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,
