本文实例为大家分享了Android实现自动文本框提示的具体代码，供大家参考，具体内容如下
activity_main.xml布局
<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" > <!-- 默认输2个字符才能有提示 completionThreshold表示只输入1个字符后，就有提示 requestFocus表示界面展开时焦点直接在第二个文本框 --> <AutoCompleteTextView android:id="@+id/myTextView01" android:layout_width="match_parent" android:layout_height="wrap_content" android:completionThreshold="1" /> <MultiAutoCompleteTextView android:id="@+id/myTextView02" android:layout_width="match_parent" android:layout_height="wrap_content" android:completionThreshold="1"> <requestFocus /> </MultiAutoCompleteTextView> </LinearLayout>
代码实现
public class MainActivity extends Activity { private AutoCompleteTextView myTextView01; private MultiAutoCompleteTextView myTextView02; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); myTextView01 = (AutoCompleteTextView) findViewById(R.id.myTextView01); myTextView02 = (MultiAutoCompleteTextView) findViewById(R.id.myTextView02); String[] str={"xiaohe","xiaowang","xiaoli","zhanghe","zhangmin","zhaojun","lihe","daming"}; /* * 创建适配器 * 参数一：上下文 * 参数二：提示下位框的样式，不喜欢可以换android.R.layout.* * 参数三：下拉框中备选的内容 */ ArrayAdapter<String> adapter=new ArrayAdapter<String>( this, android.R.layout.simple_dropdown_item_1line, str); //将Adapter设置到AutoCompleteTextView中 myTextView01.setAdapter(adapter); myTextView02.setAdapter(adapter); //以","作为分隔符 myTextView02.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); } }
