這篇文章給大家介紹Android監(jiān)聽(tīng)電池狀態(tài)實(shí)例代碼，對(duì)android監(jiān)聽(tīng)電池狀態(tài)相關(guān)知識(shí)感興趣的朋友一起學(xué)習(xí)吧

如果要監(jiān)聽(tīng)電池的狀態(tài)改變，需要?jiǎng)討B(tài)注冊(cè)：android.intent.action.BATTERY_CHANGED，收到Action后可以根據(jù)對(duì)應(yīng)的Key獲取你需要的信息，更詳細(xì)信息可以參考以下例子中的BatteryChangedReceiver類

具體代碼如下所示：

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();
@Override
protected 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;
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
unregisterReceiver(receiver);
super.onDestroy();
}
class BatteryChangedReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
final String action = intent.getAction();
if (action.equalsIgnoreCase(Intent.ACTION_BATTERY_CHANGED)) {
System.out
.println("BatteryChangedReceiver BATTERY_CHANGED_ACTION---");
// 當(dāng)前電池的電壓
int voltage = intent.getIntExtra(BatteryManager.EXTRA_VOLTAGE,
-1);
// 電池的健康狀態(tài)
int health = intent
.getIntExtra(BatteryManager.EXTRA_HEALTH, -1);
switch (health) {
case 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");
break;
default:
break;
}
// 電池當(dāng)前的電量, 它介于0和 EXTRA_SCALE之間
int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
// 電池電量的最大值
int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
// 當(dāng)前手機(jī)使用的是哪里的電源
int pluged = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED,
-1);
switch (pluged) {
case BatteryManager.BATTERY_PLUGGED_AC:
// 電源是AC charger.[應(yīng)該是指充電器]
System.out.println("BATTERY_PLUGGED_AC");
break;
case BatteryManager.BATTERY_PLUGGED_USB:
// 電源是USB port
System.out.println("BATTERY_PLUGGED_USB ");
break;
default:
break;
}
int status = intent
.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
switch (status) {
case BatteryManager.BATTERY_STATUS_CHARGING:
// 正在充電
System.out.println("BATTERY_STATUS_CHARGING ");
break;
case BatteryManager.BATTERY_STATUS_DISCHARGING:
System.out.println("BATTERY_STATUS_DISCHARGING ");
break;
case BatteryManager.BATTERY_STATUS_FULL:
// 充滿
System.out.println("BATTERY_STATUS_FULL ");
break;
case BatteryManager.BATTERY_STATUS_NOT_CHARGING:
// 沒(méi)有充電
System.out.println("BATTERY_STATUS_NOT_CHARGING ");
break;
case BatteryManager.BATTERY_STATUS_UNKNOWN:
// 未知狀態(tài)
System.out.println("BATTERY_STATUS_UNKNOWN ");
break;
default:
break;
}
// 電池使用的技術(shù)。比如，對(duì)于鋰電池是Li-ion
String technology = intent
.getStringExtra(BatteryManager.EXTRA_TECHNOLOGY);
// 當(dāng)前電池的溫度
int temperature = intent.getIntExtra(
BatteryManager.EXTRA_TEMPERATURE, -1);
System.out.println("voltage = " + voltage + " technology = "
+ technology + " temperature = " + temperature
+ " level = " + level + " scale = " + scale);
} else if (action.equalsIgnoreCase(Intent.ACTION_BATTERY_LOW)) {
// 表示當(dāng)前電池電量低
System.out
.println("BatteryChangedReceiver ACTION_BATTERY_LOW---");
} else if (action.equalsIgnoreCase(Intent.ACTION_BATTERY_OKAY)) {
// 表示當(dāng)前電池已經(jīng)從電量低恢復(fù)為正常
System.out
.println("BatteryChangedReceiver ACTION_BATTERY_OKAY---");
}
}
}
}

獲取apk和版本信息

private int getVerCode(Context context) {
int verCode = -1;
try {
verCode = context.getPackageManager().getPackageInfo(
"com.example.charginganimation", 0).versionCode;
} catch (NameNotFoundException e) {
e.printStackTrace();
}
return verCode;
}
private String getVerName(Context context) {
String verName = "";
try {
verName = context.getPackageManager().getPackageInfo(
"com.example.charginganimation", 0).versionName;
} catch (NameNotFoundException e) {
e.printStackTrace();
}
return verName;
}

以上代碼內(nèi)容是小編給大家介紹的android監(jiān)聽(tīng)電池狀態(tài)的實(shí)例代碼，本文寫的不好還請(qǐng)見(jiàn)諒，有好的意見(jiàn)歡迎給小編留言，我會(huì)及時(shí)給大家溝通的，謝謝大家一直以來(lái)對(duì)腳本之家網(wǎng)站的支持！
