Showing specific button to current user in Android

My app has a post layout which have an edit button and the send button. All i want to do is to show only edit button if current user is viewing his/her post and not the send button. Just like a stackoverflow post, you can't edit other's post and can't send a message to yourself. I have tried boolean methods but still no solution. Thanks.

what are the values for mPostId?
I would log the userID and currentuser values thats being retrieved, to check if there is no issue your query. The boolean part should work

LiveData observer triggered after reloading fragment

My MainAcivity hosts 2 fragments, login and register. I have a LiveData observer on LoginFragment that observes user login live data, after which if user is authenticated MainMenuActivity intent will start. On main menu there's logout button that would start MainActivity and load LoginFragment.
But here's the problem, the observer on LoginFragment triggered immediately after loading the fragment, which straight up start MainMenuActivity intent again.
My LoginFragment:
public class LoginFragment extends Fragment {
public static LoginFragment newInstance(){
return new LoginFragment();
}
private LoginViewModel mLoginViewModel;
private LiveData<UserModelJSONPlaceholder> mUserModelLiveData;
private static final String TAG = "FragLogin";
private Button mBtnLogin;
private EditText mTxtUsername, mTxtPass;
private TextView mTxtRegister;
private CheckBox mCheckBoxRemember;
private TextView mTxtInvalid;
private Callbacks mCallbacks = null;
private ProgressBar mProgressBar;
private UserApiInterface mAPIInterface;
private SharedPreferences mSharedPreferences;
private SharedPreferences.Editor mPreferencesEditor;
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_login,container,false);
mBtnLogin = view.findViewById(R.id.btnLogin_login);
mTxtUsername = view.findViewById(R.id.txtUsername);
mTxtPass = view.findViewById(R.id.txtPass);
mCheckBoxRemember = view.findViewById(R.id.checkBoxRememberMe);
mTxtRegister = view.findViewById(R.id.txtRegister_login);
mProgressBar = view.findViewById(R.id.progressBar);
mTxtInvalid = view.findViewById(R.id.txtInvalid);
mProgressBar.setVisibility(View.GONE);
mTxtInvalid.setVisibility(View.GONE);
mAPIInterface = APIClient.getClient().create(UserApiInterface.class);
mSharedPreferences = getContext().getSharedPreferences("login",Context.MODE_PRIVATE);
mPreferencesEditor = mSharedPreferences.edit();
setListener();
return view;
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mLoginViewModel = new ViewModelProvider(this).get(LoginViewModel.class);
mUserModelLiveData = mLoginViewModel.getUserModelLiveData();
//observer would be triggered right after loading fragment after logout
mUserModelLiveData.observe(this, new Observer<UserModelJSONPlaceholder>() {
#Override
public void onChanged(UserModelJSONPlaceholder userModel) {
Log.d(TAG, "onChanged: Observer: "+userModel.getResponse());
mProgressBar.setVisibility(View.GONE);
String loginAuth = userModel.getResponse();
if(loginAuth.equals("OK")){
mPreferencesEditor.putString("name",userModel.getUserModel().getName());
mCallbacks.login_goMainMenu(userModel.getUserModel().getName());
}else{
mTxtInvalid.setVisibility(View.VISIBLE);
}
}
});
}
private void doLogin(){
mProgressBar.setVisibility(View.VISIBLE);
final String username = mTxtUsername.getText().toString().trim();
final String password = mTxtPass.getText().toString().trim();
mLoginViewModel.authLogin(username,password);
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
mCallbacks = (Callbacks) context;
}
private void setListener(){
mBtnLogin.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
doLogin();
}
});
mTxtRegister.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mCallbacks.login_goRegister();
}
});
mCheckBoxRemember.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(buttonView.isChecked()){
mPreferencesEditor.putBoolean("rememberMe", true).apply();
Log.d(TAG, "onCheckedChanged: Checked");
}else{
mPreferencesEditor.putBoolean("rememberMe", false).apply();
Log.d(TAG, "onCheckedChanged: Unchecked");
}
}
});
}
public interface Callbacks{
void login_goMainMenu(String name);
void login_goRegister();
}
}
My MainMenuActivity:
public class MainMenuActivity extends AppCompatActivity {
private static final String ARG_NAME = "arg_name";
private Button mBtnEnterQ,mBtnCreateQ;
private TextView mTxtName;
private Toolbar mToolbar;
private SharedPreferences mSharedPreferences;
private SharedPreferences.Editor mEditor;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_menu);
mBtnEnterQ = findViewById(R.id.btnEnterQ);
mBtnCreateQ = findViewById(R.id.btnCreateQ);
mTxtName = findViewById(R.id.txtUsername);
mToolbar = findViewById(R.id.toolbar);
mSharedPreferences = getSharedPreferences("login",MODE_PRIVATE);
mEditor = mSharedPreferences.edit();
setSupportActionBar(mToolbar);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.toolbar_menu,menu);
return true;
}
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()){
case R.id.itemLogout:
doLogout();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private void doLogout(){
mEditor.remove("rememberMe");
mEditor.apply();
Intent i = new Intent(this, MainActivity.class);
startActivity(i);
finish();
}
}
and here's my ViewModel and Repo for LoginFragment:
public class LoginViewModel extends ViewModel {
private static final String TAG = "LoginVM";
private UserRepository mUserRepository;
LiveData<UserModelJSONPlaceholder> mUserModelLiveData;
public LoginViewModel() {
mUserRepository = UserRepository.getInstance();
}
public void authLogin(String username, String password){
mUserRepository.authLogin(username,password);
}
public LiveData<UserModelJSONPlaceholder> getUserModelLiveData() {
return mUserRepository.getUserModelLiveData();
}
}
public class UserRepository {
private static UserRepository instance;
private static final String TAG = "RepoUser";
private UserApiInterface mUserApiInterface;
MutableLiveData<UserModelJSONPlaceholder> userModelLiveData;
public static UserRepository getInstance(){
if(instance==null){
instance=new UserRepository();
}
return instance;
}
private UserRepository(){
mUserApiInterface = APIClient.getClient().create(UserApiInterface.class);
Log.d(TAG, "UserRepository: repoInit");
}
public void authLogin(String username, String password){
Log.d(TAG, "authLogin: REQUEST INIT");
Log.d(TAG, "authLogin: SERVER: "+ CONFIG.SERVER);
mUserApiInterface.getUser(username,password).enqueue(new Callback<UserModelJSONPlaceholder>() {
#Override
public void onResponse(Call<UserModelJSONPlaceholder> call, Response<UserModelJSONPlaceholder> response) {
if(response.isSuccessful()){
UserModelJSONPlaceholder r = response.body();
userModelLiveData.postValue(response.body());
}else{
Log.d(TAG, "onResponse: FAILED. "+response.errorBody());
}
}
#Override
public void onFailure(Call<UserModelJSONPlaceholder> call, Throwable t) {
Log.d(TAG, "onFailure: "+t.getMessage());
}
});
}
public LiveData<UserModelJSONPlaceholder> getUserModelLiveData() {
if(userModelLiveData == null)
userModelLiveData = new MutableLiveData<>();
return userModelLiveData;
}
}

Your problems is you make UserRepository is Singleton instance and always keep value of userModelLiveData easy way to fix it change method to this
public LiveData<UserModelJSONPlaceholder> getUserModelLiveData() {
userModelLiveData = new MutableLiveData<>();
return userModelLiveData;
}

Cannot click on interstitial ad in WebView fragment

I have made an AdvanceWebView Application.
In that I have made a function to show interstitialAd in "fragmentActivity", that means whenever I download something from that webview that Ad will show up but it isn't clickable.
I think my ad is showing behind that fragment or something like that or maybe some other issue.
And when Vedio Ads are showen, the countdown of that ad also doesn't woprking.
I can see the Ad but it isn't clickable and if I click on any part of Ad, Logcat
is showing this => "I/HwSecImmHelper: mSecurityInputMethodService is null"
Here it is some part of my code:

Android DialogFragment and EditText not restoring state

Please help me. I don't know why, but after screen rotation EditText is empty. I use setRetainInstance(true), but it doesn't help for me. Please tell me what is the right way to save dialog's state and EditText's state with selection and text
My code:
public class InputTextDialog extends DialogFragment implements OnClickListener {
static final String DIALOG_TAG = "InputTextDialog";
static EditText input;
String initialText;
InputTextDialogListener inputTextDialogListener = null;
public interface InputTextDialogListener {
void onChangeText(String text);
}
public void setInputTextDialogListener(InputTextDialogListener listener) {
inputTextDialogListener = listener;
}
public void setInitialText(String text) {
initialText = text;
}
#Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setRetainInstance(true);
}
#Override
public void onDestroyView() {
if (getDialog() != null && getRetainInstance())
getDialog().setDismissMessage(null);
super.onDestroyView();
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
input = new EditText(getActivity());
input.setHint("Enter your text");
if (initialText != null) {
input.setText(initialText);
} else {
input.setText("");
}
AlertDialog.Builder adb = new AlertDialog.Builder(getActivity())
.setTitle("Enter your text").setPositiveButton("Apply", this)
.setNegativeButton("Cancel", this).setView(input);
return adb.create();
}
#Override
public void onClick(DialogInterface dialog, int which) {
if (which == Dialog.BUTTON_POSITIVE && inputTextDialogListener != null) {
inputTextDialogListener.onChangeText(input.getText().toString());
}
}
}
Show dialog in activity:
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
InputTextDialog inputDialog = new InputTextDialog();
inputDialog.setInitialText(initialText);
inputDialog.setInputTextDialogListener(new InputTextDialogListener() {
#Override
public void onChangeText(String text) {
resultText = text;
}
});
inputDialog.show(getSupportFragmentManager(), InputTextDialog.DIALOG_TAG);
}
});
