时间:2021-12-14 16:09:24

5.1状态栏要禁止下拉请按如下方案修改:

PanelBar.java(alps\frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\phone)中的两个方法。


    public void startOpeningPanel(PanelView panel) {
       //begin 添加下面三行
    if(XXX){

           return;

        }

      //end
        if (DEBUG) LOG("startOpeningPanel: " + panel);
        mTouchingPanel = panel;
        mPanelHolder.setSelectedPanel(mTouchingPanel);
        for (PanelView pv : mPanels) {
            if (pv != panel) {
                pv.collapse(false /* delayed */);
            }
        }
    }



5.1如果 单独禁止锁屏界面状态栏要禁止下拉请按如下方案修改:
NotificationPanelView.java(alps/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone)中的两个方法。
(1)
private void setQsExpanded(boolean expanded) {
         //begin 添加下面四行
        if(mKeyguardShowing)                     
        {                                                   
              return;                                     
        }                                                  
         //end
        boolean changed = mQsExpanded != expanded;
        if (changed) {
            mQsExpanded = expanded;
            updateQsState();
            requestPanelHeightUpdate();
            mNotificationStackScroller.setInterceptDelegateEnabled(expanded);
            mStatusBar.setQsExpanded(expanded);
        }
    }

(2)
    private boolean shouldQuickSettingsIntercept(float x, float y, float yDiff) {
        if (!mQsExpansionEnabled) {
            return false;
        }
         //begin 将下面第一行替换成第二行
        View header = mKeyguardShowing ? mKeyguardStatusBar : mHeader;       
        View header = mHeader;
       //end                                                                     
        boolean onHeader = x >= header.getLeft() && x <= header.getRight()
                && y >= header.getTop() && y <= header.getBottom();
        if (mQsExpanded) {
            return onHeader || (mScrollView.isScrolledToBottom() && yDiff < 0) && isInQsArea(x, y);
        } else {
            return onHeader;
        }
    }
 
(3) private boolean onTouchEvent()
{
...
        if (!mQsExpandImmediate && mQsTracking) {
             //begin  添加下面红色的两行
             if(!mKeyguardShowing){                                   
                onQsTouch(event);
                if (!mConflictingQsExpansionGesture) {
                    return true;
                }
             }
             //end                      
        }
...
}



滑动锁屏状态下如何禁止下拉状态栏?

 

 

[SOLUTION]

 

JB/KK

滑动锁屏状态下状态栏可以下拉是google 4.0 默认的设计。如果要禁止此功能,请修改

 

请修改KeyguardViewMediator.java的adjustStatusBarLocked()方法,将

 

                if (isSecure() || !ENABLE_INSECURE_STATUS_BAR_EXPAND) {

                    // showing secure lockscreen; disable expanding.

                    flags |= StatusBarManager.DISABLE_EXPAND;

                }

 

修改为:

 

                if (isSecure() || ENABLE_INSECURE_STATUS_BAR_EXPAND) {

                    // showing secure lockscreen; disable expanding.

                    flags |= StatusBarManager.DISABLE_EXPAND;

                }
