我正在尝试使用GlideLibrary加载占位符图像,并且正在使用SimpleTarget。占位符图像未加载,但URL中的图像正在加载。我已经搜索了很多,也使用了RequestOptions。不过,它似乎不起作用。
下面是代码:
Glide.with(mContext).load("https://i.imgur.com/0k7ZFWr.png").apply(RequestOptions.placeholderOf(R.drawable.pubgguide_icon)).into(new SimpleTarget<Drawable>() {
@Override
public void onResourceReady(Drawable resource, Transition<? super Drawable> transition) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
holder.cardImageLayout.setBackground(resource);
Drawable cardViewBackground = holder.cardImageLayout.getBackground();
cardViewBackground.setColorFilter(0x5F000000, PorterDuff.Mode.SRC_ATOP);
}
}
});
我正在使用Glide库4.7.1。我也尝试过使用setDefaultRequestOptions()-不起作用。

placeHolderOf
仅在将其加载到ImageView
中时设置占位符图像。如果要将占位符设置为ViewGroup,则SimpleTarget
类提供了一种方法,可以在图像开始加载时覆盖该方法以设置背景。
在您的情况下,请尝试按以下方式加载:
Glide.with(mContext)
.load("https://i.imgur.com/0k7ZFWr.png")
.apply(RequestOptions.placeholderOf(R.drawable.pubgguide_icon))
.into(new SimpleTarget<Drawable>() {
@Override
public void onLoadStarted(@Nullable Drawable resource) {
holder.cardImageLayout.setBackground(resource);
}
@Override
public void onResourceReady(@NonNull Drawable resource, Transition<? super Drawable> transition) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
holder.cardImageLayout.setBackground(resource);
Drawable cardViewBackground = holder.cardImageLayout.getBackground();
cardViewBackground.setColorFilter(0x5F000000, PorterDuff.Mode.SRC_ATOP);
}
}
});

您可以使用Glide(4.7.1)
Glide.with(getActivity()).load(avatar)
.apply(RequestOptions.bitmapTransform(new CircleCrop()).placeholder(R.mipmap.defaultusericon))
.into(mUserIcon);
