android解释：实例化，实现

/**
 * Instantiates a layout XML file into its corresponding {@link android.view.View}
 * objects. It is never used directly. Instead, use
 * {@link android.app.Activity#getLayoutInflater()} or
 * {@link Context#getSystemService} to retrieve a standard LayoutInflater instance
 * that is already hooked up to the current context and correctly configured
 * for the device you are running on.  For example:
 *
 * <pre>LayoutInflater inflater = (LayoutInflater)context.getSystemService
 *      (Context.LAYOUT_INFLATER_SERVICE);</pre>
 * 
 * <p>
 * To create a new LayoutInflater with an additional {@link Factory} for your
 * own views, you can use {@link #cloneInContext} to clone an existing
 * ViewFactory, and then call {@link #setFactory} on it to include your
 * Factory.
 * 
 * <p>
 * For performance reasons, view inflation relies heavily on pre-processing of
 * XML files that is done at build time. Therefore, it is not currently possible
 * to use LayoutInflater with an XmlPullParser over a plain XML file at runtime;
 * it only works with an XmlPullParser returned from a compiled resource
 * (R.<em>something</em> file.)
 * 
 * @see Context#getSystemService
