AutoCompleteTextView、MultiAutoCompleteTextView自動完成輸入內容的控制項

如果我們想實現使用者輸入的內容有自動提示功能，類似百度搜尋結果，AutoCompleteTextView和MultiAutoCompleteTextView可以實作類別似功能

MainActivity.JAVA:

public class MainActivity extends AppCompatActivity {        private AutoCompleteTextView autoTextView;      private MultiAutoCompleteTextView multiAutoCompleteTextView;      private ArrayList<String> list;      private ArrayAdapter<String> adapter;      @Override      protected void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.activity_main);            autoTextView = (AutoCompleteTextView) findViewById(R.id.autotext);          multiAutoCompleteTextView = (MultiAutoCompleteTextView) findViewById(R.id.multiauto);          //對list進行初始化          list = new ArrayList<String>();          list.add("123456");          list.add("12345");          list.add("1234");          list.add("google");          list.add("goole map");          list.add("goole chrome");            //使用list中的資料對適配器adapter進行初始化          //第二個參數表示適配器為下拉風格          adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line,list);          //為AutoCompleteTextView添加適配器          autoTextView.setAdapter(adapter);            //multiAutoCompleteTextView添加適配器          multiAutoCompleteTextView.setAdapter(adapter);          //完成對選項的拆分，以逗號隔開          multiAutoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());      }  }  

activity_main.xml：

<?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"      xmlns:tools="http://schemas.android.com/tools"      android:layout_width="match_parent"      android:layout_height="match_parent"      android:orientation="vertical"      tools:context="com.example.administrator.edittextdemo.MainActivity">        <TextView      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:id="@+id/textview1"      android:text="AutoCompleteTextView"/>        <AutoCompleteTextView          android:id="@+id/autotext"          android:layout_width="match_parent"          android:layout_height="wrap_content" />        <TextView          android:layout_width="match_parent"          android:layout_height="wrap_content"          android:id="@+id/textview2"          android:text="MultiAutoCompleteTextView"/>        <MultiAutoCompleteTextView          android:id="@+id/multiauto"          android:layout_width="match_parent"          android:layout_height="wrap_content" />  </LinearLayout>
