Posted 2021-08-05 小zhong

代码如下：

IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatusIntent = registerReceiver(null, ifilter);
//如果设备正在充电，可以提取当前的充电状态和充电方式（无论是通过 USB 还是交流充电器），如下所示：

int status = batteryStatusIntent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
boolean isCharging = status == BatteryManager.BATTERY_STATUS_CHARGING ||
  		status == BatteryManager.BATTERY_STATUS_FULL;

int chargePlug = batteryStatusIntent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
boolean usbCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;
boolean acCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;
  
if (isCharging) {
    if (usbCharge) {
        Toast.makeText(MainActivity.this, "手机正处于USB连接！", Toast.LENGTH_SHORT).show();
        Log.i(TAG, "手机正处于USB连接！");
        charge = 1;
	} else if (acCharge) {
        Toast.makeText(MainActivity.this, "手机通过电源充电中！", Toast.LENGTH_SHORT).show();
        Log.i(TAG, "手机通过电源充电中");
        charge = 1;
    }
} else {
   Toast.makeText(MainActivity.this, "手机未连接USB线！", Toast.LENGTH_SHORT).show();
   Log.i(TAG, "手机未连接USB线！");
   charge = 0;
}
