cocos2dx-获取设备电池信息

一言加载中...

cocos内部是获取不到了，只能对应平台写相关方法，然后传递到cocos中。下面只介绍Android/iOS两个平台下电池电量信息及充电状态的实现。

// 电池信息监听
private BroadcastReceiver batteryReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        int level = intent.getIntExtra("level", 0);     //获取当前电量
        int scale = intent.getIntExtra("scale", 100);   //获取总电量
        int status = intent.getIntExtra("status", 0);   //获取充电状态
        batteryInfo.setText(level * 100/scale+"% :"+status);
        
        // 电池状态有如下几种
        //BatteryManager.BATTERY_STATUS_UNKNOWN      没有安装电池
        //BatteryManager.BATTERY_STATUS_CHARGING     正在充电
        //BatteryManager.BATTERY_STATUS_FULL:        已经充满
        //BatteryManager.BATTERY_STATUS_DISCHARGING: 放电中
        //BatteryManager.BATTERY_STATUS_NOT_CHARGING:未充电
    }
};

    @Override
    protected void onResume() {
        super.onResume();
        // 注册监听
        registerReceiver(batteryReceiver,new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
    }

    @Override
    protected void onPause() {
        super.onPause();
        // 移除监听
        unregisterReceiver(batteryReceiver);
    }

+(NSString *) getBatteryInfo{
    // 监听电池信息
    if(not [UIDevice currentDevice].isBatteryMonitoringEnabled){
        [UIDevice currentDevice].batteryMonitoringEnabled = true;
    }
    // 获取电池信息
    UIDeviceBatteryState battery_state = [UIDevice currentDevice].batteryState;
    CGFloat battery_level = [UIDevice currentDevice].batteryLevel;

    int state = 0;
    switch (battery_state) {
        case UIDeviceBatteryStateUnknown:
            state = 1;
            break;
        case UIDeviceBatteryStateCharging:  // 充电中
            state = 2;
            break;
        case UIDeviceBatteryStateUnplugged: // 放电中
            state = 3;
            break;
        case UIDeviceBatteryStateFull:      // 充满
            state = 5;
            break;
        default:
            state = 0;
            break;
    }
    NSString *result = [NSString stringWithFormat:@"%.02f,%d,%d", battery_level*100, 100, state];
    return result;
}

cocos端拿到数据后，只需要根据数据显示对应UI及刷新即可。

写博客不易，请我喝杯咖啡？
