终于做到了。因此，您要做的是有一个背景图像（在我的情况下，我仅使用一个蓝色矩形）。像这样创建一个标记：Marker myLocMarker = map.addMarker(new MarkerOptions() .position(myLocation) .icon(BitmapDescriptorFactory.fromBitmap(writeTextOnDrawable(R.drawable.bluebox, "your text goes here"))));请注意writeTextOnDrawable（）方法：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.setStyle(Style.FILL); paint.setColor(Color.WHITE); 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) ;}
