inflate, findViewById与setContentView的区别与联系

protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_news_content);viewFlipperNewsUi = (ViewFlipper) findViewById(R.id.viewflipper_news_ui); inflater = getLayoutInflater();View rLNewsUi = inflater.inflate(R.layout.news_body, null);viewFlipperNewsUi.addView(rLNewsUi);}

1、inflate是用来找layout下布局文件，并实例化；而findViewById是找布局文件下的具体widget。

2、setContentView()一旦调用, layout就会立刻显示UI；而inflate只会把Layout形成一个以view类实现成的对象，有需要时再用setContentView(view)显示出来。
