Here I have created an ImageAdapter class by extending PagerAdapter
import android.content.Context;
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 ImageAdapter extends PagerAdapter {
private Context mContext;
// Keep all Images in array
public Integer[] mThumbIds = new Integer[] {
R.drawable.a, R.drawable.b,
R.drawable.c, R.drawable.d,
R.drawable.e, R.drawable.f,
R.drawable.g, R.drawable.h,
R.drawable.i, R.drawable.j,
R.drawable.k, R.drawable.l,
R.drawable.m, R.drawable.n,
R.drawable.o, R.drawable.p,
R.drawable.q, R.drawable.r,
R.drawable.t, R.drawable.u,
R.drawable.v
};
// Constructor
public ImageAdapter(Context c){
this.mContext = c;
}
@Override
public int getCount() {
return mThumbIds.length;
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == ((ImageView) object);
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
ImageView imageView = new ImageView(mContext);
imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
imageView.setPadding(8, 8, 8, 8);
imageView.setImageResource(mThumbIds[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
}
This is working fine, with just some redundant warnings, that I don't care about right now.
And here is Fragment class that will display images stored in ImageAdapter class
import android.app.Fragment;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.view.ViewGroup;
import android.widget.GridView;
public class PhotosFragment extends Fragment {
public PhotosFragment(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_photos, container, false);
GridView gridView = (GridView)rootView.findViewById(R.id.grid_view);
gridView.setAdapter(new ImageAdapter(getActivity()));
//GridView gridView = (GridView)rootView.findViewById(R.id.grid_view);
// Instance of ImageAdapter Class
gridView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
// Sending image id to FullScreenActivity
Intent i = new Intent (getActivity().getApplicationContext(), FullImageActivity.class);
// passing array index
i.putExtra("id", position);
startActivity(i);
}
});
return rootView;
}
}
And then here is FullImageActivity class for displaying images in fullscreen
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
public class FullImageActivity extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.full_image);
// get intent data
Intent i = getIntent();
// Selected image id
int position = i.getExtras().getInt("id");
ImageAdapter imageAdapter = new ImageAdapter(this);
ViewPager imageView = (ViewPager) findViewById(R.id.full_image_view);
imageView.addView(imageAdapter.mThumbIds[position]);
}
}
I am getting error in PhotoFragment class-setAdapter in GridView can not be applied to .ImageAdapter
And in FullImageActivity class-addView in ViewGroup can not be applied to .Integer
And here are the layout xml files
full_image.xml
