210 PointsMake sure to use "findViewById" to declare the button.
I really don't know how to solve this problem. I've been stuck for 3 days in a row, please help me!!
This is the code:
'''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.button1);
Button getAnswerButton;
}
}

It looks like you are trying to assign a button (R.id.button1) to a TextView object. you need to put ->
TextView answerLabel = (TextView) findViewById(R.id.textView1);
Button getAnswerButton = (Button) findViewById(R.id.button1);
Thats providing your textView and button are named textView1 & button1 - you can check them in your activity_main.xml file or use content assist :)

2,611 PointsNo worries, not 100% sure as to why that didn't work. What is the error your getting? Also could you post the code in your activity_main.xml
Yonatan Rojas
210 PointsThe same, it says Make sure to use "findViewById" to declare the button. Where is my activity_main.xml?
Jason Thorn
2,611 Pointsit's under res/layout/
Should be something like activity_main_list.xml. Also is the line -
Button answerButton = (Button) findViewById(R.id.button1);
underlined in red?
Yonatan Rojas
210 PointsNo, it not underlined in red my friend
