android - 使用应用内计费隐藏广告横幅

Question

在用户使用应用内结算进行购买后，如何删除横幅广告和 TextView 。用户付款后，横幅和文本确实消失了，但一旦他们终止应用程序并再次打开，横幅和 TextView 仍然显示，但不同的是当他们点击 TextView 时， toast “谢谢for your purchase” 显示，然后文本和横幅消失。我怎样才能让它们在 oncreate 时完全不出现。谢谢

主要

public class MainActivity extends AppCompatActivity implements BillingProcessor.IBillingHandler{
BillingProcessor bp;
AdView Adview;
TextView textView6;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    bp = new BillingProcessor(this, "YOUR LICENSE KEY FROM GOOGLE PLAY CONSOLE HERE", this);
    MobileAds.initialize(this,"ca-app-pub-3940256099942544~3347511713");
    Adview=findViewById(R.id.adView);
    textView6=findViewById(R.id.textView6);
    AdRequest adRequest = new AdRequest.Builder()/*.addTestDevice("")*/.build();
    Adview.loadAd(adRequest);

}
public void onClickAds(View view){
    bp.purchase(MainActivity.this, "android.test.purchased");
}

@Override
public void onProductPurchased(@NonNull String productId, @Nullable TransactionDetails details) {

    Toast.makeText(this, "Thank you for your purchase",Toast.LENGTH_LONG).show();
    ViewGroup parent1 = (ViewGroup) Adview.getParent();
    ViewGroup parent2 = (ViewGroup) textView6.getParent();
    parent1.removeView(Adview);
    parent2.removeView(textView6);
    parent1.invalidate();
    parent2.invalidate();
    }

@Override
public void onPurchaseHistoryRestored() {

}

@Override
public void onBillingError(int errorCode, @Nullable Throwable error) {
    Toast.makeText(this, "AN ERROR OCCURED.",Toast.LENGTH_LONG).show();
}

@Override
public void onBillingInitialized() {

}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (!bp.handleActivityResult(requestCode, resultCode, data)) {
        super.onActivityResult(requestCode, resultCode, data);
    }
}
@Override
public void onDestroy() {
    if (bp != null) {
        bp.release();
    }
    super.onDestroy();
}

Answer 1

尝试使用共享偏好来解决这个问题

下面的步骤对你有帮助

步骤 1. 在顶部初始化

private static final String PREF_FILE  = "PREF_FILE";
private static final String IS_PRODUCT_PURCHASE = "IS_PRODUCT_PURCHASE";

第 2 步。在 onProductPurchased() 方法中添加这些行

SharedPreferences.Editor editor = getSharedPreferences(PREF_FILE, MODE_PRIVATE).edit();
    editor.putBoolean(IS_PRODUCT_PURCHASE,true);
    editor.commit();

setp 3.最后在onCreate()中调用这个方法

private void checkForIsPurchase() {
    SharedPreferences preferences = getSharedPreferences(PREF_FILE, MODE_PRIVATE);
    boolean isPurchase = preferences.getBoolean(IS_PRODUCT_PURCHASE, false);
    if (isPurchase) {
        Adview.setVisibility(View.GONE);
        textView6.setVisibility(View.GONE);
    }
}
