1.AddContactsActivity类

package .demo.pr3;

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

import .demo.pr3.datax.ContactsTable; import .demo.pr3.datax.User; /*增加记录操作界面*/

public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.edit);

setTitle(\添加联系人\

//从已设置的页面布局查找对应的控件

nameEditText=(EditText)findViewById(R.id.name); mobileEditText=(EditText)findViewById(R.id.mobile); danweiEditText=(EditText)findViewById(R.id.danwei); qqEditText=(EditText)findViewById(R.id.qq);

addressEditText=(EditText)findViewById(R.id.address); }

/*创建菜单 */ public boolean onCreateOptionsMenu(Menu menu) { menu.add(Menu.NONE,1, Menu.NONE, \保存\ menu.add(Menu.NONE,2, Menu.NONE, \返回\ return super.onCreateOptionsMenu(menu); }

/* 菜单事件*/ public boolean onOptionsItemSelected(MenuItem item){ // TODO Auto-generated method stub

switch (item.getItemId()) {

case 1://保存 if(!nameEditText.getText().toString().equals(\ { User user=new User(); user.setName(nameEditText.getText().toString()); user.setMoblie(mobileEditText.getText().toString()); user.setDanwei(danweiEditText.getText().toString()); user.setQq(qqEditText.getText().toString()); user.setAddress(addressEditText.getText().toString()); ContactsTable ct= new ContactsTable(AddContactsActivity.this); if(ct.addData(user)) {

Toast.makeText(AddContactsActivity.this, \添加成功！\ Toast.LENGTH_SHORT).show(); finish(); }else { Toast.makeText(AddContactsActivity.this, \添加失败！\ Toast.LENGTH_SHORT).show(); } }else {

2. ContactsMessageActivity类

package .demo.pr3;

addressTextView=(TextView)findViewById(R.id.address);

//将要修改的联系人数据付值到用户界面显示 Bundle localBundle = getIntent().getExtras(); int id=localBundle.getInt(\

ContactsTable ct=new ContactsTable(this); user =ct.getUserByID(id);

nameTextView.setText(\ mobileTextView.setText(\ qqTextView.setText(\

danweiTextView.setText(\单位:\ addressTextView.setText(\地址:\ }

/*创建菜单*/ public boolean onCreateOptionsMenu(Menu menu) { menu.add(Menu.NONE, 1, Menu.NONE, \返回\ return super.onCreateOptionsMenu(menu); }

/* 菜单事件 */

public boolean onOptionsItemSelected(MenuItem item){ // TODO Auto-generated method stub switch (item.getItemId()) { case 1://返回 finish(); break; default: break; } return super.onOptionsItemSelected(item); } }

3. MyContactsActivity类

setTitle(\通讯录\

listView = (ListView) findViewById(R.id.listView); loadContacts(); }

/*加载联系人列表*/
