[Q] New Dev trying to figure out what is probably a simple problem topic

I am getting a NullPointerException after the build but once my phone tries to launch the app. I do not understand where the problem is. Im just learning to code and this app is simply supposed to make a toast pop up Long if the checkbox is clicked and short if it isnt.

Code:

---

package universaltruth.toastee;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.Toast;


public class MainActivity extends ActionBarActivity {

    public CheckBox longToast = (CheckBox) findViewById(R.id.checkbox);
    public EditText editText = (EditText) findViewById(R.id.toastText);
    public int toastLength = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        addListenerOnlongToast();

                }
    public void addListenerOnlongToast(){

        longToast.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                if(((CheckBox) view).isChecked()){
                  toastLength = '1';

                }
            }
        });

    }

    public void toastMessage(View view){

        String message = editText.getText().toString();
        Toast.makeText(getApplicationContext(),message, (toastLength == 0) ? Toast.LENGTH_SHORT : Toast.LENGTH_LONG).show();
    }


    @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);
    }
}
