Glide占位符不适合ImageView

Question

这是我的代码

 Glide.with(context)
.load(url)
.asBitmap()
.placeholder(resourceId);
.centerCrop()
.into(new BitmapImageViewTarget(imageView) {
      @Override
      protected void setResource(Bitmap resource) {
          RoundedBitmapDrawable circularBitmapDrawable =
               RoundedBitmapDrawableFactory.create(imageView.getResources(),
               resource);
          circularBitmapDrawable.setCircular(true);
          imageView.setImageDrawable(circularBitmapDrawable);
      }
  });

每当我调用此函数加载用户头像时，placeHolder被删除，我的ImageView显示为空背景视图，而url加载并下载图像放在ImageView上。

尝试覆盖onLoadStarted方法，并在其中设置占位符图像。

Glide.with(context)
                .load(url)
                .diskCacheStrategy(DiskCacheStrategy.SOURCE)
                .into(new GlideDrawableImageViewTarget(imageView) {
                    @Override
                    public void onResourceReady(GlideDrawable drawable, GlideAnimation anim) {
                        super.onResourceReady(drawable, anim);

                    }

                    @Override
                    public void onLoadFailed(Exception e, Drawable errorDrawable) {
                        super.onLoadFailed(e, errorDrawable);
                        imageView.setImageResource(R.drawable.avatar);
                    }

                    @Override
                    public void onLoadStarted(Drawable placeholder) {
                        super.onLoadStarted(placeholder);
                        imageView.setImageResource(R.drawable.avatar);
                    }
                });

给loadId加载...

Glide
 .with(context)
 .load(resourceId)
 .placeholder(resourceId)
 .fitCenter()
 .into(new BitmapImageViewTarget(imageView) {
  @Override
  protected void setResource(Bitmap resource) {
      RoundedBitmapDrawable circularBitmapDrawable =
           RoundedBitmapDrawableFactory.create(imageView.getResources(),
           resource);
      circularBitmapDrawable.setCircular(true);
      imageView.setImageDrawable(circularBitmapDrawable);
  }
});
