android中水平显示表格数据

今天工作任务提前完成了，就抽空更新一下博客，这篇博客以前我在其他论坛上发表过，今天有空就把它拉过来；制作表格一般来讲都是一条一条数据垂直显示，今天我们就将表格数据水平分布显示；下面请看效果图：

一、两种实现方法

1.通过list数据源在textview中进行横向赋值操作。

大家先看看布局文件:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/relativeLayout1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/detail_project1_tv"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:text="项目"
        android:textSize="20sp"
        android:background="@drawable/textviewborder"
        android:gravity="center"
        android:textColor="@color/black" />

    <TextView
        android:id="@+id/detail_params1_tv"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:text="参数"
        android:textSize="20sp"
        android:background="@drawable/textviewborder"
        android:gravity="center"
        android:textColor="@color/black"  />

    <TextView
        android:id="@+id/detail_project2_tv"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:text="项目"
        android:textSize="20sp"
        android:background="@drawable/textviewborder"
        android:gravity="center"
        android:textColor="@color/black" />

    <TextView
        android:id="@+id/detail_params2_tv"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:text="参数"
        android:textSize="20sp"
        android:background="@drawable/textviewborder"
        android:gravity="center"
        android:textColor="@color/black" />

</LinearLayout>

给textview加上边框：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#00000000" />
<stroke android:width="2dip" android:color="#3B536E" />
</shape>

布局文件没什么多讲的，很简单，一目了然。

再看看adapter代码：

public class OrderMealDetailAdapter extends BaseAdapter {
    private LayoutInflater mInflater;
    public Context context;
    public List<NutrientContent> nutrientList = null;

    public OrderMealDetailAdapter(Context context) {
        this.context = context;
        this.mInflater = LayoutInflater.from(this.context);
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        if (nutrientList != null)
            return nutrientList.size();
        else
            return 0;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        if (nutrientList != null)
            return nutrientList.get(position);
        else
            return null;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        if (nutrientList != null)
            return position;
        else
            return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        Holder holder = null;
        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.ordermeal_detail_item,
                    null);
            holder = new Holder();
            holder.detail_project1_tv = (TextView) convertView
                    .findViewById(R.id.detail_project1_tv);
            holder.detail_params1_tv = (TextView) convertView
                    .findViewById(R.id.detail_params1_tv);
            holder.detail_project2_tv = (TextView) convertView
                    .findViewById(R.id.detail_project2_tv);
            holder.detail_params2_tv = (TextView) convertView
                    .findViewById(R.id.detail_params2_tv);
            convertView.setTag(holder);
        } else {
            holder = (Holder) convertView.getTag();
        }

//换行进行横向数据填充
        if (position % 2 == 0) {
            //填充一行中前两个元素
            holder.detail_project1_tv
                    .setText(nutrientList.get(position).project);
            holder.detail_params1_tv
                    .setText(nutrientList.get(position).element);
            holder.detail_project1_tv.setVisibility(View.VISIBLE);
            holder.detail_params1_tv.setVisibility(View.VISIBLE);
            //填充一行中后两个元素
            if (nutrientList.size() > position + 1) {
                holder.detail_project2_tv.setText(nutrientList
                        .get(position + 1).project);
                holder.detail_params2_tv
                        .setText(nutrientList.get(position + 1).element);
                holder.detail_project2_tv.setVisibility(View.VISIBLE);
                holder.detail_params2_tv.setVisibility(View.VISIBLE);
            } else {
                //没有可填充数据
                holder.detail_project2_tv.setText("");
                holder.detail_params2_tv.setText("");
            }
        } else {
            //把后一行的数据移到前一行来，后一行隐藏操作
            holder.detail_project1_tv.setVisibility(View.GONE);
            holder.detail_params1_tv.setVisibility(View.GONE);
            holder.detail_project2_tv.setVisibility(View.GONE);
            holder.detail_params2_tv.setVisibility(View.GONE);
        }
        return convertView;
    }

    class Holder {
        TextView detail_project1_tv; // 项目1
        TextView detail_params1_tv; // 参数1
        TextView detail_project2_tv;
        TextView detail_params2_tv;
    }

    // 退出
    public void exit() {
        nutrientList = null;
        notifyDataSetChanged();
        mInflater = null;
        context = null;
    }
 

看到注释大家都明白了吧，哈哈，有什么疑问大家可以留言；

PS：例子里面仅使用了表格水平排列2排的操作，如果大家有N排的操作，大家只需要修改布局文件添加N个TextView，然后在getView中if(position%2==0)中做N次判断就ok了。

2.通过循环，迭代tablerow进行横向赋值。
