        else if (resultCode == PaymentActivity.RESULT_PAYMENT_INVALID) {
            Log.i("paymentExample", "An invalid payment was submitted. Please see the docs.");

Answer 1

使用此选项获取默认首选项：

SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);

使用此选项保存值：

Editor edit = preferences.edit();
edit.putString("isPayed", "yes");
edit.apply();

这将检索值：preferences.getString("isPayed", "No");

Answer 2

您可以尝试使用SharedPreferences。每当付款活动完成时，将标记设置为1。

例如

int flag = entry.getInt("flag",0);
if(flag==0)
{
// Payment alert
// Payment finished
// editor.putInt("flag", ++flag);
// editor.commit();
}
else 
{
//Don't display the dialog
}

以这种方式，当用户完成付款时，将标志设置为1。
