Android画布试图绘制太大的异常

Answer 1

在执行任何操作之前，请尝试压缩您选择的图像。

这是压缩等宽高比图像的代码。

我已将Uri转换为位图

bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);

resizeBitmap = resize(bitmap, bitmap.getWidth() / 2, bitmap.getHeight() / 2);

private static Bitmap resize(Bitmap image, int maxWidth, int maxHeight) {
    if (maxHeight > 0 && maxWidth > 0) {
        int width = image.getWidth();
        int height = image.getHeight();
        float ratioBitmap = (float) width / (float) height;
        float ratioMax = (float) maxWidth / (float) maxHeight;

        int finalWidth = maxWidth;
        int finalHeight = maxHeight;
        if (ratioMax > ratioBitmap) {
            finalWidth = (int) ((float) maxHeight * ratioBitmap);
        } else {
            finalHeight = (int) ((float) maxWidth / ratioBitmap);
        }
        image = Bitmap.createScaledBitmap(image, finalWidth, finalHeight, true);
        return image;
    } else {
        return image;
    }
}
