Android Learning Start-Autocompletetextview and Multiautocompletetextview controls using

When you search with Baidu, enter a few words on the drop-down box can be selected, the following two controls have this function

Autocompletetextview: Only the start of the input, only one match

Multiautocompletetextview: You can match multiple inputs, separating each input with a delimiter, just like when you send an email with multiple contacts, see example:

First, the effect of Autocompletetextview is as follows

The layout file is as follows

1 <?XML version= "1.0" encoding= "Utf-8"?>2 <LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"3 Android:layout_width= "Match_parent"4 Android:layout_height= "Match_parent"5 android:orientation= "vertical" >6 7     8     <!--Property EMS indicates that a drop-down match box is displayed starting with the first word -9     <AutocompletetextviewTen         Android:id= "@+id/autocompletetextview1" One Android:layout_width= "Match_parent" A Android:layout_height= "Wrap_content" - Android:ems= "2"   - Android:hint= "Please enter keyword search" > the  -         <Requestfocus/> -     </Autocompletetextview> -  + </LinearLayout>

The code files are as follows

1  PackageCom.example.demo4;2 3 Importandroid.app.Activity;4 ImportAndroid.os.Bundle;5 ImportAndroid.widget.ArrayAdapter;6 ImportAndroid.widget.AutoCompleteTextView;7 8  Public classMyactivitymainactivityextendsActivity {9     Ten     PrivateAutocompletetextview Actextview; One  A @Override -     protected voidonCreate (Bundle savedinstancestate) { -         Super. OnCreate (savedinstancestate); the Setcontentview (r.layout.activity_main); -          -         //get to the control instance -Actextview =(Autocompletetextview) Findviewbyid (r.id.autocompletetextview1); +          -         //defines a string array to match the input keyword +string[] DSR =Newstring[] { A"Zhangshang", "Zhangshi", "Zhangzhang",  at"Lishang", "Ligang",  -"Chengcheng", "Chengzhi", -"Wangwu" -                 }; -          -         //Initializes a drop-down data source adapter to match the input inArrayadapter<string> adptr =NewArrayadapter<string>( -                  This,//Current Object toAndroid. R.layout.simple_list_item_1,//This is a system with its own layout +Dsr//Data Source -                 ); the                  *         //to set the Autocompletetextview control's matching device $ Actextview.setadapter (adptr);Panax Notoginseng          -     } the      +      A}

Second, the Multiautocompletetextview achieve the following results

Layout file is not on, it is a change of a control, directly look at the code, there is more than one statement

1  PackageCom.example.demo4;2 3 Importandroid.app.Activity;4 ImportAndroid.os.Bundle;5 ImportAndroid.widget.ArrayAdapter;6 ImportAndroid.widget.MultiAutoCompleteTextView;7 8  Public classMyactivitymainactivityextendsActivity {9     Ten     PrivateMultiautocompletetextview Mactextview; One  A @Override -     protected voidonCreate (Bundle savedinstancestate) { -         Super. OnCreate (savedinstancestate); the Setcontentview (r.layout.activity_main); -          -         //get to the control instance -Mactextview =(Multiautocompletetextview) Findviewbyid (r.id.multiautocompletetextview1); +          -         //defines a string array to match the input keyword +string[] DSR =Newstring[] { A"Zhangshang", "Zhangshi", "Zhangzhang",  at"Lishang", "Ligang",  -"Chengcheng", "Chengzhi", -"Wangwu" -                 }; -          -         //Initializes a drop-down data source adapter to match the input inArrayadapter<string> adptr =NewArrayadapter<string>( -                  This,//Current Object toAndroid. R.layout.simple_list_item_1,//This is a system with its own layout +Dsr//Data Source -                 ); the                  *         //to set the Autocompletetextview control's matching device $ Mactextview.setadapter (adptr);Panax Notoginseng          -         //device Multiple Input separator, here is a comma theMactextview.settokenizer (NewMultiautocompletetextview.commatokenizer ()); +          A     } the      +      -}

Finished, is not so easy,multiautocompletetextview than Autocompletetextview add a separate statement just, special is son inherited a more function!!!
