Clicking button changes wrong Text box.

Question

When the app runs, the "Did you know" text box changes to "Ostriches can run faster..." i.e. the FunFact box doesn't change, the "Did you know" box changes.

Below is my code: package com.treehouse.funfacts;

import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView;

public class FunFacts extends AppCompatActivity { // Declare our View variables private TextView mFactTextView; private Button mShowFactButton;

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

    //Assign the Views from the layout file to the corresponding variables
    mFactTextView = (TextView) findViewById(R.id.factTextView);
    mShowFactButton = (Button) findViewById(R.id.showFactButton);

    View.OnClickListener listener = new View.OnClickListener(){
        @Override
                public void onClick(View v  ){


            //The button was clicked, so update the fact TextView with a new fact
            String fact = "Ostriches can run faster than horses.";
            mFactTextView.setText(fact);

}

}; mShowFactButton.setOnClickListener(listener); } }

Your code looks fine on this page, so it sounds like you assigned the "factTextView" id to the wrong TextView on your "activity_fun_facts.xml" page. Check to see which TextView you assigned that ID to.
