AutoCompleteTextview、MultiAutoCompleteTextView

AutoCompleteTextview

    动态匹配输入内容文本框

     属性：

          android:completionThreshold="2";     设置输入多少字符时自动匹配

 

public class MainActivity extends ActionBarActivity {

        private AutoCompleteTextView actextview ;

        //初始化数据源  去匹配文本框中输入的内容

        private String[] res ={"北京" ,"北京1" ,"北京2" ,"上海" ,"上海1" ,"上海2" };

       

        @Override

        protected void onCreate(Bundle savedInstanceState) {

               super.onCreate(savedInstanceState);

              setContentView(R.layout. activity_main);

               //初始化控件

               actextview=(AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1 );

               //New适配器

              ArrayAdapter<String> adapter= new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1 ,res );

               //将adpter 与当前AutoCompleteTextView控件绑定

               actextview.setAdapter(adapter);

       }

}

 

 

<AutoCompleteTextView

        android:id="@+id/autoCompleteTextView1"

        android:layout_width="match_parent"

        android:layout_height="50dp"

        android:completionThreshold="1"

        android:hint="@string/AutoCompleteTextView" >

        <requestFocus />

    </AutoCompleteTextView >

 

 

 

 

 

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，并且在每个字选中的时候再次输入值时会自动去匹配。（AutoCompleteTextview 单选）

       android:completionThreshold="2";     设置输入多少字符时自动匹配

        mtxt.setTokenizer(new MultiAutoCompleteTextView.CommTokenizer());

maTextView=(MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteTextView1 );

maTextView.setAdapter(adapter);

//设置分隔符

maTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
