java - fragment 布局问题

Question

当我将数据从activity传递到fragment时，我得到这个:

为什么 fragment 会重叠？我只需要选中复选框的 fragment 。

这是我传递数据时的代码:

Bundle bundle = new Bundle();
            bundle.putIntegerArrayList("oki", hm);
            bundle.putIntegerArrayList("okiquantitapizze", hm_quantitàpizze);

            System.out.println("PERO:" + bundle);
 MyListFragment2 myFragment = MyListFragment2.newInstance(hm,hm_quantitàpizze);
            FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
            transaction.replace(android.R.id.content, myFragment);
            transaction.commit();

我的列表 fragment 2:

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


        System.out.println("BUNDLES1 prima:" + bundle);

        bundle=getArguments();

        System.out.println("BUNDLES1 dopo:" + bundle);



        if (bundle != null) {
            strtext2 = bundle.getIntegerArrayList("daje");
            System.out.println("BUNDLES1 prima:" + strtext2);

            quantitàpizze2 = bundle.getIntegerArrayList("daje2");
            System.out.println("BUNDLES1 prima:" + quantitàpizze2);

        }

}




    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the custom_spinner_items for this fragment
        //super.onDestroy();


        SharedPreferences settings = getContext().getSharedPreferences("states", Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = settings.edit();
        editor.clear();
        editor.commit();


        ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_list_2_2, container, false);





        return rootView;


    }




    public static MyListFragment2 newInstance(ArrayList<Integer> hm, ArrayList<Integer> hm_quantitàpizze) {
        MyListFragment2 fragment = new MyListFragment2();
        Bundle args = new Bundle();
        args.putIntegerArrayList("daje", hm);
        args.putIntegerArrayList("daje2", hm_quantitàpizze);
        fragment.setArguments(args);
        return fragment;
    }

如果我放

android:background="@color/white"为:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/acab"
    android:layout_marginLeft="5dp"
    android:background="@color/white"

    >
    <ListView
        android:id="@+id/listvieww"
        android:layout_marginTop="120dp"
        android:layout_width="fill_parent"
        android:layout_height="match_parent">

    </ListView>




</FrameLayout>

我明白了:

Answer 1

你应该在 fragment 背景中使用一些颜色

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/acab"
    android:layout_marginLeft="5dp"
    android:background="@color/white">

    <ListView
        android:id="@+id/listvieww"
        android:layout_marginTop="120dp"
        android:layout_width="fill_parent"
        android:layout_height="match_parent">

    </ListView>




</FrameLayout>

我可以在这张图片中看到它没有重叠。
