使用Glide库显示模糊图像 [英] Show Blur Image Using Glide library

问题描述

我尝试使用 Glide 显示模糊图像，但显示错误图像.我不知道为什么显示错误图像. URL 可以正常工作，但仍然它只显示错误图片

i'm trying to show blur image using Glide but instead showing error images.i have no idea why it is show error image.URL is working fine but still it is showing error image only

这是我的代码

 Glide.with(context)
                .load("http://www.gadgetsaint.com/wp-content/uploads/2016/11/cropped-web_hi_res_512.png")
                .diskCacheStrategy(DiskCacheStrategy.NONE)
                .bitmapTransform(new BlurTransformation(context))
                .error(R.drawable.error_image)
                .into(imageView);

BlurTransformation类:

public class BlurTransformation extends BitmapTransformation {

private RenderScript rs;

public BlurTransformation(Context context) {
    super(context);

    rs = RenderScript.create(context);
}

@SuppressLint("NewApi")
@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(100);

    // 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";
}
}

推荐答案

1. 添加此库: implementation 'jp.wasabeef:glide-transformations:4.0.0 对于最新版本，请始终从此处检查更改日志滑行转换
2. 在需要模糊图像的地方，请在您的视图中应用此代码

1. Add this library : implementation 'jp.wasabeef:glide-transformations:4.0.0 For latest version always check change log from here Glide transformation
2. And where u need to blur image apply this code in your view

    Glide.with(this)
     .load(R.drawable.demo)
     .apply(bitmapTransform(BlurTransformation(25, 3)))
     .into(imageView)
