Cannot resolve symbol Toast or Button. Cannot resolve method setOnClickListener.

I am starting chapter 2 of the Build an Interactive Story App.

I am getting resolve symbol and method errors.

Here is my code for the MainActivity.java file:

package teamtreehouse.com.interactivestory;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.EditText;


public class MainActivity extends Activity {

    private EditText mNameField;
    private Button mStartButton;

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

        mNameField = (EditText)findViewById(R.id.nameEditText);
        mStartButton = (Button)findViewById(R.id.startButton);

        mStartButton.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                String name = mNameField.getText().toString();
                Toast.makeText(MainActivity.this, name, Toast.LENGTH_LONG).show();
            }
        });
    }
}

I solved it.

I needed to add these widgets and content elements to my import statement at the top of the java file.

So now my import statement looks like:

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.EditText;
import android.content.Intent;
import android.widget.Button;

And it works now!
