try {
if(json != null){
String text = "<b>Name :</b> "+json.getString("name")+"<br><br><b>Email :</b> "+json.getString("email")+"<br><br><b>Profile link :</b> "+json.getString("link");

You need to call below code on click of button from adapter.
List<String> permissionNeeds = Arrays.asList("publish_actions");
manager = LoginManager.getInstance();
manager.logInWithPublishPermissions(this, permissionNeeds);
manager.registerCallback(callbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
publishImage();
}
@Override
public void onCancel() {
System.out.println("onCancel");
}
@Override
public void onError(FacebookException exception) {
System.out.println("onError");
}
});
}
private void publishImage() {
Bitmap image = BitmapFactory.decodeResource(getResources(),
R.drawable.ic_launcher);
//You need to get bitmap from any source.
SharePhoto photo = new SharePhoto.Builder().setBitmap(image)
.setCaption("Welcome To Facebook Photo Sharing on steroids!")
.build();
SharePhotoContent content = new SharePhotoContent.Builder().addPhoto(
photo).build();
ShareApi.share(content, null);
Toast.makeText(this, "Succsesfully posted on your wall",
Toast.LENGTH_LONG).show();
}
