如何在recyclerview中限制原生广告的数量 我只想在recyclerview的前100行中使用5个原生广告（每20行一次）。 我的Recyclerview有10000排。它每20行广告输出就会使用户烦恼。所以我想将广告数量限制为5.我做了很多改变，但我做不到。 提前感谢您的帮助
我的活动中与广告相关的部分
public static final int ITEMS_PER_AD = 20;
private static final int NATIVE_EXPRESS_AD_HEIGHT = 100;
private void addNativeExpressAds() {
// Loop through the items array and place a new Native Express ad in every ith position in
// the items List.
for (int i = 0; i <= mRecyclerViewItems.size(); i += ITEMS_PER_AD) {
final NativeExpressAdView adView = new NativeExpressAdView(getActivity());
mRecyclerViewItems.add(i, adView);
}
}
private void setUpAndLoadNativeExpressAds() {
mRecyclerView.post(new Runnable() {
@Override
public void run() {
try {
for (int i = 0; i <= mRecyclerViewItems.size(); i += ITEMS_PER_AD) {
final NativeExpressAdView adView = (NativeExpressAdView) mRecyclerViewItems.get(i);
AdSize adSize = new AdSize(AdSize.FULL_WIDTH, NATIVE_EXPRESS_AD_HEIGHT);
adView.setAdSize(adSize);
adView.setAdUnitId(AD_UNIT_ID);
}
loadNativeExpressAd(0);
}catch (Exception e){
}
}
});
}
private void loadNativeExpressAd(final int index) {
// if (index >= mRecyclerViewItems.size()) {
// return;
// }
if (index >= mRecyclerViewItems.size()) {
return;
}
Object item = mRecyclerViewItems.get(index);
if (!(item instanceof NativeExpressAdView)) {
throw new ClassCastException("Expected item at index " + index + " to be a Native"
+ " Express ad.");
}
final NativeExpressAdView adView = (NativeExpressAdView) item;
// Set an AdListener on the NativeExpressAdView to wait for the previous Native Express ad
// to finish loading before loading the next ad in the items list.
adView.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
super.onAdLoaded();
// The previous Native Express ad loaded successfully, call this method again to
// load the next ad in the items list.
if (index<24){
loadNativeExpressAd(index + ITEMS_PER_AD);
}
}
@Override
public void onAdFailedToLoad(int errorCode) {
// The previous Native Express ad failed to load. Call this method again to load
// the next ad in the items list.
Log.e("MainActivity", "The previous Native Express ad failed to load. Attempting to"
+ " load the next Native Express ad in the items list.");
//loadNativeExpressAd(index + ITEMS_PER_AD);
}
