Android system transplantation and debugging ------- & gt; how to modify the default font size of Android and set the font size ratio

Because I changed the ro. sf. LCD _density value from 160 to 120, the font of the entire system became very small. Therefore, you need to increase the font size, and the values of the four options in the settings --> display --> font size must be larger. The idea I thought of was to increase the font's Zoom ratio. below is my modification steps. 1. Modify the default font size. Step 1: Modify frameworks/base/core/java/android/content/res/Configuration. in the java file, the setToDefaults () method is used to adjust the default font scaling ratio to 1.35f, that is, to modify the fontScale attribute [java] Public void setToDefaults () {fontScale = 1.35f; // default value is 1 mcc = mnc = 0 ;....} 2. Modify Settings --> display --> four option values of the font size. Step 2: vim packages/apps/Settings/res/values/arrays. xml and vim packages/apps/Settings/res/values-sw600dp/arrays. the values of the four options are shown in xml, small, normal, large, and oversized [html] <pre name = "code" class = "html"> <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> </ pre> <br> Step 3: compile the frameworks module [html]. /mk mbk77_twn_cu_jb mm frameworks/Step4: Compile the packages module [html]. /mk mbk77_twn_cu_jb mm packages/Step5: Update systemimage [html]. /mk mbk77_twn_cu_jb systemimage Step6: copy the generated file to the specified directory (Getimag. sh is a batch file used to copy files. You can write it yourself.) [html]. /Getimag. sh
