RecyclerView 滑动时的优化处理，在滑动时停止加载图片，在滑动停止时开始加载图片，这里用了Glide.pause 和Glide.resume.这里为了避免重复设置增加开销，设置了一个标志变量来做判断。
mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
if (newState == RecyclerView.SCROLL_STATE_DRAGGING || newState == RecyclerView.SCROLL_STATE_SETTLING) {
sIsScrolling = true;
Glide.with(VipMasterActivity.this).pauseRequests();
} else if (newState == RecyclerView.SCROLL_STATE_IDLE) {
if (sIsScrolling == true) {
Glide.with(VipMasterActivity.this).resumeRequests();
}
sIsScrolling = false;
}
}
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
}
});
