public class MainActivity extends ActionBarActivity {    EditText et_name;    EditText et_password;    Button b_post;    Button b_get;    URL url;    HttpURLConnection conn;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        et_name = (EditText)findViewById(R.id.et_name);        et_password = (EditText)findViewById(R.id.et_password);        b_get = (Button)findViewById(R.id.b_get);        b_post = (Button)findViewById(R.id.b_post);    }    public void clik(final View view){        new Thread(){            @Override            public void run() {                super.run();                String <span style="font-family:System;">name</span> = et_name.getText().toString();                String password = et_password.getText().toString();                if (name.isEmpty()|| password.isEmpty()){                    runOnUiThread(new Runnable() {                        @Override                        public void run() {                            Toast.makeText(MainActivity.this,"用户名或密码不能为空",Toast.LENGTH_SHORT).show();                        }                    });                    return;                }                final String s;                if (view.getId() == R.id.b_get){                    s= d<span style="font-family:System;">oGet(name ,password);</span>                }else {                    s= do<span style="font-family:System;">Post(name ,password);</span>                }                runOnUiThread(new Runnable() {                    @Override                    public void run() {                        Toast.makeText(MainActivity.this,s,Toast.LENGTH_SHORT).show();                    }                });            }        }.start();    }    public String doPost(String name,String password){        String u = "http://192.168.2.3:8080/Web/TestServlet";        String date = "name=" + name + "&password=" + password;        try {            url = new URL(u);            conn = (HttpURLConnection) url.openConnection();            conn.setRequestMethod("POST");            conn.setConnectTimeout(5000);            conn.setDoOutput(true);            conn.setDoInput(true);            PrintWriter pw = new PrintWriter(conn.getOutputStream());            pw.print(date);            pw.flush();            int code = conn.getResponseCode();            System.out.println(code);            if (code == 200){                InputStream is = conn.getInputStream();                String s = new BufferedReader(new InputStreamReader(is)).readLine();                System.out.println(s);                return s;            }else{                return "连接失败...";            }        } catch (Exception e) {            e.printStackTrace();            return "连接失败...";        }    }    public String doGet(String name,String password){        String u = "http://192.168.2.3:8080/Web/<span style="font-family: Arial, Helvetica, sans-serif;">TestServlet</span>";        String date = "?name=" + name + "&password=" + password;        try {            url = new URL(u + date);            conn = (HttpURLConnection) url.openConnection();            conn.setRequestMethod("GET");            conn.setConnectTimeout(5000);            int code = conn.getResponseCode();            if (code == 200){                InputStream is = conn.getInputStream();                String s = new BufferedReader(new InputStreamReader(is)).readLine();                System.out.println(s);                return s;            }else{                return "连接失败...";            }        } catch (Exception e) {            e.printStackTrace();            return "连接失败...";        }    }}
