You need to call below code on click of button from adapter.

List permissionNeeds = Arrays.asList("publish_actions");

		manager = LoginManager.getInstance();

		manager.logInWithPublishPermissions(this, permissionNeeds);

		manager.registerCallback(callbackManager,
				new FacebookCallback() {
					@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();

	}
