Android 设计一个可单选，多选的Demo

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<String>(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<String>(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。

LZ搞点更有层次的吧，介个一般工程里根本用不到这么简单的。SimpleCursorAdapter加simple_list_item_multichoice再自定义的listitem layout，最后有个listener，这多有意义啊

如果不用android.R.layout.simple_list_item_multiple_choice
怎么实现？

暂时没有android.R.layout.simple_list_item_multiple_choice源码
