ListViewItem的没有得到强调，如果背景是不是透明 [英] ListViewItem does not get highlighted if the background isn't transparent

问题描述

我有一个自定义渐变背景的ListViewItem。默认选择不再突出了这些行了。

如果我将背景设置为透明高亮才有效。我怎样才能获得的亮点没有这种变化？

下面是我的ListView：

 ＆LT; ListView的机器人：ID =@ + ID / symbolsListView
    机器人：layout_width =FILL_PARENT
    机器人：背景=@绘制/ transparent_background
    机器人：layout_height =390dp
    机器人：分=@绘制/ ui_divider_line
    机器人：cacheColorHint =＃00000000
    机器人：listSelector =@绘制/蓝
    机器人：drawSelectorOnTop =真
    ＆GT;
 

解决方案

您一些国家是专注和window_focused。下面我提到的code的选择尝试。

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT;选择的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android＆GT;    ＆LT;项目的android：state_window_focused =false的机器人：可绘制=@色/透明/＆GT;    ＆LT;！ - 
        即使这两个指向相同的资源，具有两种状态，以便
        出来的pressed状态的时候，将绘制本身无效。
     - ＆GT;
    ＆LT;项目的android：state_focused =真正的机器人：state_enabled =假
        机器人：STATE_ pressed =真正的机器人：可绘制=@色/透明/＆GT;
    ＆LT;项目的android：state_focused =真正的机器人：state_enabled =假
        机器人：可绘制=@色/透明/＆GT;    ＆LT;项目的android：state_focused =真正的机器人：STATE_ pressed =真
        机器人：可绘制=@色/ solid_red/＆GT;
    ＆LT;项目的android：state_focused =false的机器人：STATE_ pressed =真
        机器人：可绘制=@色/ solid_red/＆GT;    ＆LT;项目的android：state_focused =真正的机器人：可绘制=@色/ solid_red/＆GT;＆LT; /选择＆GT;
 

希望工程。

I have a ListViewItem with a custom gradient background. The default selector no longer highlights these rows anymore.

Highlight only works if I set the background to transparent. How can I get the highlight without this change?

Here is my ListView:

<ListView android:id="@+id/symbolsListView"
    android:layout_width="fill_parent"
    android:background="@drawable/transparent_background"
    android:layout_height="390dp"
    android:divider="@drawable/ui_divider_line"
    android:cacheColorHint="#00000000"
    android:listSelector="@drawable/blue"
    android:drawSelectorOnTop="true"
    >

解决方案

your some states that are focused and window_focused. Below i mentioned the code for selector try this.

<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_window_focused="false" android:drawable="@color/transparent" />

    <!--
        Even though these two point to the same resource, have two states so
        the drawable will invalidate itself when coming out of pressed state.
    -->
    <item android:state_focused="true" android:state_enabled="false"
        android:state_pressed="true" android:drawable="@color/transparent" />
    <item android:state_focused="true" android:state_enabled="false"
        android:drawable="@color/transparent" />

    <item android:state_focused="true" android:state_pressed="true"
        android:drawable="@color/solid_red" />
    <item android:state_focused="false" android:state_pressed="true"
        android:drawable="@color/solid_red" />

    <item android:state_focused="true" android:drawable="@color/solid_red" />

</selector>

Hope it works.
