- Swipe, um das nächste Fragment mit einem button-Klick

Hier ist mein code:

FirstView.java

import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;

public class FirstView extends Fragment
{
    private TextView firstText;
    private Button btn;

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {


        View view = inflater.inflate(R.layout.fragment_view1,container,false);


        firstText = (TextView)view.findViewById(R.id.viewOneText);
        btn = (Button)view.findViewById(R.id.viewOneBtn);

        btn.setOnClickListener(new ButtonEvent());
        return view;

    }

    private class ButtonEvent implements OnClickListener
    {

        @Override
        public void onClick(View v) {
            //TODO Auto-generated method stub
            new SecondView();

        }

    }
}

SecondView.java

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;

public class SecondView extends Fragment
{
    private TextView secondText;
    private Button secondViewBtn;

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {


        View view = inflater.inflate(R.layout.fragment_view2,container,false);


        secondText = (TextView)view.findViewById(R.id.secondViewText);
        secondViewBtn = (Button)view.findViewById(R.id.secondViewBtn);

        secondViewBtn.setOnClickListener(new ButtonEvent());
        return view;

    }

    private class ButtonEvent implements OnClickListener
    {

        @Override
        public void onClick(View v) {
            //TODO Auto-generated method stub
            secondText.setText("Second View Text changed");

        }

    }
}

MainActivity.java

import android.os.Bundle;
import android.app.Activity;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.Menu;

public class MainActivity extends  FragmentActivity  {

    private ViewPager viewPager;
    private MyAdapter pageAdapter;
    private static final int ITEMS = 2;

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

        viewPager = (ViewPager)findViewById(R.id.pager);
        pageAdapter = new MyAdapter(getSupportFragmentManager());
        viewPager.setAdapter(pageAdapter);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        //Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    public static class MyAdapter extends FragmentPagerAdapter {


        public MyAdapter(FragmentManager fragmentManager) {
            super(fragmentManager);
        }

        @Override
        public int getCount() {
            return ITEMS;
        }

        @Override
        public Fragment getItem(int position) {
            if(position==0)
            {
                return new FirstView();
            }
            else
            {
                return new SecondView();
            }
        }
    }

}

In diesem code, wenn ich auf die Button im FirstView, ich brauche zu bewegen, um die SecondView. Ich habe versucht, mit Intents aber denke, es ist falsch. Dies ist aktuell mit der Swipe-Funktion, da der ViewPager brauche ich, um diese zu bewegen, um die SecondView wenn der button angeklickt wird, mit der gleichen swipe-Funktionalität.
