如何获取当前单元格的信号强度？ [英] How to get current cell signal strength?

问题描述

我想存储单元格的信号强度，和我做这样的：

I would like to store the cell signal strength, and i do it like this:

private class GetRssi extends PhoneStateListener {
    @Override
    public void onSignalStrengthsChanged(SignalStrength signalStrength) {
        super.onSignalStrengthsChanged(signalStrength);
        Variables.signal = signalStrength.getGsmSignalStrength();


    }

}

好吧，但这只有当它改变运行。我需要的电流信号强度。

Okay but this only runs if it changes. I need the current signal strength.

有只问当前的信号强度的方法？

Is there a method to just ask for the current signal strength?

推荐答案

有getAllCellInfo（）在TelephonyManager方法添加API 17，可能是很好的解决方案。使用示例：

There is getAllCellInfo() method in TelephonyManager added in API 17 that could be good solution. Example of use:

TelephonyManager telephonyManager = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
// for example value of first element
CellInfoGsm cellinfogsm = (CellInfoGsm)telephonyManager.getAllCellInfo().get(0);
CellSignalStrengthGsm cellSignalStrengthGsm = cellinfogsm.getCellSignalStrength();
cellSignalStrengthGsm.getDbm();
