android 注册页面实现
自己动手做的第一个demo，简单的注册页面的实现，并且注册成功后返回注册信息，适用于android新手基本控件的使用。
注册页面的实现：
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.EditText;
import android.widget.RadioGroup;
import android.widget.Spinner;
import android.widget.ToggleButton;
public class RegisterActivity extends Activity {
private static final String places[] = {"中国","中国香港","中国台湾","中国澳门"};
private boolean isNotified = false;
private int sexFlag = 0;
private boolean isChecked = false;
private int plcFlag = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
//设置标题
setTitle("注册成功");
//获取控件
final EditText username = (EditText)findViewById(R.id.username);
final EditText pwd = (EditText)findViewById(R.id.pwd);
final EditText pwdrp = (EditText)findViewById(R.id.pwdrp);
RadioGroup sex = (RadioGroup)findViewById(R.id.sex);
Spinner from = (Spinner)findViewById(R.id.from);
final EditText mail= (EditText)findViewById(R.id.mail);
ToggleButton notify = (ToggleButton)findViewById(R.id.notify);
CheckBox check = (CheckBox)findViewById(R.id.check);
Button register = (Button)findViewById(R.id.register);
Button cancel = (Button)findViewById(R.id.cancel);
//给Spinner设置适配器
ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_spinner_item,places);
//设置下拉菜单样式
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
from.setAdapter(adapter);
//事件监听
notify.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton arg0, boolean flag) {
// TODO Auto-generated method stub
isNotified = flag;
}
});
check.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton arg0, boolean flag) {
// TODO Auto-generated method stub
isChecked = flag;
}
});
sex.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup arg0, int flag) {
// TODO Auto-generated method stub
sexFlag = flag;
}
});
from.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0,View arg1,int flag,long arg3){
plcFlag = flag;
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
register.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
String strUser = username.getText().toString();
String strPwd = pwd.getText().toString();
String strPwdrp = pwdrp.getText().toString();
String strMail = mail.getText().toString();
if(strUser.equals("")){
//弹出对话框
new AlertDialog.Builder(RegisterActivity.this)
.setIcon(android.R.drawable.ic_dialog_alert)
.setTitle("警告")
.setMessage("请输入用户名")
.setPositiveButton("确定", null)
.show();
return;
}
if(!strPwd.equals(strPwdrp)){
//弹出对话框
new AlertDialog.Builder(RegisterActivity.this)
.setIcon(android.R.drawable.ic_dialog_alert)
.setTitle("警告")
.setMessage("两次输入的密码不相同")
.setPositiveButton("确定", null)
.show();
return;
}
if(!isChecked){
//弹出对话框
new AlertDialog.Builder(RegisterActivity.this)
.setIcon(android.R.drawable.ic_dialog_alert)
.setTitle("警告")
.setMessage("请勾选同意条款")
.setPositiveButton("确定", null)
.show();
return;
}
//发送数据到另一个Activity
Bundle bundle = new Bundle();
bundle.putString("username", strUser);
bundle.putString("mail", strMail);
bundle.putString("from", places[plcFlag]);
//bundle.putString("from", "中国");
bundle.putBoolean("notify", isNotified);
bundle.putBoolean("check", isChecked);
bundle.putInt("sex", sexFlag);
Intent intent = new Intent(RegisterActivity.this,ResultActivity.class);
intent.putExtra("info", bundle);
//启动这个Activity
RegisterActivity.this.startActivity(intent);
//结束本Activity
RegisterActivity.this.finish();
}
});
cancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
RegisterActivity.this.finish();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.register, menu);
return true;
}
}
注册结果显示activity：
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class ResultActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.registerresult);
//设置标题
setTitle("注册成功");
//接收数据
Intent intent = this .getIntent();
Bundle bundle = intent.getBundleExtra("info");
String strUsername = bundle.getString("username");
String strMail = bundle.getString("mail");
String strFrom = bundle.getString("from");
String strNotify = bundle.getBoolean("notify") ? "是":"否";;
String strSex = bundle.getInt("sexFlag") == 0 ? "男":"女";;
TextView username = (TextView)findViewById(R.id.username);
username.setText(strUsername);
TextView mail = (TextView)findViewById(R.id.mail);
mail.setText(strMail);
TextView from = (TextView)findViewById(R.id.from);
from.setText(strFrom);
TextView notify = (TextView)findViewById(R.id.notify);
notify.setText(strNotify);
TextView sex = (TextView)findViewById(R.id.sex);
sex.setText(strSex);
Button doneBt = (Button)findViewById(R.id.done);
doneBt.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
ResultActivity.this.finish();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.register, menu);
return true;
}
}
