Android Hide Text if not data is found

I'm extracting data from a database and displaying it on my app. Not every item I'm displaying on my app has the same information so in my text view I'm getting blank items that are appearing. That's something I def. don't want. My question is, is their a android method that will not display blank information? Can I somehow hide the xml?

You can and here's the Android Documentation for it, Shane.

Hope this helps! -David

David, I can see what your saying and thanks for your help but this doesn't completely answer my question. If I'm pulling null or blank data from my database then i don't want that white space to be visible in my view. How would I account for that white space? Thanks

Below is my syntax account for not a null value but I'm still getting white space in my view?

infoHolder.yelp = (TextView) convertView.findViewById(R.id.theYelp);

            if(infoHolder.yelp !=null){
                infoHolder.yelp.setVisibility(View.VISIBLE);
            } else {
                infoHolder.yelp.setVisibility(View.INVISIBLE);
            }

Okay. then you need to use (View.GONE) instead of View.INVISIBLE for your else condition, Shane. If that doesn't work then using an Adapter for your the data in your TextView and the method isEmpty() for the else condition should hopefully do the trick. Here's the documentation for it https://developer.android.com/reference/android/widget/Adapter.html

Hope this helps and thanks for clarifying what your problem is.

Hi David

Thanks for the help. I appreciate it but I'm still at loggerheads.

Below is an example of my XML (I've opted not to display the entire file)

        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:visibility="gone"
            android:text="Facebook"
            android:autoLink="web"
            android:id="@+id/theFacebook"
            android:layout_column="0"
            android:layout_weight="1" />

    </TableRow>

Here is my logic. Here I'm using isEnabled() method

   infoHolder.facebook = (TextView) convertView.findViewById(R.id.theFacebook);
              if(infoHolder.facebook != null){
                infoHolder.facebook.setVisibility(View.VISIBLE);
            } else if (infoHolder.facebook.isEnabled()) {
                infoHolder.facebook.setVisibility(View.GONE);
                Toast.makeText(activity, "Facebook Gone",    Toast.LENGTH_LONG).show();
            }

I tested it out again and here is my other logic. Here I typed cast Adapter and used isEmpty()

    infoHolder.facebook = (TextView) convertView.findViewById(R.id.theFacebook);
            if(infoHolder.facebook != null){
                infoHolder.facebook.setVisibility(View.VISIBLE);
            } else if (((Adapter) infoHolder.facebook).isEmpty()) {
                infoHolder.facebook.setVisibility(View.GONE);
                Toast.makeText(activity, "Facebook Gone",     Toast.LENGTH_LONG).show();
            }

It's still not working. What am I doing wrong?

Thanks again
