Question

我有一份清单,附有按习俗梯度的背景。缺省遴选人不再强调这些行文。

我只有把背景确定为透明,才能突出工作。如果没有这一变化,我怎么能看到这个亮点?

一、导言

<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"
    >

Answer 1

你们的一些国家以重点和窗口为重点。下面,我提到了《挑选者守则》。

<?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>

希望会发挥作用。

Answer 2

各位使用“名单者”属性提供的额外证据突出表明了目前对清单意见的选择。

缺席,可提取选任人列在清单项目后面。因此,如果贵重物品的梯度背景不透明,就永远不会显示选择者。

有两个解决办法:

Make the background gradient transparent by lowering alpha values.
Set the "drawSelectorOnTop" attribute to true, so that the selector is drawn on top of the list item. In this case, make sure your selector drawable is not fully opaque.

Answer 3

使用<代码><selector>显示具有梯度背景的“压缩”状态。
