如何在不启动的情况下将数组列表从一个活动传递到另一个活动 [英] How to pass an array list from one activity to another without starting it

问题描述

我有一个包含数组列表的活动

I have an activity which has an array list

ArrayList<String> array = new ArrayList<String>(); 

我希望在单击保存"按钮时将此数组列表传递给另一个活动，但我不希望该活动开始...

i want this array list to be passed to another activity when a Save button is clicked, but i don't want that activity to start...

通常此代码有助于启动活动

Usually this code helps in starting an activity

 public void onClick(View v) {
 if (v==Save)
            {
                Bundle bundle = new Bundle();
                bundle.putStringArrayList("DONE", activeURL);
                Intent myIntent = new Intent(Reader2.this, Aggregator.class);
                myIntent.putExtra("reader2", activeURL);
                startActivity(intent);

                }
}

但我只想传递数组并开始另一个活动.你能帮我么 ?提前致谢.

but i just want to pass the array and start another activity. Can you please help me ? Thanks in advance.

推荐答案

您可以像这样将 ArrayList 声明为静态的，

You can declare you ArrayList as a static one like this,

public static ArrayList<String> array = new ArrayList<String>(); 

通过这样做，您可以通过以下方式从任何地方访问您的 ArrayList

By doing this you can access your ArrayList from anywhere by

activity_name.array;

其中 activity_name 是您在其中声明静态 ArrayList 的活动或类

where activity_name is the activity or class in which you declare the static ArrayList
