I have a list of images from picasa. I put it in grid view and then on click have the fullscreen image that is done by viewpager. I tried many ways to get bitmap or get imageview from view pager adapter but it is giving null. Please help me, I'm new, this is my first app and I'm confused. This is my code :
package com.example.soha.livingroom;
public class fullimafepager extends Activity implements OnClickListener {
// TouchImageView imgflag;
// BitmapDrawable btmpDr;
private static final String STATE_POSITION = "STATE_POSITION";
// @InjectView(R.id.pager)
LruBitmapCache lreucach;
private PrefManager prefmanger;
private List<String> images = new ArrayList<String>();
private String imageuri;
// Picasa JSON response node keys
// Declare Variables
private ViewPager viewPager;
private ImageAdapter adapter;
private int npostion;
// private Bitmap[] image2;
private int position;
// private im selectedPhoto;
private LinearLayout llSetWallpaper, llDownloadWallpaper;
private Utils utils;
private ProgressBar pbLoader;
private View view;
private Bitmap bitmap;
private ImageView fullImageView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from viewpager_main.xml
prefmanger = new PrefManager(getApplicationContext());
setContentView(R.layout.viewpager_main);
if (getIntent().getExtras() != null) {
this.images = getIntent().getExtras().getStringArrayList("list");
position = getIntent().getIntExtra("postion", 0);
;
// fullImageView= images.get(position);
Log.d("=======", "Data " + images.get(1));
Toast.makeText(this, "the" + images.get(1) + position, Toast.LENGTH_LONG).show();
// Intent i = getIntent();
// image selectedPhoto = (image) getIntent().getSerializableExtra(TAG_SEL_IMAGE);
// System.out.println(images);
}
prefmanger = new PrefManager(getApplicationContext());
// Generate sample data
// flag = new int[] { R.drawable.ico_loader, R.drawable.ico_loader, R.drawable.ico_loader, R.drawable.ico_loader};
// Locate the ViewPager in viewpager_main.xml
viewPager = (ViewPager) findViewById(R.id.pager);
// Pass results to ViewPagerAdapter Class
adapter = new ImageAdapter(fullimafepager.this, images);
// Binds the Adapter to the ViewPager
viewPager.setAdapter(adapter);
// viewPager.setCurrentItem(0);
