java - 如何将数据从 Activity 传递到 Fragment？

Question

关于将数据 Activity 传递给 Fragment 有很多问题。

但是我对“替换”方法有疑问。由于滑动 tablayout，我使用 fragment 。

我想从Character1_activity.java -> TabFragment1.java传递数据

这是代码。

Character1_Activity.java

public class Character1_Activity extends Activity implements View.OnClickListener {
    public String food_box;
    public String water_box;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
        layoutParams.flags = WindowManager.LayoutParams.FLAG_DIM_BEHIND;
        layoutParams.dimAmount = 0.7f; // 흐린 정도
        getWindow().setAttributes(layoutParams);
        setContentView(R.layout.character1);
    }

    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.closebutton1:
                Intent intent = new Intent(this, Next_day.class);
                CheckBox food = (CheckBox) findViewById(R.id.food_cb);
                CheckBox water = (CheckBox) findViewById(R.id.water_cb);

                if (food.isChecked() == true)
                    food_box = "true";
                else
                    food_box = "false";

                if (water.isChecked() == true)
                    water_box = "true";
                else
                    water_box = "false";

                TabFragment1 fragment = new TabFragment1();
                if (fragment != null) {
                    FragmentManager fragmentManager = getFragmentManager();
                    Bundle bundle = new Bundle();
                    bundle.putString("food_box", food_box);
                    fragment.setArguments(bundle);
                    fragmentManager.beginTransaction().replace(R.id.game_main, fragment).addToBackStack(null).commit();
                }
                this.finish();
                break;

这是 TabFragment1

public class TabFragment1 extends Fragment {
    String ch1_water;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.tab_fragment_1, container, false);
        getArguments().getString("water_box");
    }

来自 Activity :-

Bundle bundle = new Bundle();
bundle.putString("food_box", foodbox);
fragment.setArguments(bundle);

Fragment onCreateView方法:

    String strtext = getArguments().getString("food_box");
