OUTPUT

You are referring to the R.id.Username component which is the SIGN UP text and you are casting the fields as TextViews instead of EditTexts.
Change your variables to:
EditText Username=(EditText) findViewById(R.id.edittext);
EditText password=(EditText) findViewById(R.id.password);

You are getting the text from the wrong reference, Change the below code to later.
TextView Username=(TextView) findViewById(R.id.Username);
to
TextView Username=(TextView) findViewById(R.id.edittext);

TextInputLayout error message keeps showing up even if the set condition result is false

Screenshot of the problem
This is the code is used for my application:
if (password.isEmpty() && confirmPassword.isEmpty()) {
candidatePassword.setError("Field Cannot Be Empty");
candidateConfirmPassword.setError("Field Cannot Be Empty");
} else if (!password.equals(confirmPassword)) {
candidatePassword.setError("Passwords Do Not Match");
candidateConfirmPassword.setError("Passwords Do Not Match");
} else {
candidatePassword.setError(null);
candidateConfirmPassword.setError(null);
}
Actually, I have 2 versions of this. This one is for the "candidates", and the other is for the "voters". This piece of code works with no issues in the "voters" version of this. Can you point out what I am missing, and what need to do? Thank you!

This is where I assigned my Strings:
private void registerCandidate() {
try {
String email = candidateEmail.getEditText().getText().toString().trim();
String password = candidatePassword.getEditText().getText().toString();
String confirmPassword = candidateConfirmPassword.getEditText().toString();
String fullName = candidateFullName.getEditText().getText().toString().trim();
String yearSection = candidateYearSection.getEditText().getText().toString().trim();
String position = candidatePosition.getEditText().getText().toString().trim();
String achievements = candidateAchievements.getEditText().getText().toString().trim();
String personalQualities = candidatePersonalQualities.getEditText().getText().toString().trim();
String background = candidateBackground.getEditText().getText().toString().trim();

You have a small typo in the code where you get the String values.
It should be:
String password = candidatePassword.getEditText().getText().toString();
String confirmPassword = candidateConfirmPassword.getEditText().getText().toString();

sending data of two fragments to firebase (Fragment wise or in one go)

I have two fragments in one activity. In the first fragment, I have fields like name, email, gender and phone number and by the next button replace with second fragment and on the second fragment, I have a password and confirm password fields. Now I want to send data to firebase fragment-wise or send data of two fragments at one time(by pressing the register button which is on the second fragment).but did not know how to do that

Interface;
interface:
public interface FragmentInterface {
String getName();
String getEmail();
String getPassword();
}
Fragment:
public class FragmentA extend Fragment implements FragmentInterface{}
public class FragmentB extend Fragment implements FragmentInterface{}
xxxActivity:
FragmentInterface fia = (FragmentInterface)FragmentA;
FragmentInterface fib = (FragmentInterface)FragmentB;
get Field:
String name = fia.getName();
String pw = fib.getPassword();
BroadcastReceiver
Global singleton

you have to use bundle in fragment to pass data from one fragment to another
Without Arch. Component...
send data to another fragment
Fragment fragment = new ProductdetailFragment();
FragmentManager manager = getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.frame_main,fragment);
transaction.addToBackStack(null);
transaction.commit();
Bundle bundle = new Bundle();
bundle.putString("product_id","value");
bundle.putString("product_name","value");
bundle.putString("price","value");
bundle.putString("product_desc","value");
bundle.putString("product_image",productmodels.get(position).getProduct_image());
fragment.setArguments(bundle);
get data from the previous fragment. for getting data, you have to use key of apply of the previous fragment.do not mismatch key argument
Bundle bundle = getArguments();
String product_id = bundle.getString("product_id");
String name = bundle.getString("product_name");
String price = bundle.getString("price");
String description = bundle.getString("product_desc");
String imageurl = bundle.getString("product_image");
Second Way if You use Navigation Arch. Component
Bundle bundle = new Bundle();
bundle.putString("amount", amount);
Navigation.findNavController(view).navigate(R.id.confirmationAction, bundle);

I don't get any error. On debugging, it doesn't stop on any of the overrides.

You can set in tow way
First Way:
EditText et_auto_complete_edit_text;
et_auto_complete_edit_text = findViewById(R.id.et_auto_complete_edit_text);
et_auto_complete_edit_text.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void afterTextChanged(Editable s) {
s.toString()
}
});
XML:
<EditText
android:id="#+id/et_auto_complete_edit_text"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_weight="8"
android:background="#color/gray_light_EA"
android:drawableRight="#mipmap/ic_search_new"
android:drawablePadding="#dimen/margin5dp"
android:hint="Search here"
android:inputType="text"
android:maxLines="1"
android:padding="10dp"
android:textColor="#color/black"
android:textColorHint="#color/grey"
android:visibility="visible" />
Second Way :
SearchView search;
search = findViewById(R.id.search);
search.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
fetchData(query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
//collectionProductsListAdapter.getFilter().filter(newText);
return false;
}
});
search.setOnSearchClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
search.setOnCloseListener(new SearchView.OnCloseListener() {
#Override
public boolean onClose() {
return false;
}
});
XML:

Hope this may help you first way is more easy.

Try changing it to EditText

How to make cardview responsive?

]2]2
this is NamazActivity.java In java class i just add cardview click listener and open a toast message. Every click listener shows the iteam ID with simple text
package com.example.shakeelmughal.assanislam;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.CardView;
import android.view.MenuItem;
import android.view.View;
import android.widget.GridLayout;
import android.widget.Toast;
public class NamazActivity extends AppCompatActivity {
GridLayout gridLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_namaz);
//back button
if(getSupportActionBar()!= null)
{
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
gridLayout = findViewById(R.id.gridlayout);
setSingleClick(gridLayout);
}
//function for going back to previous activity
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId() == android.R.id.home)
finish();
return super.onOptionsItemSelected(item);
}
private void setSingleClick(GridLayout gridLayout) {
for (int i = 0; i < gridLayout.getChildCount(); i++) {
CardView cardView = (CardView) gridLayout.getChildAt(i);
final int s = i;
cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(NamazActivity.this, "Item " + s + " Clicked", Toast.LENGTH_SHORT).show();
}
});
}
}
}
