android继承ListActivity实现列表ListView功能
解决方法：
1、layout目录下新建main.xml文件，内容：
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp"
android:textColor="#60c"
android:textSize="16sp" >
</TextView>
2、在string.xml的<resources>标签之间添加
<string-array name="countries_array">
<item>American</item>
<item>China</item>
</string-array>
3、MainActivity.java内容：
package com.example.ff;
import java.util.Calendar;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.ListActivity;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.graphics.Color;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.Menu;
import android.view.MenuItem;
import android.view.SubMenu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import android.widget.TimePicker;
import android.widget.Toast;
