实例化inflate进来的组件与include进来的组件

		mInflater = getLayoutInflater();

		layout1 = mInflater.inflate(R.layout.personalcenter_1, null);

		ib_friends = (ImageButton)layout1.findViewById(R.id.ib_friends);

获取include中的布局里的组件

<include android:id="@+id/main1" layout="@layout/sublayout" /> 

先find include布局作为view，然后find include里的组件

View subLayout1 = (View)findViewById(R.id.main1);  
        Button myButton_main1 = (Button)subLayout1.findViewById(R.id.mybutton);
