public class Activity01 extends Activity {

EditText name; EditText pass ;

protected void onCreate(Bundle savedInstanceState) {

(savedInstanceState);

public void click(View view){

Intent intent1=new Intent(this,; startActivity(intent1);}

public void click1(View view){

SharedPreferences sf1=getSharedPreferences(\"account\String name1=(\"name\String pass1=(\"pass\String name2=().toString(); String pass2=().toString(); if(name2)&&(pass2)){

Intent intent2=new Intent(this, ; (\"name\(\"pass\

startActivity(intent2);}

else{

String co=\"您的用户名或密码错误\"; (this, (), 1000).show();}}

private SharedPreferences getSharedPreference() {

return null;}}

创建一个名为“注册页面”的布局文件，该文件用于展示登录信息。程序界面如下图所示：

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) {

(savedInstanceState);

@Override

public boolean onCreateOptionsMenu(Menu menu) {

return true;}

public void click(View view){ for(int i=0;i<();i++){ radio1=(RadioButton)(i); if()){ sex=().toString();

break;}}

name=().toString(); pass=().toString(); if())str1=().toString(); else str1=\"\";

if())str2=().toString(); else str2=\"\";

if())str3=().toString();

else str3=\"\";

if())str4=().toString(); else str4=\"\"; sp1=(String)();

Intent intent1=new Intent(this,; (\"name\ (\"pass\ (\"sex\

(\"str\ (\"sp1\

startActivity(intent1);

SharedPreferences sf1=getSharedPreferences(\"account\ Editor editor=(); (\"name\ (\"pass\ (); }

public void click1(View view){

Intent intent2=new Intent(this,; startActivity(intent2); }}

创建“登录成功页面”的界面交互代码，该程序实现用户信息显示。关键代码如下：

public class Textview1 extends Activity {

TextView result;

protected void onCreate(Bundle savedInstanceState) {

(savedInstanceState); Intent intent1=getIntent(); String str1=(\"name\"); String str2=(\"pass\");

(\"您已登录成功\"+\"\\n\"+\"用户名：\"+str1+\"\\n\"+\"密码:\"+str2); }

public boolean onCreateOptionsMenu(Menu menu) {

return true;}}

创建“用户信息显示界面”的界面交互代码，该程序实现用户信息显示。关键代码如下：

public class Textview2 extends Activity {

TextView view1; TextView view2; TextView view3; TextView view4; TextView view5; @Override

protected void onCreate(Bundle savedInstanceState) {

(savedInstanceState); Intent intent1=getIntent(); String name=(\"name\"); String pass=(\"pass\"); String sex=(\"sex\"); String str=(\"str\"); String sp1=(\"sp1\");

(name); (pass); (sex); (str); (sp1);

}

public void click1(View view){ Intent intent1=new Intent(this, ; startActivity(intent1);

} @Override

public boolean onCreateOptionsMenu(Menu menu) {

return true;

}

}
