package at.thesis.ticmip.adapter;

import java.util.List;

import android.app.Activity;
import android.content.Context;
import android.support.v4.view.PagerAdapter;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import at.thesis.ticmip.Databaseadapter;
import at.thesis.ticmip.R;


public class TabsPagerAdapter extends PagerAdapter{

      Databaseadapter dbadap;

    String tabs[]={"View","Add","Edit"};
    Activity activity;
    public TabsPagerAdapter(Activity activity){
        this.activity=activity;
    }
    @Override
    public int getCount() {
        return tabs.length;
    }
    @Override
    public boolean isViewFromObject(View view, Object o) {
        return o == view;
    }

    private Context mContext;

    private Object MODE_PRIVATE;
    public TabsPagerAdapter(Context context){
    this.mContext = context;
    }


    @Override
    public CharSequence getPageTitle(int position) {
        return tabs[position];
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        // Inflate a new layout from our resources
        View view=null;

        if(position==0){
          view = activity.getLayoutInflater().inflate(R.layout.activity_admin_vdictionary,container, false);

        }
        if(position==1){
            view = activity.getLayoutInflater().inflate(R.layout.activity_admin_adictionary,container, false);


        }
        if(position==2){
             view = activity.getLayoutInflater().inflate(R.layout.activity_admin_edictionary,container, false);

        }









        // Retrieve a TextView from the inflated View, and update it's text
       // TextView title = (TextView) view.findViewById(R.id.item_title);
        //title.setText(tabs[position]);
         container.addView(view);


        // Return the View
        return view;
    }




















    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
    }






}
