2.代码实现

 public class MainActivity extends Activity {     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
     }     public void get(View v){
         EditText et_name = (EditText) findViewById(R.id.et_name);
         EditText et_pass = (EditText) findViewById(R.id.et_pass);         final String name = et_name.getText().toString();
         final String pass = et_pass.getText().toString();
         String url = "http://192.168.13.13/Web/servlet/CheckLogin?name=" + URLEncoder.encode(name) + "&pass=" + pass;
         //创建异步httpclient
         AsyncHttpClient ahc = new AsyncHttpClient();         //发送get请求提交数据
         ahc.get(url, new MyResponseHandler());
     }     public void post(View v){
         EditText et_name = (EditText) findViewById(R.id.et_name);
         EditText et_pass = (EditText) findViewById(R.id.et_pass);         final String name = et_name.getText().toString();
         final String pass = et_pass.getText().toString();
         String url = "http://192.168.13.13/Web/servlet/CheckLogin";         //创建异步httpclient
         AsyncHttpClient ahc = new AsyncHttpClient();         //发送post请求提交数据
         //把要提交的数据封装至RequestParams对象
         RequestParams params = new RequestParams();
         params.add("name", name);
         params.add("pass", pass);
         ahc.post(url, params, new MyResponseHandler());
     }     class MyResponseHandler extends AsyncHttpResponseHandler{         //请求服务器成功时，此方法调用
         @Override
         public void onSuccess(int statusCode, Header[] headers,
                 byte[] responseBody) {
             Toast.makeText(MainActivity.this, new String(responseBody), 0).show();         }         //请求失败此方法调用
         @Override
         public void onFailure(int statusCode, Header[] headers,
                 byte[] responseBody, Throwable error) {
             Toast.makeText(MainActivity.this, "请求失败", 0).show();         }     } }
