Android9.0 SystemUI 网络信号栏定制修改的流程解析

前情提要

Android 8.1平台SystemUI 导航栏加载流程解析

9.0 改动点简要说明

1、新增 StatusBarMobileView 替代 SignalClusterView，用以控制信号栏显示

同时增加的还有 StatusBarIconView、StatusBarWifiView

2、整体流程和 8.1 类似

效果图

整体流程图

上代码

先来看初始赋值的地方 MobileSignalController.java，在 notifyListeners() 方法中进行我们对应的定制，

最后通过 callback.setMobileDataIndicators() 将状态值传递到 StatusBarSignalPolicy.java 解析显示

vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\android\systemui\statusbar\policy\MobileSignalController.java

@Override

根据通用标准自定义显示规则

dbm >= -107 4格

-107 > dbm >= -111 3格

-111 > dbm >= -114 2格

-114 > dbm >= -117 1格

vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\android\systemui\statusbar\policy\TelephonyIcons.java

 static final int[] TELEPHONY_SIGNAL_STRENGTH_FULL = {

  R.drawable.stat_sys_signal_3_fully,
  R.drawable.stat_sys_signal_4_fully,
 };
 /**

 */
 static final int getSignalStrengthIcon(int level) {
 android.util.Log.e("ccz", "getSignalStrengthIcon() level=="+level);
 if (level >= 0 && level < TELEPHONY_SIGNAL_STRENGTH_FULL.length) {

 }
 return 0;
 }

舍弃原来的网络大图标，新增网络小图标，这样可以在下方显示网络数据图标

vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\mediatek\systemui\statusbar\networktype\NetworkTypeUtils.java

//cczheng add show small networkType

};
public static int getOperatorType(TelephonyManager telephonyManager) {

 String operator = telephonyManager.getSimOperator();
 switch (operator) {

StatusBarSignalPolicy 通过 description 传递运营商类型

vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\android\systemui\statusbar\phone\StatusBarSignalPolicy.java
@Override
 public void setMobileDataIndicators(IconState statusIcon, IconState qsIcon, int statusType,
  int networkType, int volteIcon, int qsType, boolean activityIn, boolean activityOut,
  String typeContentDescription, String description, boolean isWide, int subId,
  boolean roaming, boolean isDefaultData, int customizedState) {
 Log.i("ccz","StatusBarSignalPolicy setMobileDataIndicators()");
 MobileIconState state = getState(subId);
 if (state == null) {
  return;
 }
 .....
 //cczheng add for operator because description is unless
 state.mOperator = description;
 Log.e("ccz","mMobileStrengthId="+statusIcon.icon);
 // Always send a copy to maintain value type semantics
 mIconController.setMobileIcons(mSlotMobile, MobileIconState.copyStates(mMobileStates));
}
