Android 将数据发送到来自同一活动的两个片段是一个好主意吗？

下面是活动代码的快照。我想把这些列表发送到不同的片段。第一个很好，但是在stepsFragment.setArgumentsstepsBundle中；无法识别setArguments。多谢各位

//
// Send the ingredients array list in Parcelable to the Ingredients Fragment
//
private void sendArrayToIngredientsFragment() {
    //Pack Data in a bundle(call the bundle "ingredientsBundle" to differentiate it from the "stepsBundle"
    Bundle ingredientsBundle = new Bundle();
    ingredientsBundle.putParcelable("Recipes", recipes);

    //Pass Over the bundle to the Ingredients Fragment
    IngredientsFragment ingredientsFragment = new IngredientsFragment();
    ingredientsFragment.setArguments(ingredientsBundle);

    getSupportFragmentManager().beginTransaction().replace(R.id.ingredients_fragment_container, ingredientsFragment).commit();
}

/*
  Send the steps array list in Parcelable to the Steps Fragment
  */
private void sendArrayToStepsFragment() {
    //Pack Data in a bundle(call the bundle "stepsBundle" to differentiate it from the "ingredientsBundle"
    Bundle stepsBundle = new Bundle();
    stepsBundle.putParcelable("Recipes", recipes);

    //Pass Over the bundle to the Steps Fragment
    StepsFragment stepsFragment = new StepsFragment();
    stepsFragment.setArguments(stepsBundle);

    getSupportFragmentManager().beginTransaction().replace(R.id.steps_fragment_container, stepsFragment).commit();
}

请确保，您的片段类都是从片段类扩展而来的。如果是这样，则必须存在方法setArguments

stepsFragment.setArguments有什么问题？是的，您可以将数据传递到片段。建议在fragment类本身中创建一个静态方法，即public static fragment newInstance{fragment=；Bundle Bundle=new Bundle；//将数据添加到Bundle fragment.setArgumentsbundle；返回fragment；}消息是：setArguments未被识别。如果您尚未找到答案，发布StepsFragmentThank的代码可能会有所帮助。我已经弄明白了。
