Android仿QQ登录注册界面_SQlite实现本地缓存

本Demo是一个高仿QQ登录、注册和修改密码的界面以及找回密码功能、并且带有sqlite数据库缓存数据、封装了sqlite常用的工具类、代码是通过Activity来做的、Layout集成起来非常方便、下面是运行效果图

初始化代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_login);
    helper = new MyDatabaseHelper(this);
    initView();
    Intent i = super.getIntent();
    String Id = i.getStringExtra("myId");
    loginId.setText(Id);
}

// 控件的初始化
private void initView() {
    loginId = (EditText) findViewById(R.id.loginId);
    loginPassword = (EditText) findViewById(R.id.loginPassword);
    loginBtn = (Button) findViewById(R.id.loginBtn);
    loginBtn.setOnClickListener(this);
    loginMissps = (Button) findViewById(R.id.loginMissps);
    loginMissps.setOnClickListener(this);
    loginNewUser = (Button) findViewById(R.id.loginNewUser);
    loginNewUser.setOnClickListener(this);
    loginChangePw = (Button) findViewById(R.id.loginChangePw);
    loginChangePw.setOnClickListener(this);
}

onClick处理

// 控件的点击事件
@Override
public void onClick(View v) {
    switch (v.getId()) {
    case R.id.loginBtn:
        isId = loginId.getText().toString();
        isPs = loginPassword.getText().toString();
        if (new MyloginCursor(
                LoginActivity.this.helper.getReadableDatabase()).find(isId)
                .size() == 0) {
            // Toast弹窗
            Toast.makeText(LoginActivity.this, "手机号未注册，请注册后登录",
                    Toast.LENGTH_SHORT).show();
        } else {
            String lph = new MyloginCursor(
                    LoginActivity.this.helper.getReadableDatabase()).find(
                    isId).toString();
            // 对查询出来的数据进行拆分
            String result[] = lph.split(",");
            if (result[1].equals(isId) && result[2].equals(isPs)) {
                Toast.makeText(LoginActivity.this, "登录成功",
                        Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(LoginActivity.this, "用户名或密码错误",
                        Toast.LENGTH_SHORT).show();
            }
        }
        break;
    case R.id.loginMissps:
        Intent a = new Intent(LoginActivity.this,
                FindPasswordActivity.class);
        startActivity(a);
        break;
    case R.id.loginNewUser:
        Intent i = new Intent(LoginActivity.this, RegisterActivity.class);
        startActivity(i);
        break;
    case R.id.loginChangePw:
        Intent l = new Intent(LoginActivity.this,
                ChangePasswordActivity.class);
        startActivity(l);
        break;
    default:
        break;
    }
