在微调删除pressed颜色 [英] Remove pressed color on Spinner

问题描述

我想删除蓝色（我测试我的霍洛应用程序）出现，当我点击一个微调。

I'd like to remove the blue color (I'm testing my app with Holo) appearing when I click on a Spinner.

我的code：

    ArrayAdapter<String> array_adapter = new ArrayAdapter<String> (getActivity(), 
            R.layout.spinner_item, string_array);
    array_adapter.setDropDownViewResource(R.layout.spinner_item);

    Spinner spinner = (Spinner) getView().findViewById(R.id.spinner);
    spinner.setAdapter(array_adapter);

spinner_item.xml

spinner_item.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/spinner_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAllCaps="true"
    android:background="@drawable/item"
    style="@style/EquidiaTheme.MySpinner" />

和item.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@android:color/transparent" />
    <item android:state_selected="true" android:drawable="@android:color/transparent" />
    <item android:drawable="@android:color/transparent" />
</selector>

这是行不通的。任何想法？

This doesn't work. Any idea?

推荐答案

我能摆脱，当我选择它的项目蓝色矩形时，我做到了这一点：
首先我声明，我想在values​​.xml用色彩：

I was able to get rid the blue rectangle on item when I select it when I done this: First I declare color that I want to use in values.xml:

<resources>
   <drawable name="red_color">#ff0000</drawable>
   <drawable name="blue_color">#0000ff</drawable>
   <drawable name="green_color">#00ff00</drawable>
   <drawable name="transparent_color">#00000000</drawable>
</resources>

比我定义Styles.xml自定义样式

Than I define custom style in Styles.xml

<resources>
    <style name="Theme.Spinner" parent="android:Theme.Holo">
        <item name="android:attr/listChoiceBackgroundIndicator">@drawable/transparent_color</item>
   </style>
</resources>

在我的风格就是只能使用在资源定义的颜色（设置颜色，如：@android：彩色/ XXX或#XXX直接在风格上没有工作）

in the style I was able to use only colors defined in resources ( Setting color like: @android:color/XXX or #XXX directly in style didn't work)

毕竟我aplly了他们的活动。我使用Xamarin，可能code是：

After all I aplly the them on Activity. I use Xamarin so may code is:

[Activity( Label = "TestLayouts", MainLauncher = true, Icon = "@drawable/icon", Theme="@style/Theme.Spinner")]

但Android的应该是：
   ＆LT;活动安卓主题=@风格/ Theme.Spinner＆GT;

我用这个答案以供参考：
<一href=\"http://stackoverflow.com/questions/9250215/default-selector-background-in-clickable-views\">Default在可点击浏览选择背景

I use this answer for reference: Default selector background in Clickable Views

也摆脱对微调蓝色矩形本身是：

also to get rid the blue rectangle on spinner itself use:

 <Spinner 
   android:background="@null"

您需要同时使用完全地消除蓝色rectable。
也可能这个属性的风格可以帮助你：

You need to use both to completly remove blue rectable. Also maybe this attributes in style may help you:

    <item name="android:attr/colorPressedHighlight">#FF0000</item>
    <item name="android:attr/colorLongPressedHighlight">#FF0000</item>
    <item name="android:attr/listChoiceIndicatorSingle">@drawable/red_color</item>
