Android Automatic text box input recognition hint function code _android

Automatic prompt text box (Autocompletetextview) can enhance the user experience, shorten the user's input time (Baidu's search box is this effect).

I believe we are familiar with the automatic identification tips, in our life everywhere, today let me give you a brief introduction of how it is designed.

The so-called automatic recognition input is based on the user input of the existing information, for users to prompt the possible value, user-friendly completion of input. On Android devices This feature is divided into: Autocompletetextview and Multiautocompletetextview, the former as a single automatic recognition, similar to the Search engine input box prompts; the latter is automatically recognized for multiple values, Similar to the Mailbox entry box when you send a message. So how exactly do they use them? Now let's study together.

The first is the layout file:

 <relativelayout xmlns:android= "Http://schemas.android.com/apk/res/android" xmlns:tools= "Http://schemas.android.com/tools" android:layout_width= "match_parent" android:layout_height= "Match_" Parent "android:paddingbottom=" @dimen/activity_vertical_margin "android:paddingleft=" @dimen/activity_horizontal_ Margin "android:paddingright=" @dimen/activity_horizontal_margin "android:paddingtop=" @dimen/activity_vertical_ Margin "tools:context=".
Activityfive "> <autocompletetextview android:id=" @+id/actextview "android:layout_width=" Match_parent "
android:layout_height= "wrap_content" android:hint= "Please enter your name:" android:textcolor= "#000" android:maxlength= "ten"/> <multiautocompletetextview android:id= "@+id/mactextview" android:layout_below= "@id/actextview" Android:layout_ Width= "Match_parent" android:layout_height= "wrap_content" android:hint= "Please enter the city:" Android:textcolor= "#000" Android: Maxlength= "/>" </RELATIVELAYOUT> 

Note: The Android:hint property is the hint text content, automatically disappears when the input box gets focus

Here's our action:

Import android.app.Activity;
Import Android.os.Bundle;
Import Android.widget.ArrayAdapter;
Import Android.widget.AutoCompleteTextView;
Import Android.widget.MultiAutoCompleteTextView; public class Activityfive extends activity{private Autocompletetextview Actextview private Multiautocompletetextview
Mactextview;
Private String [] arr = {"abc", "ABX", "Abo", "BDC", "BDF"};
Private String [] brr = {"AB Beijing", "AB Nanjing", "Ab Tokyo", "BB Moscow", "BB uk", "BB USA"}; @Override protected void OnCreate (Bundle savedinstancestate) {//TODO auto-generated Method stub super.oncreate (savedins
Tancestate);
Setcontentview (r.layout.activity_five);
Actextview = (Autocompletetextview) Findviewbyid (R.id.actextview);
Mactextview = (Multiautocompletetextview) Findviewbyid (R.id.mactextview); arrayadapter<string> arradapt = new Arrayadapter<string> (this, Android. 
R.layout.simple_dropdown_item_1line, arr);
Actextview.setadapter (ARRADAPT); arrayadapter<string> brradapt = new Arrayadapter<string> (This, androiD.r.layout.simple_dropdown_item_1line, BRR);
Mactextview.setadapter (BRRADAPT); Mactextview.setthreshold (1);/set how many characters to enter to start automatically matching Mactextview.settokenizer (new Multiautocompletetextview.commatokenizer ());//Set Separator}}
