AutoCompleteTextView、MultiAutoCompleteTextView自动完成输入内容的控件

如果我们想实现用户输入的内容有自动提示功能,类似百度搜索结果,AutoCompleteTextView和MultiAutoCompleteTextView可以实现类似功能

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);  
        //对list进行初始化  
        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中的数据对适配器adapter进行初始化  
        //第二个参数表示适配器为下拉风格  
        adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line,list);  
        //为AutoCompleteTextView添加适配器  
        autoTextView.setAdapter(adapter);  
  
        //multiAutoCompleteTextView添加适配器  
        multiAutoCompleteTextView.setAdapter(adapter);  
        //完成对选项的拆分,以逗号隔开  
        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>
