在android中将字符串数组的ArrayList从一个活动传递到另一个活动

Question

我想在Android中将字符串数组的ArrayList从一个活动传递到另一个活动.
我如何使用intent或bundle？请考虑intent.putStringArrayListExtra在这种情况下不起作用,因为它不适用于字符串数组.

Answer 1

不确定你的意思是"字符串数组的ArrayList"

如果您有字符串数组,请检查以下链接

在android活动之间传递字符串数组

http://docs.oracle.com/javase/7/docs/api/java/util/ArrayList.html

ArrayList实现 Serializable

你可以使用意图

    ArrayList<String> mylist = new ArrayList<String>();  
    Intent intent = new Intent(ActivityName.this, Second.class);
    intent.putStringArrayListExtra("key", mylist);
    startActivity(intent);

要检索

    Intent i = getIntent();  
    ArrayList<String> list = i.getStringArrayListExtra("key");

public Intent putStringArrayListExtra (String name, ArrayList<String> value)

将扩展数据添加到intent.名称必须包含包前缀,例如app com.android.contacts将使用"com.android.contacts.ShowAll"之类的名称.

参数

name    The name of the extra data, with package prefix.
value   The ArrayList data value.

返回

Returns the same Intent object, for chaining multiple calls into a single statement.

传递String数组的ArrayList

String[] people = {
        "Mike Strong",
        "Jennifer Anniston",
        "Tom Bennet",
        "Leander Paes",
        "Liam Nesson",
        "George Clooney",
        "Barack Obama",
        "Steve Jobs",
        "Larry Page",
        "Sergey Brin",
        "Steve Wozniak"
};
String[] people1 = {
        "raghu", 
        "hello"
};


ArrayList<String[]> list = new ArrayList<String[]>();
list.add(people);
list.add(people1);
Intent i = new Intent(MainActivity.this,SecondActivity.class);
i.putExtra("key", list);
startActivity(i); 

要检索

Intent in = getIntent();
ArrayList<String[]> list =(ArrayList<String[]>) in.getSerializableExtra("key");
for(int i=0;i<list.size();i++)
{
   String s[]= list.get(i);
   for(int iv=0;iv<s.length;iv++)
   Log.i("..............:",""+s[iv]);
}
