Unable to scroll through dialog fragment

I'm trying to get a popup DialogFragmentand show a scrollable legend TextView, but it just cuts off the rest of the legend. I cannot scroll it or anything else. I tried adding ScrollView, but does nothing. This is the screen I get:

enter image description here

This is my XML layout file:

<?xml version="1.0" encoding="utf-8"?>

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">

    <LinearLayout android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:scrollbars="vertical"
        android:scrollbarAlwaysDrawVerticalTrack="true"
        android:background="#fff">

        <TextView
            android:id="@+id/layer_legend_title_textview"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:paddingLeft="10dp"
            android:paddingRight="10dp"
            android:background="#fff"
            android:textColor="#000" />

        <ListView
            android:id="@+id/layer_legend_symbols_listview"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="20dp"
            android:background="#fff"
            android:textColor="#000" />

    </LinearLayout>

</ScrollView>

I run this to add content to TextView:

/**
 * A dialog that shows the legend of a ArcGISDynamicMapServiceLayer.
 */
public class LegendDialogFragment extends DialogFragment implements View.OnClickListener {

    public static final String TAG = LegendDialogFragment.class.getSimpleName();
    private LinearLayout mLinearLayout;
    private ArcGISDynamicMapServiceLayer mLayer;
    private ImageButton backButton;

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        mLinearLayout = (LinearLayout) inflater.inflate(R.layout.legend_dialog_fragment_layout, null);
        getDialog().setTitle(getActivity().getString(R.string.legend));

        mLayer = ((MainActivity) getActivity()).getLayer();

        backButton = (ImageButton) mLinearLayout.findViewById(R.id.backButton2);
        backButton.setOnClickListener(this);
        // before we can show the legend we have to fetch the legend info asynchronously
        new FetchLegendTask().execute();

        return mLinearLayout;
    }

    public void onAttach(Activity activity) {
        super.onAttach(activity);

        if (!(activity instanceof MainActivity)) {
            throw new IllegalStateException("Hosting activity needs to be of type MainActivity");
        }
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.backButton2:
                getDialog().dismiss();
                break;
        }
    }

    /**
     * Retrieves the legend information asynchronously from the ArcGISDynamicMapServiceLayer.
     */
    private class FetchLegendTask extends AsyncTask<Void, Void, Void> {

        @Override
        protected Void doInBackground(Void... params) {
            mLayer.retrieveLegendInfo();
            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            super.onPostExecute(result);

            for (ArcGISLayerInfo layerInfo : mLayer.getAllLayers()) {
                if(layerInfo.isVisible()){
                    View view = getActivity().getLayoutInflater().inflate(R.layout.layer_legend_layout, null);
                    populateLegendView(view, layerInfo);

                    mLinearLayout.addView(view);
                }
            }
        }

        private View populateLegendView(View view, ArcGISLayerInfo layerInfo) {
            if (layerInfo != null) {
                TextView textView = (TextView) view.findViewById(R.id.layer_legend_title_textview);

                textView.setText(layerInfo.getName());
            }
            return view;
        }
    }

}

I want everything to Fragmentbe scrollable, but I don’t know how to achieve this. Whenever I try to turn ScrollViewit on , it scrolls the rest of this particular line. It will not show all content. I think this is more related to DialogFragment.
