glide的error和placeholder支持.9patch

代码如下：

Glide.with(mContext)
    .load(imgUrl)
    .into(new DrawableImageViewTarget(iv) {
        @Override
        public void onLoadStarted(@Nullable Drawable placeholder) {
            LogUtils.e(TAG, "onLoadStarted");
            super.onLoadStarted(placeholder);
            view.setBackground(mContext.getResources().getDrawable(R.drawable.common_img_imageloder_default));
        }

        @Override
        public void onLoadFailed(@Nullable Drawable errorDrawable) {
            LogUtils.e(TAG, "onLoadFailed");
            super.onLoadFailed(errorDrawable);
            view.setBackground(mContext.getResources().getDrawable(R.drawable.common_img_imageloder_default));
        }

        @Override
        public void onResourceReady(@NonNull Drawable resource, @Nullable Transition<? super Drawable> transition) {
            LogUtils.e(TAG, "onResourceReady");
            view.setBackground(resource);
        }

        @Override
        public void onLoadCleared(@Nullable Drawable placeholder) {
            LogUtils.e(TAG, "onLoadCleared");
            super.onLoadCleared(placeholder);
            view.setBackground(null);
        }
    });
