本文實例為大家分享了Android實現自動文本框提示的具體代碼,供大家參考,具體內容如下

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" > <!-- 默認輸2個字符才能有提示 completionThreshold表示只輸入1個字符后,就有提示 requestFocus表示界面展開時焦點直接在第二個文本框 --> <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>
代碼實現
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"}; /* * 創建適配器 * 參數一:上下文 * 參數二:提示下位框的樣式,不喜歡可以換android.R.layout.* * 參數三:下拉框中備選的內容 */ ArrayAdapter<String> adapter=new ArrayAdapter<String>( this, android.R.layout.simple_dropdown_item_1line, str); //將Adapter設置到AutoCompleteTextView中 myTextView01.setAdapter(adapter); myTextView02.setAdapter(adapter); //以","作為分隔符 myTextView02.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); }}以上就是本文的全部內容,希望對大家的學習有所幫助,也希望大家多多支持VEVB武林網。
