我正在尝试让 Android ' Google Maps Android API v2 ' 的示例代码工作。我得到的项目没有错误。但是,当我尝试在 Everpad 设备中运行该应用程序时,该应用程序立即崩溃。这是 :

- java代码

   package com.dvp.android.gallery;

    public class GPS extends Activity {
          static final LatLng HAMBURG = new LatLng(53.558, 9.927);
          static final LatLng KIEL = new LatLng(53.551, 9.993);
          private GoogleMap map;

      @Override
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gps);
        map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
            .getMap();
        Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
            .title("Hamburg"));
        Marker kiel = map.addMarker(new MarkerOptions().position(KIEL).title("Kiel").snippet("Kiel is cool").icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_launcher)));

        // Move the camera instantly to hamburg with a zoom of 15.
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

        // Zoom in, animating the camera.
        map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
      }


}

使用 FragmentActivity 扩展您的 Activity,并将您的布局地图 ID 称为 SupportMapFragment。

/** * @author manish * */

public class DrawMap extends FragmentActivity implements OnMapClickListener,
        OnMapLongClickListener {

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

SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        googleMap = fm.getMap();
        googleMap.setMyLocationEnabled(true);
        googleMap.setOnMapClickListener(this);
        googleMap.setOnMapLongClickListener(this);
    }

还有你的 xml-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <fragment android:id="@+id/map" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" class="com.google.android.gms.maps.SupportMapFragment" /> </RelativeLayout>

你只需要Activity扩展FragmentActivity而不是Activity

这是因为 Google Map 类有一个片段,为此您必须导入android.support.v4。jar 文件...并将地图添加到您的布局中,作为您需要使用 FragmentActivity 扩展的片段
