捆绑包返回NULL

问题描述

我将数据从“活动”转发到“片段”。但是，我无法通过getArguments()从包中检索数据。

这是我的“抽屉活动”代码：

case R.id.nav_home:
            Bundle bundle = new Bundle();
            bundle.putString("edttext","From Activity");
            // set Fragmentclass Arguments
            HomePageFragment homePageFragment = new HomePageFragment();
            homePageFragment.setArguments(bundle);
            getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,homePageFragment).commit();
            break;

这是我的Home Fragment代码：

public View onCreateView(@NonNull LayoutInflater inflater,@Nullable ViewGroup container,@Nullable Bundle savedInstanceState)
{
    Bundle bundle = getArguments();
    String strtext = bundle.getString("edttext");
    return inflater.inflate(R.layout.fragment_google_map,container,false);
}

解决方法

您可以尝试在onViewCreated（...）中检索它吗？

编辑活动代码-

 FragmentManager fragmentManager = getSupportFragmentManager();
      final FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
      final MyFragment myFragment = new MyFragment();

 Bundle b = new Bundle();
            b.putString("message",editText.getText().toString());
            myFragment.setArguments(b);
            fragmentTransaction.add(R.id.frameLayout,myFragment).commit();

编辑主片段-

Bundle bundle = getArguments();
      String message = bundle.getString("message");
      textView.setText(message);
