package com.mekteb;

import android.app.Activity; import android.content.Context; import android.os.Bundle; import android.support.v4.view.PagerAdapter; import android.support.v4.view.ViewPager; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView;

public class Galeri extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_galeri);

    ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
    ImagePagerAdapter adapter = new ImagePagerAdapter();
    viewPager.setAdapter(adapter);
}

  private class ImagePagerAdapter extends PagerAdapter {
        private int[] mImages = new int[] {
            R.drawable.dkvh2,
            R.drawable.dkvh3,
            R.drawable.dkvh6,
            R.drawable.dkvh6,
            R.drawable.dkvh8,
            R.drawable.dkvh9,
            R.drawable.dkvh10,

        };

        @Override
        public int getCount() {
          return mImages.length;
        }

        @Override
        public boolean isViewFromObject(View view, Object object) {
          return view == ((ImageView) object);
        }

        @Override
        public Object instantiateItem(ViewGroup container, int position) {
          Context context = Galeri.this;
          ImageView imageView = new ImageView(context);
          int padding = context.getResources().getDimensionPixelSize(
              R.dimen.padding_large);
          imageView.setPadding(padding, padding, padding, padding);
          imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
          imageView.setImageResource(mImages[position]);
          ((ViewPager) container).addView(imageView, 0);
          return imageView;
        }

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

}
