本頁面有MapView時要將Activity改MapActivity
監聽GPS要加入 implements LocationListener
public class fgs2 extends MapActivity implements LocationListener {
int lv = 7;
LocationManager locm = null;
@Override protected void onCreate( Bundle savedInstanceState ) {
super.onCreate( savedInstanceState );
this.locm = (LocationManager)this.getSystemService( Context.LOCATION_SERVICE );
this.locm.requestLocationUpdates( LocationManager.GPS_PROVIDER , 0 , 0 , this );
this.setContentView( R.layout.main );
MapView mv = (MapView)this.findViewById( R.id.mapv );
mv.setBuiltInZoomControls( true );
mv.setSatellite( true );// 使用衛星圖
MapController mc = mv.getController();
//設定Zoom大小和地圖的中心點
mc.setZoom( this.lv );
mc.setCenter( new GeoPoint( 23828194 , 120800899 ) );
}
@Override protected void onPause() { //暫停
if ( this.locm != null ) {
this.locm.removeUpdates( this );
}
super.onPause();
}
@Override protected void onResume() { //恢復暫停
if ( this.locm != null ) {
this.locm.requestLocationUpdates( LocationManager.GPS_PROVIDER , 0 , 0 , this );
}
super.onResume();
}
@Override protected void onDestroy() { //終止前記得關閉GPS監聽
if ( this.locm != null ) {
this.locm.removeUpdates( this );
}
super.onDestroy();
}
@Override public void onLocationChanged( Location loc ) {
MapController mc = ( (MapView)this.findViewById( R.id.mapv ) ).getController();
mc.animateTo( new GeoPoint( (int)( loc.getLatitude() * 1E6 ) , (int)( loc.getLongitude() * 1E6 ) ) );
// mc.setZoom( 17 );
}
@Override public void onProviderDisabled( String provider ) {
}
@Override public void onProviderEnabled( String provider ) {
}
@Override public void onStatusChanged( String provider , int status , Bundle extras ) {
}
@Override protected boolean isRouteDisplayed() {
return false;
}
}
