Extra space in AlertDialog

[illiaNaumov]

Trying to nest DocumentView in AlertDialog, but I've got extra space between text and right side:

Here is my code:
MainActivity.java

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button button = (Button) findViewById(R.id.button);

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showCommissionDialog();
        }
    });
}

private void showCommissionDialog() {
    MyAlertDialog dialog = new MyAlertDialog();
    dialog.show(getSupportFragmentManager(), "dialog");
}

}

MyAlertDialog.java

public class MyAlertDialog extends DialogFragment {

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getContext());

    View layout = getActivity().getLayoutInflater().inflate(R.layout.dialog, null);

    LinearLayout mContent = (LinearLayout) layout.findViewById(R.id.content);

    mContent.addView(addTosText());

    builder.setView(layout);

    return builder.create();
}


private DocumentView addTosText() {
    return makeDocumentView(new ArticleBuilder()
                    .append("d d d d d d d d d d d d d d d d d d d d d d d d d d d d d d d d d d " +
                            "d d d d d d d d d d d d d d d d d d d d d", false)
            , DocumentView.FORMATTED_TEXT);
}

public DocumentView makeDocumentView(CharSequence article, int type) {
    final DocumentView documentView = new DocumentView(getContext(), type);
    documentView.setText(article);
    documentView.getDocumentLayoutParams().setTextAlignment(TextAlignment.JUSTIFIED);

    return documentView;
}

}

dialog.xml

<LinearLayout
    android:id="@+id/content"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:orientation="vertical" />

How is it possible to avoid this extra space?

I could do this only by using below line of code:
documentView.getDocumentLayoutParams().setInsetPaddingRight(-60);

But this works differently for each form-factor

Could you please help with this issue?
