如何在Android中修复Google地图标记的自定义尺寸

Question

How do I set the marker size. Can anyone tell me?

Answer 1

It's happening because the icon you are using as a marker is bigger in size.So,You can first convert it into Bitmap and change its size and then use that bitmap in as a custom marker. For example I have made a method which resizes your bitmap and returns the resized bitmap.

public Bitmap resizeBitmap(String drawableName,int width, int height){
    Bitmap imageBitmap = BitmapFactory.decodeResource(getResources(),getResources().getIdentifier(drawableName, "drawable", getPackageName()));
    return Bitmap.createScaledBitmap(imageBitmap, width, height, false);
}

Then call this method in googleMap.addMarker()

googleMap.addMarker(new MarkerOptions()
            .title("New Marker").position(yourGivenPosition).icon(BitmapDescriptorFactory.fromBitmap(resizeBitmap("your drawable name",72,64))));

Answer 2

更改标记图像（图标）的尺寸，30 x 40我认为没问题

Answer 3

I assume you have a bmp image since you are setting a custom marker. To resize the bmp , use Bitmap.createScaledBitmap (Bitmap src, int width, int height, boolean filter)
