有什么优势RelativeLayout超过LinearLayoutandroid系统？对于一个特定的设计,你更喜欢哪一个,背后的原因是什么？

它(RelativeLayout)是否与HTML相似或类似<div>？

可能重复:
String,StringBuffer和StringBuilder

我们知道这String是不可变的StringBuffer/ StringBuilder可变的.但有时我们会混淆在代码中使用什么.. String或StringBuffer/StringBuilder ?? 实际上,我们使用的最大代码/快速代码String比StringBuffer/ 更喜欢StringBuilder.

这个问题是为了解决这个问题,如果你有任何想法和正当理由,请回复.

我想在logcat中打印InputStream(用于测试/稍后我将使用它),我目前的代码如下.

        @Override
        protected Void doInBackground(Void... params) {

            try {

                InputStream in = null;
                int response = -1;

                URL url = new URL(
                        "http://any-website.com/search/users/sports+persons");
                URLConnection conn = null;
                HttpURLConnection httpConn = null;
                conn = url.openConnection();

                if (!(conn instanceof HttpURLConnection))
                    throw new IOException("Not an HTTP connection");

                httpConn = (HttpURLConnection) conn;
                httpConn.setAllowUserInteraction(false);
                httpConn.setInstanceFollowRedirects(true);
                httpConn.setRequestMethod("GET");
                httpConn.connect();

                response = httpConn.getResponseCode();
                if (response == HttpURLConnection.HTTP_OK) {
                    in = httpConn.getInputStream();
                }

                if (in != null) {
                    Log.e(TAG, ">>>>>PRINTING<<<<<");
                    Log.e(TAG, in.toString());
                   // TODO: print 'in' from here
                } …
