這裏是我的我的signupactivity &主要活動和他們的XML應用程序崩潰
public class SignupActivity extends AppCompatActivity {
protected EditText mUsername;
protected EditText mPassword;
protected EditText mEmail;
protected Button nbutton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signup);
mUsername = (EditText) findViewById(R.id.usernamefield);
mPassword = (EditText) findViewById(R.id.passwordtextfield);
mEmail = (EditText) findViewById(R.id.emailtextfield);
nbutton = (Button) findViewById(R.id.signbutton);
nbutton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view){
// Retrieve the text entered from the EditText
String usernametxt = mUsername.getText().toString();
String password = mPassword.getText().toString();
String email= mEmail.getText().toString();
// Force user to fill up the form
if (usernametxt.equals("") && password.equals("")) {
Toast.makeText(getApplicationContext(),
"Please complete the sign up form",
Toast.LENGTH_LONG).show();
} else {
// Save new user data into Parse.com Data Storage
ParseUser newUser = new ParseUser();
newUser.setUsername(usernametxt);
newUser.setPassword(password);
newUser.setEmail(email);
newUser.signUpInBackground(new SignUpCallback() {
@Override
public void done(ParseException e) {
//SUCESS
if (e!= null){
AlertDialog.Builder builder=new AlertDialog.Builder(SignupActivity.this);
builder.setMessage(e.getMessage()).setTitle(R.string.signup_error_title).setPositiveButton(android.R.string.ok, null);
AlertDialog dialog = builder.create();
dialog.show();
}
else {
Intent intent= new Intent(SignupActivity.this,MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}
}
});
}
}
});
}
