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 1mcc = 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/shfor project in "$@"doecho "客户名称 = $project"doneproject="mbk77_twn_cu_jb"#echo "cust project is:" $projectrm -rf out/binmkdir out/bincp -rf out/target/product/$project/boot.img out/bin/cp -rf out/target/product/$project/cache.img out/bin/cp -rf out/target/product/$project/DSP_BL out/bin/cp -rf out/target/product/$project/kernel out/bin/cp -rf out/target/product/$project/ramdisk.img out/bin/cp -rf out/target/product/$project/ramdisk-recovery.img out/bin/cp -rf out/target/product/$project/recovery.img out/bin/cp -rf out/target/product/$project/secro.img out/bin/cp -rf out/target/product/$project/system.img out/bin/cp -rf out/target/product/$project/userdata.img out/bin/cp -rf mediatek/misc/EBR1 out/bin/#cp -rf mediatek/source/misc/EBR2 out/bin/cp -rf mediatek/misc/MBR out/bin/cp -rf mediatek/misc/*MT6577_Android_scatter_emmc.txt out/bin/cp -rf kernel/out/kernel_$project.bin out/bin/cp -rf bootable/bootloader/lk/build-$project/logo.bin out/bin/cp -rf mediatek/preloader/preloader_$project.bin out/bin/cp -rf bootable/bootloader/lk/build-$project/lk.bin out/bin/cp -rf mediatek/cgen/APDB_MT6577_S01_MAIN2.1_W10.24_ENUM out/bin/cp -rf mediatek/cgen/APDB_MT6577_S01_MAIN2.1_W10.24 out/bin/cp -rf mediatek/custom/common/modem/keytak15_atv_gb2_gprs/BPLGUInfoCustomApp_MT6577_S00_MAUI_11AMD_W12_22_SP_V27 out/bin/cd out/bin/zip -r $project.zip *mv $project.zip ../echo "操作完成"
