在活动的第3个开始时加载非页内广告

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(); } } 

我已经准备好启动我的应用程序，但希望它是正确的，并且不要让所有位置弹出的用户烦扰，以便控制何时加载！ 在一项活动上，我希望在该活动开始的第三次加载插页式广告！ 到目前为止，我已经在活动开始时加载了广告，但此刻每次都在启动。

 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(); } }

您可以在android中使用SharedPreferences 。 每当用户打开特定活动时，增加存储在sharedpreferences中作为计数器的字段。 同时，请经常检查计数器。 然后，当其达到三个时，加载非页内广告。

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。 每次活动开始时都放置以下代码

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();
