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

</RelativeLayout>

这是我的主要部分。

    </application>

</manifest>

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。**
