Android仿QQ输入法词根联想AutoCompleteTextView及多提示项群发邮件分隔录入MultiAutoCompleteTextView

怎么这么长，看着这么高大上呢。。

其实就是这个效果

显示的内容都是词根。。

private static final String[] data = new String[]{
"小猪猪", "小狗狗", "小鸡鸡", "小猫猫", "小咪咪"
};

不多说了，我们来贴代码吧

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">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="AutoCompleteTextView(自动完成文本框)"/>
<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" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MultiAutoCompleteTextView(多提示项的自动完成文本框)"/>
<MultiAutoCompleteTextView
android:id="@+id/matv_content"
android:layout_width="match_parent"
android:layout_height="48dp"
android:completionThreshold="1"
android:dropDownHorizontalOffset="5dp"
android:text="" />

</LinearLayout>
