Android9.0 SystemUI 网络信号栏定制修改的流程解析

移动开发 得得之家
这篇文章主要介绍了Android9.0 SystemUI 网络信号栏定制修改的流程，本文通过图文实例代码给大家介绍的非常详细，具有一定的参考借鉴价值,需要的朋友可以参考下

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_0_fully,
  R.drawable.stat_sys_signal_1_fully,
  R.drawable.stat_sys_signal_2_fully,
  R.drawable.stat_sys_signal_3_fully,
  R.drawable.stat_sys_signal_4_fully,
 };
 /**
 * Customize Signal strength icon.
 * @param level telephony signal strength leve.
 * @return Signal strength icon id.
 */
 static final int getSignalStrengthIcon(int level) {
 android.util.Log.e("ccz", "getSignalStrengthIcon() level=="+level);
 if (level >= 0 && level < TELEPHONY_SIGNAL_STRENGTH_FULL.length) {
  return TELEPHONY_SIGNAL_STRENGTH_FULL[level];
 }
 return 0;
 }
 static final int getSignalStrengthIcon(int dbm, int asu) {
 int level = 0;
 if(dbm >= -107) level = 4;
 else if (dbm >= -111) level = 3;

 }

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

 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,

  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));
}
