Question

在我的Android Quiz应用中，我实施了Admob。但每次给出答案并且问题发生变化时，Admob也会刷新，这需要大约3-4秒。但到那时问题再次发生变化，等等。

QuestionActivity.class：

虽然问题正在发生变化，但广告是否可以展示整个时间？

谢谢

Answer 1

尝试删除

  adView.loadAd(new AdRequest());

来自你的onCreate并添加

ads:loadAdOnCreate="true"

到你的广告XML。

Answer 2

您的问题是您正在#onClick中开始新的活动。不要启动新的Activity，重用当前的Activity。

在这种情况下，例如：

@Override
public void onClick(View arg0) {
    //Log.d("Questions", "Moving to next question");

    /**
     * validate a checkbox has been selected
     */
    if (!checkAnswer()) return;


    /**
     * check if end of game
     */
    if (currentGame.isGameOver()){
        Intent i = new Intent(this, EndgameActivity.class);
        startActivity(i);
        finish();
    }
    else{
        currentQ = currentGame.getNextQuestion(); 
        setQuestions();
    }
}
