android - 點擊時顯示的插頁式廣告

Question

在我的新游戲中，我想展示插頁式廣告。 單擊按鈕，游戲會重新啟動，我希望廣告僅每 15 次出現一次。 問題是每次游戲開始時都會顯示它。 錯在哪里？

public class MainActivity extends AppCompatActivity {
 
    InterstitialAd mInterstitialAd;
    public int playcount = 0;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_game);
        mInterstitialAd = new InterstitialAd(this);

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

        AdRequest adRequest = new AdRequest.Builder()
            .build();

        // Load ads into Interstitial Ads
        mInterstitialAd.loadAd(adRequest);
        TextView playctv = (TextView) findViewById(R.id.textView);

        SharedPreferences prefsplay = this.getSharedPreferences("myPrefsKey",
            Context.MODE_PRIVATE);
        playcount = prefsplay.getInt("play_number", 0);
        playctv.setText(String.valueOf(playcount));
    }

    public void restart(View view) {
        Intent intent = new Intent(this, GameScreen.class);
        startActivity(intent);
        playcount++;

        SharedPreferences prefsplay = this
            .getSharedPreferences("myPrefsKey",
                    Context.MODE_PRIVATE);
        prefsplay.edit().putInt("play_number", playcount)
            .apply();
    }

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

    private void adView() {
        mAdView = (AdView) findViewById(R.id.adView);
        MobileAds.initialize(getApplicationContext(), getResources().getString(R.string.interstitial_full_screen));
        final AdRequest adRequest = new AdRequest.Builder().build();
        mAdView.loadAd(adRequest);
    }

    public void gameover() { 
        if (playcount == 10) {
            playcount = 0;
            mInterstitialAd.setAdListener(new AdListener() {
                public void onAdLoaded() {
                    mInterstitialAd.show();    //We are executing this code only if ad is loaded, no need to check it again

                    SharedPreferences prefsplay = getApplicationContext()
                        .getSharedPreferences("myPrefsKey",
                                Context.MODE_PRIVATE);
                    prefsplay.edit().putInt("play_number", playcount)
                        .apply();

                    AdRequest adRequest = new AdRequest.Builder()
                        .build();
                }
            });
        }
    }
}

您的代碼需要大量修復。 我在這里一一貼。

• restart函數應該使用startActivityForResult

   private final int ACTION_GAME = 100; public void restart(View view) { Intent intent = new Intent(this, GameScreen.class); startActivityForResult(intent, ACTION_GAME); playcount++; SharedPreferences prefsplay = this .getSharedPreferences("myPrefsKey", Context.MODE_PRIVATE); prefsplay.edit().putInt("play_number", playcount).apply(); }

• 當您為結果啟動GameScreen活動時，您需要覆蓋onActivityResult

   @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) { case ACTION_GAME: gameover(); break; default: break; } }

• 現在，在gameover功能，你需要在你的偏愛，檢查保存的值playcount 。

   public void gameover() { // Get the saved value SharedPreferences prefsplay = this .getSharedPreferences("myPrefsKey", Context.MODE_PRIVATE); playcount = prefsplay.getInt("play_number", 0); if (playcount >= 10) { playcount = 0; showInterstitial(); SharedPreferences prefsplay = getApplicationContext() .getSharedPreferences("myPrefsKey", Context.MODE_PRIVATE); prefsplay.edit().putInt("play_number", playcount).apply(); // Start loading the new ad loadNewAd(); } }

• 我已經引入了loadNewAd()函數，它看起來像這樣

  private void loadNewAd() { final AdRequest adRequest = new AdRequest.Builder().build(); mAdView.loadAd(adRequest); }

• 而onCreate函數需要這樣修改

  @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_game); mInterstitialAd = new InterstitialAd(this); // set the ad unit ID mInterstitialAd.setAdUnitId(getString(R.string.interstitial_full_screen)); // Call adView here adView(); TextView playctv = (TextView) findViewById(R.id.textView); SharedPreferences prefsplay = this.getSharedPreferences("myPrefsKey", Context.MODE_PRIVATE); playcount = prefsplay.getInt("play_number", 0); playctv.setText(String.valueOf(playcount)); }

• 最后，當您使用startActivityForResult您需要在完成GameScreen活動時設置結果。 因此，當您完成或從GameScreen活動返回時，您需要執行此操作。

   GameScreen.setResult(Activity.RESULT_OK); GameScreen.finish();
