Add more than one element to set content view

i have a app set up which loads a website into the app which works fine, when i try to add another element to the content view the app crashes without a error, How can i add more than one element to my set content view? ive tried it with frame layout and more but they all dont seem to work.
Here is my code

webSettings.setJavaScriptEnabled(true);
myWebView.loadUrl("https://www.fiercepc.co.uk");
setContentView(myWebView);
setContentView(button);
}
}

your app crashes because your are trying to set button view and webView as the root layout, don't do that, inflate or bind the root of your layout with ActivityMainBinding
do it like this :
public class MainActivity extends AppCompatActivity {
private ActivityMainBinding binding;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
bindnig = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
LinearLayout screenLayout = new LinearLayout(this);
screenLayout.setOrientation(LinearLayout.VERTICAL);
Button button = (Button) findViewById(R.id.button);
WebView myWebView = new WebView(getApplicationContext());
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.loadUrl("https://www.fiercepc.co.uk");
}
}

WebView will not load when in another layout, but works fine in main

I am working on an android project that reqires a home screen that I just have image buttons on for the time being, but would like to access different layouts, it access the different layouts just fine, but when using the same code for webview, webview refuses to load and just displays a blank screen, the same code worked fine on the main activity, but is giving me trouble now and im not sure where to go from here, I only have an image on the second activity as a sanity check that my buttons were going to the right places
Main Activity
package com.example.bsc_group;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.ImageButton;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
getSupportActionBar().hide();
setContentView(R.layout.activity_main);
ImageButton foodButton = (ImageButton) findViewById(R.id.imageButtonFood);
foodButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
}
});
ImageButton techButton = (ImageButton) findViewById(R.id.imageButtonTech);
techButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
}
});
ImageButton calendarButton = (ImageButton) findViewById(R.id.imageButtonCalendar);
calendarButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.bcs_calendar_widget);
}
});
}
}
Second activity
package com.example.bsc_group;
import androidx.appcompat.app.AppCompatActivity;

#Override

super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
getSupportActionBar().hide();
webView = findViewById(R.id.webviewWidget);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl("https://google.com");
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
setContentView(R.layout.bcs_calendar_widget);
{
//Spinner spinnerBcsListings = findViewById(R.id.spinner_bcs_group);
//ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.bcs_group_listings, android.R.layout.simple_spinner_item);
//adapter.setDropDownViewResource(android.R.layout.simple_spinner_item);

}
}
#Override
public void onBackPressed() {
if (webView.canGoBack()){
webView.goBack();
}else {
setContentView(R.layout.activity_main);}
}
}
XML file for second activity
<?xml version="1.0" encoding="utf-8"?>

The issue is that you are not opening the activity. Only giving a context view without executing the code. This bad. Whenever you want to go to another activity, use this code:
Intent intent = new Intent(this, OtherActivity.class);
startActivity(intent);
Also in the onBackpressed I see that you are just doing setContentView. Don't do that. Use this instead:
finish();

Webview app turns off after Splash Screen Android Studio

I am creating a Webview application and I need to add Splash Screen at load time.
I tried different ways, with this it "starts", but after Splash Screen it just turns off. What can I do to make the application show Splash Screen and open correctly?
SplashScreen.java:
package com.example.evrika;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
public class SplashScreen extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
startActivity(new Intent(SplashScreen.this,MainActivity.class));
finish();
}
},1000);
}
}
activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<WebView
android:id="#+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</androidx.constraintlayout.widget.ConstraintLayout>
MainActivity.java:
package com.example.evrika;
import androidx.appcompat.app.AppCompatActivity;
import android.annotation.TargetApi;
import android.os.Build;
import android.os.Bundle;
import android.webkit.WebResourceRequest;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().hide();
WebView webView = findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(false);
webView.getSettings().setSupportZoom(false);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.getSettings().setAllowFileAccess(true);
webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
webView.loadUrl("https://evrikaspace.ru/");
WebViewClient webViewClient = new WebViewClient() {
#SuppressWarnings("deprecation") #Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#TargetApi(Build.VERSION_CODES.N) #Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
view.loadUrl(request.getUrl().toString());
return true;
}
};
webView.setWebViewClient(webViewClient);
}
}

Probably this line is making noise getSupportActionBar().hide();

Android Studio - findViewById() causing error [duplicate]

This question already has answers here:
Null pointer Exception - findViewById()
(12 answers)
Closed 2 years ago.
This is my first post so apologies if I get any of the formalities wrong...
Before anyone tells me the question is invalid, every solution I have looked at says I should have:
setContentView(R.layout.whateverViewImCurrentlyTryingToFocus)
before I call a
findViewById()
When I debug my application it is crashing when I set up an onClickListener for my button (R.id.sign_in_button), line 75.
So I decided to check what findViewById() was returning so I run the code
Button button = findViewById(R.id.sign_in_button)
This caused the same error. I think it it returning null but not entirely sure.
Activitylogin.xml is the first layout to be loaded, and then the mainactivity.xml is supposed to launch after a firebase sign-in.

If you need anymore information please let me know and I will provide. I can't wrap my head around this issue and really hope some android studio experts can explain it to me as if I'm a idiot because I would love to learn!
I am attempting to fix this as soon as I wake up, because I never quit!

All,
Thank you for your replies,
I woke up this morning and after looking at the logcat as suggested by #Frank van puffelen, I noticed that the error was a nullPointerException on a textView. This was weird becuase there was no textView in my loginActivity. Upon further inspection, I hadn't created the username and the email textView in my main_activity.xml (Problem with late night coding, I should have spotted that). So this was returning a nullPointerException simply because it didn't exist. I added the username, email and logout button to the xml and it works.
Thanks for the help, not entirely sure how to close this thread (this is my first post), apologies for wasting time but I was a little desperate.
