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

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    
    <TextView 
        android:id="@+id/textview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="测试表格"/>
    
    <HorizontalScrollView 
        android:layout_width="match_parent" 
        android:layout_height="wrap_content"> 
        <LinearLayout 
            android:layout_width="match_parent" 
            android:layout_height="wrap_content" 
            android:orientation="vertical" > 
            <GridView 
                android:id="@+id/table_grid"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:horizontalSpacing="1dp"
                android:verticalSpacing="1dp"
                android:numColumns="12">
            </GridView> 
        </LinearLayout> 
    </HorizontalScrollView>
</LinearLayout>

2、表格中一个item的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="80dp"
    android:layout_height="match_parent"
    android:orientation="vertical">
    
    <TextView 
        android:id="@+id/text_item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:layout_gravity="center"
        android:textSize="15dp"
        android:textColor="#000000"></TextView>
    
</LinearLayout>

3、Adapter代码

package com.example.achartenginetest.adapter;
import java.util.ArrayList;
import java.util.List;
import android.content.Context;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
import com.example.achartenginetest.R;
public class TableAdapter extends BaseAdapter {
    private final static int NUM_COLUMN = 12;
    
    private LayoutInflater mInflater;
    private List<double[]> mOriginalData;
    private List<String> mData;
    private Context mContext;
    
    public TableAdapter(Context context,List<double[]> mData){
        this.mInflater = LayoutInflater.from(context);
        this.mOriginalData = mData;
        this.mContext = context;
        
                
        
        toAllData();
        
    }
    
    private void toAllData(){
        mData = new ArrayList<String>();
        String[] tableTitle= new String[]{"日期","早餐前","早餐后1小时","早餐后2小时",
                "午餐前","午餐后1小时","午餐后2小时",
                "晚餐前","晚餐后1小时","晚餐后2小时",
                "睡前","凌晨2点"};
        
        for(int i = 0; i<tableTitle.length;++i){
            mData.add(tableTitle[i]);
        }
        
        
        for(int i = 0; i<mOriginalData.size();++i){
            double[] fixedData = fixData(mOriginalData.get(i));
            mData.add(""+i);
            
            for(int j = 0; j<fixedData.length; ++j){
                mData.add(""+fixedData[j]);
            }
        }
    }
    
    
    /**
     * 检查数据长度是否为11个取值点
     * @param data
     * @return 0：11个取值点，1：大于11个取值点，-1：小于11个取值点
     */
    private int checkData(double[] data){        
        return data.length == NUM_COLUMN-1?0:(data.length<NUM_COLUMN-1?-1:1);
    }
    
    
    /**
     * 对数据进行修正，保证数据长度的正确性
     * @param data
     * @return
     */
    private double[] fixData(double[] data){
        int checkResult = checkData(data);
        if(checkResult == 0){
            return data;
        }else{
            double[] result = new double[NUM_COLUMN-1];
            
            if(checkResult == -1){                
                for(int i =0; i<data.length;++i){
                    result[i]=data[i];
                }
                
                for(int i = data.length; i<NUM_COLUMN-1; ++i){
                    result[i] = 0;
                }
                
            }else{                
                for(int i =0; i<NUM_COLUMN-1;++i){
                    result[i]=data[i];
                }
            }
            
            return result;
        }        
    }
    
    public int getDataCount() {
        return mOriginalData.size();
    }
    @Override
    public int getCount() {
        return mData.size();
    }
    @Override
    public Object getItem(int position) {
        return mData.get(position);
    }
    @Override
    public long getItemId(int position) {
        return position;
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        if (convertView == null) {           
            holder = new ViewHolder(); 
 
            convertView = mInflater.inflate(R.layout.table_item, null);
            holder.vText = (TextView)convertView.findViewById(R.id.text_item);
            
            convertView.setTag(holder);
        }else {
            holder = (ViewHolder)convertView.getTag();
 
        }
 
        holder.vText.setText(mData.get(position));
        
        if(position % NUM_COLUMN == 0){
            convertView.setBackgroundColor(Color.WHITE);
        }else if(position % NUM_COLUMN == 1 || position % NUM_COLUMN == 2 || position % NUM_COLUMN == 3){
            convertView.setBackgroundColor(Color.YELLOW);
        }else if(position % NUM_COLUMN == 4 || position % NUM_COLUMN == 5 || position % NUM_COLUMN == 6){

    }
    
    
    private class ViewHolder{
        public TextView vText = null;
    }
}

4、Activity代码

package com.example.achartenginetest.charts;

public class TableChart extends Activity{
    private GridView mGridTable;
    private TableAdapter mAdapter;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);        
        this.setContentView(R.layout.activity_table);
        
        
        mGridTable = (GridView)this.findViewById(R.id.table_grid);
        
        List<double[]> vlist = initList();        
        mAdapter = new TableAdapter(this,vlist);
        mGridTable.setAdapter(mAdapter);
        
        DisplayMetrics dm = new DisplayMetrics();   
        getWindowManager().getDefaultDisplay().getMetrics(dm);   
        float density = dm.density;   
        int gridviewWidth = (int) (90 * 12* density);   
        int itemWidth = (int) (80 * density); 
        
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(gridviewWidth , LinearLayout.LayoutParams.MATCH_PARENT);   
        mGridTable.setLayoutParams(params); 
        mGridTable.setColumnWidth(itemWidth);  
        mGridTable.setStretchMode(GridView.NO_STRETCH);   
        mGridTable.setNumColumns(12); 
        
    }
    
    
    private  List<double[]> initList(){
        List<double[]> vList =  new  ArrayList<double[]>();
        vList.add(new double[]{8.5,11.2,10.3,8.2,15,10.2,8.1,12,9.8,8.6,8.5});
