Question

我搜索了所有地方但是因为Glide已经发布了4.4版本。我找不到再应用RoundedCornersTransformation的方法了。我正在使用glide-transformations，即使在他们的Github论坛上也没有正确的解决方案。

此前：

GlideApp.with(context)
.load(url)
.transforms(new CenterCrop(), new RoundedCorners(radius))
.into(imageView);

然后更新它必须像这样调用：

Glide.with(context)
   .load(url)
   .apply(new RequestOptions().transforms(new CenterCrop(), new RoundedCorners(radius)))
   .into(imageView);

但是对于Glide 4.4，我面临一个问题：

1：根本不应用转换。

2：如果我尝试使用.transforms API，它似乎就不再可用了！

如果有人可以提供帮助，请回复。如果找到了，我会发布我的回复！

Answer 1

以下是我在项目的github opened issues上阅读的内容。

你可以使用Glide的RoundedCorners转换。请注意，centerCrop（）正在覆盖以前的转换。所以你可以使用：

 Glide.with(context)
   .load(url)
   .apply(new RequestOptions().transforms(new CenterCrop(), new RoundedCorners(radius)))
   .into(imageView);

但不幸的是，Glide没有transforms()但只有transform()方法。

因此，我检查了我的代码，发现在我使用的ImageView中：

android:scaleType="centerCrop"

结果我的转换被这个属性覆盖了，就像上面论坛的评论中提到的那样。

centerCrop（）正在覆盖先前的转换

最终解决方案：我在布局xml中删除了scaleType="centerCrop"中的ImageView并编写了我的代码。

RequestOptions options = new RequestOptions();
                options.placeholder(R.drawable.place_holder)
                        .diskCacheStrategy(DiskCacheStrategy.AUTOMATIC)
                        .error(R.drawable.error_place_holder)
                        .transform(new CenterCrop())
                        .transform(new RoundedCorners(corner_size));

                Glide.with(mActivity).load(url)
                        .apply(options)
                        .into(image_view);

瞧！它奏效了！

注意： centerCrop()对于不同的用例可能会有不同的效果。

Answer 2

根据GitHub https://github.com/bumptech/glide中的说明，使用此功能。

圆形图片：已知CircleImageView / CircularImageView / RoundedImageView与TransitionDrawable（.crossFade（）与.thumbnail（）或.placeholder（））和动画GIF有关，使用BitmapTransformation（。 circleCrop（）将在v4）或.dontAnimate（）中提供以解决问题。

希望得到这个帮助。

修改： 我试过你想要的，看看下面。使用 https://github.com/bumptech/glide 和 https://github.com/wasabeef/glide-transformations 。

<强> MainActivity.java

package com.demo;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ImageView;

import com.bumptech.glide.Glide;
import com.bumptech.glide.request.RequestOptions;

public class MainActivity extends AppCompatActivity {

ImageView imageView, imageView2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    imageView = (ImageView) findViewById(R.id.imageView);
    imageView2 = (ImageView) findViewById(R.id.imageView2);


   Glide.with(this).load(R.mipmap.company_bg)
            .apply(RequestOptions.bitmapTransform(new CircleCrop()))
            .into(imageView);

   //this also works for Circle crop as above
     //Glide.with(this).load(R.mipmap.company_bg)
     //       .apply(RequestOptions.circleCropTransform())
     //       .into(imageView);


    Glide.with(this).load(R.mipmap.company_bg)
            .apply(RequestOptions.bitmapTransform(new RoundedCornersTransformation(45, 0, RoundedCornersTransformation.CornerType.ALL)))
            .into(imageView2);

  }
}

在 build.gradle 文件

中

 implementation 'com.github.bumptech.glide:glide:4.4.0'
 implementation 'jp.wasabeef:glide-transformations:3.0.1'

这里是截图图片的样子。

我正在使用更新版本的滑翔，我已经使用此代码实现了RoundCornerTransformation。检查这是否可以帮助你..

将此java类放在常量文件中

public class RoundedCornersTransformation implements Transformation<Bitmap> {

  public enum CornerType {
    ALL,
    TOP_LEFT, TOP_RIGHT, BOTTOM_LEFT, BOTTOM_RIGHT,
    TOP, BOTTOM, LEFT, RIGHT,

  }

  public RoundedCornersTransformation(Context context, int radius, int margin,

使用此代码应用转化

 Glide.with(this)
                .load("url")
                ..bitmapTransform(new RoundedCornersTransformation(context, 4, 0,
                    RoundedCornersTransformation.CornerType.ALL))
                .into(imageView);

那＆＃34; 4＆＃34;显示圆形的角半径...... 希望这对你有所帮助，如果不是让我知道......

Answer 4

尝试一下：

Glide.with(CreateRecipe.this)
    .load(yourbitmap)
    .diskCacheStrategy(DiskCacheStrategy.ALL)
    .placeholder(R.drawable.yourplaceholder)
    .transform(new CenterCrop(), new Rotate(90))
    .into(yourimageviewer);

Answer 5

重要的部分是组合变换。我能够使用以下块同时使centerCrop和RoundedCorners工作：

                            GlideApp.with(context)
                                    .load(glideUrl)
                                    .diskCacheStrategy(DiskCacheStrategy.ALL)
                                    .placeholder(R.drawable.ic_placeholder)
                                    .transforms(new CenterCrop(), new RoundedCorners(1))
                                    .into(holder.imageView);

Answer 6

首先，将此库添加到构建包中：

implementation 'jp.wasabeef:glide-transformations:4.0.0'

第二，将此代码添加到您的代码中：

 Glide.with(this)
                .asBitmap()
                .load(R.drawable.time_watch)
                .apply(new RequestOptions().transform(new BlurTransformation(50)))
                .into(imgFestivalBanner);

在Glide 4.4上无法使用滑行变换
