  1. /**
  2.  * @param context Context to create the {@link RenderScript}
  3.  */
  4. @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR1)
  5. public RenderScriptBlur(Context context) {
  6.   renderScript = RenderScript.create(context);
  7.   blurScript = ScriptIntrinsicBlur.create(renderScript, Element.U8_4(renderScript));
  8. }

代码示例来源：origin: HotBitmapGG/bilibili-android-client

  1. /**
  2.    * 图片高斯模糊具体实现方法
  3.    */
  4.   public static Bitmap blur(Context context, Bitmap image, float radius) {
  5.     // 计算图片缩小后的长宽
  6.     int width = Math.round(image.getWidth() * BITMAP_SCALE);
  7.     int height = Math.round(image.getHeight() * BITMAP_SCALE);
  8.     // 将缩小后的图片做为预渲染的图片。
  9.     Bitmap inputBitmap = Bitmap.createScaledBitmap(image, width, height, false);
  10.     // 创建一张渲染后的输出图片。
  11.     Bitmap outputBitmap = Bitmap.createBitmap(inputBitmap);
  12.     // 创建RenderScript内核对象
  13.     RenderScript rs = RenderScript.create(context);
  14.     // 创建一个模糊效果的RenderScript的工具对象
  15.     ScriptIntrinsicBlur blurScript = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));
  16.     // 由于RenderScript并没有使用VM来分配内存,所以需要使用Allocation类来创建和分配内存空间。
  17.     // 创建Allocation对象的时候其实内存是空的,需要使用copyTo()将数据填充进去。
  18.     Allocation tmpIn = Allocation.createFromBitmap(rs, inputBitmap);
  19.     Allocation tmpOut = Allocation.createFromBitmap(rs, outputBitmap);
  20.     // 设置渲染的模糊程度, 25f是最大模糊度
  21.     blurScript.setRadius(radius);
  22.     // 设置blurScript对象的输入内存
  23.     blurScript.setInput(tmpIn);
  24.     // 将输出数据保存到输出内存中
  25.     blurScript.forEach(tmpOut);
  26.     // 将数据填充到Allocation中
  27.     tmpOut.copyTo(outputBitmap);
  28.     return outputBitmap;
