我有一個包含BroadcastReceiver的Fragment，它包含在Activity中。活動具有意圖 - 篩選以確定應用程序鏈接。在片段中的一些操作之後，我通過應用程序鏈接從服務器獲取電子郵件。所以當我點擊設備上的home按鈕時，應用程序不會銷燬，當我點擊電子郵件中的鏈接時，必須打開一個新的片段，但是我有一個IllegalStateException，並且文本爲Can not perform this action after saveInstanceState。如何解決它？下面我附上了我的活動，兩個片段代碼：當通過另一個應用程序運行應用程序時，Android無法執行saveInstanceState後的此操作
public class PerfectoActivity extends AppCompatActivity implements ProgressUpdater, AuthFragment.ProgressActivator {
@Bind(R.id.sign_up_progress) ProgressBar mSignUpProgressBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_perfecto);
ButterKnife.bind(this);
if (cameFromMail()) {
if (isSignUpProcess()) {
mSignUpProgressBar.setVisibility(View.VISIBLE);
String login = Utils.getLogin(this);
String password = Utils.getPassword(this);
String username = Utils.getUsername(this);
String phone = Utils.getPhone(this);
Utils.removePasswordAndPhone(this);
ApiService.startActionAuth(this, login, password);
getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, SignUpThirdStepFragment.newInstance(username, phone)).commit();
} else {
String login = Utils.getLogin(this);
String resetCode = Utils.getResetCode(this);
ApiService.startActionCheckConfirmReset(this, login, resetCode);
getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, ResetPasswordFourthStepFragment.newInstance(login, resetCode)).commit();
}
} else {
Utils.removePasswordAndPhone(this);
getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, new AuthFragment()).commit();
}
}
private boolean isSignUpProcess() {
Intent intent = getIntent();
if (intent.getData() != null) {
if (intent.getData().getLastPathSegment().equals("confirmreset")) {
return false;
}
return true;
}
return false;
}
private boolean cameFromMail() {
Intent intent = getIntent();
if (intent.getData() != null)
if (Intent.ACTION_VIEW.equals(intent.getAction())) return true;
return false;
}
@Override
public void updateProgress(int progress) {
mSignUpProgressBar.setProgress(progress);
}
@Override
public void activateProgress() {
if (mSignUpProgressBar.getVisibility() == View.VISIBLE) {
mSignUpProgressBar.setVisibility(View.GONE);
}
else {
mSignUpProgressBar.setVisibility(View.VISIBLE);
}
}
}
這是第一個片段
public class ResetPasswordSecondStepFragment extends Fragment {
private static final String BUNDLE_LOGIN = "com.rcd.perfecto.fragments.ResetPasswordSecondStep.bundle.LOGIN";
public static final String RESET_PASSWORD_FILTER = "com.rcd.perfecto.fragments.filter.RESET_PASSWORD";
private String mLogin;
private BroadcastReceiver mReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (!intent.getBooleanExtra(ApiService.EXTRA_SUCCESS, false)) {
mPhoneErrorTextView.setVisibility(View.VISIBLE);
mPhoneErrorTextView.setText(intent.getStringExtra(ApiService.EXTRA_MESSAGE));
} else {
String phone = mLastDigitsEditText.getText().toString();
String resetCode = intent.getStringExtra(ApiService.EXTRA_DATA);
FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.fragment_container, ResetPasswordThirdStepFragment.newInstance(mLogin, phone, resetCode)).commit();
}
}
};
@Bind(R.id.et_last_digits) EditText mLastDigitsEditText;
@Bind(R.id.tv_phone_error) TextView mPhoneErrorTextView;
@OnTextChanged(R.id.et_last_digits)
void resetPassword(CharSequence digits) {
if (digits.length() == 4) ApiService.startActionResetPassword(getActivity(), mLogin, mLastDigitsEditText.getText().toString());
}
public ResetPasswordSecondStepFragment() {
// Required empty public constructor
}
public static ResetPasswordSecondStepFragment newInstance(String login) {
ResetPasswordSecondStepFragment fragment = new ResetPasswordSecondStepFragment();
Bundle args = new Bundle();
args.putString(BUNDLE_LOGIN, login);
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle args = getArguments();
if (args != null) {
mLogin = args.getString(BUNDLE_LOGIN);
}
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(mReceiver, new IntentFilter(RESET_PASSWORD_FILTER));
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_reset_password_second_step, container, false);
ButterKnife.bind(this, view);
return view;
}
@Override
public void onDestroy() {
super.onDestroy();
LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(mReceiver);
}
}
，最後一個
public class ResetPasswordThirdStepFragment extends Fragment {
private static final String BUNDLE_LOGIN = "com.rcd.perfecto.fragments.bundle.LOGIN";
private static final String BUNDLE_RESET_CODE = "com.rcd.perfecto.fragments.bundle.RESET_CODE";

if (!intent.getBooleanExtra(ApiService.EXTRA_SUCCESS, false)) {
Utils.showAlert(R.string.reset_password_error, intent.getStringExtra(ApiService.EXTRA_MESSAGE), getActivity());
} else {
if (intent.getBooleanExtra(ApiService.EXTRA_DATA, false)) {
FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.fragment_container, ResetPasswordFourthStepFragment.newInstance(mLogin, mResetCode)).commit();
} else {

}
}
};

}
}
};
@Bind(R.id.btn_continue) Button mContinueButton;
@Bind(R.id.tv_not_got_email) TextView mNotGotMailTextView;

void confirmResetting() {

}
@OnClick(R.id.tv_not_got_email)
void sendConfirmationAgaing() {
ApiService.startActionResetPassword(getActivity(), mLogin, mPhone);
}
public ResetPasswordThirdStepFragment() {
// Required empty public constructor
}
public static ResetPasswordThirdStepFragment newInstance(String login, String phone, String resetCode) {
ResetPasswordThirdStepFragment fragment = new ResetPasswordThirdStepFragment();
Bundle args = new Bundle();
args.putString(BUNDLE_LOGIN, login);

return fragment;
}
@Override

Utils.saveResetCode(getActivity(), mResetCode);
}
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(mConfirmReceiver, new IntentFilter(CHECK_CONFIRM_RESET_FILTER));
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(mSendConfirmationReceiver, new IntentFilter(ResetPasswordSecondStepFragment.RESET_PASSWORD_FILTER));
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,

return view;
}
@Override

LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(mSendConfirmationReceiver);
}
}
謝謝。有用！ –
