Gallery实现图片滑动

1. 设计布局文件

<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" >

    <Gallery
        android:id="@+id/my_gallery"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"/>
    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        />
</RelativeLayout>

1. MainActivity.java实现图片的滑动

package com.example.gaojikongjian;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Gallery;
import android.widget.ImageView;
/***
 * 实现图片的滑动，如相册

public class MainActivity extends Activity {
	private Gallery gallery;
	//m 数据层
	int data[] = {R.drawable.b0,R.drawable.b1,R.drawable.b2,R.drawable.b3,R.drawable.b4,R.drawable.b5,R.drawable.b6};
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		//v
		gallery = (Gallery)findViewById(R.id.my_gallery);
		//c 控制层
		gallery.setAdapter(new BaseAdapter() {
			@Override
			public View getView(int position, View convertView, ViewGroup arg2) {
				ImageView im = new ImageView(MainActivity.this);
				im.setImageResource(data[position]);
				return im;
			}
			@Override
			public long getItemId(int position) {
				return position;
			}
			@Override
			public Object getItem(int position) {
				return data[position];
			}
			@Override
			public int getCount() {
				return data.length;
			}
		});
	}
}
