在创建应用程序的过程中，我遇到了一些代码问题，最重要的是，用户打开应用程序时按下“获取”按钮，观看广告视频并收到促销代码，但是如果该人关闭广告或收到促销代码而无法打开电影，则面临一个问题，第二个问题与页面更新的实现有关；我使用了SwipeRefresh布局动画，但是没有更新。
应用代码：
public class MainActivity extends AppCompatActivity implements RewardedVideoAdListener {
private static final String TAG = "MainActivity";
AdView mAdView;
Button mButtonGive, mButtonOrig, mButtonAmedia, mButtonIvi;
TextView mTextPromo;
RewardedVideoAd mAd;
ClipboardManager clipboardManager;
ClipData clipData;
FirebaseFirestore mRef = FirebaseFirestore.getInstance();
DocumentReference mPapaRef = mRef.collection("Promocode").document("Papa_Johns");
SwipeRefreshLayout mSwipeRefresh;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mButtonGive = findViewById(R.id.mButtonGivePapa);
mTextPromo = findViewById(R.id.mTextPromoPapa);
mButtonOrig = findViewById(R.id.mButtonBuyOrig);
mButtonAmedia = findViewById(R.id.mButtonBuyAmedia);
mButtonIvi = findViewById(R.id.mButtonBuyIvi);
mSwipeRefresh = findViewById(R.id.swipeRefresh);
mSwipeRefresh.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
Log.i(TAG, "onRefresh called from SwipeRefreshLayout");
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
mSwipeRefresh.setRefreshing(false);
}
}, 3000);
}
});
mSwipeRefresh.setColorSchemeResources(R.color.colorLight, R.color.colorMiddle, R.color.colorPrimary);
MobileAds.initialize(this, "ca-app-pub-7120970387686966~9640430308");
