//Facebook client
private CallbackManager fb_callbackManager;

@Override

super.onCreate(savedInstanceState);
//Initialize Facebook API
FacebookSdk.sdkInitialize(getApplicationContext());
fb_callbackManager = CallbackManager.Factory.create();

}
return super.onOptionsItemSelected(item);
}
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.imageView:
loadImage();
break;
case R.id.button:
share();
break;
}
}
private void loadImage(){
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
photoPickerIntent.putExtra("crop", "true");
photoPickerIntent.putExtra("scale", true);
photoPickerIntent.putExtra("scaleUpIfNeeded", true);
photoPickerIntent.putExtra("max-width", 170);
photoPickerIntent.putExtra("max-height", 160);
photoPickerIntent.putExtra("aspectX", 1);
photoPickerIntent.putExtra("aspectY",1);
startActivityForResult(photoPickerIntent, ACTION_PICK_IMAGE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == ACTION_PICK_IMAGE) {
if (resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
//get the cropped bitmap
Bitmap thePic = extras.getParcelable("data");
imageView.setImageBitmap(thePic);
}
}
}
protected void share(){
String shareText = editText.getText().toString();
ShareDialog shareDialog = new ShareDialog(this);
if (ShareDialog.canShow(SharePhotoContent.class)) {
shareDialog.registerCallback(fb_callbackManager, new FacebookCallback<Sharer.Result>() {
@Override
public void onSuccess(Sharer.Result result) {
Toast.makeText(MainActivity.this, "Share Success", Toast.LENGTH_SHORT).show();
Log.d("DEBUG", "SHARE SUCCESS");
}
@Override
public void onCancel() {
Toast.makeText(MainActivity.this, "Share Cancelled", Toast.LENGTH_SHORT).show();
Log.d("DEBUG", "SHARE CACELLED");
}
@Override
public void onError(FacebookException exception) {
Toast.makeText(MainActivity.this, exception.getMessage(), Toast.LENGTH_LONG).show();
Log.e("DEBUG", "Share: " + exception.getMessage());
exception.printStackTrace();
}
});
SharePhoto photo = new SharePhoto.Builder()
.setBitmap(((BitmapDrawable) imageView.getDrawable()).getBitmap())
.build();
SharePhotoContent content = new SharePhotoContent.Builder()
.addPhoto(photo)
.build();
shareDialog.show(content);
}
}
}

Rien n'est montré, ou au moins pas visible, parce que je dois frapper en arrière pour être en mesure d'interagir avec ma reprise de l'activité après avoir essayé de les partager sur Facebook.

No DEBUG chaîne est connecté sur le Logcat. Donc, je comprends ShareDialog peut montrer la Photo de contenu.

Quelqu'un pourrait poster un simple exemple de partage d'image avec Facebook pour SDK 4.0(android)?
