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:" $project rm -rf out/bin mkdir out/bin cp -rf out/target/product/$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"
