本节引言:
1.相关属性:
另外其实还有个MultiAutoCompleteTextView(多提示项的自动完成文本框) 和这个AutoCompleteTextView作用差不多,属性也一样,具体区别在哪里, 我们在下面的代码中来体验~另外这两个都是全词匹配的,比如,小猪猪: 你输入小->会提示小猪猪,但是输入猪猪->却不会提示小猪猪!
2.代码示例:
运行效果图:
实现代码:
这里的话就不自定义布局了,直接用ArrayAdapter来实现吧!
布局文件:activity_main.xml:
<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=".MainActivity"> <AutoCompleteTextView android:id="@+id/atv_content" android:layout_width="match_parent" android:layout_height="48dp" android:completionHint="请输入搜索内容" android:completionThreshold="1" android:dropDownHorizontalOffset="5dp" /> <MultiAutoCompleteTextView android:id="@+id/matv_content" android:layout_width="match_parent" android:layout_height="48dp" android:completionThreshold="1" android:dropDownHorizontalOffset="5dp" android:text="" /> </LinearLayout>
MainActivity.java:
public class MainActivity extends AppCompatActivity { private AutoCompleteTextView atv_content; private MultiAutoCompleteTextView matv_content; private static final String[] data = new String[]{ "小猪猪", "小狗狗", "小鸡鸡", "小猫猫", "小咪咪" }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); atv_content = (AutoCompleteTextView) findViewById(R.id.atv_content); matv_content = (MultiAutoCompleteTextView) findViewById(R.id.matv_content); ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity. this, android.R.layout.simple_dropdown_item_1line, data); atv_content.setAdapter(adapter); ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_dropdown_item_1line, data); matv_content.setAdapter(adapter); matv_content.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); } }
