本文介绍如何通过代码在TableLayout中动态添加数据，演示了如何创建一个包含10行8列的表格，并展示了具体的XML布局文件及Java实现代码。

上一篇文章，主要将如何UI设计器设计TableLayout + TableRow，由于实际应用中，经常需要在代码里往TableLayout添加数据(9宫图也可以用TableLayout做出来 )，本文就是介绍这方面的简单使用方法。

main.xml的代码如下，用到TableLayout的ID为TableLayout01：

view plain copy to clipboard print ?

<? xml version = "1.0" encoding = "utf-8" ?>
< LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
android:orientation = "vertical"
android:layout_width = "fill_parent"
android:layout_height = "fill_parent"
>
< TableLayout
android:id = "@+id/TableLayout01"
android:layout_width = "fill_parent"
android:layout_height = "wrap_content" >
</ TableLayout >
</ LinearLayout >

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TableLayout android:id="@+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="wrap_content"> </TableLayout> </LinearLayout>

JAVA代码如下：

view plain copy to clipboard print ?

package com.LayoutDemo;
import com.LayoutDemo.R;
import android.app.Activity;
import android.os.Bundle;
import android.view.ViewGroup;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;
public class LayoutDemo extends Activity {
/** Called when the activity is first created. */
private final int WC = ViewGroup.LayoutParams.WRAP_CONTENT;
private final int FP = ViewGroup.LayoutParams.FILL_PARENT;
@Override
public void onCreate(Bundle savedInstanceState) {
super .onCreate(savedInstanceState);
setContentView(R.layout.main);
//新建TableLayout01的实例
TableLayout tableLayout = (TableLayout)findViewById(R.id.TableLayout01);
//全部列自动填充空白处
tableLayout.setStretchAllColumns(true );
//生成10行，8列的表格
for ( int row= 0 ;row< 10 ;row++)
{
TableRow tableRow=new TableRow( this );
for ( int col= 0 ;col< 8 ;col++)
{
//tv用于显示
TextView tv=new TextView( this );
tv.setText("(" +col+ "," +row+ ")" );
tableRow.addView(tv);
}
//新建的TableRow添加到TableLayout
tableLayout.addView(tableRow, new TableLayout.LayoutParams(FP, WC));
}
}
}

package com.LayoutDemo; import com.LayoutDemo.R; import android.app.Activity; import android.os.Bundle; import android.view.ViewGroup; import android.widget.TableLayout; import android.widget.TableRow; import android.widget.TextView; public class LayoutDemo extends Activity { /** Called when the activity is first created. */ private final int WC = ViewGroup.LayoutParams.WRAP_CONTENT; private final int FP = ViewGroup.LayoutParams.FILL_PARENT; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //新建TableLayout01的实例 TableLayout tableLayout = (TableLayout)findViewById(R.id.TableLayout01); //全部列自动填充空白处 tableLayout.setStretchAllColumns(true); //生成10行，8列的表格 for(int row=0;row<10;row++) { TableRow tableRow=new TableRow(this); for(int col=0;col<8;col++) { //tv用于显示 TextView tv=new TextView(this); tv.setText("("+col+","+row+")"); tableRow.addView(tv); } //新建的TableRow添加到TableLayout tableLayout.addView(tableRow, new TableLayout.LayoutParams(FP, WC)); } } }

结果如下图：
