How to set divider between spinner each item?

I looking for some solutions and try to complete it. The divider still doesn't show out.

I have set style for my theme in styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Others theme here. -->
    <item name="android:dropDownListViewStyle">@style/mySpinnerStyle</item>
</style>

Here is mySpinnerStyle

<style name="mySpinnerStyle" parent="android:Widget.ListView.DropDown">
    <item name="android:divider">#00ff00</item>
    <item name="android:dividerHeight">1dp</item>
</style>

Here is my fragment code for spinner:

Spinner chooseDate = (Spinner) view.findViewById(R.id.chooseDate);

String[] date_group = dateList.toArray(new String[dateList.size()]);
            ArrayAdapter<String> itemDate = new ArrayAdapter<String>(getActivity(), R.layout.spinner, date_group);
            itemDate.setDropDownViewResource(R.layout.spinner);
            chooseDate.setAdapter(itemDate);

Here is my spinner layout xml:

<Spinner
            android:theme="@style/mySpinnerStyle"
            android:spinnerMode="dialog"
            android:layout_gravity="center"
            android:layout_marginLeft="8dp"
            android:layout_marginRight="16dp"
            android:id="@+id/chooseDate"
            android:layout_width="match_parent"
            android:layout_height="38dp"
            android:background="@drawable/spinner_arrow" />

And then R.layout.spinner xml is like this:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:textSize="22dp"
    android:theme="@style/mySpinnerStyle"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:gravity="center"
    android:paddingRight="40dp"
    android:singleLine="true" />

I click my spinner shows dialog like this that is no divider in the end... enter image description here

I have set style for my spinner but i can't show divider. I don't know why ?

Any help would be appreciated . Thanks in advnace.

Manifests use my AppTheme:

<application
    android:allowBackup="true"
    android:icon="@drawable/app_icon_512x512"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:name="android.support.multidex.MultiDexApplication">
Solution

  • Remove the android:theme="@style/mySpinnerStyle" from your TextView (R.layout.spinner xml)

    And change this value from your spinner

    android:spinnerMode="dialog"

    Use this value

    android:spinnerMode="dropdown"
