Looking for some insight on intializing the getAnswerButton variable using the findViewByID() method.

'''Java package com.example.crystal.ball;

import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView;

public class MainActivity extends Activity {

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

    // Declare our view variables
    TextView answerLabel = (TextView) findViewById(R.id.textView1);     
    Button getAnswerButton = (Button) findViewById(R.id.textView1);

'''

Button getAnswerButton = (Button) findViewById(R.id.button1);
