我正在尝试使用Realm Mobile Database，但我遇到了一些问题：
我安装了Realm对象服务器，并尝试使用活动创建一个用途。
这是我的RegisterActivity
public class RegisterActivity extends AppCompatActivity implements SyncUser.Callback {
private AutoCompleteTextView usernameView;
private EditText passwordView;
private EditText passwordConfirmationView;
private View progressView;
private View registerFormView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
usernameView = (AutoCompleteTextView) findViewById(R.id.username);
passwordView = (EditText) findViewById(R.id.password);
passwordConfirmationView = (EditText) findViewById(R.id.password_confirmation);
passwordConfirmationView.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView textView, int id, KeyEvent keyEvent) {
if (id == R.id.register || id == EditorInfo.IME_NULL) {
attemptRegister();
return true;
}
return false;
}
});
final Button mailRegisterButton = (Button) findViewById(R.id.email_register_button);
mailRegisterButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
attemptRegister();
}
});
registerFormView = findViewById(R.id.register_form);
progressView = findViewById(R.id.register_progress);
}
private void attemptRegister() {
usernameView.setError(null);
passwordView.setError(null);
passwordConfirmationView.setError(null);
final String username = usernameView.getText().toString();
final String password = passwordView.getText().toString();
final String passwordConfirmation = passwordConfirmationView.getText().toString();
boolean cancel = false;
View focusView = null;
if (isEmpty(username)) {
usernameView.setError(getString(R.string.error_field_required));
focusView = usernameView;
cancel = true;
}
if (isEmpty(password)) {
passwordView.setError(getString(R.string.error_field_required));
focusView = passwordView;
cancel = true;
}
if (isEmpty(passwordConfirmation)) {
passwordConfirmationView.setError(getString(R.string.error_field_required));
focusView = passwordConfirmationView;
cancel = true;
}
if (!password.equals(passwordConfirmation)) {
passwordConfirmationView.setError(getString(R.string.error_incorrect_password));
focusView = passwordConfirmationView;
cancel = true;
}
if (cancel) {
focusView.requestFocus();
} else {
showProgress(true);
SyncUser.loginAsync(SyncCredentials.usernamePassword(username, password, true), AUTH_URL, new SyncUser.Callback() {
@Override
public void onSuccess(SyncUser user) {
registrationComplete(user);
}
@Override
public void onError(ObjectServerError error) {
showProgress(false);
String errorMsg;
switch (error.getErrorCode()) {
case EXISTING_ACCOUNT:
errorMsg = "Account already exists";
break;
default:
errorMsg = error.toString();
}
RealmLog.info(errorMsg);
Toast.makeText(RegisterActivity.this, errorMsg, Toast.LENGTH_LONG).show();
}
});
}
}
private void registrationComplete(SyncUser user) {
UserManager.setActiveUser(user);
Intent intent = new Intent(this, LoginActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
private void showProgress(final boolean show) {
final int shortAnimTime = getResources().getInteger(android.R.integer.config_shortAnimTime);
registerFormView.setVisibility(show ? View.GONE : View.VISIBLE);
registerFormView.animate().setDuration(shortAnimTime).alpha(
show ? 0 : 1).setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
registerFormView.setVisibility(show ? View.GONE : View.VISIBLE);
}
});
progressView.setVisibility(show ? View.VISIBLE : View.GONE);
progressView.animate().setDuration(shortAnimTime).alpha(
show ? 1 : 0).setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
progressView.setVisibility(show ? View.VISIBLE : View.GONE);
}
});
}
@Override
public void onSuccess(SyncUser user) {
registrationComplete(user);
}
@Override
public void onError(ObjectServerError error) {
String errorMsg;
switch (error.getErrorCode()) {
case EXISTING_ACCOUNT:
errorMsg = "Account already exists";
break;
default:
errorMsg = error.toString();
}
RealmLog.info(errorMsg);
Toast.makeText(RegisterActivity.this, errorMsg, Toast.LENGTH_LONG).show();
}
}
但是当我点击验证或我的视图上的按钮时，它会崩溃堆栈

或者当我评论所有RealmLog行

答案 0 :(得分：6)
您需要先调用init
Realm.init()
