similar case:textview of autocompletetextview showing data in single line

回答1:

Just need a LinerLayout to wrap the TextView in the layout of item:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/tv_search"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingTop="4dp"
    android:paddingBottom="4dp"
    android:singleLine="false"
    android:textColor="#000000"
    android:textSize="16dp"
    tools:text="test--------------------------------------test" />
 </LinearLayout>
