我正在创建一个Android应用，我希望通过使用应用内结算来销售一些视频。我添加了应用内结算并且它正在运行，但如果我购买视频并退出应用程序，视频将再次付费，这意味着我需要再次购买。所以我想，如果一个用户购买视频，他总能看到它。这是我的代码。感谢。

答案 0 :(得分：0)
按下“购买”按钮，当用户点击该按钮时，请使用以下代码
SharedPreferences sp = getSharedPreferences("my_file", Context.MODE_PRIVATE);
sp.edit().putBoolean("key_video_buy", true).apply();
在您的onCreate()方法中，请使用此代码
boolean videoBought = getSharedPreferences("my_file", Context.MODE_PRIVATE).getBoolean"key_video_buy", false);
if (videoBought){
... //user bought the video already
}
else {
... //user hasn't bought it yet
}
