问题描述
这是登录页面在我的应用程序，现在我想创建注册页面。我认为它容易使在登录类的变化作出新的注册类。我已经尝试了很多，但无力。而我之所以想从本作的注册页面是，在登录类，我有我的远程服务器连接成功。注册类我想重新输入密码和手机2个编辑的文本字段。此外，在登录类，你看，我有复选框，但注册类我不想复选框。因此，其对我来说很难将其转换。如果有人愿意帮助我。请尝试。

This is login page in my app and now i want to create sign up page. I think its easy to make changes in the login class to make new signup class. I have tried a lot but unable. And reason why i want to make signup page from this is that in login class i have successful connection with my remote server. In sign up class i want 2 more edit text field for re-type password and mobile. Also in login class as you see i have check box but in sign up class i do not want check box. Therefore its difficult for me to convert it. If someone like to help me. Please try.
LoginActivity Class-
public class LoginActivity extends Activity {
Intent i;
Button signin, signup;
TextView error;
CheckBox check;
String name = "", pass = "";
byte[] data;
HttpPost httppost;
StringBuffer buffer;
HttpResponse response;
HttpClient httpclient;
InputStream inputStream;
SharedPreferences app_preferences;
List<NameValuePair> nameValuePairs;
EditText editTextId, editTextP;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
signin = (Button) findViewById(R.id.signin);
editTextId = (EditText) findViewById(R.id.editTextId);
editTextP = (EditText) findViewById(R.id.editTextP);
app_preferences = PreferenceManager.getDefaultSharedPreferences(this);
check = (CheckBox) findViewById(R.id.check);
String Str_user = app_preferences.getString("username", "0");
String Str_pass = app_preferences.getString("password", "0");
String Str_check = app_preferences.getString("checked", "no");
if (Str_check.equals("yes")) {
editTextId.setText(Str_user);
editTextP.setText(Str_pass);
check.setChecked(true);
}
signin.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
name = editTextId.getText().toString();
pass = editTextP.getText().toString();
String Str_check2 = app_preferences.getString("checked", "no");
if (Str_check2.equals("yes")) {
SharedPreferences.Editor editor = app_preferences.edit();
editor.putString("username", name);
editor.putString("password", pass);
editor.commit();
}
if (name.equals("") || pass.equals("")) {
Toast.makeText(LoginActivity.this, "Blank Field..Please Enter", Toast.LENGTH_SHORT).show();
} else {
new LoginTask().execute();
}
}
});
check.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on clicks, depending on whether it's now
// checked
SharedPreferences.Editor editor = app_preferences.edit();
if (((CheckBox) v).isChecked()) {
editor.putString("checked", "yes");
editor.commit();
} else {
editor.putString("checked", "no");
editor.commit();
}
}
});
}
public void Move_to_next()
{
startActivity(new Intent(LoginActivity.this, SplashActivity.class));
finish();
}
@SuppressLint("NewApi")
private class LoginTask extends AsyncTask <Void, Void, String>

while (-1 != (len = inputStream.read(data))) {
buffer.append(new String(data, 0, len));
}
inputStream.close();
return buffer.toString();
}
catch (Exception e)
{
e.printStackTrace();
}
return "";
}
@SuppressLint("NewApi")
@Override
protected void onPostExecute(String result) {

// Hide progress dialog here
if (buffer.charAt(0) == 'Y') {
Toast.makeText(LoginActivity.this, "login successfull", Toast.LENGTH_SHORT).show();
Move_to_next();
} else {
Toast.makeText(LoginActivity.this, "Invalid Username or password", Toast.LENGTH_SHORT).show();
