即（有微调等）打开一个弹出菜单视图里面显示三角形 [英] Show triangle inside the view that opens a popupmenu (like with a spinner)

问题描述

我有一个的ListView 它通过展示 POPUPMENU 处理的onclick事件。不过，我希望用户看到，可以单击景色内的小三角形。

I have a ListView which handles onClick events by showing a PopUpMenu. However, I want the user to see the little triangle inside the views that can be clicked.

我试图用一个微调，因为该元素看起来像我后，但我不能设置微调称号来比选择其他任何东西。

I tried using a Spinner, because that element looks like what I'm after, but I can't set the title of the Spinner to anything other than its options.

当然，我可以定做的一切，但因为这不是我想也许有一些已经在那里的新格局。我只是无法找到它自己。

Of course I could custom make everything but as this is not a new pattern I thought maybe there's already something out there. I just can't find it myself.

什么，我以后是示例：

推荐答案

如果您使用 ActionBarSherlock ，您可以用三角ABS用途：

If you use ActionBarSherlock, you can use the triangle ABS uses:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:tools="http://schemas.android.com/tools"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <TextView
        etc />

    <ImageView
        android:layout_width="32dp"
        android:layout_height="32dp"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:contentDescription="@string/expand_triangle"
        android:src="@drawable/abs__spinner_ab_default_holo_light" />

</RelativeLayout>
