定制Android的ListView的颜色？ [英] Customizing Android ListView Colors?

问题描述

我已经冲刷的interwebs发现关于如何改变使用列表选择列表视图的颜色很多帖子。然而，它似乎并没有为我工作。所以我的问题是我在做什么错了？

I've scoured the interwebs and found many posts regarding how to change the colors of a list view using a list selector. However it does not seem to work for me. So my question would be what am I doing wrong?

当我使用下面的文件，我得到一个列表，其中所有的项目背景是最初的蓝色。 （我预计白）

When I use the below files I get a list where all item backgrounds are initially blue. (I expected white)

当我移动焦点上下文刚变为暗灰色，而该项目的背景仍然是蓝色的。 （这是我所期望的单排是蓝色的，其余白色）

When I move the focus up and down the text just changes to a dark grey and the item backgrounds are still blue. (This is when I would expect a single row to be blue with the rest white)

当我点击一个行我点击了行的背景变成黑屏，所有其他行翻绿。 （我预计将有我点击变绿行，其余是白色）

When I click on a row the background of the row I clicked on turns black and all other rows turned green. (I expected to have the row I clicked turn green and the rest be white)

下面是我的主要布局文件：

Here is my main layout file:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<ListView
    android:id="@android:id/list"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:listSelector="@drawable/item_selector"
    />
<TextView
    android:id="@android:id/empty"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/empty"
    />
</LinearLayout>

下面是我的列表项的文件：

Here is my list item file:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:orientation="horizontal" 
    android:padding="10sp">
    <CheckBox
        android:id="@+id/checkbox"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:focusable="false"
        />
    <TextView 
        android:id="@+id/title" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:ellipsize="end"
        android:singleLine="true" 
        android:textStyle="bold"
        android:padding="7dip"
        android:textSize="18sp"
        android:layout_toRightOf="@id/checkbox"
        />
</RelativeLayout>

下面是我的颜色文件：

<?xml version="1.0" encoding="utf-8"?>
<resources> 
    <color name="red">#ff00</color>
    <color name="green">#f0f0</color>
    <color name="blue">#f00f</color>
    <color name="white">#ffff</color>
</resources>

下面是我的选择文件：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:state_pressed="true" 
        android:drawable="@color/green" />
    <item 
        android:state_focused="true" 
        android:drawable="@color/blue" />
    <item 
        android:drawable="@color/white" />
</selector>

希望这是愚蠢的事情，简单的说，我做错了。

Hopefully it's something dumb and simple that I'm doing wrong.

在此先感谢。

推荐答案

我觉得机器人：listSelector =@可绘制/ item_selector只适用于视图的根并不在他的所有subchild

I think that android:listSelector="@drawable/item_selector" is applied only on the root of the view not at all his subchild.

尝试添加@绘制/ item_selector为您RelativeLayout的的研究背景与安卓背景=@可绘制/ item_selector，把一个透明布局的listSelector：

Try to add @drawable/item_selector as a backgroud of your RelativeLayout with android:background="@drawable/item_selector" and put a transparent layout to the listSelector:

android:listSelector="@android:color/transparent"
