對(duì)于簡(jiǎn)短的listview,加上如上面這些比較死的數(shù)據(jù)，我們完全沒(méi)有必要用listview來(lái)實(shí)現(xiàn)，TableLout完全夠了.主要是我們?cè)趺磳?shí)現(xiàn)帶有弧度的邊罷了，不過(guò)這也完全得力于shape的功勞，至于點(diǎn)擊效果效果嘛，我們有selector,下面介紹下實(shí)現(xiàn)：

配置文件部分代碼：

<ScrollViewandroid:layout_width="match_parent"android:layout_height="match_parent"android:scrollbars="none" ><LinearLayoutandroid: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>

很簡(jiǎn)單，我們主要用這個(gè)Linerlayout來(lái)呈放我們的Table.?

實(shí)現(xiàn)代碼：

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[] = { "天氣動(dòng)畫(huà)", "通知欄天氣" };private static final String MSG_2[] = { "桌面插件", "綁定微博", "天氣分享", "通知與提示","定時(shí)播報(bào)" };private static final String MSG_3[] = { "檢查新版本", "發(fā)送建議", "幫助", "關(guān)于" };@Overridepublic 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();}/**** 顯示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);}/**** 獲取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* 顯示信息* @param current_Id* 當(dāng)前個(gè)數(shù)* @param totle_Num* 總個(gè)數(shù)* @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);// 創(chuàng)建分割線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);// 只有一項(xiàng)if (totle_Num == 1) {view.setBackgroundResource(R.drawable.default_selector);return view;}// 第一項(xiàng)else if (current_Id == 0) {view.setBackgroundResource(R.drawable.list_top_selector);}// 最后一項(xiàng)else if (current_Id == totle_Num - 1) {view.setBackgroundResource(R.drawable.list_bottom_selector);line.setVisibility(View.GONE);} elseview.setBackgroundResource(R.drawable.list_center_selector);linearLayout.addView(view);linearLayout.addView(line);return linearLayout;} }

主要是getView有些復(fù)雜，不過(guò)都很好理解，相信大家都可以明白，只是沒(méi)有動(dòng)手做而已，小弟我只是想用這個(gè)練練手.?

不過(guò)不要忘記我們的背景實(shí)現(xiàn)
這個(gè)是只有一項(xiàng)的背景，
default_selector.xml

<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="[url=http://schemas.android.com/apk/res/android]http://schemas.android.com/apk/res/android[/url]"><item android:state_pressed="true"><shape><stroke android:width="1dp" android:color="@color/gray" /><solid android:color="@color/gray" /><corners android:radius="8dp" /></shape></item><item><shape><stroke android:width="1dp" android:color="@color/gray" /><solid android:color="@color/white" /><corners android:radius="8dp" /></shape></item> </selector>

主要就這么多了，下面我們來(lái)看下實(shí)現(xiàn)效果：
