap.getUiSettings().setMyLocationButtonEnabled(true);
on
googleMap.getUiSettings().setCompassEnabled(true);
googleMap.getUiSettings().setRotateGesturesEnabled(true);
googleMap.getUiSettings().setZoomGesturesEnabled(true);
double latitude = 17.385044;
double longitude = 78.486671;
// lets place some 10 random markers
for (int i = 0; i < 10; i++) {
// random latitude and logitude
double[] randomLocation = createRandLocation(latitude,
longitude);
// Adding a marker
MarkerOptions marker = new MarkerOptions().position(
new LatLng(randomLocation[0], randomLocation[1]))
.title("Hello Maps " + i);
Log.e("Random", "> " + randomLocation[0] + ", "
+ randomLocation[1]);
// changing marker color
if (i == 0)
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_AZURE));
if (i == 1)
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_BLUE));
if (i == 2)
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_CYAN));
if (i == 3)
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_GREEN));
if (i == 4)
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA));
if (i == 5)
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_ORANGE));
if (i == 6)
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_RED));
if (i == 7)
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_ROSE));
if (i == 8)
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_VIOLET));
if (i == 9)
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_YELLOW));
googleMap.addMarker(marker);
// Move the camera to last position with a zoom level
if (i == 9) {
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(new LatLng(randomLocation[0],
randomLocation[1])).zoom(15).build();
googleMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
protected void onResume() {
super.onResume();
initilizeMap();
}
/**
* function to load map If map is not created it will create it for you
* */
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
/*
* creating random postion around a location for testing purpose only
*/
private double[] createRandLocation(double latitude, double longitude) {
return new double[] { latitude + ((Math.random() - 0.5) / 500),
longitude + ((Math.random() - 0.5) / 500),
150 + ((Math.random() - 0.5) * 10) };
}
}
这是我的Xml部分::
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

android:layout_width="match_parent"

</RelativeLayout>
这是我的主要部分。

请建议我找出这个问题。我非常热衷于做这项工作所以请帮助我。这是我的android项目非常重要的部分，所以我在我的Android应用程序中获取此部分。在此先感谢帮助我解决这个问题。**
