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： 
view plaincopy to clipboardprint?
<?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 plaincopy to clipboardprint?
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：
