在mapview上的地圖圖像數據完成後，我應該在哪寫代碼以關閉ProgressDialog？

Question

我在setContentView之後立即設置ProgressDialog以彈出ProgressDialog。

在mapview上完成地圖圖像數據後，我想調用方法來關閉ProgressDialog。

我想知道我應該在哪寫代碼來解僱它。

我已經寫下了這些源代碼。 如果你幫我，我很感激。

謝謝。

這裏是我的地圖活動類：

package sample.MyMap; 

import sample.MyMap.R; 
import com.google.android.maps.MapActivity; 
import com.google.android.maps.MapController; 
import com.google.android.maps.MyLocationOverlay; 
import android.app.Dialog; 
import android.app.ProgressDialog; 
import android.content.Intent; 
import android.os.Bundle; 
import android.util.Log; 

public class MyMapActivity extends MapActivity { 
    private MyMapView map; 
    private MapController controller; 
    private ProgressDialog progressDialog; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     Log.d("TEST", this + " onCreate"); 
     setContentView(R.layout.main); 
     progressDialog = ProgressDialog.show(this, "Please wait...", "Loading map view ...", true); 
     initMapView(); 
     initMyLocation(); 
    } 

    @Override 
    protected boolean isRouteDisplayed() { 
     return false; 
    } 

    private void initMapView() { 
     map = (MyMapView) findViewById(R.id.map); 
     controller = map.getController(); 
     map.setSatellite(false); 
     map.setBuiltInZoomControls(true); 
    } 

    private void initMyLocation() { 
     final MyLocationOverlay overlay = new MyLocationOverlay(this, map); 
     overlay.enableMyLocation(); 
     overlay.enableCompass(); 
     overlay.runOnFirstFix(new Runnable() { 

      public void run() { 
       controller.setZoom(18); 
       controller.animateTo(overlay.getMyLocation()); 
      } 
     }); 
     map.getOverlays().add(overlay); 
    } 

} 

這裏是我的MapView類：

package sample.MyMap; 

import android.content.Context; 
import android.util.AttributeSet; 
import android.util.Log; 

import com.google.android.maps.MapView; 

public class MyMapView extends MapView { 

    public MyMapView(Context context, String apiKey) { 
     super(context, apiKey); 
    } 

    public MyMapView(Context context, AttributeSet attrs, int defStyle) { 
     super(context, attrs, defStyle); 
    } 

    public MyMapView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
    } 

    @Override 
    protected void onDetachedFromWindow() { 
     super.onDetachedFromWindow(); 
     Log.d("TEST", "onDetachedFromWindow"); 
    } 

    @Override 
    protected void onSizeChanged(int w, int h, int oldw, int oldh) { 
     super.onSizeChanged(w, h, oldw, oldh); 
     Log.d("TEST", "onSizeChanged"); 
    } 

    @Override 
    public void onWindowFocusChanged(boolean hasFocus) { 
     super.onWindowFocusChanged(hasFocus); 
     Log.d("TEST", "onWindowFocusChanged"); 
    } 

    @Override 
    public void preLoad() { 
     super.preLoad(); 
     Log.d("TEST", "preLoad"); 
    } 

}

把你initMapView & initMyLocation方法在這次會議之後，如下面代碼&所述hod關閉下面定義的對話框

new Thread(new Runnable() 
{ 
    public void run() 
    { 
     initMapView(); 
     initMyLocation(); 
     progressDialog.dismiss(); 
    } 
}).start();
