在android中顯示連接的簡單代碼php代碼地址：http://kardgar.gigfa.com/toosab/connect.php ?i=1我還添加了 use-permission android:name="android.permission.INTERNET"和MainActivity.javapublic class MainActivity extends AppCompatActivity {public static String res = "";@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    Button btn = (Button) findViewById(R.id.button);    new getcount("http://kardgar.gigfa.com/toosab/connect.php").execute();    btn.setOnClickListener(new View.OnClickListener() {        @Override        public void onClick(View v) {            Toast.makeText(getApplicationContext() ,res ,Toast.LENGTH_LONG).show();        }    });}}和 getcount.javapublic class getcount extends AsyncTask{private String Link="";public getcount(String link ){    Link=link;}@Overrideprotected String doInBackground(Object... arg0) {    try{        String data = "";        URL mylink=new URL(Link);        URLConnection connect=mylink.openConnection();        connect.setDoOutput(true);        OutputStreamWriter wr = new OutputStreamWriter(connect.getOutputStream());        wr.write(data);        wr.flush();          BufferedReader reader=new BufferedReader(new InputStreamReader(connect.getInputStream()));        StringBuilder sb=new StringBuilder();        String line=null;        while((line=reader.readLine()) !=null){            sb.append(line);        }        MainActivity.res = sb.toString();    }catch(Exception ignored){    }    return "";}}當我運行這段代碼時，我得到了其他東西
