Android : What is the difference between View. 膨胀和 getLayoutInflater().膨胀？

Question

什么是真正的区别:

return context.getLayoutInflater().inflate(R.layout.my_layout, null);

Inflate a new view hierarchy from the specified xml resource.

和

return View.inflate(context, R.layout.my_layout, null);

Inflate a view from an XML resource. This convenience method wraps the LayoutInflater class, which provides a full range of options for view inflation.

Answer 1

两者是一样的。第二个版本只是完成任务的一种方便而简短的方法。如果您查看 View.inflate() 方法的源代码，您会发现:

 /**
     * Inflate a view from an XML resource.  This convenience method wraps the {@link
     * LayoutInflater} class, which provides a full range of options for view inflation.
     *
     * @param context The Context object for your activity or application.
     * @param resource The resource ID to inflate
     * @param root A view group that will be the parent.  Used to properly inflate the
     * layout_* parameters.
     * @see LayoutInflater
     */
    public static View inflate(Context context, int resource, ViewGroup root) {
        LayoutInflater factory = LayoutInflater.from(context);
        return factory.inflate(resource, root);
    }

实际上在后端做同样的工作，你提到的第一种方法。
