main.xml代碼如下：

<?xml version="1.0" encoding="utf-8"?>
<ScrollView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/myscroll"
    >
<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:id="@+id/mylinear" >
 
</LinearLayout>
</ScrollView>

.java代碼如下：

package org.lxh.demo;
 
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.DialogInterface;
import android.os.Bundle;

public class Hello extends Activity {
	String str[] = { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", };
 
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState); // 生命週期方法
		super.setContentView(R.layout.main); // 設置要使用的佈局管理器
		LinearLayout linear = (LinearLayout) super.findViewById(R.id.mylinear);//取得組件
		LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
				ViewGroup.LayoutParams.FILL_PARENT,
				ViewGroup.LayoutParams.WRAP_CONTENT);//定義按鈕的佈局參數
		for(int i=0;i<this.str.length;i++){
			Button btn=new Button(this);//創建按鈕組件
			btn.setText(this.str[i]);//設置文本
			linear.addView(btn,param);//增加組件
			
		}
 
	}
}
