我正在尝试创建一个在用户进行购买时停用广告的应用。但是，广告甚至不会显示应用程序当前启动的时间。
如果我将其放在onCreate方法中，则广告只会在用户启动应用时加载。 （当用户点击删除广告按钮时，广告就会消失。）
mAdView = (AdView) findViewById(R.id.adView);
adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
这是我的MainActivity.class
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
IabHelper mHelper;
AdView mAdView;
MenuItem menuItem2;
AdRequest adRequest;
NavigationView nvDrawer;
DrawerLayout mDrawer;
RelativeLayout myView;

SharedPreferences.Editor editor;
IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener;
CoordinatorLayout container;
private ActionBarDrawerToggle drawerToggle;

final String mIsPremium = "purchased";
@SuppressWarnings("ConstantConditions")
@Override

我要做的是为iap事件的共享pref删除添加，然后在用户执行iap时更改它....然后在onCreate上检查它是否禁用广告并相应地设置{ {1}}根据共享的首选项在布局中添加容器。
尝试只调用一次SharedPreference，然后使用编辑器提交数据：
Visibilty = "GONE"这是针对onCreate
SharedPreference SP;
SP = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
editor = SP.edit();
//...
editor.putString("abc", udata);
editor.commit();
//...
editor.putStringSet("si",ssetdata)
editor.commit();
