FragmentPickFloor.java

......

@Override
public void onClick(View v) {
    switch(v.getId()) {
        case R.id.btnScan:
            if(spinFloor.performClick() && spinPartFloor.performClick()) {
                extras = new Bundle();
                spinFloorValue = spinFloor.getSelectedItem().toString();
                spinPartFloorValue = spinPartFloor.getSelectedItem().toString();
                extras.putString(Constants.FLOOR_KEY, spinFloorValue);
                extras.putString(Constants.FLOOR_PART_KEY, spinPartFloorValue);
                intent = new Intent(getContext(), MainActivity.class);
                intent.putExtras(extras);
                startActivity(intent);

                FragmentCreator.fragmentTransactionSetup(new FragmentFloor(), getFragmentManager(), FragmentFloor.class.getSimpleName());
            }
                break;
    }
}

FragmentCreator.java

public static void fragmentTransactionSetup(Fragment fragment,
                                            FragmentManager fragmentManager,
                                            String tag) {

    fragmentManager.executePendingTransactions();
    FragmentTransaction fragmentTransaction = fragmentManager
            .beginTransaction();
    fragmentTransaction.replace(R.id.fragment_container, fragment, tag);

    fragmentTransaction.addToBackStack(tag);
    fragmentTransaction.commit();
}

FragmentFloor.java

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

TouchView.java

public TouchView(Context context, AttributeSet attrs) {
    super(context, attrs);

        extras = ((MainActivity) getContext()).getIntent().getExtras();
        spinFloorValue = extras.getString(Constants.FLOOR_KEY);
        spinPartFloorValue = extras.getString(Constants.FLOOR_PART_KEY);
  }

TouchView在FragmentPickFloor中从微调器中选择的依赖关系值中显示不同的背景。

间接是的。您必须使用片段setArguments()方法将bundle参数作为参数传递给片段，然后将数据传递到onCreateView()中的自定义视图。

创建Fragment时，使用setArguments（）方法传递值。

FragmentFloor fragment = new FragmentFloor();
Bundle args = new Bundle();
args.putString(Constants.FLOOR_KEY, spinFloorValue);
args.putString(Constants.FLOOR_PART_KEY, spinPartFloorValue);
fragment.setArguments(args);

然后在你的片段......

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_floor, container, false);
    TouchView touchView = (TouchView)view.findViewById(R.id.touchView);

    touchView.setSpinFloorValue(getArguments().getString(Constants.FLOOR_KEY));
    touchView.setSpinPartFloorValue(getArguments().getString(Constants.FLOOR_PART_KEY));

    return view;
}

或者，您可以尝试使用getActivity().getIntent()

直接从片段访问活动的捆绑数据

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_floor, container, false);
    TouchView touchView = (TouchView)view.findViewById(R.id.touchView);

    extras = ((MainActivity) getContext()).getIntent().getExtras();
    touchView.setSpinFloorValue(extras.getString(Constants.FLOOR_KEY));
    touchView.setSpinPartFloorValue(extras.getString(Constants.FLOOR_PART_KEY));

    return view;
}

是否可以将值直接从Fragment传递到自定义视图？
