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 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);

//给Spinner设置适配器

//设置下拉菜单样式
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

//事件监听
notify.setOnCheckedChangeListener(new OnCheckedChangeListener() {

register.setOnClickListener(new OnClickListener() {
@Override

.show();
return;

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;
}
}
