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

主要就这么多了,下面我们来看下实现效果:
