Android 使用HttpGet进行登录

public class HttpActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final EditText editText  = new EditText(this);
        Button button = new Button(this);
        button.setText("登录");
        button.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                httpGet(editText); 
            }

        });
    }

    private void httpGet(final EditText editText) {
        try {
            HttpClient httpClient = new DefaultHttpClient();
            String username = "tom";
            String password = "123";
            String uri = "http://www.baidu.com?username=" + URLEncoder.encode(username,"utf-8") + "&password="+ URLEncoder.encode(password,"utf-8");
            HttpGet httpGet = new HttpGet(uri);
            HttpResponse response = httpClient.execute(httpGet);
            if (response.getStatusLine().getStatusCode() == 200) {
                InputStream inputStream = response.getEntity().getContent();
                String result = NetUtils.parseStream(inputStream);
                editText.setText(result);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
