Calling Textview values using Android app

I am doing a Android app where I want to show the travels contact numbers. Here is the code:

App2Activity.java

package com.example.android;

import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;

public class App2Activity extends Activity {

    Button button;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main2);
    }
}

AppActivity.java

package com.example.android;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Button;
import android.view.View;
import android.view.View.OnClickListener;

public class AppActivity extends Activity {
    Button button;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        addListenerOnButton();
    }


public void addListenerOnButton() {
    final Context context = this;
    button = (Button) findViewById(R.id.button1);
    button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            Intent intent = new Intent(context, App2Activity.class);
            Intent intent = new Intent(Intent.ACTION_CALL);
                        startActivity(intent);   
        }
    });
}

}

            <intent-filter >
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:label="@string/app_name"
            android:name=".App2Activity" >
        </activity>
    </application>

</manifest>

When clicked on "Travels and Holidays" button, it shows the 3 travels names with their contact number. I want to call that travels through the app. So if I click on particular travels, it should redirect to the call of that number. Where am I going wrong? Please help. Thanks in advance.
