How to change jb lockscreen to this?

1. I want to remove white bounding box.
2. I want to move up the clock over widget boundary.
In ICS, there is a way to move clock upside.
By modifying keyguard_screen_unlock_portrait.xml file in framework-res.apk.
But in JB this method doesn't work well.
ps. I don't want to do this by 3rd party app like widget locker.

I may found a clue
I found a code about keyguard widget frame.
Code:
KeyguardWidgetFrame.java
public KeyguardWidgetFrame(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
mLongPressHelper = new CheckLongPressHelper(this);
Resources res = context.getResources();
// TODO: this padding should really correspond to the padding embedded in the background
// drawable (ie. outlines).
float density = res.getDisplayMetrics().density;
int padding = (int) (res.getDisplayMetrics().density * 8);
setPadding(padding, padding, padding, padding);
mFrameStrokeAdjustment = 2 + (int) (2 * density);
// This will be overriden on phones based on the current security mode, however on tablets
// we need to specify a height.
mSmallWidgetHeight =
res.getDimensionPixelSize(com.android.internal.R.dimen.kg_small_widget_height);
mBackgroundDrawable = res.getDrawable(R.drawable.kg_widget_bg_padded);
mGradientColor = res.getColor(com.android.internal.R.color.kg_widget_pager_gradient);
mGradientPaint.setXfermode(sAddBlendMode);
}
If I can change following line or remove it. It will solve my problem.
setPadding(padding, padding, padding, padding);
I also decompiled android.policy.jar.
And found corresponding line.
Code:
.line 110
.local v1, padding:I
invoke-virtual {p0, v1, v1, v1, v1}, Lcom/android/internal/policy/impl/keyguard/KeyguardWidgetFrame;->setPadding(IIII)V
But I don't have knowledge of smali.
So how to manage that line?
Is is safe to remove or change to this?
invoke-virtual {p0, 0, 0, 0, 0}

I finally solved problem!
It took some hours to solve this.
So I put these information for someone who want to change JB lockscreen like me.
1. Increase widget maximum size.
Decompile framework-res.apk
In \res\layout-port\
Modify keyguard_widget_pager.xml
Change left, right, top padding and pageSpacing as follows.
Code:
<?xml version="1.0" encoding="utf-8"?>
<com.android.internal.policy.impl.keyguard.KeyguardWidgetPager
android:id="@id/app_widget_container" android:paddingLeft="[COLOR="red"]0dip[/COLOR]"
android:paddingTop="[COLOR="red"]0dip[/COLOR]" android:paddingRight="[COLOR="Red"]0dip[/COLOR]"
android:paddingBottom="@dimen/kg_widget_pager_bottom_padding"
android:clipToPadding="false" android:pageSpacing="[COLOR="red"]0dip[/COLOR]"/>
2. Disable initial page hint
Decompile android.policy.jar
in com\android\internal\policy\impl\keyguard\KeyguardViewStateManager.smali
Remove following red string.
Code:
.method public showUsabilityHints()V
...
.line 307
iget-object v0, p0, Lcom/android/internal/policy/impl/keyguard/KeyguardViewStateManager;->mKeyguardWidgetPager:Lcom/android/internal/policy/impl/keyguard/KeyguardWidgetPager;
[COLOR="Red"]invoke-virtual {v0}, Lcom/android/internal/policy/impl/keyguard/KeyguardWidgetPager;->showInitialPageHints()V[/COLOR]
...
.end method
3. Disable white box while scrolling
Decompile android.policy.jar
in com\android\internal\policy\impl\keyguard\
Modify KeyguardWidgetPager.smali
Change red string to green one as follows
Code:
.method animateOutlinesAndSidePages(ZI)V
...
.line 708
[COLOR="Red"].local v7, finalOutlineAlpha:F[/COLOR]
:goto_4e
invoke-virtual {v3, p0, p1, v7, p2}, Lcom/android/internal/policy/impl/keyguard/KeyguardWidgetFrame;->fadeFrame(Ljava/lang/Object;ZFI)V
...
.end method
Code:
.method animateOutlinesAndSidePages(ZI)V
...
.line 708
[COLOR="Lime"]const/4 v7, 0x0[/COLOR]
:goto_4e
invoke-virtual {v3, p0, p1, v7, p2}, Lcom/android/internal/policy/impl/keyguard/KeyguardWidgetFrame;->fadeFrame(Ljava/lang/Object;ZFI)V
...
.end method
4. Disable page hint when dragging beyond first or last page
Decompile android.policy.jar
in com\android\internal\policy\impl\keyguard\
Modify KeyguardWidgetPager.smali
Remove red string in the follwing.
Code:
.method protected screenScrolled(I)V
...
.line 533
invoke-static {v5}, Ljava/lang/Math;->abs(F)F
move-result v9
cmpg-float v7, v5, v10
if-gez v7, :cond_61
const/4 v7, 0x1
:goto_51
[COLOR="Red"]invoke-virtual {v6, v9, v7}, Lcom/android/internal/policy/impl/keyguard/KeyguardWidgetFrame;->setOverScrollAmount(FZ)V[/COLOR]
...
.end method
5. (similar to 4 but) Only disable white gradiant
Decompile android.policy.jar
in com\android\internal\policy\impl\keyguard\
Modify KeyguardWidgetFrame.smali
Change red string to green one.
Code:
.method setOverScrollAmount(FZ)V
...
.line 497
const/high16 v1, 0x3f00
mul-float/2addr v1, p1
const/high16 v2, 0x437f
mul-float/2addr v1, v2
[COLOR="Red"] invoke-static {v1}, Ljava/lang/Math;->round(F)I
move-result v1[/COLOR]
iput v1, p0, Lcom/android/internal/policy/impl/keyguard/KeyguardWidgetFrame;->mForegroundAlpha:I
...
.end method
Code:
.method setOverScrollAmount(FZ)V
...
.line 497
const/high16 v1, 0x3f00
mul-float/2addr v1, p1
const/high16 v2, 0x437f
mul-float/2addr v1, v2
[COLOR="Lime"]const/4 v1, 0x0[/COLOR]
iput v1, p0, Lcom/android/internal/policy/impl/keyguard/KeyguardWidgetFrame;->mForegroundAlpha:I
...
.end method
6. Only show bounding box boarder
In framework-res.apk
Modify kg_bouncer_bg_white.9.png as follows

I'm not doing these things anymore.
And currently my phone is not jelly bean, I went back to ginger bread long time ago.
And I got a job, don't have time to do this, and I have no plan to do this.
Sorry.
