片段内容未显示

Question

我有两个片段。当我尝试从第一个更改第二个时，第二个片段中的调试器连接但内容未显示。我尝试添加和替换方法，但都是一样的。第二个内容没有改变。

FragmentManager fragmentManager = getFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

        RepairViewFragment fragment = new RepairViewFragment();
        fragmentTransaction.add(R.id.detailFragment, fragment);
        fragmentTransaction.commit();

感谢。

这是RepairViewFragment

的代码

public class RepairViewFragment extends Fragment implements OnClickListener {

//  private final static int REQUEST_ENABLE_BT = 1;
//  private final static int REQUEST_BT_SETTINGS = 2;

ProgressDialog myProgressDialog = null;
BluetoothAdapter mBluetoothAdapter = null;

ArrayList<MachineBT> Machines = new ArrayList<MachineBT>();

String BluetoothDevices = "";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);




}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);


    mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

    Button btn_cl = (Button)getView().findViewById(R.id.btn_client_automat);
    btn_cl.setOnClickListener(this);

    Button btn_own = (Button)getView().findViewById(R.id.btn_own_automat);
    btn_own.setOnClickListener(this);

    ImageButton img_back = (ImageButton)getView().findViewById(R.id.img_back);
    img_back.setOnClickListener(this);



}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.repair_layout, container, false);
    return view;
}

Answer 1

嗯，我认为你应该把你的代码放在片段的onCreateView部分，而不是放在activityCreated上，我知道在listfrags上使用了activityCreated，就像我的情况一样：D

Answer 2

尝试将您在onActivityCreated中编写的代码移动到onStart。
