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：

<?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：

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：
