Android系统移植与调试之------->如何修改Android默认字体大小和设置里面字体大小比例

           因为我修改 ro.sf.lcd_density的值，将它从160修改 为120，所以导致整个系统的字体都变得很小。因此需要将整个字体变大，并且在设置-->显示-->字体大小的4个选项的值都必须变大。我想到的思路是将字体的缩放比例调大一些，下面是我的修改步骤。

1、修改默认字体的大小

Step1: 修改frameworks/base/core/java/android/content/res/Configuration.java  

文件中的setToDefaults()方法，将默认的字体缩放比例调为1.35f，即修改fontScale属性

Public void setToDefaults(){
 fontScale=1.35f; //default value is 1
mcc = mnc = 0;
....
}

2、修改设置-->显示-->字体大小的4个选项值

Step2:  vim packages/apps/Settings/res/values/arrays.xml和

vim packages/apps/Settings/res/values-sw600dp/arrays.xml

下面就是4个选项对应的值，分别为 小、正常、大、超大

<pre class="html" name="code"><string-array name=”entryvalues_font_size” translatable=”false”>
<item>1.4</item>
<item>1.45</item>
<item>1.5</item>
<item>1.55</item>
</string-array>

Step3: 编译frameworks模块

./mk mbk77_twn_cu_jb mm frameworks/

Step4: 编译packages模块

./mk mbk77_twn_cu_jb mm packages/

Step5: 更新systemimage

./mk mbk77_twn_cu_jb systemimage

Step6:  将生成的文件copy到指定目录（Getimag.sh是个批处理文件，用来copy文件的，读者可以自己写）

./Getimag.sh 

Getimag.sh代码如下

#!/bin/sh

for project in "$@"
do
echo "客户名称 = $project"
done

project="mbk77_twn_cu_jb"
#echo "cust project is:" $project

rm -rf out/bin
mkdir out/bin

zip -r $project.zip *
mv $project.zip ../
echo "操作完成"
