Adapter:

public class AdViewPagerAdapter extends PagerAdapter {private ArrayList<View> Views;private int[] drawables = {R.drawable.five,R.drawable.four,R.drawable.six};public AdViewPagerAdapter(ArrayList<View> views) {super();this.Views = views;}@Overridepublic int getCount() {return Views.size();}@Overridepublic boolean isViewFromObject(View arg0, Object arg1) {return arg0 == arg1;}@Overridepublic void destroyItem(View container, int position, Object object) {((ViewPager) container).removeView(Views.get(position));}@Overridepublic Object instantiateItem(View container, int position) {if (position >= Views.size() - 1) {int newPosition = position % Views.size();position = newPosition;}try {((ViewPager) container).addView(Views.get(position), 0);} catch (Exception e) {}return Views.get(position);}}

FileUtil:

public class FileUtil {/** * 创建目录 *  * @param dirName *            目录名字 * @return */public static File createSDDir(String dirName) {File dir = new File(dirName);dir.mkdirs();return dir;}/** * 创建文件 *  * @param fileName *            文件名字 * @return * @throws IOException */public static File createSDFile(String fileName) throws IOException {File file = new File(fileName);file.createNewFile();return file;}/** * 得到设备外部存储目录 */public static final String SDPath = android.os.Environment.getExternalStorageDirectory().getPath() + "/";/** * 保存文件到SD卡 *  * @param bitmap *            图片对象 * @param file *            保存文件的路径 */public static void copyFile(Bitmap bitmap, File file) {try {BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file));bitmap.compress(Bitmap.CompressFormat.JPEG, 80, bos);bos.flush();bos.close();} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}}
