自定义地图标记

Question

我有一个带有标记的地图视图。我想知道是否可以将其他字符串值添加到诸如电话号码和网站等标记。点击标记时，我不希望这些信息显示在信息窗口中。当点击信息窗口时，它会转到所选标记的详细活动。标记标题和代码片段作为附加内容传递给细节活动，我想另外传递两个附加字符串作为附加内容。

这里是我创造的标志：

for(int i = 0; i < Lat.length; i++) { 
      Marker marker = map.addMarker(new MarkerOptions() 
      .position(new LatLng(Lat[i], Lon[i])) 
      .title(Market[i]) 
      .snippet(Address[i]) 
      .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE))); 

      list.add(marker); 
     } 

这里是我开始了详细的活动。

map.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() { 
      @Override 
      public void onInfoWindowClick(Marker marker) { 
       // Show Details 
       Intent intent = new Intent(getActivity(), FarmMarketDetails.class); 
       intent.putExtra("selectedTitle", marker.getTitle()); 
       intent.putExtra("selectedAddress", marker.getSnippet()); 
       startActivity(intent); 
      } 
     });

我创建的自定义标记用下面的代码，请检查是否是有帮助的，你自定义标记

private Bitmap writeTextOnDrawable(int drawableId, String text) { 

     Bitmap bm = BitmapFactory.decodeResource(getResources(), drawableId) 
       .copy(Bitmap.Config.ARGB_8888, true); 

     Typeface tf = Typeface.create("Helvetica", Typeface.BOLD); 

     Paint paint = new Paint(); 

     paint.setColor(Color.BLUE); 
     paint.setTypeface(tf); 
     paint.setTextAlign(Align.CENTER); 
     paint.setTextSize(convertToPixels(context,11)); 

     Rect textRect = new Rect(); 
     paint.getTextBounds(text, 0, text.length(), textRect); 

     Canvas canvas = new Canvas(bm); 

     //If the text is bigger than the canvas , reduce the font size 
     if(textRect.width() >= (canvas.getWidth() - 4))  //the padding on either sides is considered as 4, so as to appropriately fit in the text 
      paint.setTextSize(convertToPixels(context,7));  //Scaling needs to be used for different dpi's 

     //Calculate the positions 
     int xPos = (canvas.getWidth()/2) - 2;  //-2 is for regulating the x position offset 

     //"- ((paint.descent() + paint.ascent())/2)" is the distance from the baseline to the center. 
     int yPos = (int) ((canvas.getHeight()/2) - ((paint.descent() + paint.ascent())/2)) ; 

     canvas.drawText(text, xPos, yPos, paint); 

     return bm; 
    } 

    public static int convertToPixels(Context context, int nDP) 
    { 
     final float conversionScale = context.getResources().getDisplayMetrics().density; 

     return (int) ((nDP * conversionScale) + 0.5f) ; 

    }
