如何加载一个ListView具有多阵列 [英] How to load a ListView with a multiple array

问题描述

我想从以下数组加载我的ListView

I'm trying to load my ListView from the following array

static final String[][] Bookings = new String[][] {{"WC11", "John Smith"},{"WX11", "Terry Jones"}};

我尝试使用以下code，但Eclipse中不会接受它。

I'm try to use the following code but Eclipse wont accept it.

ListView bkgList = (ListView) findViewById(R.id.bkg_list);
setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, Bookings));

它说'构造ArrayAdapter（ListVActivity，INT的String [] []）是不明确的。如何将我的数组加载到我的ListView？

It says 'the constructor ArrayAdapter(ListVActivity, int, String[][]) is undefined'. How can I load my array into my ListView?

推荐答案

ArrayAdapter是一维数组和构造函数需要像的String []预定。

ArrayAdapter is for a 1-d Array and the constructor expects something like String[] bookings.

您可以做这样的事情。请记住，你需要重写预订的toString（），因为这是显示在TextView中。

You can do something like this. Keep in mind you would need to override toString() of Booking because that is what is displayed in the TextView.

class Booking {
    String type;
    String name;
    public Booking(String type, String name) {
        this.type = type;
        this.name = name;
    }
}

Booking[] Bookings = new Booking[2];
Bookings[0] = new Booking("WC11", "John Smith");
Bookings[1] = new Booking("WX11", "Terry Jones");

ListView bkgList = (ListView) findViewById(R.id.bkg_list);
setListAdapter(new ArrayAdapter<Booking>(this, R.layout.list_item, Bookings));

如果你想保持2-D阵列可以延长 BaseAdapter ，以使自定义BookingsAdapter。

If you want to keep the 2-d array you can extend BaseAdapter to make a custom BookingsAdapter.
