做一个listActivity每行2个项目的工作

Question

我有麻烦设置我的listView上工作与列表中的每个项目的两个textViews。这是我的代码。我知道我尝试实现两个不同的阵列的方式存在根本性的错误，但我一直无法弄清楚。不确定hashMaps是否会走。

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，我真的想坚持SimpleAdapter。

酪氨酸这一

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，如果你使用

<?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>

如下图所示

使用自定义列表视图：

那么你必须使用BaseAdapter为， 这里是你的代码

public class MainActivity extends Activity 
{ 
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); 

    ListView listView= (ListView) findViewById(R.id.lv_list); 

    count = this.names.length(); 
    listView.setAdapter(new CustomAdapter(MainActivity.this)); 
} 

public class CustomAdapter extends BaseAdapter 
{ 
    /* 
    * Variables Declaration section 
    */ 
    private Context mContext; 

    public CustomAdapter(Context context) 
    { 
     mContext = context; 
    }//End of CustomAdapter constructor 

    public int getCount() 
    { 
     return count; 
    }//End of getCount method 

    public Object getItem(int position) 
    { 
     return position; 
    }//End of getItem method 

    public long getItemId(int position) 
    { 
     return position; 
    }//End of getItemId method 

    public View getView(int position, View convertView, ViewGroup parent) 
    { 
     ViewHolder holder; 

     if (convertView == null) 
     { 
      holder = new ViewHolder(); 

      convertView = LayoutInflater.from(mContext).inflate(R.layout.text_view, null); 
      holder.textviewName = (TextView) convertView.findViewById(R.id.name); 
      holder.textviewNumber = (TextView) convertView.findViewById(R.id.number); 

      convertView.setTag(holder); 
     }//End of if condition 
     else 
     { 
      holder = (ViewHolder) convertView.getTag(); 
     }//End of else 

     holder.textviewName.setText(names[position]); 
     holder.textviewNumber.setText(nums[position]); 

     return convertView; 
    }//End of getView method 
}//End of CustomAdapter instance inner class 

class ViewHolder 
{ 
    TextView textviewName; 
    TextView textviewNumber; 
}//End of ViewHolder instance inner class 
} 

您main.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:background="#FFFFFF" 
android:orientation="vertical" > 
<ListView 
     android:id="@+id/lv_list" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" > 
    </ListView> 
</LinearLayout> 

创建在名称text_view.xml

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

<TextView 
     android:id="@+id/name" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:text="TextView" 
     android:textColor="#00ccFF" 
     android:textSize="18sp" 
     android:paddingTop="10sp" 
     android:textStyle="normal" /> 

    <TextView 
     android:id="@+id/number" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignLeft="@+id/name" 
     android:layout_alignRight="@+id/name" 
     android:layout_toRightOf="@+id/icon" 
     android:layout_below="@+id/name" 
     android:text="TextView" 
     android:textColor="#00ccFF" 
     android:textSize="16sp" 
     android:paddingTop="30sp" 
     android:textStyle="normal" /> 
</RelativeLayout> 

这res/layout下一个xml会为你做这项工作。 Tweak the code for your purpose.感谢
