		//Step0: 得到一个全屏视图:
		this.requestWindowFeature(Window.FEATURE_NO_TITLE);
		getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
				WindowManager.LayoutParams.FLAG_FULLSCREEN);
		
		//Step1: 得到屏幕分辨率
		Display display = getWindowManager().getDefaultDisplay(); 
		int width = display.getWidth();
		int height = display.getHeight();
		
		//Step2: 创建所需的标记列表:
		//注意: 所有标签必须有独特的文本字段
		//如果没有,只有第一次出现将被添加,其余的将被忽略
		List<Tag> myTagList= createTags();
		
		//Step3: 创建TagCloudview MainActivity并将它设置为内容
		mTagCloudView = new TagCloudView(this, width, height, myTagList ); //通过当前上下文 
		setContentView(mTagCloudView);
		mTagCloudView.requestFocus();
		mTagCloudView.setFocusableInTouchMode(true);
		
		//Step4: (可选择) 添加一个新的标签,整个3 d TagCloud重置
		//您还可以添加个人标签:
		//mTagCloudView.addTag(new Tag("AAA", 5, "http://www.aaa.com"));
		// .... (可以添加其他几个tasg相似 )
		//如果旧标签不动indivual标记将被放置在前面的 因此,在添加许多个人标签 后，TagCloud代码可能不是均匀分布的。reset()re-positions所有标签
		//mTagCloudView.reset();
		
		//Step5: (可选择) 替换之前的标签之一,用一个新的标签，你一定要创建一个新的标签并且把他们放一起通过现有的文本标签，你想取代的
		//Tag newTag=new Tag("Illinois", 9, "http://www.illinois.com");
		//为了用Google去替代以前的标签
		//boolean result=mTagCloudView.Replace(newTag, "google");
		//如果Google被发现并且替换了将返回true，否则为false
