最近写数据库，我就自己写了个带密码的个人通讯录，感觉sqlite特别好用，和mysql，sqlserver都一样，真是简单的关系型数据库，注意：开启数据库，cursor后一定要记得关闭close（）掉，避免浪费资源。另外adapter的notifyDataSetChanged（）这个方法也特别好用，就是数据库更新的时候，调用一下，baseAdapter中的getview就会重新加载一遍，这样界面就会更新数据，而不用onCreate（）方法来更新，另外可以把notifyDataSetChanged（）方法写在onResume（）方法中，这样在两个activity跳转后按back键也可以达到刷新界面的效果！

想要源码的可以留言，有问题可以留言，同时也欢迎指正我的纰漏；

程序启动后输入密码的界面：第一次启动程序和点击修改密码界面：

点击确定，进入联系人列表界面：点击menu菜单，有两个菜单键：

单击每一个列表进入修改界面：长按每一个联系人弹dialog删除记录：

下面看代码：

在com.cn.daming包下的类：

1、Login.java 程序的入口类

package com.cn.daming; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.Toast; import com.cn.daming.databases.DBOpenHelper; public class Login extends Activity { private DBOpenHelper db; private EditText et; private Button login_button; private String password; @Override protected void onCreate(Bundle bundle) { super.onCreate(bundle); db = new DBOpenHelper(this); password = db.getPwd(); db.close(); if(password.equals("")){ Intent intent = new Intent(Login.this,PasswordManage.class); startActivity(intent); finish(); return; } setContentView(R.layout.login); et = (EditText)findViewById(R.id.login_password); login_button = (Button)findViewById(R.id.note_login); login_button.setOnClickListener(new Button.OnClickListener(){ public void onClick(View v) { String input_pwd = et.getText().toString(); if(password.equals(input_pwd)){ Toast.makeText(Login.this, R.string.login_success, Toast.LENGTH_LONG).show(); Intent intent = new Intent(Login.this,MainActivity.class); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); finish(); }else{ Toast.makeText(Login.this, R.string.error_password, Toast.LENGTH_LONG).show(); et.setText(""); } } }); } }
