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));
}
});

I can See You are setting "enabled=false" in logout Button could you remove that part or replace with "enabled=true"...I will work if you do so ..please try

Why get login failed while click on login button

If i click on login button my username and password is same as condition but get login failed in Toast Message. Insert correct username and password compiler going to else part. I don't know what is the problem. I am stuck from 4 hours. If you know please solve i am a newbie.

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);

ProgressBar without AsyncTask

I'd like to show the progress bar, generate the computation, then after I do that I'd like the progressbar to disappear and I want to set the textview to the result of my generate result. Yet when I do the below, the progress bar never displays, yet the textview updates appropriately. I originally wanted to do this using AsyncTask but since thats been deprecated I wanted to try a modern method but I'm afraid I can't get it to work. Can anyone see what is wrong?
genResult.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
new Thread(new Runnable() {
#Override
public void run() {
runOnUiThread(new Runnable() {
public void run() {
// do onPreExecute stuff
pb.setVisibility(View.VISIBLE);
}
});
// do your stuff
boolean res = exp.genResult();
long startTime = System.nanoTime();
while(System.nanoTime()-startTime<50000){
}
result.outcomes.add(res);
runOnUiThread(new Runnable() {
public void run() {
// do onPostExecute stuff
pb.setVisibility(View.INVISIBLE);
lastRes.setText(Boolean.toString(res));
}
});
}
}).start();
}
});

The issue is that System.nanoTime() used in the while loop was too quick to complete. When we switch to using System.currentTimeInMillis() we can notice a difference in the delay and thus the spinner shows and hides as expected.

Button disappears when another is clicked

I have an app with 6 buttons that, when clicked, display strings with different lengths:

When I click namebutt, titlebutt or descbutt ( the only ones that have the onClick function at the moment), atbutt just disappears with no errors.
The onClicks:
public void changename(View view){
textView.setText(null);
for(int a=0; a<articles.size(); a++) {
textView.append(articles.get(a).nam);
}
}
public void changetitle(View view){
textView.setText(null);
for(int a=0; a<articles.size(); a++) {
textView.append(articles.get(a).titl);
}
}
public void changedesc(View view){
textView.setText(null);
for(int a=0; a<articles.size(); a++) {
textView.append(articles.get(a).desc);
}
}
This only happens to atbutt
PS: I'm sorry for my choice in naming my buttons

This happens because of this attribute of atbutt:
app:layout_constraintStart_toEndOf="#+id/textView"
which means that the start of atbutt is at the end of the TextView and as the TextView grows it eliminates atbutt's size.
Change to something like this:
<Button
android:id="#+id/atbutt"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="133dp"
android:text="Publish Date"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/urlbutt"
app:layout_constraintTop_toBottomOf="#+id/namebutt" />

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

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