[Verizon Samsung Galaxy S III] Didact74:
Here is a time and am/pm toggle.

As always feel free to use these MODs with your ROM but since it took a few days to get this coded correctly just give me some thanks and some credit in your thread please.

[Q] What does this MOD do?

[A] It allows you to toggle off the TIME, the AM/PM, or both with toggles located in settings/date/time options

Here are the goodies.....

We will be working with two files.

-SecSettings

-SystemUI.apk

As always, I will assume you know how to compile/decompile so I will not be providing information how to do that.

Lets begin with SystemUI

Navigate to smali/com/android/systemui/statusbar/policy/clock.smali

This part is optional. This will make your AM/PM small or lowercase.

Find the following code

.method public constructor <init>(Landroid/content/Context;Landroid/util/AttributeSet;I)V
.locals 3
.parameter "context"
.parameter "attrs"
.parameter "defStyle"

.prologue
const/4 v2, [B]0x1 = small am/pm
0x0 = regular size am/pm[/B]

Find the following code

.method private final getSmallTime()Ljava/lang/CharSequence;

Replace the entire method with the following code

.method private final getSmallTime()Ljava/lang/CharSequence;
.locals 22

In the first section of code you will see an ID highlighted in RED. This is the CLOCK ID. Make sure this ID matches your CLOCK ID located in res/values/public of SystemUI

I know its a lot of code but to single out each change would take too long. Feel free to Diff out the individual changes if you want.

Navigate to smali/com/android/systemui/statusbar/phone/PhoneStatusBar.smali
