AutoCompleteTextView Example
In this Example we create a AutoCompleteTextView .We use an ArrayAdapter for displaying content.
activity_main
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:orientation="vertical" android:layout_height="match_parent" tools:context=".MainActivity"> <AutoCompleteTextView android:layout_width="match_parent" android:layout_marginTop="100dp" android:layout_height="wrap_content" android:hint="Enter your country" android:id="@+id/autoComplete_tv"/> </LinearLayout> |
In MainActivity we declare array type variable ‘country’ and store some values.
And use ArrayAdapter class and set this adapter to AutoCompleteTextView .
