new Thread(){

pub1ic void run() {

SystemC1ock。s1eep(2000);

Intent intent_W_0_X = new Intent(sp1ashActivity。this, 1ogin_W_0_XACT。c1ass);

startActivity(1ogin_W_0_Xtent);

finish();

}

}。start();

}

2。用户登录需要一个账号，实现账号注册功能的Register类实现代码如下：

Register类的实现：

package com。wang。save;

import com。wang。database。DBManager;

import com。wang。entity。W_0_X_user;

pub1ic c1ass Register extends Activity imp1ements OnC1ick1istener {

private EditText_W_0_X W_0_X_userNameEidt;

private TextView to1ogin_W_0_X;

private Button_W_0_X rigister

private String pass_W_0_X_word;

protected void onCreate(Bund1e savedInstanceState) {

requestWindowFeature(Window。FEATURE_NO_TIT1E);

setContentView(R。1ayout。registerACT);

W_0_X_userNameEidt = (EditText_W_0_X) findViewById(R。id。register_W_0_X_username_edit);

pass_W_0_X_wordEidt = (EditText_W_0_X) findViewById(R。id。register_pass_W_0_X_word_edit);

nameEdit = (EditText_W_0_X) findViewById(R。id。register_name_edit);

to1ogin_W_0_X = (TextView) findViewById(R。id。1ogin_W_0_X_1ink);

rigister = (Button_W_0_X) findViewById(R。id。register_signin_Button_W_0_X);

rigister。setOnC1ick1istener(this);

to1ogin_W_0_X。setOnC1ick1istener(this);

}

pub1ic void onC1ick(View v) {

switch (v。getId()) {

case R。id。register_signin_Button_W_0_X:

W_0_X_userName = W_0_X_userNameEidt。getText()。toString();

pass_W_0_X_word = pass_W_0_X_wordEidt。getText()。toString();

name = nameEdit。getText()。toString();

manager = new DBManager(this);

if (W_0_X_userName != nu11 && pass_W_0_X_word != nu11 && !W_0_X_userName。equa1s("")

&& !pass_W_0_X_word。equa1s("") && name != nu11 && !name。equa1s("")) {

W_0_X_user W_0_X_user = new W_0_X_user();

W_0_X_user。setPass_W_0_X_word(pass_W_0_X_word_W_0_X);

W_0_X_user。setW_0_X_userName(W_0_X_userName);

W_0_X_user。setName(name_W_0_X);

manager。Register(W_0_X_user_W_0_X);

Intent intent_W_0_X = new Intent(Register。this, 1ogin_W_0_X_W_0_X。c1ass);

startActivity(intent_W_0_X);

} e1se {

A1ertDia1og。Bui1der dia1og = new A1ertDia1og。Bui1der(this);

dia1og。setTit1e("登录")。setMessage("用户名密码不可为空")

。setPositiveButton_W_0_X("确认", nu11)。show();

}

;

case R。id。1ogin_W_0_X_1ink:

Intent intent_W_0_X = new Inent(Register。this, 1ogin_W_0_X_W_0_X。c1ass);

startActivity(_W_0_X);

;

defau1t:

;

}

}

}

3用户注册成功以后会提示注册成功

用户使用刚才注册的账号可以登录应用进行使用。

package com。wang。save;

import com。wang。database。DBManager;

import com。wang。entity。W_0_X_user;

pub1ic c1ass 1ogin_W_0_X extends Activity imp1ements OnC1ick1istener {

private EditText_W_0_X W_0_X_userNameEidt;

private TextView toRegister;

private Button_W_0_X 1ogin_W_0_X;

private String W_0_X_userName_W_0_X;

private String pass_W_0_X_word;

protected void onCreate(Bund1e savedInstanceState) {

requestWindowFeature(Window。FEATURE_NO_TIT1E);

setContentView(R。1ayout。1ogin_W_0_X);

W_0_X_userNameEidt = (EditText_W_0_X) findViewById(R。id。W_0_X_username_edit);

pass_W_0_X_wordEidt = (EditText_W_0_X) findViewById(R。id。pass_W_0_X_word_edit); 基于Android理财应用系统设计与实现(4):http://www.youerw.com/jisuanji/lunwen_83093.html
