通过 android 的电池广播，你可以拿到：
| 信息 | 说明 |
|---|---|
| 当前电量 level | 当前电量百分比 |
| 电量最大值 scale | 一般 100 |
| 是否在充电 | ac / usb / 无线充电 |
| 充电开始 / 充电结束 | 通过广播监听 |
| 电池健康状态 | good、overheat 等 |
| 电池温度 | 部分机型支持 |
android 推荐方式：
val batterymanager = context.getsystemservice(context.battery_service) as batterymanager val batterylevel = batterymanager.getintproperty(batterymanager.battery_property_capacity)
batterylevel 即为 0–100 的电量百分比
兼容 android 5–16。
android 使用以下广播：
class batteryreceiver(private val callback: (batteryevent) -> unit) : broadcastreceiver() {
override fun onreceive(context: context, intent: intent) {
when (intent.action) {
intent.action_power_connected -> {
callback(batteryevent.chargestart)
}
intent.action_power_disconnected -> {
callback(batteryevent.chargestop)
}
intent.action_battery_changed -> {
val level = intent.getintextra(batterymanager.extra_level, -1)
val scale = intent.getintextra(batterymanager.extra_scale, 100)
val status = intent.getintextra(batterymanager.extra_status, -1)
val ischarging = status == batterymanager.battery_status_charging ||
status == batterymanager.battery_status_full
val percent = level * 100 / scale
callback(batteryevent.batteryinfo(percent, ischarging))
}
}
}
}
sealed class batteryevent {
data object chargestart : batteryevent()
data object chargestop : batteryevent()
data class batteryinfo(val level: int, val ischarging: boolean) : batteryevent()
}val receiver = batteryreceiver { event ->
when (event) {
is batteryevent.chargestart -> log.d("battery", "开始充电")
is batteryevent.chargestop -> log.d("battery", "停止充电")
is batteryevent.batteryinfo -> log.d("battery", "电量=${event.level}%, 是否充电=${event.ischarging}")
}
}
val filter = intentfilter().apply {
addaction(intent.action_battery_changed)
addaction(intent.action_power_connected)
addaction(intent.action_power_disconnected)
}
registerreceiver(receiver, filter)public class batteryreceiver extends broadcastreceiver {
@override
public void onreceive(context context, intent intent) {
string action = intent.getaction();
if (intent.action_power_connected.equals(action)) {
log.d("battery", "开始充电");
} else if (intent.action_power_disconnected.equals(action)) {
log.d("battery", "停止充电");
} else if (intent.action_battery_changed.equals(action)) {
int level = intent.getintextra(batterymanager.extra_level, -1);
int scale = intent.getintextra(batterymanager.extra_scale, 100);
int status = intent.getintextra(batterymanager.extra_status, -1);
boolean ischarging = status == batterymanager.battery_status_charging ||
status == batterymanager.battery_status_full;
int percent = level * 100 / scale;
log.d("battery", "电量=" + percent + "% 是否充电=" + ischarging);
}
}
}注册：
intentfilter filter = new intentfilter(); filter.addaction(intent.action_battery_changed); filter.addaction(intent.action_power_connected); filter.addaction(intent.action_power_disconnected); registerreceiver(new batteryreceiver(), filter);
1.无需权限
获取电量/充电状态 不需要任何危险权限。
2.action_battery_changed 是粘性广播
不需要手动发送，一调用 registerreceiver() 就能拿到当前电量。
3.android 10–16 完全兼容
这些电池广播没有废弃，可直接用。
可以用：
val intent = context.registerreceiver(null, intentfilter(intent.action_battery_changed))
即可直接拿：
val level = intent?.getintextra(batterymanager.extra_level, -1) val status = intent?.getintextra(batterymanager.extra_status, -1)
