创立一种名为“登录页面”旳布局文献，该文献用于展示登录信息。程序界面如下图所示：
package com.example.mylayout1;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;
public class Activity01 extends Activity {
EditText name;
EditText pass ;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.myline);
name=(EditText)findViewById(R.id.editText1);
pass=(EditText)findViewById(R.id.editText2);}
public void click(View view){
Intent intent1=new Intent(this,Mylayout1MainActivity.class);
startActivity(intent1);}
public void click1(View view){
SharedPreferences sf1=getSharedPreferences("account",Context.MODE_PRIVATE);
String name1=sf1.getString("name","");
String pass1=sf1.getString("pass","");
String name2=name.getText().toString();
String pass2=pass.getText().toString();
if(name1.equals(name2)&&pass1.equals(pass2)){
Intent intent2=new Intent(this, Textview1.class);
intent2.putExtra("name", name1);
intent2.putExtra("pass", pass1);
startActivity(intent2);}
else{
String co="您旳顾客名或密码错误";
Toast.makeText(this, co.toString(), 1000).show();}}
private SharedPreferences getSharedPreference() {
return null;}}

创立一种名为“注册页面”旳布局文献，该文献用于展示登录信息。程序界面如下图所示：
package com.example.mylayout1;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.view.Menu;
import android.view.View;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.Spinner;
import android.widget.TextView;
public class Mylayout1MainActivity extends Activity {
EditText uname;
EditText upass;
RadioButton radio1;
RadioButton radio2;
RadioGroup group1;
String sex;
String name;
String pass;
CheckBox box1;
CheckBox box2;
CheckBox box3;
CheckBox box4;
String str1;
String str2;
String str3;
String str4;
Spinner sp;
String sp1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mylayout1_main);
group1=( RadioGroup)findViewById(R.id.radioGroup1);
uname=(EditText)findViewById(R.id.editText2);
upass=(EditText)findViewById(R.id.editText3);
box1=(CheckBox)findViewById(R.id.checkBox1);
box2=(CheckBox)findViewById(R.id.checkBox2);
box3=(CheckBox)findViewById(R.id.checkBox3);
box4=(CheckBox)findViewById(R.id.checkBox4);
sp=(Spinner)findViewById(R.id.spinner1) ; }
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.mylayout1_main, menu);
return true;}
public void click(View view){
for(int i=0;i<group1.getChildCount();i++){
radio1=(RadioButton)group1.getChildAt(i);
if(radio1.isChecked()){
sex=radio1.getText().toString();
break;}}
name=uname.getText().toString();
pass=upass.getText().toString();
if(box1.isChecked())str1=box1.getText().toString();
else str1="";
if(box2.isChecked())str2=box2.getText().toString();
else str2="";
if(box3.isChecked())str3=box3.getText().toString();
else str3="";
if(box4.isChecked())str4=box4.getText().toString();
else str4="";
sp1=(String)sp.getSelectedItem();
Intent intent1=new Intent(this,Textview2.class);
intent1.putExtra("name", name);
intent1.putExtra("pass", pass);
intent1.putExtra("sex", sex);
intent1.putExtra("str", str1+" "+str2+" "+str3+" "+str4);
intent1.putExtra("sp1", sp1);
startActivity(intent1);
SharedPreferences sf1=getSharedPreferences("account",MODE_PRIVATE);
Editor editor=sf1.edit();
editor.putString("name", name);
editor.putString("pass", pass);
editor mit(); }
public void click1(View view){
Intent intent2=new Intent(this,Activity01.class);
startActivity(intent2); }}

创立“登录成功页面”旳界面交互代码，该程序实现顾客信息显示。关键代码如下：
package com.example.mylayout1;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.widget.TextView;
public class Textview1 extends Activity {
TextView result;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_textview1);
Intent intent1=getIntent();
String str1=intent1.getStringExtra("name");
String str2=intent1.getStringExtra("pass");
result=(TextView)this.findViewById(R.id.text1);
result.setText("您已登录成功"+"\n"+"顾客名："+str1+"\n"+"密码:"+str2); }
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.textview1, menu);
return true;}}

创立“顾客信息显示界面”旳界面交互代码，该程序实现顾客信息显示。关键代码如下：
package com.example.mylayout1;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.widget.TextView;

public class Textview2 extends Activity {
TextView view1;
TextView view2;
TextView view3;
TextView view4;
TextView view5;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_textview2);
view1=(TextView)findViewById(R.id.textView1);
view2=(TextView)findViewById(R.id.textView2);
view3=(TextView)findViewById(R.id.textView3);
view4=(TextView)findViewById(R.id.textView4);
view5=(TextView)findViewById(R.id.textView5);
Intent intent1=getIntent();
String name=intent1.getStringExtra("name");
String pass=intent1.getStringExtra("pass");
String sex=intent1.getStringExtra("sex");
String str=intent1.getStringExtra("str");
String sp1=intent1.getStringExtra("sp1");
view1.setText(name);
view2.setText(pass);
view3.setText(sex);
view4.setText(str);
view5.setText(sp1);
}
public void click1(View view){
Intent intent1=new Intent(this, Activity01.class);
startActivity(intent1);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.textview2, menu);
return true;
}
}
