如何用ViewPager实现图片的切换
@Override
public Object instantiateItem(View container, int position) {
ImageView iv = new ImageView(mContext);
try
{
String path = mPaths.get(position);
Bitmap bm = BitmapFactory.decodeFile(path);
iv.setImageBitmap(bm);
}
catch(Exception e)
{
e.printStackTrace();
}
catch(OutOfMemoryError e)
{
e.printStackTrace();
}
((ViewPager)container).addView(iv, 0);
return iv;
}
