使用android将图像加载到地图标记中

Question

我正在尝试添加位图到谷歌地图标记图标。

下面是我将图像添加到标记图标的代码。由于位图大小，应用程序正在崩溃

错误：java。lang.IllegalArgumentException：尺寸为4096x8192的纹理大于支持的最大尺寸4096x4096

BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        int imageHeight = options.outHeight;
        int imageWidth = options.outWidth;
        String imageType=options.outMimeType;
        if(imageWidth > imageHeight) {
            options.inSampleSize = calculateInSampleSize(options,10,10);//if landscape
        } else{
            options.inSampleSize = calculateInSampleSize(options,10,10);//if portrait
        }
        options.inJustDecodeBounds = false;


        Bitmap  mapbitmap = BitmapFactory.decodeFile("/storage/emulated/0/Pictures/TAG_IMG_25.2571724_55.2994563.jpg", options);

latLng=new LatLng(25.254376, 55.2973058);

marker = googleMap.addMarker(new MarkerOptions()
            .position(latLng)
            .title(_title)
            .snippet("dubai")
            .icon(BitmapDescriptorFactory.fromBitmap(mapbitmap)));

public static int calculateInSampleSize(
            BitmapFactory.Options options, int reqWidth, int reqHeight) {
        // Raw height and width of image
        final int height = options.outHeight;
        final int width = options.outWidth;
        int inSampleSize = 1;

        if (height > reqHeight || width > reqWidth) {

            // Calculate ratios of height and width to requested height and width
            final int heightRatio = Math.round((float) height / (float) reqHeight);
            final int widthRatio = Math.round((float) width / (float) reqWidth);

            // Choose the smallest ratio as inSampleSize value, this will guarantee
            // a final image with both dimensions larger than or equal to the
            // requested height and width.
            inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
        }

        return inSampleSize;
    }

Answer 1

答案就在你的问题本身。

Textures with dimensions4096x8192 are larger than the maximum supported size 4096x4096

因此，必须使用任何图像编辑器（如Photoshop）将图像大小减小到4096x4096以下。

如果你不熟悉，这里有一个教程。
