Android--ListView和ArrayAdapter例子

File:MainActivity.java

package com.jiangge.arrayadapterdemo;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivity extends Activity {

	private static  String City[] = {"北京", "上海", "天津", "河北", "山东", "山西", "河南"};
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		ListView listView = (ListView) findViewById(R.id.list_view);
		listView.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item, R.id.text_view, City));
	}

}

注：listView.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item, R.id.text_view, City)); 每个参数的意义
