android Gallery组件实现的iPhone图片滑动效果实例

前端技术 2023/09/08 Android

实现的效果图,可左右滑动:

一、先在将Gallery标签放入:

复制代码 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
复制代码 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;
    }
}
