android Gallery组件实现的iPhone图片滑动效果实例

实现的效果图,可左右滑动:

一、先在将Gallery标签放入：

代码如下:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello"
    />
<Gallery
    android:id="@+id/gallery"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
/>
</LinearLayout>

二、Gallery 需要用Adapter来填充，先从BaseAdapter中派生一个ImageAdapter出来

代码如下:

public class ImageAdapter extends BaseAdapter
{
    private Context context;
    private int[] MyImageIDs =
    { R.drawable.icon, R.drawable.carlogo_52design_09,
            R.drawable.carlogo_52design_13, R.drawable.carlogo_52design_19,
            R.drawable.carlogo_52design_24, R.drawable.carlogo_52design_27,
            R.drawable.carlogo_52design_29, R.drawable.carlogo_52design_31,
            R.drawable.carlogo_52design_34, R.drawable.carlogo_52design_36 };
    public ImageAdapter(Context context)
    {
        // TODO Auto-generated constructor stub
        this.context = context;
    }
    @Override
    public int getCount()
    {
        // TODO Auto-generated method stub
        return MyImageIDs.length;
    }
    @Override
    public Object getItem(int arg0)
    {
        // TODO Auto-generated method stub
        return arg0;
    }
    @Override
    public long getItemId(int position)
    {
        // TODO Auto-generated method stub
        return position;
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        // TODO Auto-generated method stub
        ImageView i = new ImageView(this.context);
        i.setImageResource(this.MyImageIDs[position]);
        i.setScaleType(ImageView.ScaleType.FIT_XY);
        i.setLayoutParams(new Gallery.LayoutParams(120, 120));
        return i;
    }
}
