Android MultiAutoCompleteTextView可将多个联系人检索到MultiAutoCompleteTextView

我很抱歉，如果这看起来像同一个问题很多次…但谷歌搜索这个没有提供任何结果 这可能与相同，但无法获得解决方案

我试图修改我在stackoverflow上看到的AutoCompleteTextView的代码，以便为MultiAutoCompleteTextView返回多个联系人。 当iam在elulator上执行时，我再也看不到任何可供选择的建议。我觉得这是个问题

提前感谢您的帮助

我的multiautocompletetextview有以下代码：

<MultiAutoCompleteTextView
     android:id="@+id/mmWhoNo"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:textColor="#0000A0"
     android:hint="Choose your Contacts" />

任何人都可以建议我获取多个联系方式。关于MultiAutoCompleteTextView

    }


}

we have to change in manifast.xml


<uses-permission android:name="android.permission.WRITE_CONTACTS"/>
    <uses-permission android:name="android.permission.READ_CONTACTS" />
