import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;


public class Main2Activity extends AppCompatActivity {
ViewPager viewPager;
scrAdapter adapter;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    viewPager = (ViewPager)findViewById(R.id.vp);

    adapter = new scrAdapter(this);

    viewPager.setAdapter(adapter);
      }

private int image_source [] = {R.drawable.aa,
        R.drawable.bb,
        R.drawable.cc,
        R.drawable.dd,
        R.drawable.ee,

        R.drawable.z

};

private Context ctx;
private LayoutInflater layoutInflater;


public scrAdapter (Context ctx){
    this.ctx= ctx;

}

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

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

@Override
public Object instantiateItem(ViewGroup container, int position) {
    layoutInflater = (LayoutInflater)ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View item = layoutInflater.inflate(R.layout.scrshots,container,false);
    ImageView img = item.findViewById(imageView);
    img.setImageResource(image_source[position]);
    img.setLongClickable(true);
    img.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View view) {
            Intent intent = new Intent();
            intent.setAction(Intent.ACTION_SEND);
            intent.putExtra(Intent.EXTRA_STREAM,"");
            intent.setType("image/jpeg");
            ctx.startActivity(intent);
            return true;
        }
    });

    container.addView(item);
    return item;


}

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

}

Answer 1

You didn't put anything to send via intent. You have to put the image in temporary path so other applications can access it and send uri path via intent. Check this answer for details.
