在活动第 3 次开始时加载插页式 admob 广告

Question

public class Starting extends ActionBarActivity {

    private final String PREFERENCE_NAME = "ad_counter_preference"; //class level variable
    private final String COUNTER_INTERSTITIAL_ADS = "ad_counter"; //class level variable
    private int mAdCounter = 0; //class level variable

    //adview
    private AdView mAdView;

    //interstitial
    private String TAG = Starting.class.getSimpleName();
    InterstitialAd mInterstitialAd;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_starting);

        mAdView = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder()
                .build();
        mAdView.loadAd(adRequest);

        //interstitial
        mInterstitialAd = new InterstitialAd(this);
        mInterstitialAd = new InterstitialAd(this);

        // set the ad unit ID
        mInterstitialAd.setAdUnitId(getString(R.string.interstitial_full_screen));


        // Load ads into Interstitial Ads
        mInterstitialAd.loadAd(adRequest);

        mInterstitialAd.setAdListener(new AdListener() {
            public void onAdLoaded() {
                showInterstitial();
            }
        });

        SharedPreferences preferences = getSharedPreferences(PREFERENCE_NAME, Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = preferences.edit();

        editor.putInt(COUNTER_INTERSTITIAL_ADS, mAdCounter);
        editor.commit();

        mAdCounter = preferences.getInt(COUNTER_INTERSTITIAL_ADS, 0);

        if (mAdCounter == 3) {
            // Load interstitial ad now
         showInterstitial();
            mAdCounter = 0; //Clear counter variable
        } else {
            mAdCounter++; // Increment counter variable
        }

        // Save counter value back to SharedPreferences
        editor.putInt(COUNTER_INTERSTITIAL_ADS, mAdCounter);
        editor.commit();

    }




    private void showInterstitial() {
        if (mInterstitialAd.isLoaded()) {
            mInterstitialAd.show();
        }
    }


//banner ads
    @Override
    public void onPause() {
        if (mAdView != null) {
            mAdView.pause();
        }
        super.onPause();
    }

    @Override
    public void onResume() {
        super.onResume();
        if (mAdView != null) {
            mAdView.resume();
        }
    }

    @Override
    public void onDestroy() {
        if (mAdView != null) {
            mAdView.destroy();
        }
        super.onDestroy();
    }
}

我正准备启动我的应用程序，但希望它是正确的，并且不会因为插页式广告到处弹出而惹恼用户，所以我想控制它们何时加载！在一项活动中，我希望在活动开始的第 3 次加载插页式广告！到目前为止，我已经让广告在活动开始时加载，但现在它每次都开始。

public class Starting extends ActionBarActivity {

    //adview
    private AdView mAdView;

    //interstitial
    private String TAG = Starting.class.getSimpleName();
    InterstitialAd mInterstitialAd;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_starting);

        mAdView = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder()
                .build();
        mAdView.loadAd(adRequest);

        //interstitial
        mInterstitialAd = new InterstitialAd(this);
        mInterstitialAd = new InterstitialAd(this);

        // set the ad unit ID
        mInterstitialAd.setAdUnitId(getString(R.string.interstitial_full_screen));

       
        // Load ads into Interstitial Ads
        mInterstitialAd.loadAd(adRequest);

        mInterstitialAd.setAdListener(new AdListener() {
            public void onAdLoaded() {
                showInterstitial();
            }
        });
    }
    private void showInterstitial() {
        if (mInterstitialAd.isLoaded()) {
            mInterstitialAd.show();
        }
    }


//banner ads
    @Override
    public void onPause() {
        if (mAdView != null) {
            mAdView.pause();
        }
        super.onPause();
    }

    @Override
    public void onResume() {
        super.onResume();
        if (mAdView != null) {
            mAdView.resume();
        }
    }

    @Override
    public void onDestroy() {
        if (mAdView != null) {
            mAdView.destroy();
        }
        super.onDestroy();
    }
}

Answer 1

您可以在 android 中使用 SharedPreferences。 每当用户打开特定活动时，递增存储在用作计数器的 sharedpreferences 中的字段。 同时，随时检查计数器。当它达到三个时，加载插页式广告。

您可以参考以下代码：

public class Starting extends ActionBarActivity {

private final String PREFERENCE_NAME = "ad_counter_preference";
private final String COUNTER_INTERSTITIAL_ADS = "ad_counter";
private int mAdCounter = 0;

private InterstitialAd mInterstitialAd;
private AdRequest mInterstitialAdRequest;
private AdRequest mBannerAdRequest;
private AdView mAdView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.second);

    loadInterstitialAd();
    loadBannerAd();

    SharedPreferences preferences = getSharedPreferences(PREFERENCE_NAME, Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = preferences.edit();

    mAdCounter = preferences.getInt(COUNTER_INTERSTITIAL_ADS, 0);

    if (mAdCounter == 3) {
        // Load interstitial ad now
        mInterstitialAd.setAdListener(new AdListener() {
            public void onAdLoaded() {
                showInterstitial();
            }
        });
        mAdCounter = 0; //Clear counter variable
    } else {
        mAdCounter++; // Increment counter variable
    }

    // Save counter value back to SharedPreferences
    editor.putInt(COUNTER_INTERSTITIAL_ADS, mAdCounter);
    editor.commit();
}

private void loadInterstitialAd() {
    mInterstitialAdRequest = new AdRequest.Builder()
            .build();

    //interstitial
    mInterstitialAd = new InterstitialAd(this);

    // set the ad unit ID
    mInterstitialAd.setAdUnitId("Your Ad unit Id");

    // Load ads into Interstitial Ads
    mInterstitialAd.loadAd(mInterstitialAdRequest);
}

private void loadBannerAd() {
    mAdView = (AdView) findViewById(R.id.adView);
    mBannerAdRequest = new AdRequest.Builder()
            .build();
    mAdView.loadAd(mBannerAdRequest);
}

private void showInterstitial() {
    if (mInterstitialAd.isLoaded()) {
        mInterstitialAd.show();
    }
}

@Override
public void onPause() {
    if (mAdView != null) {
        mAdView.pause();
    }
    super.onPause();
}

@Override
public void onResume() {
    super.onResume();
    if (mAdView != null) {
        mAdView.resume();
    }
}

@Override
public void onDestroy() {
    if (mAdView != null) {
        mAdView.destroy();
    }
    super.onDestroy();
}}

我建议使用 SharedPreferences。每次活动开始时输入以下代码

SharedPreferences preferences = context.getSharedPreferences("MyPreferences", Context.MODE_PRIVATE);  
SharedPreferences.Editor editor = preferences.edit();

int displayTimes = preferences.getInt("kDisplayTimes", 0); 

if (displayTimes == 3) {
    // Shown 3 times, reset counter
    displayTimes = 0;

    // Show interstitial
}
else {
    // Less than 3 times, increase counter
    displayTimes++;
}

// Save counter back to SharedPreferences
editor.putInt("kDisplayTimes", displayTimes);
editor.commit();
