利用简易Tomcat服务器结合MysqL实现Android手机注册与登录(客户_MySQL

package com.example.java4androidmysql;import java.io.IOException;import java.io.UnsupportedEncodingException;import java.util.ArrayList;import java.util.List;import org.apache.http.HttpResponse;import org.apache.http.HttpStatus;import org.apache.http.client.ClientProtocolException;import org.apache.http.client.HttpClient;import org.apache.http.client.entity.UrlEncodedFormEntity;import org.apache.http.client.methods.HttpPost;import org.apache.http.conn.params.ConnManagerParams;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.message.BasicNameValuePair;import org.apache.http.params.BasicHttpParams;import org.apache.http.params.HttpConnectionParams;import org.apache.http.params.HttpParams;import org.apache.http.protocol.HTTP;import org.apache.http.util.EntityUtils;import android.os.AsyncTask;import android.os.Bundle;import android.app.Activity;import android.content.Intent;import android.view.Menu;import android.view.View;import android.view.Window;import android.widget.Button;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {	public static final String URL = "http://192.168.2.1:8080/JavaRegisterMysql/login";	public static String res=""; public static String name = ""; public static String code = ""; public static String phone =" "; public static String chose="0";	Button connectButton=null;	Button registerButton=null;	EditText noteUser=null;	EditText notePassword=null;	@Override	protected void onCreate(Bundle savedInstanceState) {	super.onCreate(savedInstanceState);	requestWindowFeature(Window.FEATURE_NO_TITLE);	setContentView(R.layout.activity_main);	connectButton=(Button)findViewById(R.id.btnConnect);	registerButton=(Button)findViewById(R.id.btnRegister); noteUser=(EditText)findViewById(R.id.editUserName); notePassword=(EditText)findViewById(R.id.editPassword); //////注意类Class DriverManager Statement ResultSet connectButton.setOnClickListener(new View.OnClickListener() {	public void onClick(View v) {	 	 Toast.makeText(MainActivity.this, "正在登录", Toast.LENGTH_SHORT).show();	 name = noteUser.getText().toString().trim();	 code = notePassword.getText().toString().trim(); 	 chose="1";	 new SubmitAsyncTask().execute(URL);	 	 Toast.makeText(MainActivity.this, "res = "+res, Toast.LENGTH_SHORT).show();	 if(res.equals("2")){	 	Toast.makeText(MainActivity.this, "登录成功", Toast.LENGTH_SHORT).show();	 	//Intent intent=new Intent();	 	//intent.setClass(MainActivity.this, WriteNote.class);	 	//MainActivity.this.startActivity(intent);	 }else if(res.equals("1")){	 	Toast.makeText(MainActivity.this, "用户名或密码错误", Toast.LENGTH_SHORT).show();	 }else if(res.equals("3")){	 	Toast.makeText(MainActivity.this, "注册失败", Toast.LENGTH_SHORT).show();	 }else if(res.equals("4")){	 	Toast.makeText(MainActivity.this, "注册成功", Toast.LENGTH_SHORT).show();	 }else if(res.equals("-1")){	 	Toast.makeText(MainActivity.this, "网络异常", Toast.LENGTH_SHORT).show();	 }	}	}); noteUser.setText("ab"); notePassword.setText("123456"); 	registerButton.setOnClickListener(new View.OnClickListener() {	public void onClick(View v) {	 	Intent intent=new Intent();	intent.setClass(MainActivity.this, Register.class);	MainActivity.this.startActivity(intent);	 	}	});	 	}	@Override	public boolean onCreateOptionsMenu(Menu menu) {	// Inflate the menu; this adds items to the action bar if it is present.	getMenuInflater().inflate(R.menu.main, menu);	return true;	}	}

以上为手机主界面函数调用

package com.example.java4androidmysql;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.Window;import android.widget.Button;import android.widget.EditText;import android.widget.Toast;public class Register extends Activity{	public static final String URL = "http://192.168.2.1:8080/JavaRegisterMysql/login";	Button backButton=null;	Button registerButton=null;	EditText user=null;	EditText password=null;	EditText phone=null;	@Override	protected void onCreate(Bundle savedInstanceState) {	// TODO Auto-generated method stub	super.onCreate(savedInstanceState);	requestWindowFeature(Window.FEATURE_NO_TITLE);	setContentView(R.layout.register);	backButton=(Button)findViewById(R.id.btnBack);	registerButton=(Button)findViewById(R.id.btnRegister); user=(EditText)findViewById(R.id.editUserName); password=(EditText)findViewById(R.id.editPassword); phone=(EditText)findViewById(R.id.editPhone); //////注意类Class DriverManager Statement ResultSet registerButton.setOnClickListener(new View.OnClickListener() {	public void onClick(View v) {	 	 MainActivity.name = user.getText().toString().trim();	 MainActivity.code = password.getText().toString().trim();	 MainActivity.phone = phone.getText().toString().trim();	 MainActivity.chose="2";	 	 new SubmitAsyncTask().execute(URL);	 	 Toast.makeText(Register.this, "res = "+MainActivity.res, Toast.LENGTH_SHORT).show();	 if(MainActivity.res.equals("2")){	 	Toast.makeText(Register.this, "登录成功", Toast.LENGTH_SHORT).show();	 	//Intent intent=new Intent();	 	//intent.setClass(MainActivity.this, WriteNote.class);	 	//MainActivity.this.startActivity(intent);	 }else if(MainActivity.res.equals("1")){	 	Toast.makeText(Register.this, "用户名或密码错误", Toast.LENGTH_SHORT).show();	 }else if(MainActivity.res.equals("3")){	 	Toast.makeText(Register.this, "注册失败", Toast.LENGTH_SHORT).show();	 }else if(MainActivity.res.equals("4")){	 	Toast.makeText(Register.this, "注册成功", Toast.LENGTH_SHORT).show();	 }else if(MainActivity.res.equals("-1")){	 	Toast.makeText(Register.this, "网络异常", Toast.LENGTH_SHORT).show();	 }	 	}	}); user.setText("gjw"); password.setText("123"); phone.setText("13570236302");	}}

以上为注册界面

package com.example.java4androidmysql;import java.io.IOException;import java.io.UnsupportedEncodingException;import java.util.ArrayList;import java.util.List;import org.apache.http.HttpResponse;import org.apache.http.HttpStatus;import org.apache.http.client.ClientProtocolException;import org.apache.http.client.HttpClient;import org.apache.http.client.entity.UrlEncodedFormEntity;import org.apache.http.client.methods.HttpPost;import org.apache.http.conn.params.ConnManagerParams;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.message.BasicNameValuePair;import org.apache.http.params.BasicHttpParams;import org.apache.http.params.HttpConnectionParams;import org.apache.http.params.HttpParams;import org.apache.http.protocol.HTTP;import org.apache.http.util.EntityUtils;import android.os.AsyncTask;public class SubmitAsyncTask extends AsyncTask{ String info = ""; protected String doInBackground(String... params) { // TODO Auto-generated method stub String url = params[0]; String reps = ""; reps = doPost(url); return reps; } protected void onPostExecute(String result) { // TODO Auto-generated method stub MainActivity.res = result.trim(); super.onPostExecute(result); } /** * 用Post方式跟服务器传递数据 * @param url * @return */private String doPost(String url){ String responseStr = ""; try { 	//发送post类型请求 HttpPost httpRequest = new HttpPost(url); HttpParams params = new BasicHttpParams(); ConnManagerParams.setTimeout(params, 1000); //从连接池中获取连接的超时时间 HttpConnectionParams.setConnectionTimeout(params, 3000);//通过网络与服务器建立连接的超时时间 HttpConnectionParams.setSoTimeout(params, 5000);//读响应数据的超时时间 httpRequest.setParams(params); //下面开始跟服务器传递数据，使用BasicNameValuePair List paramsList = new ArrayList(); paramsList.add(new BasicNameValuePair("NAME", MainActivity.name)); paramsList.add(new BasicNameValuePair("CODE", MainActivity.code)); paramsList.add(new BasicNameValuePair("PHONE", MainActivity.phone)); paramsList.add(new BasicNameValuePair("CHOSE", MainActivity.chose)); UrlEncodedFormEntity mUrlEncodeFormEntity = new UrlEncodedFormEntity(paramsList, HTTP.UTF_8); httpRequest.setEntity(mUrlEncodeFormEntity); //////////////////////////////////////////////// HttpClient httpClient = new DefaultHttpClient(); HttpResponse httpResponse = httpClient.execute(httpRequest); final int ret = httpResponse.getStatusLine().getStatusCode(); if(ret == HttpStatus.SC_OK){ responseStr = EntityUtils.toString(httpResponse.getEntity(), HTTP.UTF_8); }else{ responseStr = "-1"; } } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return responseStr;	}}

以上为接口类，但写得可能有些不对（如返回变量那里是上次调用的），略忙，等再改一下。
