2.使用glide加载图片到非imageview

方式1.在监听器中加载背景图片

Glide.with(context)

.load(图片路径)

.listener(new RequestListener() {

@Override

public boolean onLoadFailed(@Nullable GlideException e, Object model, Targettarget, boolean isFirstResource) {

//失败加载的默认图片

activityLayout.setBackground(getResources().getDrawable(R.drawable.defaultbackground));

return false;

}

@Override

public boolean onResourceReady(Drawable resource, Object model, Targettarget, DataSource dataSource, boolean isFirstResource) {

//成功加载的图片

activityLayout.post(()->{

activityLayout.setBackground(resource);

});

return true;

}

})

.into(1024, 600);

方式二  通过 SimpleTarget

Glide.with(context)

.load(图片路径)

.into(new SimpleTarget() {

@Override

public void onResourceReady(@NonNull Drawable resource, @Nullable Transition super Drawable> transition) {

activityLayout.setBackground(resource);

}

});
