列1：

显示一定数量的图片

1.将图片导入到res/drawable文件下
2.xml代码
这里写图片描述

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".MainActivity" >    <ScrollView        android:id="@+id/scrollView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:layout_alignParentLeft="true"        android:layout_alignParentRight="true"        android:layout_alignParentTop="true" >        <LinearLayout            android:id="@+id/line"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical" >        </LinearLayout>    </ScrollView></RelativeLayout>

3.java代码

package com.example.android010;import android.os.Bundle;import android.app.Activity;import android.graphics.drawable.Drawable;import android.view.Menu;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.ScrollView;public class MainActivity extends Activity {//  private ScrollView scrollview;    private LinearLayout layout;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        layout=(LinearLayout)findViewById(R.id.line);        for(int i=0;i<10;i++){            ImageView image=new ImageView(this);//创建`ImageView对象            //获取图片地址            Drawable drawable=getResources().getDrawable(R.drawable.d3);            image.setImageDrawable(drawable);            //添加到listview中            layout.addView(image,i);        }    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }}
