1、下载Glide的jar包,地址:http://pan.baidu.com/s/1ge8ptIV
2、导入eclipse
3、创建类BlurTransformation继承import com.bumptech.glide.load.resource.bitmap.BitmapTransformation;
package com.it.utils; import com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool; import com.bumptech.glide.load.resource.bitmap.BitmapTransformation; import android.content.Context; import android.graphics.Bitmap; import android.renderscript.Allocation; import android.renderscript.Element; import android.renderscript.RenderScript; import android.renderscript.ScriptIntrinsicBlur; public class BlurTransformation extends BitmapTransformation { private RenderScript rs; public BlurTransformation(Context context) { super(context); rs = RenderScript.create( context ); } @Override protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) { Bitmap blurredBitmap = toTransform.copy( Bitmap.Config.ARGB_8888, true ); // Allocate memory for Renderscript to work with Allocation input = Allocation.createFromBitmap( rs, blurredBitmap, Allocation.MipmapControl.MIPMAP_FULL, Allocation.USAGE_SHARED ); Allocation output = Allocation.createTyped(rs, input.getType()); // Load up an instance of the specific script that we want to use. ScriptIntrinsicBlur script = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs)); script.setInput(input); // Set the blur radius script.setRadius(20); // Start the ScriptIntrinisicBlur script.forEach(output); // Copy the output to the blurred bitmap output.copyTo(blurredBitmap); toTransform.recycle(); return blurredBitmap; } @Override public String getId() { return "blur"; } } 4、使用Glide.with(this).load(picUrl).bitmapTransform(new BlurTransformation(this), new CenterCrop(this)).into(layCover);
其中picUrl为图片URL,layCover为加载图片的ImageView
