android中listview的超簡單運用

listview就是列表啦，一下代碼是listview的簡單運用。

首先是xml文件

<?xml version="1.0" encoding="utf-8"?>
<ListView android:id="@+id/listView1" android:layout_width="fill_parent"
	android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"></ListView>

其次是一個java文件

package com.android;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class FortestActivity extends Activity {
	private ListView list;
	String[] name = new String[] { "Java", "C++", "C", "C#", "VB", "XML",
			".NET", "J#" };

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		list = (ListView) findViewById(R.id.listView1);
		// 適配器
		ArrayAdapter<String> array = new ArrayAdapter<String>(this,
				android.R.layout.simple_list_item_multiple_choice, name);
		// 向列表添加數據
		list.setAdapter(array);
		// 一定要記得設置選擇模式，要不然點擊條目就沒有反應了撒。
		list.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
		// 設置監聽，這裏有好幾種的監聽方式，根據自身需要選擇。
		list.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				String show = (String) list.getItemAtPosition(arg2);
				Toast.makeText(FortestActivity.this, show + "被選擇",
						Toast.LENGTH_SHORT).show();
			}
		});

	}
}
