Android:简单的图片浏览器

package com.example.mixview;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends Activity {

	// 定义一个访问图片的数组
	int[] images = new int[] { R.drawable.p1, R.drawable.p2, R.drawable.p3,
			R.drawable.p4, R.drawable.p5, R.drawable.p6 };

	int currentImg = 0;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		// 获取LinearLayout布局容器
		LinearLayout main = (LinearLayout) findViewById(R.id.root);
		// 创建ImageView组件
		final ImageView image = new ImageView(this);
		// 创建TextView
		final TextView text = new TextView(this);
		// 将ImageView组件添加到LinearLayout布局容器中
		main.addView(image);
		main.addView(text);
		text.setText("当前第1张图片");
		// 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
				if (currentImg >= 5) {
					currentImg = -1;
				}
				text.setText("当前第" + (2 + currentImg) + "张图片");
				image.setImageResource(images[++currentImg]);
			}
		});

	}

	@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;
	}
}
