java - 使 listActivity 每行包含 2 个项目

Question

我在将 listView 设置为与列表中的每个项目使用两个 textView 时遇到问题。这是我的代码。我知道我尝试实现两个不同数组的方式存在根本性错误，但我一直无法弄清楚这一点。不确定 hashMaps 是否是正确的选择。

private String[] nums= { "One", "Two", "Three" };
private String[] names= { "HoneyComb", "JellyBean", "ICS" };


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    int[] ids = {android.R.id.text1, android.R.id.text2};
    SimpleAdapter<String> adapter = new SimpleAdapter(this, names,
            android.R.layout.simple_list_item_2, nums, ids);
    setListAdapter(adapter);

}

如果可能的话，我真的很想坚持使用 SimpleAdapter。

提一下这个

private String[] nums= { "One", "Two", "Three" };
private String[] names= { "HoneyComb", "JellyBean", "ICS" };


List<HashMap<String,String>> aList = new ArrayList<HashMap<String,String>>();

        for(int i=0;i<nums.lenght();i++){
            HashMap<String, String> hm = new HashMap<String,String>();
            hm.put("txt1",  nums[i]);
            hm.put("txt2", names[i]);
            aList.add(hm);
        }

        // Keys used in Hashmap
        String[] from = { "txt1","txt2" };

        // Ids of views in listview_layout
        int[] to = {R.id.txt1,R.id.txt2};

        // Instantiating an adapter to store each items
        // R.layout.listview_layout defines the layout of each item
        SimpleAdapter adapter = new SimpleAdapter(getActivity().getBaseContext(), aList, R.layout.listview_layout, from, to);

        setListAdapter(adapter);

}

listview_layout.xml 是

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >




        <TextView
            android:id="@+id/txt1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="15dp" />

        <TextView
            android:id="@+id/txt2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="10dp" />



</LinearLayout>
