The issue is when I don't put any value into the firstEditText or secondEditText or both of them and click on any button then the app crashes and a pop up shows "myapp keeps stopping".
I cannot get the text and am unsure of why the app keeps crashing.
you have defined your Edit texts in the first activity with id's named
edtPhone
edtMessage
but there was no edtPhone or edtMessage in your xml.
this issue also repeats in your second activity
you have defined txtPhone and txtMessage
but again there are no such ids in your second activity XML.
keep in mind that these might not be the whole problem as you didn't post any log for the errors. but if there were anything else, ask and we'll help you
Here I am trying to take user input and display output in a Text View, but checkgen and checkuser is returning -1 despite of selecting them and also both the radio buttons are getting selected not any one of them, I want to display all the details entered in the text view.

How can I scroll in my Android app?
I already tried Scrollview but it doesn`t work.
So this is my MainActivity:
package com.example.myapplication2;
import android.content.DialogInterface;
import android.content.Intent;
import android.icu.text.IDNA;
import android.nfc.Tag;
import android.os.PersistableBundle;
import android.support.annotation.NonNull;
import android.support.design.widget.BottomNavigationView;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
import static com.example.myapplication2.R.id.*;
public class MainActivity extends AppCompatActivity implements BottomNavigationView.OnNavigationItemSelectedListener {
private boolean loadFragment(Fragment fragment){
if(fragment!=null){
getSupportFragmentManager()
.beginTransaction()
.replace(fragment_container, fragment)
.commit();
return true;
}
return false;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomNavigationView navigation = findViewById(R.id.bottomnav);
navigation.setOnNavigationItemSelectedListener(this);
getSupportFragmentManager().beginTransaction().replace(fragment_container, new Home_Screen()).commit();
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
Fragment fragment = null;
switch(menuItem.getItemId()){
case kontakt:
break;
case Termine:
fragment = new TermineFragment();
break;
case wilkommen:
fragment = new Home_Screen();
break;
}
return loadFragment(fragment);
}
}

What should I do? I want these Cardviews in my Scrollview.
Replace your XML layout code with the below. Also, be notified, there seems to be an awkward amount of topMargin between your two cards, not sure if that's intended or not but as of now, there is huge gap between your two cards :

Use ScrollView in place of RelativeLayout. Add a LinearLayout with vertical orientation before the first TextView and close the LinearLayout after the CardView.
The app is supposed to call one screen from another and use the other screen's layout components. Whenever I try to call a component, such as ImageButton, it says that member id is unknown, I told my teacher and he says that it shouldn't happen. I have tried renaming the components and even made a new project.
How can I fix it?
the error is in R.id

This is my Activity
RelativeLayout custom_RelativeLayout = (RelativeLayout)findViewById(R.id.actionbar_relativelayout);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM );
getSupportActionBar().setCustomView(R.layout.custom_actionbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayShowCustomEnabled(true);
getSupportActionBar().setDisplayUseLogoEnabled(false);
getSupportActionBar().setDisplayShowHomeEnabled(false);
getSupportActionBar().setBackgroundDrawable(
getApplicationContext().getResources().getDrawable(
R.drawable.drawable_actionbar_back));
getSupportActionBar().setCustomView(R.layout.custom_actionbar);
I want to its occupy whole space of action bar but it does not occupy i also read many answers on stackoverflow but didn't work.

If you want to get the height of native action bar then use ?android:attr/actionBarSize in XML.
Now your XML will look like:
