首先執行步驟如下

1.viewPager需要無限輪播
2.小圓點的個數
3.imageLoader載入圖片
4.handler自動輪播
一.在佈局檔案上
<android.support.v4.view.ViewPager android:layout_height="200dp" android:layout_width="match_parent" android:id="@+id/view_pager"> </android.support.v4.view.ViewPager>

<LinearLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/linear_layout" android:orientation="horizontal" android:layout_marginBottom="20dp" android:layout_centerHorizontal="true" android:layout_alignBottom="@+id/view_pager"> </LinearLayout>
