android spinner drop down items not shown

I'm trying to show simple spinner

    mSpinnerHeaderType = (Spinner) findViewById(R.id.spinner);
    String[] items = new String[]{Constants.TYPE_112R, Constants.TYPE_314R};
    ArrayAdapter<String> adapter = new ArrayAdapter<>(mContext, android.R.layout.simple_spinner_item, items);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    mSpinnerHeaderType.setAdapter(adapter);

In layout xml

<Spinner
         android:id="@+id/spinner"
         android:layout_width="100dp"
         android:layout_height="wrap_content"
         android:layout_gravity="center_vertical|left"
         android:spinnerMode="dropdown"></Spinner>

But when I click on spinner, either 1. the dropdown list width is almost zero OR 2. there are no itmes in dropdown

I tried, 1. giving spinner width as match_parent in xml layout and 2. using dropDownWith property for spinner etc, but nothing working

See image below:

What wrong I'm doing?

try this.

   mSpinnerHeaderType = (Spinner) findViewById(R.id.spinner);
       String[] items = {Constants.TYPE_112R, Constants.TYPE_314R};
        ArrayAdapter<String> adapter = new ArrayAdapter<>(mContext, android.R.layout.simple_spinner_item, items);
        mSpinnerHeaderType.setAdapter(adapter);

         android:layout_width="match_parent"
         android:layout_height="wrap_content"
