问题描述

Android系统自带电池选项，如果设备没有电池功能，那么就要将系统中电池的选项移除掉，包括系统设置、状态栏、下拉菜单以及低电量报警弹框。

解决方法

1. 系统设置屏蔽电池选项

diff --git a/packages/apps/Settings/src/com/android/settings/SettingsActivity.java b/packages/apps/Settings/src/com/android/settings/SettingsActivity.javaindex 9047db9..b7fe5a9 100755--- a/packages/apps/Settings/src/com/android/settings/SettingsActivity.java+++ b/packages/apps/Settings/src/com/android/settings/SettingsActivity.java@@ -783,7 +783,7 @@ public class SettingsActivity extends SettingsDrawerActivity implements Preferen};mDevelopmentPreferences.registerOnSharedPreferenceChangeListener(mDevelopmentPreferencesListener);- registerReceiver(mBatteryInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));+ //registerReceiver(mBatteryInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));registerReceiver(mUserAddRemoveReceiver, new IntentFilter(Intent.ACTION_USER_ADDED));registerReceiver(mUserAddRemoveReceiver, new IntentFilter(Intent.ACTION_USER_REMOVED));@@ -798,7 +798,7 @@ public class SettingsActivity extends SettingsDrawerActivity implements Preferen@Overrideprotected void onStop() {super.onStop();- unregisterReceiver(mBatteryInfoReceiver);+ //unregisterReceiver(mBatteryInfoReceiver);unregisterReceiver(mUserAddRemoveReceiver);mDynamicIndexableContentMonitor.unregister();}@@ -1162,7 +1162,7 @@ public class SettingsActivity extends SettingsDrawerActivity implements Preferen}setTileEnabled(new ComponentName(packageName, Settings.PowerUsageSummaryActivity.class.getName()),-mBatteryPresent, isAdmin, pm);+false, isAdmin, pm);setTileEnabled(new ComponentName(packageName, Settings.UserSettingsActivity.class.getName()),UserHandle.MU_ENABLED && UserManager.supportsMultipleUsers() && !Utils.isMonkeyRunning(), isAdmin, pm);

2.隐藏状态栏电池图标

diff --git a/frameworks/base/packages/SystemUI/src/com/android/systemui/BatteryMeterView.java b/frameworks/base/packages/SystemUI/src/com/android/systemui/BatteryMeterView.javaindex d8b95cc..e50cdc9 100644--- a/frameworks/base/packages/SystemUI/src/com/android/systemui/BatteryMeterView.java+++ b/frameworks/base/packages/SystemUI/src/com/android/systemui/BatteryMeterView.java@@ -66,7 +66,7 @@ public class BatteryMeterView extends ImageView implementspublic void onTuningChanged(String key, String newValue) {if (StatusBarIconController.ICON_BLACKLIST.equals(key)) {ArraySet<String> icons = StatusBarIconController.getIconBlacklist(newValue);- setVisibility(icons.contains(mSlotBattery) ? View.GONE : View.VISIBLE);+ setVisibility(icons.contains(mSlotBattery) ? View.GONE : View.GONE);}}

3.隐藏低电量系统弹框

4.隐藏下拉菜单电池图标
