public void init() {     mLeftSide = mView.findViewById(R.id.notification_icon_area);     mStatusIcons = mView.findViewById(R.id.statusIcons);     mSignalCluster = mView.findViewById(R.id.signal_cluster);           mBattery = mView.findViewById(R.id.battery);     if (SystemProperties.get("persist.sys.batteryhide").equals("true"))     {                           mBattery.setVisibility(View.GONE);     }            mClock = mView.findViewById(R.id.clock);     applyModeBackground(-1, getMode(), false /*animate*/);     applyMode(getMode(), false /*animate*/); }

2.隐藏下拉的电池百分比的显示

VISIBLE : GONE);         //mBatteryLevel.setVisibility(mExpanded ? View.VISIBLE : View.GONE); 隐藏电池百分比        if(SystemProperties.get("persist.sys.batteryhide").equals("true")){               mBatteryLevel.setVisibility(View.GONE);        }else{            mBatteryLevel.setVisibility(View.VISIBLE);            }                  mMultiUserSwitch.setVisibility(View.VISIBLE);     } }
