该示例展示了如何在Android应用中使用GET和POST方法发送请求。通过两个按钮分别触发GET和POST请求，并从EditText输入框获取用户名和密码进行网络交互。成功响应后会显示服务器返回的信息。

public class Main extends Activity { private Button btnGet; private Button btnPost; private EditText etName; private EditText etPwd; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); btnGet = (Button) findViewById(R.id.btnGet); btnPost = (Button) findViewById(R.id.btnPost); etName = (EditText) findViewById(R.id.etName); etPwd = (EditText) findViewById(R.id.etPassword); btnGet.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { HttpGet request = new HttpGet( "http://www.ineeke.com/android/android.php?name=" + etName.getText().toString() + "&pwd=" + etPwd.getText().toString()); try { HttpResponse response = new DefaultHttpClient() .execute(request); if (response.getStatusLine().getStatusCode() == 200) { String result = EntityUtils.toString(response .getEntity()); Toast.makeText(Main.this, result, Toast.LENGTH_LONG) .show(); } } catch (Exception e) { Toast.makeText(Main.this, e.getMessage().toString(), Toast.LENGTH_LONG).show(); e.printStackTrace(); } } }); btnPost.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { HttpPost request = new HttpPost( "http://www.ineeke.com/android/android.php"); List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("name", etName.getText() .toString())); params.add(new BasicNameValuePair("pwd", etPwd.getText() .toString())); try { request.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8)); HttpResponse response = new DefaultHttpClient() .execute(request); if (response.getStatusLine().getStatusCode() == 200) { String result = EntityUtils.toString(response .getEntity()); Toast.makeText(Main.this, result, Toast.LENGTH_LONG) .show(); } } catch (Exception e) { Toast.makeText(Main.this, e.getMessage().toString(), Toast.LENGTH_LONG).show(); e.printStackTrace(); } } }); } }
