对于简短的listview,加上如上面这些比较死的数据，我们完全没有必要用listview来实现，TableLout完全够了.主要是我们怎么实现带有弧度的边罢了，不过这也完全得力于shape的功劳，至于点击效果效果嘛，我们有selector,下面介绍下实现：

配置文件部分代码：

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="none" >
        <LinearLayout
            android:id="@+id/ll_main"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:gravity="center"
            android:orientation="vertical"
            android:paddingLeft="10dp"
            android:paddingRight="10dp" >
        </LinearLayout>
    </ScrollView>

很简单，我们主要用这个Linerlayout来呈放我们的Table. 

实现代码：

package com.jj.corner;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
import android.R.color;
import android.app.Activity;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.view.Window;
import android.widget.ArrayAdapter;
import android.widget.LinearLayout;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.RelativeLayout;
import android.widget.SimpleAdapter;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;
public class MainActivity2 extends Activity {
 private LinearLayout ll_main;
 private TableLayout tableLayout;
 private LinearLayout.LayoutParams layoutParams;
 private static final String MSG_0[] = { "jjhappyforever" };
 private static final String MSG_1[] = { "天气动画", "通知栏天气" };
 private static final String MSG_2[] = { "桌面插件", "绑定微博", "天气分享", "通知与提示",
   "定时播报" };
 private static final String MSG_3[] = { "检查新版本", "发送建议", "帮助", "关于" };
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  requestWindowFeature(Window.FEATURE_NO_TITLE);
  setContentView(R.layout.main2);
  ll_main = (LinearLayout) findViewById(R.id.ll_main);
  showTable();
 }
 /***
  * 显示table
  */
 public void showTable() {
  layoutParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
    LayoutParams.WRAP_CONTENT);
  layoutParams.bottomMargin = 30;
  layoutParams.topMargin = 10;
  ll_main.addView(getTable(MSG_0), layoutParams);
  ll_main.addView(getTable(MSG_1), layoutParams);
  ll_main.addView(getTable(MSG_2), layoutParams);
  ll_main.addView(getTable(MSG_3), layoutParams);
 }
 /***
  * 获取Table
  * 
  * @param array
  * @return
  */
 public TableLayout getTable(String[] array) {
  tableLayout = new TableLayout(this);
  tableLayout.setLayoutParams(layoutParams);
  tableLayout.setStretchAllColumns(true);
  for (int i = 0; i < array.length; i++) {
   TableRow tableRow = new TableRow(this);
   View view = getView(array[i], i, array.length);
   tableRow.addView(view);
   tableLayout.addView(tableRow);
  }
  return tableLayout;
 }
 /****
  * 
  * @param msg
  *            显示信息
  * @param current_Id
  *            当前个数
  * @param totle_Num
  *            总个数
  * @return
  */
 public View getView(String msg, int current_Id, int totle_Num) {
  LinearLayout linearLayout = new LinearLayout(this);
  LinearLayout.LayoutParams layoutParams1 = new LinearLayout.LayoutParams(
    LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
  layoutParams1.height = 1;
  linearLayout.setOrientation(1);
  // 创建分割线
  View line = new View(this);
  line.setLayoutParams(layoutParams1);
  line.setBackgroundColor(getResources().getColor(R.color.black));
  View view = LayoutInflater.from(MainActivity2.this).inflate(
    R.layout.item, null);
  view.setBackgroundDrawable(new BitmapDrawable());
  view.setFocusable(true);
  view.setClickable(true);
  TextView textView = (TextView) view.findViewById(R.id.tv_list_item);
  textView.setText(msg);
  textView.setTextSize(20);
  // 只有一项
  if (totle_Num == 1) {
   view.setBackgroundResource(R.drawable.default_selector);
   return view;
  }
  // 第一项
  else if (current_Id == 0) {
   view.setBackgroundResource(R.drawable.list_top_selector);
  }
  // 最后一项
  else if (current_Id == totle_Num - 1) {
   view.setBackgroundResource(R.drawable.list_bottom_selector);
   line.setVisibility(View.GONE);
  } else
   view.setBackgroundResource(R.drawable.list_center_selector);
  linearLayout.addView(view);
  linearLayout.addView(line);
  return linearLayout;
 }
}

主要是getView有些复杂，不过都很好理解，相信大家都可以明白，只是没有动手做而已，小弟我只是想用这个练练手. 

不过不要忘记我们的背景实现
这个是只有一项的背景，
default_selector.xml

    <item><shape>

主要就这么多了，下面我们来看下实现效果：
