1. 电池广播获取充电状态

// 电池状态
import static android.os.BatteryManager.EXTRA_STATUS;
// 未知
import static android.os.BatteryManager.BATTERY_STATUS_UNKNOWN;
// 充电中
import static android.os.BatteryManager.BATTERY_STATUS_CHARGING;
// 放电中
import static android.os.BatteryManager.BATTERY_STATUS_DISCHARGING;
// 未充电
import static android.os.BatteryManager.BATTERY_STATUS_NOT_CHARGING;
// 电池满
import static android.os.BatteryManager.BATTERY_STATUS_FULL;

    private  BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            if (null == intent) {
                return;
            }

            String action = intent.getAction();

            if (Intent.ACTION_BATTERY_CHANGED.equals(action)) {
                int status = intent.getIntExtra(EXTRA_STATUS, BATTERY_STATUS_UNKNOWN);
                ...

    private String getStatus(int status) {
        String result = getString(R.string.battery_status_unknown);

        switch (status) {
            case BATTERY_STATUS_FULL:
                result = getString(R.string.battery_status_full);// 充满电
                break;
            case BATTERY_STATUS_NOT_CHARGING:
                result = getString(R.string.battery_status_not_charging); // 未充电
                break;
            case BATTERY_STATUS_DISCHARGING:
                result = getString(R.string.battery_status_discharging);// 放电中
                break;
            case BATTERY_STATUS_CHARGING:
                result = getString(R.string.battery_status_charging);// 充电中
                break;
            case BATTERY_STATUS_UNKNOWN:// 未知
                break;
        }

        return result;
    }

2. 充电器类型

// 充电器类型
import static android.os.BatteryManager.EXTRA_PLUGGED;
// 充电器
import static android.os.BatteryManager.BATTERY_PLUGGED_AC;
// 其他
import static android.os.BatteryManager.BATTERY_PLUGGED_ANY;
// USB
import static android.os.BatteryManager.BATTERY_PLUGGED_USB;
// 无线充电
import static android.os.BatteryManager.BATTERY_PLUGGED_WIRELESS;


    private  BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            if (null == intent) {
                return;
            }

            String action = intent.getAction();

            if (Intent.ACTION_BATTERY_CHANGED.equals(action)) {
                int plugged = intent.getIntExtra(EXTRA_PLUGGED, BATTERY_PLUGGED_ANY);
                ...
                
    private String getPlugged(int plugged) {
        String result = getString(R.string.battery_plugged_any);

        switch (plugged) {
            case BATTERY_PLUGGED_ANY:
                // 其他
                break;
            case BATTERY_PLUGGED_AC:
                // 充电器
                result = getString(R.string.battery_plugged_ac);
                break;
            case BATTERY_PLUGGED_USB:
                // USB
                result = getString(R.string.battery_plugged_usb);
                break;
            case BATTERY_PLUGGED_WIRELESS:
                // 无线充电
                result = getString(R.string.battery_plugged_wireless);
                break;
        }

        return result;
    }

具体键值

    // values of the "plugged" field in the ACTION_BATTERY_CHANGED intent.
    // These must be powers of 2.
    /** Power source is an AC charger. */
    public static final int BATTERY_PLUGGED_AC = 1;
    /** Power source is a USB port. */
    public static final int BATTERY_PLUGGED_USB = 2;
    /** Power source is wireless. */
    public static final int BATTERY_PLUGGED_WIRELESS = 4;
    /** @hide */
    public static final int BATTERY_PLUGGED_ANY =
            BATTERY_PLUGGED_AC | BATTERY_PLUGGED_USB | BATTERY_PLUGGED_WIRELESS;

3. 获取电池是否充电接口

package com.android.settings.fuelgauge;

import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.BatteryManager;
import android.util.Log;

public class InonePowerSaveUtil {

    public static final boolean IS_CHARGE_DISABLE = true;

    public static boolean isChargingDisable(Context context) {
        return IS_CHARGE_DISABLE && isCharging(context);
    }

    public static boolean isCharging(Context context) {
        Intent batteryBroadcast = context.registerReceiver(null,
                new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
        // 0 means we are discharging, anything else means charging
        boolean isCharging = batteryBroadcast.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1) != 0;
        Log.d(InonePowerSaveUtil.class.getSimpleName(),"isCharging = " + isCharging );
        return isCharging;
    }
}
