Accessandroid 共享地表视图的首选项
原标题:Access Android sharedPreferences from surfaceview

获取共享优惠的代码是

SharedPreferences settings = getSharedPreferences("MySettings", 0);
    float X = settings.getFloat("myFloat", 0);

但“ 强” 只在活动范围内有效 。

我怎么才能从别的地方进入呢?

单顿是一个好主意吗?我该如何设置和访问这个单顿。

我只想储存4个浮标,这本来会很棒!但没有任何东西是直接向前的:

是否对地表视图有“获取Context ()” 方法?

getContext().getSharedPreference();

如果这不起作用,你可以在启动时用单吨装上这些罐子,因为其中只有4个。

public class ClassicSingleton {

   public float float1;
   public float float2;
   public float float3;
   public float float4;

   private static ClassicSingleton instance = null;
   protected ClassicSingleton() {
      // Exists only to defeat instantiation.
   }
   public static ClassicSingleton getInstance() {
      if(instance == null) {
         instance = new ClassicSingleton();
      }
      return instance;
   }
}
