I am fetching data from server and set it into listview. Each Listview item have photo ( url image ) and a text + share button . I have implemented all the code and working perfect.. But can any one help me.. How to implement facebook share intent when click on button of particular listview item.I want to share image and text i ask from a way to the this
and thank you in advance
this is my code "MediaAdapter.java" :
public class MediaAdapter extends ArrayAdapter<Media> {
ArrayList<Media> mediaList;
Context context;
int Resource;
LayoutInflater vi;
ViewHolder holder;
ImageLoader imageLoader;
public MediaAdapter(Context context, int resource, ArrayList<Media> objects) {
super(context, resource, objects);
imageLoader = new ImageLoader(context);
vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Resource = resource;
mediaList = objects;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
// convert view = design
View v = convertView;
v = vi.inflate(Resource, null);
holder = new ViewHolder();
int loader = R.drawable.ic_launcher;
//l url d image
holder.imageview = (ImageView) v.findViewById(R.id.urlImage);
// load image
imageLoader.DisplayImage(mediaList.get(position).getUrl(), loader, holder.imageview );
holder.titre = (TextView) v.findViewById(R.id.titre);
holder.titre.setText(mediaList.get(position).getTitre());
v.setTag(holder);
holder.button = (Button) v.findViewById(R.id.btnOne);
holder.button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Toast.makeText(v.getContext(), "test",Toast.LENGTH_SHORT).show();
}
});
return v;
}
static class ViewHolder {
public ImageView imageview;
public TextView titre;
public Button button;
}
}
Change this in the code ....
First remove this line from the constructor
imageLoader = new ImageLoader(context);
Change it to
ImageLoader imageLoader = ImageLoader.getInstance();
Secondly remove this line from the code :
imageLoader.DisplayImage(mediaList.get(position).getUrl(), loader, holder.imageview );
Change it to
imageLoader.loadImage(mediaList.get(position).getUrl(), new SimpleImageLoadingListener() {
@Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
holder.button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT,mediaList.get(position).getTitre());
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_STREAM, getImageUri(context,loadedImage));
try {
context.startActivity(shareIntent);
} catch (Exception ex) {
Toast.makeText(context, ex.getMessage(),Toast.LENGTH_LONG).show();
}
}
});
}
});
Use this method to transform bitmap to uri:
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(),inImage, "Title", null);
return Uri.parse(path);
}
This will open the the share option for sharing to all the other apps including facebook. If facebook is selected by the user,then the image will be opened in the facebook app (if installed).Let me know if it working for you or not.
this is my new coode it work like a charm
but i have a problem : but i have a problem when i click on share button of the item Number 2 ===== the content of the item number 3 is shared and note the Number 2 and vice-versa ????????????????
holder.button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Uri pictureUri = getLocalBitmapUri(holder.imageview);
if (pictureUri != null) {
// Construct a ShareIntent with link to image
String text = "image : "+mediaList.get(position).getTitre();
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, text);
shareIntent.putExtra(Intent.EXTRA_STREAM, pictureUri);
shareIntent.setType("image/*");
// Launch sharing dialog for image
shareIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(shareIntent);
} else {
// ...sharing failed, handle error
}
