2,796 PointsBug in my code
Good afternoon coders. I was following along with this video. When I finished a whole bunch of errors popped up. I've tried everything I know and can't figure it out. Your help will be appreciated
package com.teamtreehouse.funfacts;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.util.Random;
public class FunFactsActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fun_facts);
// Declare our View variables and assign the the Views from the layout file
final TextView factLabel = (TextView) findViewById(R.id.factTextView);
Button showFactButton = (Button) findViewById(R.id.showFactButton);
View.OnClickListener listener = new View.OnClickListener() {
@Override
public void onClick(View view) {
// The button was clicked, so update the fact label with a new fact
String fact = "";
// Randomly select a fact
Random randomGenerator = new Random(); // Construct a new Random number generator
int randomNumber = randomGenerator.nextInt(3);
fact = randomNumber + "";
// Update the label with our dynamic fact
if (randomNumber == 0) {
// set fact equal to ants fact
fact = "Ants stretch when they wake up in the morning.";
} else if (randomNumber == 1) {
fact = "Ostriches can run faster than horses.";
} else if (randomNumber == 2) {
fact = "Olympic gold medals are actually made mostly of silver.";
} else {
fact = "Sorry, there was an error!";
}
factLabel.setText(fact);
}
};
showFactButton.setOnClickListener(listener);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.fun_facts, 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();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
The errors were cannot resolve symbol 'factTextView' cannot resolve symbol'showFactButton'
Again your help is appreciated.
