通过Zoom缩放地图标记，Android [英] Scale Map Markers by Zoom, Android

问题描述

我的地图上有很多标记.放大每个标记会显示一个位置.但是缩小标记会相互重叠，因此确定标记的位置会更加困难.

I have lot of markers on my map. Zooming in each marker shows me a position. but zooming out the markers are overlapping each other and it is more difficult do determine the position of a marker.

有没有一种方法可以根据缩放比例缩放标记图像?

Is there a way to scale the marker image depending on the zoom factor?

推荐答案

取决于绘制标记的方式.如果您的标记只是位图/可绘制对象，只需使用 matrix.postScale()

Depends on how you draw your marker. If your marker is just a bitmap/drawable, simply use matrix.postScale()

Matrix matrix = new Matrix();
matrix.postScale(2f, 2f); // douple the size
canvas.drawBitmap(mBitmap, matrix, mPaint);
