效果图:
res/layout/main.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/backgroud"
android:id="@+id/layout">
</LinearLayout>
在res/drawable/下放置四张图片(img01.jpg、img02.jpg、img03.jpg、img04.jpg)
MainActivity:
package com.example.test;
import android.app.Activity;
import android.os.Bundle;
import android.view.ViewGroup.LayoutParams;
import android.widget.ImageView;
import android.widget.LinearLayout;
public class MainActivity extends Activity {
private ImageView[] img=new ImageView[4];//声明一个ImageView组件的数组
private int[] imagePath=new int[]{ //声明并初始化一个保存访问图片的数组
R.drawable.img01, R.drawable.img02, R.drawable.img03, R.drawable.img04
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//获取XML文件中定义的线性布局管理器
LinearLayout linearLayout =(LinearLayout)findViewById(R.id.layout);
for (int i = 0; i < imagePath.length; i++) {
img[i]=new ImageView(this);//创建一个ImageView组件
img[i].setImageResource(imagePath[i]);//为ImageView组件指定要显示的图片
img[i].setPadding(5, 5, 5, 5);//设置ImageView的内边距
LayoutParams params=new LayoutParams(253,148);//设置图片宽度和高度
img[i].setLayoutParams(params);//为ImageView组件设置布局参数
linearLayout.addView(img[i]);//将ImageView组件添加到布局管理器中
}
}
}
