Android Autocompletetextview Control Basic Usage Example _android

This example describes the basic usage of the Android Autocompletetextview control. Share to everyone for your reference, specific as follows:

When the input part of the content will have related suggestions, similar to the Baidu hint information

1. Declare a autocompletetextview in the layout file

<autocompletetextview
    android:id= "@+id/autocomplete_country"
    android:layout_width= "Fill_parent"
    android:layout_height= "wrap_content"
    android:layout_marginleft= "5DP"
  />

2, the definition of a hint entry style, in the layout directory to establish list_item.xml files

<?xml version= "1.0" encoding= "Utf-8"?> <textview xmlns:android=
  "http://schemas.android.com/apk/" Res/android "
  android:layout_width=" fill_parent "
  android:layout_height=" Fill_parent "
  android: padding= "10DP"
  android:textsize= "16sp"
  android:textcolor= "#000" >
</TextView>

3, it needs to use Arrayadapter to provide data

public void Setautocompletetextview () {
  Autocompletetextview = (autocompletetextview) Findviewbyid ( R.id.autocomplete_country);
  Countries is an array that Autocompletetextview matches the contents of the array with the input of the user and then displays to prompt the user
  //r.layout.list_item to display the style
  of the content displayed by the hint message arrayadapter<string> arrayadapter = new Arrayadapter<string> (this, R.layout.list_item, COUNTRIES);
  Autocompletetextview.setadapter (Arrayadapter);
}

Note: Countries is an array type
