Android Battery Status Monitor

If you want to monitor battery status changes, you need to register dynamically: Android.intent.action.BATTERY_CHANGED, after receiving the action, you can obtain the information you need according to the corresponding key. For more information, refer to the Batterychangedreceiver class in the following example

Package Com.example.charginganimation;import Android.app.activity;import Android.content.broadcastreceiver;import Android.content.context;import Android.content.intent;import Android.content.intentfilter;import Android.os.batterymanager;import Android.os.bundle;import Android.view.view;public class MainActivity extends Activity {private customcliploading ccl;private batterychangedreceiver receiver = new Batterychangedreceiver (); overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview ( R.layout.main); Registerreceiver (receiver, GetFilter ());} Private Intentfilter GetFilter () {intentfilter filter = new Intentfilter (); Filter.addaction (Intent.action_battery_ CHANGED); filter.addaction (Intent.action_battery_low); filter.addaction (Intent.action_battery_okay); return filter ;} @Overrideprotected void OnDestroy () {//TODO auto-generated Method Stubunregisterreceiver (receiver); Super.ondestroy () ;} Class Batterychangedreceiver extends Broadcastreceiver{@Overridepublic void OnReceive (context context, Intent Intent) {//TODO auto-generated method stubfinal String action = i Ntent.getaction (); if (Action.equalsignorecase (intent.action_battery_changed)) {System.out.println (" Batterychangedreceiver battery_changed_action---");//current battery voltage int voltage = Intent.getintextra (Batterymanager.extra_ VOLTAGE,-1),///battery Health int. = Intent.getintextra (Batterymanager.extra_health,-1); BatteryManager.BATTERY_HEALTH_COLD:System.out.println ("Battery_health_cold"); Break;case Batterymanager.battery_ HEALTH_DEAD:System.out.println ("Battery_health_dead"); Break;case Batterymanager.battery_health_good: System.out.println ("Battery_health_good"); Break;case BatteryManager.BATTERY_HEALTH_OVERHEAT:System.out.println ( "Battery_health_overheat"); Break;case BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE:System.out.println ("Battery_ Health_cold "); Break;case BatteryManager.BATTERY_HEALTH_UNKNOWN:System.out.println (" Battery_health_unknown "); Break;case BattEryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE:System.out.println ("Battery_health_unspecified_failure"); Default:break;} The current power of the battery, which is between 0 and Extra_scale int level = Intent.getintextra (Batterymanager.extra_level,-1);//The maximum value of the battery charge int scale = inte Nt.getintextra (Batterymanager.extra_scale,-1);//Where the current phone is using the power int pluged = Intent.getintextra (Batterymanager.extra _PLUGGED,-1), switch (pluged) {Case batterymanager.battery_plugged_ac://power supply is AC charger.[ Should refer to the Charger]system.out.println ("Battery_plugged_ac"); Break;case batterymanager.battery_plugged_usb://power supply is USB PortSystem.out.println ("Battery_plugged_usb"); break;default:break;} int status = Intent.getintextra (Batterymanager.extra_status,-1); switch (status) {case Batterymanager.battery_status_ CHARGING://is charging System.out.println ("battery_status_charging"); Break;case Batterymanager.battery_status_ DISCHARGING:System.out.println ("battery_status_discharging"); Break;case batterymanager.battery_status_full:// Full of System.out.println ("Battery_status_full"); BREak;case batterymanager.battery_status_not_charging://no charge System.out.println ("battery_status_not_charging"); Break;case batterymanager.battery_status_unknown://Unknown State System.out.println ("Battery_status_unknown"); Default:break;} Technology for battery use.
