ActionBar
	//设置顶部背景

	//添加自定义视图
	actionBar.setDisplayShowCustomEnabled(true);
	actionBar.setCustomView(R.layout.nemu1);
	//显示返回首页ICON

	actionBar.setHomeActionContentDescription("ccccccccccc");
	actionBar.setHomeAsUpIndicator(R.drawable.c);

	actionBar.setIcon(R.drawable.c);
	actionBar.setLogo(R.drawable.aa);
	//显示ICON 或LOGO
	actionBar.setDisplayShowHomeEnabled(true);
	//为真现实LOGO 假显示 ICON
	actionBar.setDisplayUseLogoEnabled(true);

FrameLayout 层叠显示

LinearLayout 线性排列

TableLayout TableRow 表格排列

GridLayout 格子

RelativeLayout 相对排列 只针对下级(一级)子元素有效
	//相对同级视图 (值:视图ID)
	layout_below 放到指定视图下面
	layout_above 放到指定视图上面
	layout_toLeftOf 放到指定视图左边
	layout_toRightOf 放到指定视图右边
	layout_alignTop	顶边与指定视图顶边对齐
	layout_alignBottom 低边与指定视图低边对齐
	layout_alignLeft 左边与指定视图左边对齐
	layout_alignRight 右边与指定视图右边对齐
	layout_alignBaseline 与指定视图基准线对齐 (如保持文字在同行)
	
	//相对父视图 (值:true false)
	layout_alignParentTop  顶边与其父视图的顶边对齐
	layout_alignParentBottom 底边与其父视图的底边对齐
	layout_alignParentLeft  左边与其父视图的左边对齐
	layout_alignParentRight  右边与其父视图的右边对齐
	layout_centerHorizontal  在父视图中水平居中
	layout_centerVertical 在父视图中垂直居中
	layout_centerInParent  在父视图中的中央
