最近一个项目需要获取android设备电池信息，稍微记录下。
所用的方法是使用广播被动接受的。详细代码见下：
- 首先声明四个变量
private SharedPreferences preferences;
private SharedPreferences.Editor editor;
private IntentFilter intentFilter;
private BatteryChangeReceiver batteryChangeReceiver;
- 初始化它们，并且进行注册
preferences = getSharedPreferences("data", MODE_PRIVATE);
editor = getSharedPreferences("data", MODE_PRIVATE).edit();
intentFilter = new IntentFilter();
intentFilter.addAction(Intent.ACTION_BATTERY_CHANGED);
batteryChangeReceiver = new BatteryChangeReceiver(editor);
registerReceiver(batteryChangeReceiver, intentFilter);
- BatteryChangeReceiver我单独注册了一个类用来进行操作
public class BatteryChangeReceiver extends BroadcastReceiver {
SharedPreferences.Editor editor;
public BatteryChangeReceiver(SharedPreferences.Editor editor) {
this.editor = editor;
}
@Override
public void onReceive(Context context, Intent intent) {
//获取电池状态
int batteryStatus = intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
switch (batteryStatus) {
case BatteryManager.BATTERY_STATUS_UNKNOWN:
editor.putString("batteryStatus", "BATTERY_STATUS_UNKNOWN");
break;
case BatteryManager.BATTERY_STATUS_CHARGING:
editor.putString("batteryStatus", "BATTERY_STATUS_CHARGING");
break;
case BatteryManager.BATTERY_STATUS_DISCHARGING:
editor.putString("batteryStatus", "BATTERY_STATUS_DISCHARGING");
break;
case BatteryManager.BATTERY_STATUS_NOT_CHARGING:
editor.putString("batteryStatus", "BATTERY_STATUS_NOT_CHARGING");
break;
case BatteryManager.BATTERY_STATUS_FULL:
editor.putString("batteryStatus", "BATTERY_STATUS_FULL");
break;
default:
break;
}
//获取电池的健康程度
int batteryHealth = intent.getIntExtra(BatteryManager.EXTRA_HEALTH, -1);
switch (batteryHealth) {
case BatteryManager.BATTERY_HEALTH_UNKNOWN:
editor.putString("batteryHealth", "BATTERY_HEALTH_UNKNOWN");
break;
case BatteryManager.BATTERY_HEALTH_GOOD:
editor.putString("batteryHealth", "BatteryManager.BATTERY_HEALTH_GOOD");
break;
case BatteryManager.BATTERY_HEALTH_OVERHEAT:
editor.putString("batteryHealth", "BatteryManager.BATTERY_HEALTH_OVERHEAT");
break;
case BatteryManager.BATTERY_HEALTH_DEAD:
editor.putString("batteryHealth", "BatteryManager.BATTERY_HEALTH_DEAD");
break;
case BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE:
editor.putString("batteryHealth", "BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE");
break;
case BatteryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE:
editor.putString("batteryHealth", "BatteryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE");
break;
case BatteryManager.BATTERY_HEALTH_COLD:
editor.putString("batteryHealth", "BatteryManager.BATTERY_HEALTH_COLD");
break;
default:
break;
}
//获取电池是否存在
boolean batteryPresent = intent.getBooleanExtra(BatteryManager.EXTRA_PRESENT, false);
editor.putString("batteryPresent", String.valueOf(batteryPresent));
//获取电池的当前电量和总电量
int batteryCurrent = intent.getExtras().getInt("level");// 获得当前电量
int batteryTotal = intent.getExtras().getInt("scale");// 获得总电量
editor.putString("batteryCurrent", String.valueOf(batteryCurrent));
editor.putString("batteryTotal", String.valueOf(batteryTotal));
//获取电池充电方式
int batteryPlugged = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
switch (batteryPlugged) {
case BatteryManager.BATTERY_PLUGGED_AC:
editor.putString("batteryPlugged", "BATTERY_PLUGGED_AC");//交流电
break;
case BatteryManager.BATTERY_PLUGGED_USB:
editor.putString("batteryPlugged", "BatteryManager.BATTERY_PLUGGED_USB");//USB充电
break;
case BatteryManager.BATTERY_PLUGGED_WIRELESS:
editor.putString("batteryPlugged", "BatteryManager.BATTERY_PLUGGED_WIRELESS");//无线充电
break;
default:
break;
}
//获取电池的电压
int batteryVoltage = intent.getIntExtra(BatteryManager.EXTRA_VOLTAGE, -1);
editor.putString("batteryVoltage", String.valueOf(batteryVoltage));
//获取电池的温度
int batteryTemperature = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE, -1);
editor.putString("batteryTemperature", String.valueOf(batteryTemperature));
//获取电池的技术
String batteryTechnology = intent.getStringExtra(BatteryManager.EXTRA_TECHNOLOGY);
editor.putString("batteryTechnology", batteryTechnology);
//提交
editor.apply();
}
}
