ANDROID TEXTVIEW 设置字体颜色

用一下方法基本上可以解决大多数字体颜色设置问题，先发一篇，明天继续发一篇高级的，通过用户选择的方式，改变字体颜色。

TextView的字体设置方法：

1、直接通过配置文件设置

2、在Activity类中进行设置

<wbr></wbr>

第一种方式很简单，用于静态或初始文字颜色的设置，方法如下：

<wbr></wbr>

main.xml

<wbr><wbr></wbr></wbr>

Xml代码

<?xml<wbr></wbr>version="1.0"<wbr></wbr>encoding="utf-8"?><wbr><wbr></wbr></wbr>

<LinearLayout<wbr></wbr>xmlns:android="http://schemas.android.com/apk/res/android"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:orientation="vertical"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:layout_width="fill_parent"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:layout_height="fill_parent"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:background="@drawable/white"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>><wbr><wbr></wbr></wbr>

<TextView<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:id="@+id/tv01"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:layout_width="fill_parent"<wbr><wbr><wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:layout_height="wrap_content"<wbr><wbr><wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:text="@string/hello"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:autoLink="all"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:textColor="@color/red"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>/><wbr><wbr></wbr></wbr>

</LinearLayout><wbr><wbr></wbr></wbr>

<wbr>color.xml</wbr>

<wbr>Xml代码<a title="复制代码" href="http://blog.sina.com.cn/s/blog_3fe375b70100ns6r.html#" style="text-decoration:none; color:rgb(78,121,83)"></a></wbr>

<?xml<wbr></wbr>version="1.0"<wbr></wbr>encoding="utf-8"?><wbr><wbr></wbr></wbr>

<resources><wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr><color<wbr></wbr>name="red">#FF0000</color><wbr><wbr></wbr></wbr>

</resources><wbr><wbr></wbr></wbr>

drawable.xml

<wbr></wbr>

<wbr></wbr>

Xml代码

<?xml<wbr></wbr>version="1.0"<wbr></wbr>encoding="utf-8"?><wbr><wbr></wbr></wbr>

<resources><wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr><drawable<wbr></wbr>name="white">#FFFFFF</drawable><wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr><drawable<wbr></wbr>name="dark">#000000</drawable><wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr><drawable<wbr></wbr>name="red">#FF0000</drawable><wbr><wbr></wbr></wbr>

</resources><wbr><wbr></wbr></wbr>

strings.xml

<wbr></wbr>

<wbr></wbr>

Xml代码

<?xml<wbr></wbr>version="1.0"<wbr></wbr>encoding="utf-8"?><wbr><wbr></wbr></wbr>

<resources><wbr><wbr></wbr></wbr>

<wbr><wbr></wbr></wbr><string<wbr></wbr>name="hello">地址：http://yahaitt.javaeye.com</string><wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr><string<wbr></wbr>name="app_name">丫梨的笔记本</string><wbr><wbr></wbr></wbr>

</resources><wbr><wbr></wbr></wbr>

<wbr></wbr>

<wbr><wbr></wbr></wbr>

上面将资源部分分成了3个部分，目的是为了清晰，当然你也可以只建一个xml文件放在res目录下，而且文件名称可以随便命名。

<wbr></wbr>

注意两个地方：

1、main.xml的TextView标签中：

android:textColor="@color/red"

2、color.xml中：

<color name="red">#FF0000</color>

<wbr></wbr>

@color指获取资源文件中(所有res目录下的xml文件)的<color>标签

/red指在标签下找其name值为red的内容，此时其值为#FF0000

<wbr></wbr>

因此，这里我们还可以这样做：

android:textColor="@drawable/red"

<wbr></wbr>

@drawable指获取资源文件中<drawable>标签

/red指在标签下找其name值为red的内容

<wbr></wbr>

以此类推，相信你也就知道了如果是在strings.xml中该怎么做了。

<wbr></wbr>

<wbr></wbr>

<wbr></wbr>

<wbr></wbr>

下面看看第二种方式：在Activity类中进行设置

<wbr></wbr>

1、先将main.xml改成如下，即去掉android:textColor="@color/red"：

<wbr></wbr>

Xml代码

<?xml<wbr></wbr>version="1.0"<wbr></wbr>encoding="utf-8"?><wbr><wbr></wbr></wbr>

<LinearLayout<wbr></wbr>xmlns:android="http://schemas.android.com/apk/res/android"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:orientation="vertical"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:layout_width="fill_parent"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:layout_height="fill_parent"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:background="@drawable/white"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>><wbr><wbr></wbr></wbr>

<TextView<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:id="@+id/tv01"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:layout_width="fill_parent"<wbr><wbr><wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:layout_height="wrap_content"<wbr><wbr><wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:text="@string/hello"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>android:autoLink="all"<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>/><wbr><wbr></wbr></wbr>

</LinearLayout><wbr><wbr></wbr></wbr>

<wbr>2、修改Activity的onCreate方法，这里我的Activity是Study03_01，原始代码如下：</wbr>

<wbr></wbr>

<wbr></wbr>

Java代码

package<wbr>yahaitt.study03_01; <wbr><wbr></wbr></wbr></wbr>

<wbr><wbr></wbr></wbr>

import<wbr>android.app.Activity; <wbr><wbr></wbr></wbr></wbr>

import<wbr>android.os.Bundle; <wbr><wbr></wbr></wbr></wbr>

<wbr></wbr>

public<wbr></wbr>class<wbr>Study03_01<wbr></wbr></wbr>extends<wbr>Activity<wbr>{<wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>@Override<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>public<wbr></wbr>void<wbr>onCreate(Bundle<wbr>savedInstanceState)<wbr>{ <wbr><wbr></wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>super.onCreate(savedInstanceState); <wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>setContentView(R.layout.main); <wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr>} <wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr>

}<wbr><wbr></wbr></wbr>

<wbr></wbr>

第一步：获得文本控件TextView，取名为tv

<wbr></wbr>

第二步：通过TextView的setTextColor方法进行文本颜色的设置，这里可以有3种方式进行设置：

<wbr></wbr>

第1种：tv.setTextColor(android.graphics.Color.RED);//系统自带的颜色类

<wbr></wbr>

第2种：tv.setTextColor(0xffff00ff);//0xffff00ff是int类型的数据，分组一下0x|ff|ff00ff，0x是代表颜色整数的标记，ff是表示透明度，ff00ff表示颜色，注意：这里ffff00ff必须是8个的颜色表示，不接受ff00ff这种6个的颜色表示。

<wbr></wbr>

第3种：tv.setTextColor(this.getResources().getColor(R.color.red));//通过获得资源文件进行设置。根据不同的情况R.color.red也可以是R.string.red或者R.drawable.red，当然前提是需要在相应的配置文件里做相应的配置，如：

<color name="red">#FF0000</color>

<drawable name="red">#FF0000</drawable>

<string name="red">#FF0000</string>

<wbr></wbr>

<wbr></wbr>

详细的代码如下：

Java代码

package<wbr>yahaitt.study03_01; <wbr><wbr></wbr></wbr></wbr>

<wbr><wbr></wbr></wbr>

import<wbr>android.app.Activity; <wbr><wbr></wbr></wbr></wbr>

import<wbr>android.content.res.Resources; <wbr><wbr></wbr></wbr></wbr>

import<wbr>android.graphics.Color; <wbr><wbr></wbr></wbr></wbr>

import<wbr>android.os.Bundle; <wbr><wbr></wbr></wbr></wbr>

import<wbr>android.widget.TextView; <wbr><wbr></wbr></wbr></wbr>

<wbr><wbr></wbr></wbr>

public<wbr></wbr>class<wbr>Study03_01<wbr></wbr></wbr>extends<wbr>Activity<wbr>{ <wbr><wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr><wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>private<wbr>TextView<wbr>tv; <wbr><wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>@Override<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>public<wbr></wbr>void<wbr>onCreate(Bundle<wbr>savedInstanceState)<wbr>{ <wbr><wbr></wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>super.onCreate(savedInstanceState); <wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>setContentView(R.layout.main); <wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>tv<wbr>=<wbr>(TextView)</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>this.findViewById(R.id.tv01); <wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

//<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>tv.setTextColor(Color.RED);</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr><wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

//<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>tv.setTextColor(0xff000000);</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr><wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr><wbr><wbr></wbr></wbr>

<wbr><wbr></wbr></wbr>

<wbr><wbr><wbr><wbr>} <wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr>

}<wbr><wbr></wbr></wbr>

<wbr></wbr>

注：请切换相应的注释

<wbr></wbr>

<wbr></wbr>

通过在Activity类中设置文本颜色，我们可以实现文本颜色的动态化。如果想保持文本颜色静态不变的话，可以直接通过上一篇中讲的通过直接配置即可。
