在baseAdapter

Question

我创建了一个适配器，以在“自定义对话框”中显示扫描的设备。出现自定义对话框，但即使没有任何设备出现。 每当我检查logcat时，Bluetooth Le Scanner都会显示设备。 自定义对话框的代码如下

public class CustomDialog extends Dialog{

    private LeDeviceListAdapter mLeDeviceListAdapter;
    private BluetoothAdapter mBluetoothAdapter;
    private boolean mScanning;
    private Handler mHandler;
    private AppCompatButton Scan;
    private AppCompatButton Stop;
    Context mContext;
    TextView textStatus;
    BluetoothLeScanner mLeScanner;
    private static final int REQUEST_ENABLE_BT = 1;
    // Stops scanning after 10 seconds.
    private static final long SCAN_PERIOD = 10000;
    ProgressBar contentLoadingProgressBar;


    public CustomDialog(@NonNull Context context) {
        super(context);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.custom_dialog);

        contentLoadingProgressBar = (ProgressBar) findViewById(R.id.contentLoading);
        contentLoadingProgressBar.setVisibility(View.GONE);
        textStatus = findViewById(R.id.textStatus);
        textStatus.setVisibility(View.GONE);

        Scan = (AppCompatButton) findViewById(R.id.scanButton);

        Scan.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                contentLoadingProgressBar.setVisibility(View.VISIBLE);
                Scan.setVisibility(View.GONE);
                textStatus.setVisibility(View.VISIBLE);
                BlueteethManager.with(getContext()).scanForPeripherals(10000, blueteethDevices -> {
                    for (BlueteethDevice device : blueteethDevices) {
                        if (!TextUtils.isEmpty(device.getBluetoothDevice().getName())) {
                            mLeDeviceListAdapter.addDevice(device);
                            mLeDeviceListAdapter.notifyDataSetChanged();

                            Timber.d("%s - %s", device.getName(), device.getMacAddress());

                        }
                    }
                    contentLoadingProgressBar.setVisibility(View.GONE);
                    textStatus.setVisibility(View.GONE);
                    Scan.setVisibility(View.VISIBLE);
                });
            }
        });


        final BluetoothManager bluetoothManager =
                (BluetoothManager) getContext().getSystemService(Context.BLUETOOTH_SERVICE);
        mBluetoothAdapter = bluetoothManager.getAdapter();


    }



    // Adapter for holding devices found through scanning.
    private class LeDeviceListAdapter extends BaseAdapter {
        private ArrayList<BlueteethDevice> mLeDevices;
        private LayoutInflater mInflator;

        public LeDeviceListAdapter() {
            super();
            mLeDevices = new ArrayList<BlueteethDevice>();
            mInflator = getLayoutInflater();
        }

        public void addDevice(BlueteethDevice device) {
            if (!mLeDevices.contains(device)) {
                mLeDevices.add(device);
            }
        }

        public void clear() {
            mLeDevices.clear();
        }

        @Override
        public int getCount() {
            return mLeDevices.size();
        }

        @Override
        public Object getItem(int i) {
            return mLeDevices.get(i);
        }

        @Override
        public long getItemId(int i) {
            return i;
        }

        @Override
        public View getView(int i, View view, ViewGroup viewGroup) {
            CustomDialog.viewHolder viewHolder;
            // General ListView optimization code.
            if (view == null) {
                   view = mInflator.inflate(R.layout.custom_dialog, null);
                viewHolder = new CustomDialog.viewHolder();
                viewHolder.cardDevice=view.findViewById(R.id.cardDevice);
                viewHolder.deviceAddress = (TextView) view.findViewById(R.id.device_address);
                viewHolder.deviceName = (TextView) view.findViewById(R.id.device_name);
                view.setTag(viewHolder);
            } else {
                viewHolder = (CustomDialog.viewHolder) view.getTag();


            }

            BlueteethDevice device = mLeDevices.get(i);
            final String deviceName = device.getName();

            if (deviceName != null && deviceName.length() > 0)
                viewHolder.deviceName.setText(deviceName);
            else
                viewHolder.deviceName.setText("Unknown Device");
            viewHolder.deviceAddress.setText(device.getMacAddress());
            viewHolder.deviceAddress.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    device.connect(true, isConnected -> {
                        Timber.d("Is the peripheral connected? %s", Boolean.toString(isConnected));
                        if (isConnected){
                            Toast.makeText(mContext, "BLE device Connected", Toast.LENGTH_SHORT).show();
                            textStatus.setText("Connected");
                            textStatus.setVisibility(View.VISIBLE);
                            Scan.setVisibility(View.GONE);
                            contentLoadingProgressBar.setVisibility(View.GONE);

                        }
                        else {
                            Toast.makeText(mContext, "Failed to connect", Toast.LENGTH_SHORT).show();
                        }
                    });
                }
            });
            return view;
        }
    }


    static class viewHolder {
        TextView deviceName;
        TextView deviceAddress;
        CardView cardDevice;
    }
}

我正在使用第三方库扫描设备。尽管它可以正常工作，但是没有在定制对话框中显示任何设备名称或地址。 Layout Inflator是否对我或造成什么问题？
