LayoutInflater.Factory 妙用

LayoutInflater.Factory 可以调试 布局，你把下面的代码放到
onCreate里面，然后再里面的下面的onCreateView里面加上断点，然后你就可以知道所有的view构造，所有的view的名字，不管是自定义还是系统的。
感觉挺不错的。

protected void setMenuBackGround() {        LayoutInflater layoutInflater = getLayoutInflater();        final LayoutInflater.Factory existingFactory = layoutInflater.getFactory();// use introspection to allow a new Factory to be set        try {            Field field = LayoutInflater.class.getDeclaredField("mFactorySet");            field.setAccessible(true);            field.setBoolean(layoutInflater, false);            getLayoutInflater().setFactory(new LayoutInflater.Factory() {                @Override                public View onCreateView(String name, final Context context, AttributeSet attrs) {                    if (name                            .equalsIgnoreCase("android.support.v7.internal.view.menu.ListMenuItemView")) {                        try {                            LayoutInflater inflater = (LayoutInflater) context   .getSystemService(Context.LAYOUT_INFLATER_SERVICE);                            final View view = inflater.createView(name,                                    null, attrs);                            new Handler().post(new Runnable() {                                public void run() {                                    ViewParent parent = view.getParent();                                    ((ViewGroup) parent).setBackgroundResource(R.color.test);//                                    view.setBackgroundResource(R.color.test);                                }                            });                            return view;                        } catch (InflateException e) {                            e.printStackTrace();                        } catch (ClassNotFoundException e) {                            e.printStackTrace();                        }                    }                    // do whatever you want with the null or non-null view                    // such as expanding 'IconMenuItemView' and changing its style                    // or anything else...                    // and return the view                    return null;                }            });        } catch (NoSuchFieldException e) {            // ...        } catch (IllegalArgumentException e) {            // ...        } catch (IllegalAccessException e) {            // ...        }    }

然后这个类也很强大，可以做很多事情，向下兼容。等等，替换东西等等。
