Java Android Studio：在另一个活动屏幕上显示特定设备的RSSI

当我尝试为rssi设置文本视图时，我得到了-32768，我知道我得到这个数字是因为

MIN\u值

，但我一直无法找到正确的数字<代码>设备是发送到此

添加项

活动的额外设备。主要活动包括我的广播接收器和发现的设备列表。当您单击其中一个查找到的设备时，它将使用所选的

btDevice

加载

AddEntry

活动。我试图找到它在主要活动中的RSSI

添加条目活动的一部分

private BluetoothDevice device;
    private int deviceRssi;

    public static final String FILE_NAME = "SavedDevices.csv";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_entry);
        intent = getIntent();
        tDevice = (TextView) findViewById(R.id.tDevice);
        tAddress = (TextView) findViewById(R.id.tAddress);
        btAddDevice = (Button) findViewById(R.id.btAddDevice);
        btChangeName = (Button) findViewById(R.id.btChangeName);
        inName = (EditText) findViewById(R.id.inName);
        txSignal = (TextView) findViewById(R.id.txSignal);
        txSignalNum = (TextView) findViewById(R.id.txSignalNum);

        device = getIntent().getExtras().getParcelable("btDevice");
        btName = device.getName();
        btAddress = device.getAddress();
        deviceRssi = intent.getShortExtra(BluetoothDevice.EXTRA_RSSI,Short.MIN_VALUE);

        tDevice.setText(btName);
        tAddress.setText(btAddress);
        txSignalNum.setText("" + deviceRssi + "dBm");

我的一个广播接收器

private final BroadcastReceiver mBroadcastReceiver3 = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            final String action = intent.getAction();
            Log.d(TAG, "onReceive: ACTION FOUND");
            if(action.equals(BluetoothDevice.ACTION_FOUND)) {
                BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

                mBTDevices.add(device);
                Log.d(TAG, "onRecive: " + device.getName() + " : " + device.getAddress());
                mDeviceListAdapter = new DeviceListAdapter(context, R.layout.device_adapter_view, mBTDevices);
                lvNewDevices.setAdapter(mDeviceListAdapter);
            }
        }
    };

添加设备方法

public void openAddEntry(BluetoothDevice device) {
        Intent intent = new Intent(this, AddEntry.class);
        intent.putExtra("btDevice", device);
        startActivity(intent);
    }
