每天进步一点点（今天最大的收获是懂了这么多eclipse的快捷键，感觉好方便啊）

下面是一个简单的ListView，前面好像写了一篇类似的文章，只不过前面只是略懂一二，虽然现在也是略懂二三而已。

package com.example.mylistview;

import java.util.Random;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;

public class MainActivity extends Activity {
	private ListView lv;
	private MyAdapter adapter;
	private Random rd;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		lv = (ListView) findViewById(R.id.lv);

		rd = new Random();
		adapter = new MyAdapter();
		lv.setAdapter(adapter);

	}

	private class MyAdapter extends BaseAdapter {

		@Override
		public int getCount() {
			// TODO Auto-generated method stub
			return 50;
		}

		@Override
		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return null;
		}

		@Override
		public long getItemId(int position) {
			// TODO Auto-generated method stub
			return 0;
		}

		@Override
		public View getView(int position, View convertView, ViewGroup parent) {
			// TODO Auto-generated method stub
			TextView tv = new TextView(getApplicationContext());
			tv.setText(String.valueOf(rd.nextInt(5000)));
			return tv;
		}

	}

}

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/ll"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <ListView
        android:id="@+id/lv"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </ListView>

</LinearLayout>

如果用inflate的话，getView函数可以这样写（不过这之前请写好list_item.xml）

@Override
		public View getView(int position, View convertView, ViewGroup parent) {
			// TODO Auto-generated method stub
			//TextView tv = new TextView(getApplicationContext());
			//tv.setText(String.valueOf(rd.nextInt(5000)));
			//return tv;
			View view = View.inflate(MainActivity.this, R.layout.list_item, null);
			TextView num = (TextView) view.findViewById(R.id.item_num);
			num.setText(rd.nextInt(5000)+"");
			
			return view;
		}
