实现动态自动匹配的内容

AutoCompleteTextView 动态匹配输入的内容

AutoCompleteTextView 的特殊属性：

android:completionThreshold=“3” 这是设置输入多少字符时自动匹配

Demo

public class MainActivity extends Activity { private AutoCompleteTextView autoCompleteTextView; private String[] ar; private ArrayAdapter<String> arrayAdapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); autoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.completeTextView); ar = new String[]{"jiayuan", "jiazheng", "chenshi", "chenzheng"}; arrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,ar); autoCompleteTextView.setAdapter(arrayAdapter); } }

xml:

<AutoCompleteTextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/completeTextView"/>

MultiAutoCompleteTextView 可支持选择多个值（在多次输入的情况下），分别用分隔符分开，并且在每个值选中的时候再次输入值时会自动去匹配，可以用在发短信、发邮件时选择联系人这种类型中。

除了跟AutoCompleteTextView的特殊属性一样之外，MultiAutoCompleteTextView还有设置分隔符这个属性：

private MultiAutoCompleteTextView mt; mt.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());

Demo

public class MainActivity extends Activity { private MultiAutoCompleteTextView multiAutoCompleteTextView; private String[] ar; private ArrayAdapter<String> arrayAdapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); multiAutoCompleteTextView = (MultiAutoCompleteTextView) findViewById(R.id.completeTextView); ar = new String[]{"jiayuan", "jiazheng", "chenshi", "chenzheng"}; arrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,ar); multiAutoCompleteTextView.setAdapter(arrayAdapter); multiAutoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); } }

xml:

<MultiAutoCompleteTextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/completeTextView" android:hint="请输入"/>
