App crashes when ImageView is clicked

Question

Just started coding, be easy on me.

Followed the instructions outlined HERE but changed the button onClick to an ImageView onClick (I have an image that once clicked, moves to another activity) but it doesn't seem to work. I'm wondering if I'm missing something. If anyone could help me out, that would be awesome :)

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ImageView;

public class MainActivity extends AppCompatActivity {

    ImageView hotel; **//the image that gets clicked. Don't know if i need
 //this in the code or not. nothing seems to point to it

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setTitle(null);
    }

    public void goToHotelWebView (View view) {
        Intent intent = new Intent(this, hotelwebview.class);
        startActivity(intent); **//The code that I added in from the tutorial**

    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);


        }
    }

And on my .xml page, the image has onClick set to goToHotelWebView.

Thanks for your help!

EDIT= HERE IS THE ERROR IN LOGCAT... Reading it, it looks like a problem with the action bar design but I created a new activity with a blank slate and the app still crashes.

did you declare 'hotelwebview' in your AndroidManifest.xml ? — diegoveloper, Nov 23 '17 at 23:06
Yeah. I created the new activity by right clicking on the app folder and selecting "add new activity" so it automatically declared hotelwebview in AndroidManifest.xml — wesdaco, Nov 23 '17 at 23:16
Please read [Unfortunately MyApp has stopped. How can I solve this?](https://stackoverflow.com/q/23353173/295004) — Morrison Chang, Nov 23 '17 at 23:19
Sorry for the long code here, just pasted everything from the logcat: — wesdaco, Nov 23 '17 at 23:22
I have edited the post to show the error @diegoveloper. Thank you! — wesdaco, Nov 23 '17 at 23:27
as you can see the problem is your activity called "hotelwebview" , put the code com.example.wes.tripedia2/com.example.wes.tripedia2.hotelwebview}: java.lang.IllegalStateException — diegoveloper, Nov 23 '17 at 23:28

ERROR DESCRIPTION : This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

Check your AndroidManifest file and check the theme for your activity "hotelwebview".

  <activity
            android:name=".hotelwebview"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:theme="@style/AppTheme"/>

Modify your theme like this :

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

I learned to check the logcat to find out my errors. The problem appears to be with my toolbar — wesdaco, Nov 23 '17 at 23:42
