android界面中,已可显示地图,并可在地图中标注 "天府广场" 出来,
标注的代码如下:
class MyLocationOverlay extends Overlay 
        {             
public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when)    
{            
super.draw(canvas, mapView, shadow);           
Paint paint = new Paint();        
Point myScreenCoords = new Point(); 
mapView.getProjection().toPixels(mGeoPoint, myScreenCoords);            
paint.setStrokeWidth(1);           
paint.setARGB(255, 255, 0, 0);            
paint.setStyle(Paint.Style.STROKE);            
Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.icon);            
canvas.drawBitmap(bmp, myScreenCoords.x, myScreenCoords.y, paint);            
canvas.drawText("天府广场", myScreenCoords.x, myScreenCoords.y, paint);           
return true;        
}   
}现:1 目前 天府广场坐标不知显示的是什么位置
   2 需给  赋一坐标 (JINMXPJOJTHLLD KPGUVTJOLLLLL),如何弄呀,thanks
