一、界面控制

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<Button 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="饼图"  android:onClick="bing"
    />
    
    <Button 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="柱状图"  android:onClick="zhu"
    />
    
    <Button 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="折线图"   android:onClick="zhexian"
    />
</LinearLayout>

二、主程序MainAct

package com.lee;

import java.util.ArrayList;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

import com.lee.modle.Information;
/**
 * 
 * @author 
 * Patata丶
 * http://www.weibo.com/totome
 *
 */

public class MainAct extends Activity {

	ArrayList<Information>informations;
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        
        informations = new ArrayList<Information>();
        //数据假设  初始化
        informations.add(new Information("福建", "7434832", "人"));
        informations.add(new Information("广东", "9434832", "人"));
        informations.add(new Information("浙江", "5434832", "人"));
        informations.add(new Information("江苏", "7436832", "人"));
        informations.add(new Information("香港", "7464832", "人"));
        informations.add(new Information("陕西", "6464832", "人"));
        informations.add(new Information("上海", "4534832", "人"));
        informations.add(new Information("北京", "9435832", "人"));
         
       
    }
    
    
    
    /**
     * 按键监听
     */
    public void bing(View view)
    {
    	Intent intent = new Intent(this, Pie_char.class);
		intent.putExtra("informations", informations);
		intent.putExtra("title", "人口数据");
		startActivity(intent);
    }
    
    public void zhu(View view)
    {
    	Intent intent = new Intent(this, Stacked.class);
		intent.putExtra("informations", informations);
		intent.putExtra("title", "人口数据");
		startActivity(intent);
    }
    
    public void zhexian(View view)
    {
    	Intent intent = new Intent(this, Zhexian.class);
		intent.putExtra("informations", informations);
		intent.putExtra("title", "人口数据");
		startActivity(intent);
    }               
}

三、操作类Information

package com.lee.modle;

import java.io.Serializable;
public class Information implements Serializable
{
	public String weidu; //名称

	public String dulian1; //数据

	public String bfb;  //百分比

	public String dw;  //单位
	public Information(String weidu, String dulian1, String dw)
	{
		super();

		this.dw = dw;
	}

	public Information ()
	{
		
	}
	
}
