Android5.1禁止状态栏下拉（SystemUI StatusBar）

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;
                }
             }

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;

                }
