Not able to click the logout and posy buttons

I have tried checking if any layout is overlapping or not. I have tried adding more space between the button and the border nothing seems to work. I'm not able to see where am I missing out
This is the activity where I'm trying to add setonclicklistenr:
public class addPost extends AppCompatActivity {
ImageView picgal,postt;
EditText descrip,compName;
Button pst,logout;
FirebaseAuth auth;
FirebaseStorage storage;
FirebaseDatabase database;
Uri uri;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_post);
picgal = findViewById(R.id.addpic);
descrip = findViewById(R.id.postDescription);
logout = findViewById(R.id.lgout);
compName = findViewById(R.id.comm);
auth = FirebaseAuth.getInstance();
storage = FirebaseStorage.getInstance();
logout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
auth.signOut();
startActivity(new Intent(addPost.this,postActivity.class));
}

My ImageView disappears when I try to set the image from my Firebase storage

I want to set a picture from my storage by Picasso, however it doesnt work. Initially, there is an icon in my ImageView, but it doesnt show as well after I get to the Activity.
here's code
public class ProfileFragment extends Fragment {
TextView fullNameText, emailText, dateBirthText, phoneText;
TextView addressText;
FloatingActionButton profileEditBtn;
TextView uploadImgBtn;
ImageView profileImg;
String phone, link;
private DatabaseReference dbRef = FirebaseDatabase.getInstance().getReference().child("image");

I ve tried to use Glide instead of picasso, but it didnt work anyways. I'm also pretty sure that my link to file is correct.
realtime db
{
"Users" : {
"123456789" : {
"address" : "",
"date" : "2022-03-27",
"email" : "admin#gmail.com",
"fullName" : "me",
"password" : "qwerty12345",
"phone" : "123456789"
}
},
"image" : "gs://myproj-8984f.appspot.com/images/gachiava.png"
}

Please check whether the Picasso can load with another url by manally adding a url.
Picasso.get().load("your link here").fit().centerCrop().into(profileImg);
And make sure you have added the correct internet permission to Android manifest.

My app is always crashing because of this error. It says:

I'm a beginner who's looking for some code on YouTube, but I can't figure it out.

MaterialEditText is an EditText
public class MaterialEditText extends AppCompatEditText {
it can not contain any widgets. In your layout you have
<com.rengwuxian.materialedittext.MaterialEditText
android:id="#+id/usernameTIL"
android:layout_width="251dp"
android:layout_height="46dp"
android:layout_marginStart="8dp"
android:layout_marginTop="12dp"
android:layout_marginEnd="8dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.527"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/textView">
<com.rengwuxian.materialedittext.MaterialEditText
android:layout_width="268dp"
android:layout_height="36dp"
android:hint="username" />
</com.rengwuxian.materialedittext.MaterialEditText>
a MaterialEditText containing another MaterialEditText, which is causing your app to crash for ClassCastException

According to this library's sample code, you must cast your MaterialEditText to EditTextlike this:
usernameTIL = (EditText) findViewById(R.id.usernameTIL);
passwordTIL = (EditText) findViewById(R.id.passwordTIL2);

Android actionbar/toolbar disappears after writing to edittext [duplicate]

This question already has answers here:
Android Toolbar moves up when keyboard appears

Closed 4 years ago.
I'm stuck at this. I have an app where I have several pages made as fragments. Every page is good except the last one where when I tap on editText, action bar disappears and when I unfocus it, action bar didn't show up back.
I've tried changing appTheme to all kind of themes but they didn't change anything, most of them forced app to crash.
Here is my layout of that page

You can try to set windowSoftInputMode in manifest. Choose which is most suitable for you.

How can call to refresh my fragment class in another method (I Tried all the solution on stackoverflow)

I have a void method synchronizeNum(String String String) Which will be trigger in onViewCreated , This Line.
new DisDepartmentSender(myView.getContext(), urlAddress, accountEmail, departmentName).execute();
It will get data from database and finally pass back and set the data into this method synchronizeNum (String String String).After i set the data i wish to display it using TextView. I think the only way is execute again onViewCreated method, since we cannot setText inside synchronizeNum method.I have tried many detach and attach method inside the method but the problem is it get NullPointer i donno how to solve i have been looking around for 1 day just for this little problem. I need you guys help please.

I recommend to create an interface for updating data.
public interface SynchronizeCallback {
void synchronizeNum(String num1room1, String num2room2, String num3room3);
}
Your fragment should implement this interface.
Also set the text to the TextViews inside synchronizeNum():
num_1.setText(num1);
num_2.setText(num1);
num_3.setText(num1);
room_1.setText(room1);
room_2.setText(room2);
room_3.setText(room3);
Pass the interface to your task when you create it:
new DisDepartmentSender(myView.getContext(), urlAddress, accountEmail, departmentName, this).execute();
In onPostExecute of your AsyncTask call
syncronizeCallback.updateValues(newNum1room1, newNum2room2, newNum3room3);
Then you should see the new data.
