android lisetview的多列模版

在listview中，可以做出多列模版的效果，关键还是在listview的模版本，比如如下：

<LinearLayout android:id="@+id/relativeLayout1" android:layout_height="fill_parent" android:layout_width="fill_parent"xmlns:android="http://schemas.android.com/apk/res/android">    <TextView        android:id="@+id/FirstText"        android:layout_width="0dp"        android:layout_height="wrap_content"        android:text="First"        android:layout_weight="1">    </TextView>        <TextView        android:id="@+id/SecondText"        android:layout_width="0dp"        android:layout_height="wrap_content"        android:text="Second"        android:layout_weight="2">    </TextView>        <TextView        android:id="@+id/ThirdText"        android:layout_width="0dp"        android:layout_height="wrap_content"        android:text="Third"        android:layout_weight="1">    </TextView>        <TextView        android:id="@+id/FourthText"        android:layout_width="0dp"        android:layout_height="wrap_content"        android:text="Fourth"        android:layout_weight="1">    </TextView></LinearLayout>

listviewadapter.java:

public class listviewAdapter extends BaseAdapter{public ArrayList<HashMap<String,String>> list;Activity activity;public listviewAdapter(Activity activity, ArrayList<HashMap<String,String>> list) {super();this.activity = activity;this.list = list;}public int getCount() {// TODO Auto-generated method stubreturn list.size();}public Object getItem(int position) {// TODO Auto-generated method stubreturn list.get(position);}public long getItemId(int position) {// TODO Auto-generated method stubreturn 0;}private class ViewHolder {       TextView txtFirst;       TextView txtSecond;       TextView txtThird;       TextView txtFourth;  }  public View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stub// TODO Auto-generated method stubViewHolder holder;LayoutInflater inflater =  activity.getLayoutInflater();if (convertView == null){convertView = inflater.inflate(R.layout.listview_row, null);holder = new ViewHolder();holder.txtFirst = (TextView) convertView.findViewById(R.id.FirstText);holder.txtSecond = (TextView) convertView.findViewById(R.id.SecondText);holder.txtThird = (TextView) convertView.findViewById(R.id.ThirdText);holder.txtFourth = (TextView) convertView.findViewById(R.id.FourthText);convertView.setTag(holder);}else{holder = (ViewHolder) convertView.getTag();}HashMap<String, String> map = list.get(position);holder.txtFirst.setText(map.get(FIRST_COLUMN));holder.txtSecond.setText(map.get(SECOND_COLUMN));holder.txtThird.setText(map.get(THIRD_COLUMN));holder.txtFourth.setText(map.get(FOURTH_COLUMN));return convertView;}

主程序：

public class MultiColumnActivity extends Activity {private ArrayList<HashMap<String,String>> list;    public void onCreate(Bundle savedInstanceState)     {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        ListView lview = (ListView) findViewById(R.id.listview);        populateList();        listviewAdapter adapter = new listviewAdapter(this, list);        lview.setAdapter(adapter);    }        private void populateList() {    list = new ArrayList<HashMap<String,String>>();    HashMap<String,String> temp = new HashMap<String,String>();temp.put(FIRST_COLUMN,"Colored Notebooks");temp.put(SECOND_COLUMN, "By NavNeet");temp.put(THIRD_COLUMN, "Rs. 200");temp.put(FOURTH_COLUMN, "Per Unit");list.add(temp);HashMap<String,String> temp1 = new HashMap<String,String>();temp1.put(FIRST_COLUMN,"Diaries");temp1.put(SECOND_COLUMN, "By Amee Products");temp1.put(THIRD_COLUMN, "Rs. 400");temp1.put(FOURTH_COLUMN, "Per Unit");list.add(temp1);HashMap<String,String> temp2 = new HashMap<String,String>();temp2.put(FIRST_COLUMN,"Note Books and Stationery");temp2.put(SECOND_COLUMN, "By National Products");temp2.put(THIRD_COLUMN, "Rs. 600");temp2.put(FOURTH_COLUMN, "Per Unit");list.add(temp2);HashMap<String,String> temp3 = new HashMap<String,String>();temp3.put(FIRST_COLUMN,"Corporate Diaries");temp3.put(SECOND_COLUMN, "By Devarsh Prakashan");temp3.put(THIRD_COLUMN, "Rs. 800");temp3.put(FOURTH_COLUMN, "Per Unit");list.add(temp3);HashMap<String,String> temp4 = new HashMap<String,String>();temp4.put(FIRST_COLUMN,"Writing Pad");temp4.put(SECOND_COLUMN, "By TechnoTalaktive Pvt. Ltd.");temp4.put(THIRD_COLUMN, "Rs. 100");temp4.put(FOURTH_COLUMN, "Per Unit");list.add(temp4);}}
