我想在图片中表达rssi：_____的rsing值。 我能够在日志上获得chasiing rssi值，就像图片一样。

您需要扫描intervall，＆＃34;刷新＆＃34; RSSI通过重新扫描设备。 STH。像这样：

public void scanLeDevice(final boolean enable)
{
    final static int SCAN_PERIOD = 2000; //2s
    final BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
    final BluetoothAdapter mBluetoothAdapter = bluetoothManager.getAdapter();

    //to start or stop scanning (true/false)
    if (enable)
    {
        // Stops scanning after a pre-defined scan period
        mHandler.postDelayed(new Runnable()
        {
            @Override
            public void run()
            {
                mBluetoothAdapter.stopLeScan(mLeScanCallback);
                if (mGatt == null)
                    offScan();
            }
        }, SCAN_PERIOD);

        mBluetoothAdapter.startLeScan(mLeScanCallback);

    }
    else
    {
        mBluetoothAdapter.stopLeScan(mLeScanCallback);
    }
}
