textColor of my AutoCompleteTextView is always white

问题

For some reason, no matter what I do the text coming up in my AutoCompleteTextView is always white. I've explicitly set textColor to black in my XML. I'm wondering if android.R.layout.simple_list_item_1 is white by default?

Here is where I set up my ArrayAdapter:

final ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1, strings);
                    AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.searchUserTextField);
                    textView.setAdapter(adapter);

Here is my XML:

<AutoCompleteTextView
            android:layout_width="match_parent"
            android:layout_height="65dp"
            android:background="@drawable/edittext_border"
            android:layout_gravity="top"
            android:textColor="#000000"
            android:hint="@string/search_user"
            android:id="@+id/searchUserTextField"
            android:ems="150"
            android:paddingLeft="25dp"
            android:paddingTop="10dp"
            android:paddingRight="10dp"
            android:paddingBottom="10dp"
            android:maxLines ="4"
            android:maxLength ="150"
            android:scrollHorizontally="false"
            android:typeface="sans"
            android:textSize="14sp"
            android:fontFamily="sans-serif-light"
            android:capitalize="none"
            android:inputType="textEmailAddress"
            android:gravity="center_vertical"
            android:layout_alignParentTop="true"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_toLeftOf="@+id/submitSearch"
            android:layout_toStartOf="@+id/submitSearch" />

Looked like its a logged bug in AOSP. You can find some more information as well as workarounds in this post AutoCompleteTextview Color set white by default

Just to add, in case someone is still looking for an answer that works as it is not a bug but you can provide your custom layout for autocomplete suggestions as follows:

Change this line of code

final ArrayAdapter<String> adapter = new ArrayAdapter<String (getApplicationContext(), android.R.layout.simple_list_item_1, strings);

final ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.custom_autocomplete, strings);

Make a layout resource file as custom_autocomplete.xml and provide required settings. Working template

<?xml version="1.0" encoding="utf-8"?>
    <TextView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textColor="@color/colorPrimary"
        android:background="@color/white"
        android:paddingHorizontal="10dp"
        android:paddingVertical="15dp" />

Change the default layout for drop down item view to your own custom layout containing only TextView:

Example ( In Kotlin )-

Replace android.R.layout.select_dialog_item in the line:

val adapter: ArrayAdapter<String> = ArrayAdapter<String>(this, android.R.layout.select_dialog_item,gender)

To:

val adapter: ArrayAdapter<String> = ArrayAdapter<String>(this, R.layout.item_drop_down,gender)

where gender is :

private var gender :Array<String> = arrayOf("Male", "Female", "Others")

Here is the custom layout file : item_drop_down

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="@color/appBlue"
android:gravity="center_vertical"
android:paddingStart="14dip"
android:paddingEnd="15dip"
android:ellipsize="marquee"
android:textSize="@dimen/sp_15"
/>

Hope this might help somebody! Happy Coding :)
