Android4.2 & amp; android4.3 remove virtual buttons

After receiving the customer's request temporarily, you only need to retain the return virtual buttons and put them in the lower right corner. The collection layout was modified, and then the flat layout was required. Find the location at noon in the afternoon and share it with you:

File to be modified for mobile phone layout: frameworks/base/packages/SystemUI/res/layout/navigation_bar.xml

You need to modify the flat layout file. Frameworks/base/packages/SystemUI/res/layout-sw600dp/navigation_bar.xml

To cancel a button, make the following changes:

-Android: layout_width = "128dp" android: paddingStart = "25dp" android: paddingEnd = "25dp"

+ Android: layout_width = "0dp" android: paddingStart = "25dp" android: paddingEnd = "25dp"

Android: layout_height = "match_parent"
Android: src = "@ drawable/ic_sysbar_back"
Systemui: keyCode = "4"
Android: layout_weight = "0"
Systemui: glowBackground = "@ drawable/ic_sysbar_highlight"
Android: contentDescription = "@ string/accessibility_back"
/>

But I want to put it in the lower right corner. Because I am not familiar with android, I used an offset method,

Modify:

- -Android: layout_width = "match_parent"
-Android: layout_height = "match_parent"
-Android: layout_weight = "1"
-/>

Become:

+ + Android: layout_width = "3300"
+ Android: layout_height = "match_parent"
+ Android: layout_weight = "1"
+/>

Success.

To hide all the virtual buttons, add qemu. hw. mainkeys = 1 in build. prop. Build. prop is under the system directory of the compiled file system.
