一、编写MainActivity.java

package com.hyzhou.getdemo;

import com.hyzhou.getdemo.service.LoginServer;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {

    private EditText et_username, et_password;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        et_username = (EditText) findViewById(R.id.et_username);
        et_password = (EditText) findViewById(R.id.et_password);
    }

    public void click(View view) {
        final String username = et_username.getText().toString().trim();
        final String password = et_password.getText().toString().trim();
        new Thread(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                final String result = LoginServer
                        .loginByPost(username, password);
                if (result != null) {
                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                            // TODO Auto-generated method stub
                            Toast.makeText(MainActivity.this, result, 0).show();
                        }
                    });
                } else {
                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                            // TODO Auto-generated method stub
                            Toast.makeText(MainActivity.this, "请求失败", 0).show();
                        }
                    });
                }
            }
        }).start();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}
