基于Android 4.2 SDK
布局文件如下：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/root" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" ></RelativeLayout>
Java源代码如下：
package com.example.image_display_demo;import android.app.Activity;import android.os.Bundle;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.ImageView;import android.widget.RelativeLayout;public class MainActivity extends Activity { int[] images = new int[]{ R.drawable.dff1, R.drawable.dff2, R.drawable.dff3, R.drawable.dff4, R.drawable.dff5, R.drawable.dff6, }; int currentImage = 0; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //获取RelativeLayout布局容器 RelativeLayout layout = (RelativeLayout)findViewById(R.id.root); //程序创建ImageView组件 final ImageView image = new ImageView(this); //将ImageView组件添加到RelativeLayout布局容器中 layout.addView(image); //初始化时显示第一张图片 image.setImageResource(images[0]); image.setOnClickListener(new OnClickListener(){ @Override public void onClick(View v) { // TODO Auto-generated method stub image.setImageResource(images[++currentImage % images.length]); } }); } @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; }}
