我想在RecyclerView中加载广告广告已成功加载,但在滚动时会出现这么多延迟
以下是我在Adapter的OnBindViewHolder方法中编写的代码
如何解决这个滞后？
((DealHolder) holder).adcardView.post(new Runnable() {
@Override
public void run() {
final NativeExpressAdView adView = new NativeExpressAdView(((DealHolder) holder).itemView.getContext());
final int adWidth = ((DealHolder) holder).adcardView.getWidth() - ((DealHolder) holder).adcardView.getPaddingLeft()
- ((DealHolder) holder).adcardView.getPaddingRight();
final int adHeight = ((DealHolder) holder).adcardView.getHeight() - ((DealHolder) holder).adcardView.getPaddingBottom()
- ((DealHolder) holder).adcardView.getPaddingTop();
final float scale = ((DealHolder) holder).adcardView.getResources().getdisplayMetrics().density;
AdSize adSize = new AdSize((int) (adWidth / scale),(int) (adHeight / scale));
adView.setAdSize(adSize);
adView.setAdUnitId(((DealHolder) holder).adcardView.getContext().getString(R.string.test_adunit_id));
AdRequest request = new AdRequest.Builder().addTestDevice("jjhjhbjhjhjhjhjhjhjh").build();
adView.loadAd(request);
adView.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
super.onAdLoaded();
}
@Override
public void onAdFailedToLoad(int i) {
super.onAdFailedToLoad(i);
}
});
((DealHolder) holder).adcardView.removeAllViews();
((DealHolder) holder).adcardView.addView(adView);
}
});
解决方法
改进：
>当用户尝试滚动时,请勿尝试加载Adview.为此,使您的适配器recylerView滚动识别,然后检查是否scroll_state == RecylerView.Scroll_IDLE,然后只加载您的AdView.>如果您的所有adView具有相同的宽度和高度,则每次用户滚动时都不会计算它,请将其缓存在变量中.>不要动态添加和删除NativeExpressAdView,而是在item_view中使用XML版本.您可以根据条件隐藏和显示.在XML视图中设置所有可能的必需属性.
