public static final int SYSTEM\_UI\_FLAG\_HIDE\_NAVIGATION = 0x00000002;

隐藏导航栏

属性：

android:paddingstart(paddingend)：左右对齐时使用。

左对齐时：paddingstart对应paddingleft；paddingend对应paddingright；右对齐时则刚好相反；

android:paddingStart="?android:attr/listPreferredItemPaddingStart"

android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"

public boolean isShown()

Returns

\- True if this view and all of its ancestors are VISIBL

也就是只有当view本身和它的所有先人们都是visible时，isShown（）才返回TRUE。

而平常我们调用if(view.getVisibility() == View.VISIBLE)只是对view本身而不对先人的可见性进行判断。

public boolean post (Runnable action)

Runnable 并不一定是新开一个线程，比如下面的调用方法就是运行在UI主线程中的：

Handler mHandler=new Handler();

mHandler.post(new Runnable()\{

@Override public void run()

\{ // TODO Auto-generated method stub

\});

我们可以通过调用handler的post方法，把Runnable对象（一般是Runnable的子类）传过去；handler会在looper中调用这个Runnable的Run方法执行。

Runnable是一个接口，不是一个线程，一般线程会实现Runnable。所以如果我们使用匿名内部类是运行在UI主线程的，如果我们使用实现这个Runnable接口的线程类，则是运行在对应线程的。

具体来说，这个函数的工作原理如下：

View.post(Runnable)方法。在post(Runnable action)方法里，View获得当前线程（即UI线程）的Handler，然后将action对象post到Handler里。在Handler里，它将传递过来的action对象包装成一个Message（Message的callback为action），然后将其投入UI线程的消息循环中。在Handler再次处理该Message时，有一条分支（未解释的那条）就是为它所设，直接调用runnable的run方法。而此时，已经路由到UI线程里，因此，我们可以毫无顾虑的来更新UI。

参数

keyCode   KeyEvent中用于表示按键被按下的识别码

event        按键操作中定义的KeyEvent对象

<com.test.view.MyView>

MyView mv = (MyView)View.inflate (context,R.layout.my\_view,null);

当加载完成xml后，就会执行那个方法。
