1,706 PointsCannot resolve "factTextView"
I copied the code as it is shown in the video, but I get this error:
Cannot resolve "factTextView". in
factTextView = findViewById(R.id.factTextView);
Here's my java code:
package com.example.admin.facts;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Button;
import android.widget.TextView;
public class funnestActivity extends AppCompatActivity {
private TextView factTextView;
private Button factButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_funnest);
factTextView = findViewById(R.id.factTextView);
}
}
and here is my xml:
<?xml version="1.0" encoding="utf-8"?>

I've tried cleaning and rebuilding the project and checking the R resources, but nothing seems to work.
I need help fast, no one has answered my previous question for over a week and I can't continue the Android track because of this.

529 PointsFirst factTextView id doesn't exist mate you have to put it in the id property of a TextView
```xml
<TextView
android:id="@+id/factTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Did you know?"
android:textColor="#84ffffff"
android:textSize="24dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintHorizontal_bias="0.059"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.029" />
```
Secondly cast :
```java
factTextView = (TextView)findViewById(R.id.factTextView);
```
