Spinner drop down popup position changes in Nexus 5 (android 5.0)

问题

I am using a Spinner in my app. I used the basic spinner and this is my code:`

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    style="@style/SpinnerSpinnerTheme"
    android:spinnerMode="dropdown"
    android:layout_gravity="center_vertical"
    android:id="@+id/hj_order_date_spinner"
    />`

and this is how i instantiated in my activity

 ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,R.array.hj_spinner_items,android.R.layout.simple_spinner_item);
   adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    dateSpinner.setPrompt("Sort By");
    dateSpinner.setAdapter(adapter);

This works fine in android 4.4.4 but on Nexus 5(using Lollipop) the drop down list/Popup changes it's position and hides the "Sort By" bar or the original spinner. Can anyone provide any insight as to what might be the issue?

回答1:

You can specify whether the spinner drop-down should overlap the anchor by using the android:overlapAnchor attribute. When using the Material spinner style, this attribute defaults to true.

<Spinner
    ...
    android:overlapAnchor="false" />
