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;

}

}
