最佳回答

你们可以创造自己的单州阶级,你们的活动和其他阶层都可以随时进入。 你们必须小心谨慎,因为它确实增加了一层全球变数(人们往往不喜欢),而是发挥作用。

public class MyBoolean{

   private static final MyBoolean instance = new MyBoolean();

   private boolean boolValue = false;

   private MyBoolean(){}

   public static MyBoolean getInstance(){
      return instance;
   }

   public boolean getValue(){
      return boolValue;
   }

   public void setValue(boolean newValue){
      boolValue = newValue;
   }
}

电话:MyBoolean.getInstance(,你可以采用与你整个方案结合的方法。

活动途径:

Intent i = new Intent(getBaseContext(), NameOfActivity.class);
i.putExtra("my_boolean_key", myBooleanVariable);
startActivity(i)

3. 第二次活动回顾:

Bundle bundle = getIntent().getExtras();
boolean myBooleanVariable = bundle.getBoolean("my_boolean_key");
