}

}
but when it returned activity AddProductActivity,the images did not appear in gridview ,if i clicked the editorText to active the keyboard,the images appearing in the gridview. So i am puzzled,waiting for some suggestions, thanks!
image url :http://i61.tinypic.com/2ch9onq.png
actived keyboard image appearing: http://i61.tinypic.com/2l8uumc.png
if i used this getView() method in AddProductActivity,it works fine.
#Override
public View getView(final int position, View convertView, ViewGroup
parent)
{
if (convertView == null){
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(245, 150));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
}
else {
imageView = (ImageView) convertView;
}
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inJustDecodeBounds = false ;
bmOptions.inSampleSize = 4;
bmOptions.inPurgeable = true ;
Bitmap bitmap = BitmapFactory.decodeFile(selectImageUrls.get(position), bmOptions);
imageView.setImageBitmap(bitmap);
return imageView;
}
but it does not smooth when it transfored the imageurls back to AddProductActivity.

Try to replace adapter code.
public class SelectImageAdapter extends BaseAdapter {
Context mContext;
ViewHolder holder;
public SelectImageAdapter(Context context, ArrayList<String> imageList) {
// TODO Auto-generated constructor stub

holder.spinner = (ProgressBar)convertView.findViewById(R.id.select_image_loading);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
//final ViewAnimator animator = (ViewAnimator)convertView.findViewById(R.id.animator);
imageLoader.displayImage("file://" + selectImageUrls.get(position),holder.imageView,

I believe what is missing in the code is a call to notifyDataSetChanged() after the images are loaded (in onLoadingComplete() callback of the listener).
The way the above code is written, if notifyDataSetChanged() is called in onLoadingComplete(), it will solve the problem that you have.
However, calling notifyDataSetChanged() every time in that callback method, may degrade the performance significantly. The more images you have, the more the performance may drop.
If you do observe performance drop by doing the above, to solve it, I would suggest using an image refresh helper mechanism. This way you can either call notifyDataSetChanged():
after n images have been loaded
or after every t seconds has passed
I hope the information above helps you.

holder.placementCustomLinear is the custom leaner-layout need to be make it invisible

After some research i have solved my problem by adding a parent layout in the the xml and adding the some logic in the adapter class like
if (Util.ROLE.equalsIgnoreCase("admin")) {
holder.placementCustomLinear.setVisibility(View.VISIBLE);
}else
if(isPublic==0){
Log.i("inside if ", ""+isPublic);
Log.i("custom disply", custom);
int[] arry= stringToInteger(custom);
Log.i("numbers to ccheck ", ""+(arry));
for (int i = 0; i < arry.length; i++) {
if(custom.contains(Util.USER_ID)){
Log.i("true checked ", "inside");
holder.placementCustomLinear.setVisibility(View.VISIBLE);
notifyDataSetChanged();
}else{
holder.placementCustomLinear.setVisibility(View.GONE);
notifyDataSetChanged();
}
}
if(isPublic==0&&Util.USER_ID.contains(custom)){
holder.placementCustomLinear.setVisibility(View.VISIBLE);
notifyDataSetChanged();
}
}
else{
Log.i("else block ",""+isPublic);
if(isPublic==1)
holder.placementCustomLinear.setVisibility(View.VISIBLE);
notifyDataSetChanged();

my problem is solved thanks for the people who have give some suggestion

notifyDataSetChanged() doesn't work with my adapter for gridview

I have a GridView and adapter for GridView (BasketAdapter extends BaseAdapter).
I load data in GridView from sharedpref file.
After I change data, I resave sharedpref file with data and call notifyDataSetChanged().
But notifyDataSetChanged() doesn't work unfortunately.
If I create new adapter and set it to my GridView, it works.

Your convertView isn't null in case the View is recycled, so your getView() should be something like this:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if(view == null)
{
LayoutInflater inflater = getLayoutInflater(null);
view = inflater.inflate(R.layout.right_panel_fragment_catalog_grid_item, parent, false);
}
CatalogItem item = getItem(position);
((TextView)view.findViewById(R.id.tvCatalogItemBasketName)).setText(item.name + " / " + item.code);
Double gPrice = Double.valueOf(item.price) * Double.valueOf(item.count);
((TextView)view.findViewById(R.id.tvCatalogItemBasketCount)).setText(String.valueOf(item.count));
((TextView)view.findViewById(R.id.tvCatalogItemBasketGeneralPrice)).setText(String.valueOf(gPrice));
((TextView)view.findViewById(R.id.tvCatalogItemBasketDescription)).setText(item.description);
final ImageView imgView = (ImageView)view.findViewById(R.id.ivCatalogItemBasketImage);
String strURL = "http://myproject.ua/images/stock/" + item.folder + "/" + item.images + "_800x600.jpg";
ImageLoaderConfiguration config = ImageHelper.ImageConfig(getActivity().getApplicationContext());
DisplayImageOptions options = ImageHelper.ImageOptions();
ImageLoader imageLoader = ImageLoader.getInstance();
imageLoader.init(config);
final ProgressBar pImgDialog = (ProgressBar)view.findViewById(R.id.pbImage);
imageLoader.displayImage(strURL, imgView, options, new ImageLoadingListener() {
#Override
public void onLoadingStarted(String imageUri, View view) {
pImgDialog.setVisibility(View.VISIBLE);
imgView.setVisibility(View.GONE);
}
#Override
public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
pImgDialog.setVisibility(View.GONE);
imgView.setVisibility(View.VISIBLE);
}
#Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
pImgDialog.setVisibility(View.GONE);
imgView.setVisibility(View.VISIBLE);
}
#Override
public void onLoadingCancelled(String imageUri, View view) {
pImgDialog.setVisibility(View.GONE);
imgView.setVisibility(View.VISIBLE);
}
});
view.setTag(item.catalog_id);
return view;
}
and since you have your own ArrayList inside your adapter, you have to update this one as well. Just add this method to your BasketAdapter:
public void changeModelList(List<CatalogItem> models) {
this.data = models;
notifyDataSetChanged();
}
and use it instead of notifyDataSetChanged().
it's not tested, but i think this is your problem.

Share Intent on click

I have a ViewPager with an ImageView and I want to make it such that when someone clicks on the image they can share it with a share Intent.
I'm not sure how to do this. Below is my code.
If someone can show me how to do this that would be great!
public class ImagePagerActivity extends BaseActivity {
private ViewPager pager;
private TextView mSelected;
private String[] mLocations;
private DisplayImageOptions options;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ac_image_pager);
mSelected = (TextView)findViewById(R.id.text);
mLocations = getResources().getStringArray(R.array.locations);
Context context = getSupportActionBar().getThemedContext();
ArrayAdapter<CharSequence> list = ArrayAdapter.createFromResource(context, R.array.locations, R.layout.sherlock_spinner_item);
list.setDropDownViewResource(R.layout.sherlock_spinner_dropdown_item);
getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
getSupportActionBar().setListNavigationCallbacks(list, this);
getSupportActionBar().setSelectedNavigationItem(1);
Bundle bundle = getIntent().getExtras();
String[] imageUrls = bundle.getStringArray(Extra.IMAGES);
int pagerPosition = bundle.getInt(Extra.IMAGE_POSITION, 0);
options = new DisplayImageOptions.Builder()
.showImageForEmptyUri(R.drawable.image_for_empty_url)
.cacheOnDisc()
.imageScaleType(ImageScaleType.EXACT)
.build();
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(new ImagePagerAdapter(imageUrls));
pager.setCurrentItem(pagerPosition);
}
#Override
protected void onStop() {
imageLoader.stop();
super.onStop();
}
private class ImagePagerAdapter extends PagerAdapter {
private String[] images;
private LayoutInflater inflater;
ImagePagerAdapter(String[] images) {
this.images = images;
inflater = getLayoutInflater();
}
#Override
public void destroyItem(View container, int position, Object object) {
((ViewPager) container).removeView((View) object);
}
#Override
public void finishUpdate(View container) {
}
#Override
public int getCount() {
return images.length;
}
#Override
public Object instantiateItem(View view, int position) {
final FrameLayout imageLayout = (FrameLayout) inflater.inflate(R.layout.item_pager_image, null);
final ImageView imageView = (ImageView) imageLayout.findViewById(R.id.image);
final ProgressBar spinner = (ProgressBar) imageLayout.findViewById(R.id.loading);
imageLoader.displayImage(images[position], imageView, options, new ImageLoadingListener() {
#Override
public void onLoadingStarted() {
spinner.setVisibility(View.VISIBLE);
}
#Override
public void onLoadingFailed(FailReason failReason) {
String message = null;
switch (failReason) {
case IO_ERROR:

break;

break;
}
Toast.makeText(ImagePagerActivity.this, message, Toast.LENGTH_SHORT).show();
spinner.setVisibility(View.GONE);
imageView.setImageResource(android.R.drawable.ic_delete);
}
#Override
public void onLoadingComplete() {
spinner.setVisibility(View.GONE);
Animation anim = AnimationUtils.loadAnimation(ImagePagerActivity.this, R.anim.fade_in);
imageView.setAnimation(anim);
anim.start();
}
#Override
public void onLoadingCancelled() {
// Do nothing
}
});
((ViewPager) view).addView(imageLayout, 0);
return imageLayout;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view.equals(object);
}
#Override
public void restoreState(Parcelable state, ClassLoader loader) {
}
#Override
public Parcelable saveState() {
return null;
}
#Override
public void startUpdate(View container) {

}
#Override
public boolean onNavigationItemSelected(int itemPosition, long itemId) {
if (itemPosition == 0){
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);
}
getSupportActionBar().setSelectedNavigationItem(1);
return true;
}
}

Add this code in your object instantiateItem method
imageView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/jpeg");
intent.putExtra(Intent.EXTRA_STREAM, [image URI]);
startActivity(Intent.createChooser(intent, "Share image with"));
}
}
This is updated version of u'r code
public class ImagePagerActivity extends BaseActivity {
private ViewPager pager;
private TextView mSelected;
private String[] mLocations;
private DisplayImageOptions options;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
