android实现左右滑动界面

首先要说的是，界面滑动，就需要多个view来进行切换，实际上可以用一个ArrayList<View> pageViews来保存这些view的信息，然后进行切换

LayoutInflater inflater = getLayoutInflater();
		pageViews = new ArrayList<View>();
		pageViews.add(inflater.inflate(R.layout.item01, null));
		pageViews.add(inflater.inflate(R.layout.item02, null));
		pageViews.add(inflater.inflate(R.layout.item03, null));

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" >

    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <ImageView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/feature_guide_0" >
        </ImageView>
    </LinearLayout>

</LinearLayout>

这里不得不说必须定义一个class GuidPageChangeListener 继承 OnPageChangeListener的接口来实现view之间的切换

	public void onPageSelected(int arg0) {
			// TODO Auto-generated method stub

			for (int i = 0; i < imageViews.length; i++) {
				imageViews[arg0]
						.setBackgroundResource(R.drawable.page_indicator_focused);
				if (arg0 != i) {
					imageViews[i]
							.setBackgroundResource(R.drawable.page_indicator);
				}
			}
		}

class GuidPageAdapter extends PagerAdapter 

主要引用的方法如下

class GuidPageAdapter extends PagerAdapter {

		@Override
		public int getCount() {
			// TODO Auto-generated method stub
			return pageViews.size();
		}

		@Override
		public boolean isViewFromObject(View arg0, Object arg1) {
			// TODO Auto-generated method stub
			return arg0 == arg1;
		}

		@Override
		public void destroyItem(View arg0, int arg1, Object arg2) {
			// TODO Auto-generated method stub
			((ViewPager) arg0).removeView(pageViews.get(arg1));
		}

		@Override
		public Object instantiateItem(View arg0, int arg1) {
			// TODO Auto-generated method stub
			((ViewPager) arg0).addView(pageViews.get(arg1));
			return pageViews.get(arg1);
		}
	}
