android 设计一个可单选，多选的demo -买球官网平台

android 提供了相当多的ui，在android.widget 的ui组件库，下面就让我们看看他是listview的用法吧。

下面的demo 是一个

package com.example.android.apis.view;
import android.app.listactivity;
import android.os.bundle;
import android.widget.arrayadapter;
import android.widget.listview;
/**
 * this example shows how to use choice mode on a list. this list is 
 * in choice_mode_single mode, which means the items behave like
 * checkboxes.
 */
public class list10 extends listactivity {
    @override
    public void oncreate(bundle savedinstancestate) {
        super.oncreate(savedinstancestate);
        setlistadapter(new arrayadapter(this,
                android.r.layout.simple_list_item_single_choice, genres));
        final listview listview = getlistview();
        listview.setitemscanfocus(false);
        listview.setchoicemode(listview.choice_mode_single);
    }
    private static final string[] genres = new string[] {
        "action", "adventure", "animation", "children", "comedy", "documentary", "drama",
        "foreign", "history", "independent", "romance", "sci-fi", "television", "thriller"
    };

上面是一个单选的list demo。

对于需要多选的话可以改变这些参数就ok了

setlistadapter(new arrayadapter(this,
                android.r.layout.simple_list_item_multiple_choice, genres));
        final listview listview = getlistview();
        listview.setitemscanfocus(false);
        listview.setchoicemode(listview.choice_mode_multiple);

很简单吧，android的开发确实很不错。
