表格类似Excel

只是很简单的实现表格，使用GridView控件——>可以上下左右滚动，但是不能合并


直接上代码：
1、主要布局
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3.     android:layout_width="match_parent"
  4.     android:layout_height="match_parent"
  5.     android:orientation="vertical">
  6.     
  7.     <TextView 
  8.         android:id="@+id/textview"
  9.         android:layout_width="match_parent"
  10.         android:layout_height="wrap_content"
  11.         android:text="测试表格"/>
  12.     
  13.     <HorizontalScrollView 
  14.         android:layout_width="match_parent" 
  15.         android:layout_height="wrap_content"> 
  16.         <LinearLayout 
  17.             android:layout_width="match_parent" 
  18.             android:layout_height="wrap_content" 
  19.             android:orientation="vertical" > 
  20.             <GridView 
  21.                 android:id="@+id/table_grid"
  22.                 android:layout_width="match_parent"
  23.                 android:layout_height="match_parent"
  24.                 android:horizontalSpacing="1dp"
  25.                 android:verticalSpacing="1dp"
  26.                 android:numColumns="12">
  27.             </GridView> 
  28.         </LinearLayout> 
  29.     </HorizontalScrollView>
  31. </LinearLayout>
2、表格中一个item的布局
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3.     android:layout_width="80dp"
  4.     android:layout_height="match_parent"
  5.     android:orientation="vertical">
  6.     
  7.     <TextView 
  8.         android:id="@+id/text_item"
  9.         android:layout_width="wrap_content"
  10.         android:layout_height="wrap_content"
  11.         android:gravity="center"
  12.         android:layout_gravity="center"
  13.         android:textSize="15dp"
  14.         android:textColor="#000000"></TextView>
  15.     
  17. </LinearLayout>

3、Adapter代码
  1. package com.example.achartenginetest.adapter;
  3. import java.util.ArrayList;
  4. import java.util.List;
  6. import android.content.Context;
  7. import android.graphics.Color;

  9. import android.view.View;
  10. import android.view.ViewGroup;
  11. import android.widget.BaseAdapter;
  12. import android.widget.TextView;
  14. import com.example.achartenginetest.R;
  16. public class TableAdapter extends BaseAdapter {
  17.     private final static int NUM_COLUMN = 12;
  18.     
  19.     private LayoutInflater mInflater;
  20.     private List<double[]> mOriginalData;
  21.     private List<String> mData;
  22.     private Context mContext;
  23.     
  24.     public TableAdapter(Context context,List<double[]> mData){
  25.         this.mInflater = LayoutInflater.from(context);
  26.         this.mOriginalData = mData;
  27.         this.mContext = context;
  28.         
  29.                 
  30.         
  31.         toAllData();
  32.         
  33.     }
  34.     
  35.     private void toAllData(){

  37.         String[] tableTitle= new String[]{"日期","早餐前","早餐后1小时","早餐后2小时",
  38.                 "午餐前","午餐后1小时","午餐后2小时",
  39.                 "晚餐前","晚餐后1小时","晚餐后2小时",
  40.                 "睡前","凌晨2点"};
  41.         
  42.         for(int i = 0; i<tableTitle.length;++i){
  43.             mData.add(tableTitle[i]);
  44.         }
  45.         
  46.

  52.                 mData.add(""+fixedData[j]);
  53.             }
  54.         }
  55.     }
  56.     
  57.
