title: Lottie with DialogFragment background problem
body: <p>im using a Lottie Library to give some animation to my app. Im testing a simple loading example with a DialogFragment, but the background color of dialog is white and im need that color to be invisible.</p>
  
  <p>Activity:</p>
  
  <pre><code>public class MainActivity extends AppCompatActivity implements MainActivityContract.View{
  
  private ProgressDialog progressDialog;
  private Button button;
  private MainActivityContract.Presenter presenter;
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
  
      button = findViewById(R.id.button);
  
      button.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View view) {
  
  
          }
      });
  
      presenter = new MainActivityController(this);
      presenter.initInterface();
  }
  
  @Override
  public void initProgressBar() {
      progressDialog = new ProgressDialog();
      progressDialog.show(getSupportFragmentManager(),"teste");
  }
  
  @Override
  public void finishProgressBar() {
      progressDialog.dismiss();
  }
  }
  </code></pre>
  
  <p>Layout:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:background="@color/invisible"
  xmlns:app="http://schemas.android.com/apk/res-auto"&gt;
  
  &lt;com.airbnb.lottie.LottieAnimationView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      app:lottie_autoPlay="true"
      app:lottie_rawRes="@raw/glow_loading"
      app:lottie_loop="true"/&gt;
  
  &lt;/FrameLayout&gt;
  </code></pre>
  
  <p>and that is my background color:</p>
  
  <pre><code>&lt;color name="invisible"&gt;#00ffffff&lt;/color&gt;
  </code></pre>
