Android入门第五篇之TableLayout (二) .

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：

<?xmlversion="1.0"encoding="utf-8"?>
<LinearLayoutxmlns: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：

packagecom.LayoutDemo;
importcom.LayoutDemo.R;
importandroid.app.Activity;
importandroid.os.Bundle;
importandroid.view.ViewGroup;
importandroid.widget.TableLayout;
importandroid.widget.TableRow;
importandroid.widget.TextView;
publicclassLayoutDemoextendsActivity{
/**Calledwhentheactivityisfirstcreated.*/
privatefinalintWC=ViewGroup.LayoutParams.WRAP_CONTENT;
privatefinalintFP=ViewGroup.LayoutParams.FILL_PARENT;

@Override
publicvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//新建TableLayout01的实例
TableLayouttableLayout=(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(introw=0;row<10;row++)
{
TableRowtableRow=newTableRow(this);
for(intcol=0;col<8;col++)
{
//tv用于显示
TextViewtv=newTextView(this);
tv.setText("("+col+","+row+")");
tableRow.addView(tv);
}
//新建的TableRow添加到TableLayout
tableLayout.addView(tableRow,newTableLayout.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：
