我有一个应用，在我的应用的几个页面上执行了一定数量的操作后显示插页式广告。我担心用户可能会在我的应用程序中闲逛，并且会在他们的脸上沾上一大堆插页式广告。
我如何限制每个会话的广告数量？比如，每次会话限制为2或3个插页式广告。
谷歌搜索这个问题让我得到了这个唯一相关的结果： https://groups.google.com/forum/#!topic/google-admob-ads-sdk/QZV3Z5Vy4pg
＆＃34;至于如何做到这一点，例如，您可以将计数器存储在共享偏好设置中，并在每次显示插页式广告时将其递增。如果您达到5，则可以暂时停止请求插页式广告。当应用程序再次启动时，可以清除计数器。＆＃34;
我是java代码/开发的新手，并且已经对SharedPreferences做了很多研究，但我对如何将它合并到我的代码中感到茫然。
如果有人可以帮助我走上正确的道路或者有更好的想法，我全都听见了！
谢谢！

答案 0 :(得分：0)
首先在您的oncreate中调用此 loadInterstitial(); 以初始加载您的添加
并且我的示例逻辑还有这样一个事实：如果您的按钮被点击了至少5次或小于6 ，您可以在if语句中更改它。
我摆脱了第一种方法..
使用共享偏好方法
SharedPreferences sp = getSharedPreferences("preference name", MODE_PRIVATE);
if(sp.getInt("key", 0) < any number here){
Editor ed = sp.edit();
ed.putInt("key",(sp.getInt("key", 0) +1));
ed.commit();
//do adds work
}
当你需要展示时调用它们，可能会放入一个方法

先生，您的代码非常好，只需按照这种方式进行修改
private void displayInterstitial(){
//sharedpreferences
//Here, SharedPreference is changed to SharedPreferences - thanks for changing it
SharedPreferences sp = getSharedPreferences("preference name", MODE_PRIVATE);
//I will try 1 ad per session - when you call show(), it shows one add, okay? so
if(sp.getInt("key", 0) < 5){ // the zero is the default value if it's empty, the if statement checks if your sp integer is less than 5.
// and continues if it checks true, if not, skip the whole statement, that's the logic here
Editor ed = sp.edit();
ed.putInt("key",sp.getInt("key", 0) +1);
//Here, ed.commint(): is changed to ed.commit(); -thanks once more- i looked stupid at first
ed.commit();
//do adds work - you should put your add code in this method below "do adds work"
if (interstitial.isLoaded() && counter < 5){ // that's your counter, the && checks if your first argument is true before it moves on to the
//second argument.. if it checks false, all is false & checks
// checks both arguments regardless of their outcome
interstitial.show();
loadInterstitial();
}
}
//end shared preferences, end of if-statement, end of logic code
} // end of method
if语句是检查器，如果if语句检查为false则不会显示add，只要你的int小于5，它就会一直检查为
A lso先生，创建getter和setter很容易，getter和setter只是帮助设置和检索变量/对象的一些功能，你可以通过声明你的变量/对象来创建一个，在那之后，在你的日食上去来源然后生成getter和setter ..它们将由eclipse生成 - （如果你使用eclipse，那就像其他ides一样）这很容易，还要注意你最初的方式非常好，只需要稍加改动
代码中的日志行以了解正在发生的事情
并且应该工作。 SIR TOM
