Android enables dynamic matching of input content Autocompletetextview and Multiautocompletetextview

Autocompletetextview
1. Function:
Dynamically match the input content, such as Baidu search engine when the input text can be displayed according to the content of popular information matching.
2. Unique attributes:
Android:completionthreshold set How many characters are entered automatically when you match

Using Autocompletetextview to implement automatic matching of input content
Private Autocompletetextview Actextview;
Initializing the control
Actextview = (Autocompletetextview) Findviewbyid (R.ID.AUTOCOMPLETETEXTVIEW1);
Initialize the data source (the res array in the code adds some more)
Private string[] res = new string[] {"Moon", "Month", "Moonlight", "Moonlight Poet"};
Create an adapter (use Arrayadapter here)
arrayadapter<string> adapter = new Arrayadapter<string> (this, Android. R.layout.simple_expandable_list_item_1, RES);
The adapter is bound to the current Autocompletetextview (via the. Setadapter () method)
Actextview.setadapter (adapter);
The contents of adapter appear in Activity_main.xml settings when you enter how many characters
android:completionthreshold= "1"

Multiautocompletetextview
1. function
Can support the selection of multiple values (in the case of multiple input), separated by a delimiter, and the value of each value is checked again automatically to match, can be used in text messaging, e-mail to select the type of contact.
2. Unique attributes:
Android:completionthreshold set How many characters are entered automatically when you match
3. Set the delimiter
Mtxt.settokenizer (New Multiautocompletetextview.commatokenizer ());

Using Multiautocompletetextview to implement automatic matching of input content
The exact steps are similar to Autocompletetextview.
Set the delimiter (set with a comma delimiter)
Mactextview.settokenizer (New Multiautocompletetextview.commatokenizer ());
