所以，我想制作一个带有显示奖励广告的简单按钮的应用程序。该按钮有效并显示奖励广告，但是当我再次按下时，没有显示奖励广告。我想为每个按钮点击展示广告。
这是代码：
public class MainActivity extends AppCompatActivity {
private RewardedAd rewardedAd;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.button);
TextView textView = (TextView) findViewById(R.id.textView);
rewardedAd = new RewardedAd(this,
"ca-app-pub-3940256099942544/5224354917");
final RewardedAdLoadCallback[] adLoadCallback = {new RewardedAdLoadCallback() {
@Override
public void onRewardedAdLoaded() {
// Ad successfully loaded.
}
@Override
public void onRewardedAdFailedToLoad(LoadAdError adError) {
// Ad failed to load.
}
}};
rewardedAd.loadAd(new AdRequest.Builder().build(), adLoadCallback[0]);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (rewardedAd.isLoaded()) {
Activity activityContext = MainActivity.this;
RewardedAdCallback adCallback = new RewardedAdCallback() {
@Override
public void onRewardedAdOpened() {
// Ad opened.
}
@Override
public void onRewardedAdClosed() {
}
@Override
public void onUserEarnedReward(@NonNull RewardItem reward) {
}
@Override
public void onRewardedAdFailedToShow(AdError adError) {
// Ad failed to display.
}
};
rewardedAd.show(activityContext, adCallback);
} else {
Log.d("TAG", "The rewarded ad wasn't loaded yet.");
}
}
});
}
}
我没有设置奖励，首先我希望按钮能够显示多个广告
