本文介绍了使用HTTP GET和POST方法进行远程数据交互的过程，并详细解释了如何通过Android客户端发送请求并接收响应。

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();
				}
			}
		});
	}
}
