過時方法更改技巧：檢視原始碼，看原始碼的提示資訊

例如

   /**
     * Set a listener that will be invoked whenever the page changes or is incrementally
     * scrolled. See {@link OnPageChangeListener}.
     *
     * @param listener Listener to set
     *
     * @deprecated Use {@link #addOnPageChangeListener(OnPageChangeListener)}
     * and {@link #removeOnPageChangeListener(OnPageChangeListener)} instead
 
.
     */
    @Deprecated
    public void setOnPageChangeListener(OnPageChangeListener listener) {
        mOnPageChangeListener = listener;
    }

 mViewPager.addOnPageChangeListener(new MyOnPageChangeListener());
