我用Androids Rederscript模糊了一个位图

private Bitmap createBitmap_ScriptIntrinsicBlur(Bitmap src, float r) {

    //Radius range (0 < r <= 25)
    if(r <= 0){
        r = 0.1f;
    }else if(r > 25){
        r = 25.0f;
    }
    Bitmap bitmap = Bitmap.createBitmap(src.getWidth(), src.getHeight(),Bitmap.Config.ARGB_8888);

    RenderScript renderScript = RenderScript.create(getActivity());

    Allocation blurInput = Allocation.createFromBitmap(renderScript, src);
    Allocation blurOutput = Allocation.createFromBitmap(renderScript, bitmap);

    ScriptIntrinsicBlur blur = ScriptIntrinsicBlur.create(renderScript,Element.U8_4(renderScript));
    blur.setInput(blurInput);
    blur.setRadius(r);
    blur.forEach(blurOutput);

    blurOutput.copyTo(bitmap);
    renderScript.destroy();
    return bitmap;
}

但图像不够模糊.有没有可能模糊半径超过25的图像.当我多次调用模糊功能时,图像会像单个函数调用一样模糊.所以这也不起作用.
谢谢您的帮助.
