In Android, autocompletetextview can automatically complete text input boxes, which is a bit like Ajax in Web pages. When using this function, you need to specify an adapter to set the completion.
<? XML version = "1.0" encoding = "UTF-8" ?>
< Linearlayout Xmlns: Android = "Http://schemas.android.com/apk/res/android"
Android: Orientation = "Vertical"
Android: layout_width = "Fill_parent"
Android: layout_height = "Fill_parent"
>
<! -- Define an Automatic completion text box, specify a character to input and then prompt -->
<! -- Android: dropdownhorizontaloffse -->
< Autocompletetextview
Android: ID = "@ + ID/auto"
Android: layout_width = "Fill_parent"
Android: layout_height = "Wrap_content"
Android: completionhint = "Select your favorite song"
Android: dropdownhorizontaloffset = "20dp"
Android: completionthreshold = "1" /> <! -- Specifies the number of words to be entered and a response prompt is displayed. -->
</ Linearlayout > Public Class Autocompletetextviewtest Extends Activity
{
// Define a string array as the prompt text
String [] books = New String [] {
"Sun Yanzi-Hey Jude ",
"Sun Yanzi-the moment ",
"Sun Yanzi-tonight I feel close to you ",
"Sun Yanzi-leave me alone"
};
@ Override
Public Void Oncreate (bundle savedinstancestate)
{
Super . Oncreate (savedinstancestate );
Setcontentview (R. layout. Main );
// Create an arrayadapter and encapsulate the Array
Arrayadapter <string> AA = New Arrayadapter <string> (
This ,
Android. R. layout. simple_dropdown_item_1line,
Books );
Autocompletetextview ACTV = (autocompletetextview)
Findviewbyid (R. Id. Auto );
// Set Adapter
ACTV. setadapter (AA );
}
}
