Android Textview 背景颜色资源

【问题描述】：

我有一个listView。 custom_listitem1.xml 用于列表中显示的项目。现在我想为项目的背景设置基于Selector 的颜色资源（list_selector_color.xml）。

custom_listitem1.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textColor="#000000"
    android:textSize="18sp"
    android:textStyle="bold"
    android:background="@color/list_selector_color"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:gravity="center_vertical"
    android:paddingLeft="6dip"
    android:minHeight="?android:attr/listPreferredItemHeight"/>

list_selector_color.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
          android:color="#ffff0000"/> <!-- pressed -->
    <item android:state_focused="true"
          android:color="#ff0000ff"/> <!-- focused -->
    <item android:color="#ff000000"/> <!-- default -->
</selector>

但它给出了以下错误.....

我的代码有什么问题？

【问题讨论】：

  • 您在项目中放置 list_selector_color.xml 文件的位置。
  • 我建议将“list_selector_color.xml”放在 res/drawable 文件夹中。如果不存在，请先在 res 目录下创建“drawable”文件夹。

标签： android background textview selector


【解决方案1】：

您不能使用颜色选择器作为背景。您可以改用可绘制选择器：

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

    <item android:state_pressed="true">
        <shape>
            <solid android:color="#ffff0000"/>
        </shape>
    </item><!-- pressed -->

    <item android:state_focused="true">
        <shape>
            <solid android:color="#ff0000ff"/>
        </shape>
    </item><!-- focused -->

    <item>
        <shape>
            <solid android:color="#ff000000"/>
        </shape>
    </item><!-- default -->

</selector>

您必须将其放入drawable/ 文件夹而不是color/ 并以身份访问

android:background="@drawable/list_selector_color"

【讨论】：

  • 老兄！我从没想过在 标签中创建形状！你是个天才。我一直讨厌我不能直接在 标签中使用 android:color，因此我总是会为每个 ! 创建单独的文件

【讨论】：

  • 我需要在同一视图的不同状态（例如按下、聚焦）下使用不同的颜色。让默认颜色为黑色，按下时为黄色，若对焦为红色。你的代码怎么可能？
【解决方案3】：

您将 list_selector_color.xml 存储在哪里？ 如果它在 res/color 中，请尝试将其重新定位到 res/drawable 并像android:background="@drawable/list_selector_color"一样打电话

【讨论】：

  • 这不起作用 - list_selector_color.xml 文件会导致运行时错误，因为如果从可绘制文件夹中提取每个 都需要设置 android:drawable 属性。拥有 android:color 集是不够的。 :\
【解决方案4】：

您需要在 ...\res\values\color.xml 项目目录中创建color.xml。
样本color.xml文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="background">#1474c0</color>
<color name="row">#ff0000</color>
<color name="translucent_red">#ff0000</color>
</resources>

那么如何使用颜色呢？请看这个例子并添加一行+++++++ 示例 main.xml 文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"
    android:layout_height="wrap_content"
+++++++android:background="@color/translucent_red">
<ListView android:id="@+id/android:list"
      android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
<TextView android:id="@+id/android:empty"
      android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="No Notes!"/>
</LinearLayout>

【讨论】：

  • 我想在 TextView 的不同状态（例如按下、聚焦）下显示不同的颜色。怎么可能以你的方式？
【解决方案5】：

是的，如果您将每个 textview 定义到每个 LinearLayout 中，那么它可以工作。

【讨论】：

  • 您能否提供一些代码示例，我们如何在不同的状态（例如按下、聚焦）为 LinearLayout 设置不同的颜色？
【解决方案6】：

现在我明白你的意思了。请看下面的例子

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:id="@+id/topField" android:layout_weight="2.5"
    android:layout_width="fill_parent" android:layout_height="fill_parent" 
    android:background="@drawable/topField_design" 
    android:orientation="horizontal" >
    <EditText android:id="@+id/digitsText" android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1" android:maxLines="1" android:scrollHorizontally="true"
        android:textSize="28sp" android:freezesText="true" android:background="#F7BE57"
        android:layout_margin="0dip"
        android:contentDescription="description"
        android:focusableInTouchMode="true" android:editable="true" android:cursorVisible="false" />
</LinearLayout>

现在“topField_design.xml”是一个drowable资源xml文件，包含drowable图像资源。

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" 
    android:drawable="@drawable/btn_dial_textfield_pressed" />
<item android:state_focused="true"
    android:drawable="@drawable/btn_dial_textfield_selected" />
<item
    android:drawable="@drawable/btn_dial_textfield_normal" />//btn_dial_textfield_normal is a .png image resource into drowable folder "btn_dial_textfield_normal.png"
</selector>
